Indonesian Tumpangsari hutan merupakan suatu penerapan konsep agroforestry yang telah berjalan lebih dari satu abad sejak Buurman memperkenalkannya pada tahun 1873. Permasalahan yang dirasakan pada penerapan metoda tumpangsari dalam sistem peremajaan hutan dewan ini adalah adanya gejala semakin langkanya pekerja hutan yang dapat dikontrak sebagai pembuat tanaman. Kesulitan itu disinyalir disebabkan adanya kecenderungan penurunan produktivitas lahan sehingga pendapatan pesanggem dari hasil usahataninya berkurang. Di pihak lain metoda peremajaan ini merupakan metoda peremajaan hutan yang diandalkan karena kelebihan-kelebihannya dibanding dengan metoda peremajaan yang lain. Penelitian ini bertujuan untuk memperoleh gambaran mengenai keragaan tumpangsari hutan terutama yang berhubungan dengan perubahan penerimaan dan biaya, resiko dan respon dari faktor-faktor produksi terhadap hasil sebagai akibat adanya perubahan teknik berproduksi dari tumpangsari tradisional ke Inmas tumpangsari. Untuk sampai pada tujuan tersebut telah digunakan metoda analisis budget, pembandingan koefisien variasi (CV), dan analisis fungsi produksi. Hasil penelitian menunjukkan bahwa penerimaan atas biaya tunai meningkat sebesar 75 persen dan 13 persen masing-masing untuk perubahan tumpangsari tradisional ke Inmas tumpangsari pada lahan bonita 3 dan bonita 4. Resiko yang dihadapi dalam usahatani tumpangsari cukup tinggi seperti tergambar dalam CV yang pada umumnya lebih dari 40 persen. Elastisitas penerimaan atas biaya tunai (dihitung dengan metoda aritamtik biasa) terhadap perubahan biaya yang dikeluarkan untuk pupuk dan pestisida adalah 45 persen dan 22 persen masing-masing untuk perubahan tumpangsari tradisional ke Inmas pada lahan bonita 3 dan bonita 4. Adapun hasil pengujian statistik dari fungsi produksi, secara parsial tidak menunjukkan adanya pengaruh yang berarti dari setiap masukan usahatani dan jarak antara lahan andil dengan rumah petani. Walaupun begitu, pengaruh peubah-peubah bebas tersebut secara sekaligus keseluruhan menunjukkan pengaruh yang nyata pada tingkat kepercayaan 99 persen.

Renal function evaluation with the use of radio nuclide scanning is a very helpful technique. Renogram is a routine procedure in the Institute of Nuclear Medicine and Allied Sciences (INMAS), Sylhet. This is a tertiary referral hospital to north east part of the country. The aim of this study was to analyze the renal disease pattern and outcome of diuretic renogram of different types of renal diseases. This retrospective study was conducted among 223 patients who underwent 99mTc-DTPA renogram from February to October 2018 in INMAS, Sylhet. Mean age of the patients was 30.04 ± 18.52 year with age range 1 to 80 years, male to female ratio 1.5:1. USG. Clinical information and other adjuvant findings along with the ultrasound findings were collected to categorize the study subject. Most common indication for the renogram was hydronephrosis (HDN) 80.27%, followed by smaller kidney 7.17%, renal parenchymal disease 3.14%, nephrolithiasis 3.14% and others (renal cysts and renal artery stenosis). The mean and standard deviation of serum creatinine was 0.9 ± 0.51, range from 0.30 to 4.50. Among the 179 HDN patients, mild, moderate and severe cases were 37 (20.7%), 44 (24.6%) and 81 (45.3%) respectively. Most common site of involvement was left kidney (n=90, 41.3%), followed by both kidneys (n=67, 30.7%). Overall renographic findings showed obstructive disease in 144 (66.05%) patients and non- obstructive disease in 74 (33.94%) patients. It concluded that isotope renogram is very important in the evaluation of renal function especially differentiate between obstructive from non-obstructive pathology.

Breast cancer is the most common malignant tumor of females, the incidence increases with age. Bone is the most common site to which breast cancer metastasizes. Between 30% to 85% of patients with metastatic breast cancer develop bone metastases during the course of the disease. Bone scan is the most commonly used means of detecting bone metastasis; it visualizes increases in osteoblastic activity and skeletal vascularity. Many radio-pharmaceuticals (radionuclides) have been used in bone scan including technetium-99m bound to methylene diphosphonate (MDP). Published sensitivity and specificity rates of bone scan for diagnosis varies, with sensitivity ranging from 62% to 100% and specificity from 78% to 100%. However, bone scan is generally considered sensitive for detecting bone metastases on whole-body images.The aim of this study was to evaluate the pattern of distribution of skeletal metastases in patients with breast carcinoma by using Tc-99m MDP bone scan. A retrospective study was conducted on 245 consecutive female breast carcinoma patients irrespective of clinical staging, menopausal status and pre-operative / post- mastectomy status, referred for bone scan to Institute of Nuclear Medicine and Allied Sciences, Rajshahi from July 2015 to June 2017. The mean age of the patients was 43.4 ± 13.8 years (mean ± SD) with range from 29 to 66 years. Bone scan was performed by an intravenous bolus injection of 20 mCi Tc99m-MDP. Bone phase images were taken at three hours after injection of the radiotracer. Out of 245 studied patients, 163 patients (66.53%) were negative for skeletal metastasis and 82 patients (33.47%) were positive for skeletal metastasis. Out of 82 patients with positive skeletal metastasis, 68 (82.93%) patients had multiple sites (two or more) and 14 (17.07%) patients had solitary site of bony involvement. Out of 68 patients with multiple sites of skeletal metastasis, highest number was noted in thoraco-lumbar spine (80.89%), followed by ribs including sternum and clavicle (57.35%), pelvic bones (47.06%), upper extremities including scapula (41.18%), lower extremities (33.82%), cervical spine (23.53%) and skull bone (8.82%). Among 14 patients with solitary skeletal metastasis, maximum number was noted in thoraco-lumbar spine (64.29%), followed by cervical spine (14.29%), pelvic bone (07.14%), ribs (07.14%) and sternum (07.14%). Skeletal metastases were much more common in multiple sites than solitary lesion in breast cancer patients. Thoraco-lumbar spine was the most common site of involvement in both solitary and multiple lesions in our study. Axial skeleton was more commonly involved than the appendicular skeleton. Bone scan may pick up bone metastases up to 18 months earlier than conventional radiology, with an average lead of four months. 99m Tc- MDP bone scan is very cost effective in comparison to other imaging modalities (CT, MRI, and PET) and play a major role in early detection of skeletal metastasis in breast cancer patients.

Background: Invasive Ductal Carcinoma (IDC) is the most common of all diagnosed breast cancers, and it frequently presents with metastatic spread to the bone as well as other viscera. Bone scintigraphy is the primary tool for detecting bone metastases, while different imaging modalities can be useful in detecting visceral metastases. The purpose of this study was to determine the relationship between skeletal and visceral metastases in female patients with IDC referred to INMAS, Mitford, for bone scintigraphy. Patients and Methods: This observational study was conducted at the Institute of Nuclear Medicine and Allied Sciences (INMAS), Mitford, Dhaka, from July 2020 to July 2021. Bone scintigraphy was done with a Siemens dual-head gamma camera after an intravenous injection of 20 mCi of 99mTc-MDP. Both anterior and posterior views were obtained, with additional SPECT images when needed. Images were interpreted and analysed by Nuclear Medicine (NM) physicians of this institute. Data about visceral metastases were collected from patients’ record files. Results: The patients were divided into two groups based on the presence of visceral metastases. Group-A had 95 patients with no known metastases to the viscera, and in Group-B, there were 50 patients who had documented visceral metastases. The majority of the patients in the first group (53.7%) showed no bone metastasis, while a small portion (5.3%) revealed a solitary skeletal metastatic lesion and the rest (41.1%) presented with multiple skeletal metastases. Sixty-six percent of patients in Group B had solitary visceral metastases, with the remaining 34% having metastases to multiple viscera. All the patients in this group were affected at various levels by secondary skeletal deposits. Conclusion: The findings of the study revealed that the presentation of visceral metastases was related to the extent and severity of bone metastases in patients with carcinoma of the breast.

Nuclear Medicine workers are getting higher radiation dose because of increasing usage of nuclear medicine for diagnostic and therapeutic procedures. The purpose of the study is to monitor the real-time radiation at the indoor places of the Institute of Nuclear Medicine & Allied Sciences (INMAS) Mitford, Sir Salimullah Medical College and Hospital Campus for minimizing the ionizing radiation hazard to radiation worker and public. The radiation monitoring was performed using real-time portable digital radiation monitoring device. This real-time digital portable radiation monitoring device meets all European CE standards as well as the American “FCC 15 standard”. The portable radiation monitoring device was placed at 1 meter above the ground on tripod and data acquisition time for each monitoring point (MP) was 1 hour. 26 MPs were selected for collection of radiation dose rates at different indoor locations of INMAS, Mitford hospital. The measured dose rates due to natural and man-made radionuclides were ranged from 0.151 ± 0.070 μSv.h-1 to 4.313 ± 1.829 μSv.h-1 with an average of 0.456 ± 0.227 μSv.h-1. The annual effective dose to the radiation worker and public due to radiation were varied from 0.305 mSv to 8.764 mSv with an average of 0.951 mSv. Excess life-time cancer risk factor based on annual effective dose to radiation worker and public were calculated and varied from 1.213 Χ 10-3 to 3.486 Χ 10-2. Real-time radiation monitoring at indoor places of nuclear medicine facilities are required for minimizing unnecessary exposure to nuclear medicine workers and public from man-made sources. This kind of study is required for minimizing the radiation hazard in the hospital environment and consequently to keep the radiation dose to worker and public as low as possible.

Objective: Skeletal scintigraphy is highly sensitive and widely used for the detection of metastatic disease especially in breast cancer. The study was aimed to evaluate the pattern of skeletal metastasis in breast cancer patients with whole body bone scan using 99mTechnetium -Methyl Diphosphonate (99mTc-MDP) to aid proper diagnosis, staging, management and prognosis. Study design: Single center based retrospective study. Patients and methods: The study was conducted among the histopathologically proven breast cancer patients referred to INMAS, Barishal for 99mTc-MDP bone scintigraphy between March 2016 and March 2017. Bone scan was done with SPECT digital dual head gamma camera (Siemens S series) 3 hours after intravenous bolus injection of 20 mCi 99m Tc-MDP. Results: Out of total 96 patients, 47(49%) were found positive for skeletal metastases and among them 31(66%) had only axial skeletal metastases. Appendicular skeletal metastases were seen in 5 (11%) patients. Both axial and appendicular skeletal metastases were found in 11(23%) patients. Conclusion: For equivocal lesions SPECT is better than planar scintigraphy alone to characterize and comment confidently. Metastatic lesions detected by bone scintigraphy in breast cancer patients keep a significant impact on patient management. Bangladesh J. Nuclear Med. 23(1&2): 37-39, 2020

Thyroid tissue may be found in an abnormal location along the thyroglossal duct tract or other sites due to abnormal embryologic development and migration. Thyroid ectopia is an uncommon but well-documented clinical entity. In the event of any neck swelling, it should be kept as a differential diagnosis. Thyroid scintigraphy plays a very important role in diagnosing ectopic thyroid, with the complementary primary role of high-resolution neck ultrasonography (HRUS). Reported case of an 18-year-old male referred to INMAS for evaluation of a slowly enlarging submental swelling with no history of dysphagia or dyspnea was biochemically hypothyroid. Patient had a history of submental swelling that was misdiagnosed as an abscess, creating a diagnostic dilemma, as he was found to have glandular tuberculosis after surgical drainage of the lesion.

Indonesian Berbagai macam cara intensifikasi untuk meningkatkan produksi padi selah diterapkan. Pada MT 1980 secara besama-sama dilaksanakan usaha intensifikasi padi melalui Bimas dan Inmas (Inmum), Insus serta Opsus. Lebih jauh intensifikasi pada Insus dapat pula diklasifikasikan ke dalam Kelompok Tani (KT) Insus lomba dan KT Insus tidak lomba. Tentu dapat diharapkan produksi padi sebagai hasil dari berbagai macam intensifikasi ini akan berbeda-beda. Hasil telaahan di Klaten Jawa Tengah dan Tabanan Bali menunjukkan bahwa produksi dan pendapatan usahatani padi dengan Insus lebih tinggi dibandingkan dengan produksi dan pendapatan usahatani padi Inmum. Kejadian tersebut berlaku pula antara Insus lomba dan Insus biasa; Insus lomba lebih baik daripada Insus biasa. Perbedaan ini tidak nyata disebabkan oleh perbedaan dari penggunaan masukan ataupun biaya, tetapi lebih banyak disebabkan oleh baiknya penerapan Panca Usahatani dan dukungan aparat lembaga penunjang di desa. Telaahan ini memperlihatkan pula bahwa pengalaman petani berorganisasi dalam bentuk Subak di Bali lebih memperlancar dan menigkatkan kualitas pelaksanaan Insus.

Indonesian Kajian ini menggunakan data sekunder yang diperkaya dengan informasi kualitatif melalui wawancara untuk menganalisa penggunaan dan penyaluran pupuk di Wilayah Pemasaran Kalimantan Barat. Didapatkan bahwa pengalihan program Bimas ke Inmas mengakibatkan menurunnya secara tajam penggunaan berbagai jenis pupuk Sub Sektor Tanaman Pangan. Penyebabnya antara lain adalah besarnya kendala teknis budidaya, keadaan agroekologi yang kurang menguntungkan perkembangan tanaman pangan dan masih lemahnya persepsi petani tentang penggunaan berbagai jenis pupuk, khususnya TSP. Konsumsi pupuk Sub Sektor Perkebunan dalam jangka pendek akan dapat ditingkatkan dengan memperluas areal Perkebunan Besar Negara, berbagai proyek pengembangan komoditi perkebunan dan memantapkan pembinaan pemasaran komoditi swadaya seperti cengkih, lada dan jeruk. Bidang usaha penyaluran pupuk yang kurang emnarik di daerah ini dapat dirangsang diantaranya dengan meningkatkan margin penyaluran dan mengalihkan penjualan langsung oleh KPW Pusri kepada penyalur. Pemecahan kendala penyaluran pupuk dari Lini IV ke petani secara koordinatif diyakinkan akan dapat memperlancar penyaluran pupuk secara keseluruhan di daerah ini.

Salah satu upaya alternatif untuk meningkatkan kualitas lahan sawah yang telah terdegradasi adalah mengaplikasikan zeolit dan dolomit yang dikombinasi dengan pengelolaan bahan organik serta sistem pemupukan berimbang yang spesifik lokasi berdasarkan uji tanah dan kebutuhan tanaman. Pemanfaatan pembenah tanah untuk meningkatkan efisiensi pemupukan pada lahan sawah perlu dilakukan, sebab kegiatan intensifikasi dan estensifikasi pertanian dari program Bimas dan Inmas yang kurang mengindahkan kaidah pemupukan berimbang telah mengakibatkan semakin merosotnya kualitas lahan sawah, sehingga terjadi fenomena levelling off. Penelitian dilakukan di Lampung Tengah dengan tujuan 1) mengetahui tingkat efisiensi pemupukan di tingkat petani sebagai dampak dari penggunaan zeolit dan dolomit, : (2) mengetahui pengaruh pemberian zeolit dan dolomit terhadap perbaikan sifat-sifat tanah dan produktivitas lahan. Metode yang digunakan dalam penelitian ini adalah metode survei, yakni pengumpulan data dilakukan melalui wawancara dengan menggunakan kuisioner terstruktur guna mengungkap karakteristik petani, identifikasi, dan prospek zeolit dan dolomit di masa depan. Hasil penelitian diperoleh bahwa jenis zeolit dan dolomit yang dikenal dan digunakan adalah: Zeolit Agro 2000, ZP.30 (Zeolit yang diperkaya hara P) dan dolomit. Penggunaan zeolit dan dolomit bermanfaat untuk meningkatkan produksi tanaman padi sekitar 10-30%. One of alternative efforts to increase rice field soils quality which have degradated is through applying zeolit and dolomite combined with organic matter management along with spesific location balanced fertilizer system based on soil testing and nutrients need for the crop. Study of soil conditioner utilization for increasing fertilizer efficiency on paddy soils must be done, because agriculture intensive and extensive activity of Bimas and Inmas program did not considered the principles of balanced fertilizer which consequences the decreasing of paddy soils quality, finally lead to the occurrence a levelling off phenomenon. The research had been conducted in Centre Lampung district with the objectives, (1) to know fertilizer efficiency at the farmer level as the impact of zeolit and dolomite utilizing. (2) to know the efect of the soil physic and chemical and land productivity. The research method used was survey methods, its mean that data collected pass through interview with the structure questioner to know farmer’s characteristics, identification, and soils conditioner development prospect in the future. The results of this research found that, the kind of zeolit and dolomite which had been known and used were Zeolit Agro 2000, ZP.30 (enriched zeolit with P nutrient) and dolomite. Zeolit and dolomite utilization in both districts had benefit to increase rice crop production more or less 10-30%.

Berdasarkan survei yang dilakukan pada Juli 2017 bahwa data yang dimiliki oleh Kantor Wilayah Kementerian Agama Sumatera Barat, pondok pesantren yang ada di Sumatera Barat Tahun Pengajaran 2016/2017 berjumlah 211 lembaga. Saat ini informasi mengenai Pondok Pesantren terdapat pada website Education Management Informasion System (EMIS) dengan akses http://emispendis.kemenag.go.id. Namun dari website tersebut masyarakat hanya dapat informasi mengenai jumlah pondok pesantrennya saja sehingga masyarakat tidak mengetahui bagaimana situasi lingkungan yang ada pada pondok pesantren baik itu berupa peta, nama, nomor telepon, foto dan informasi-informasi lainnya. Untuk itu dilakukan penelitian guna memberikan solusi bagi masyarakat dan juga pihak Kantor Wilayah Kementerian Agama Sumatera Barat dalam melayani masyarakat terkait informasi pondok pesantren.

This study estimates the potential health risks attributed to the internal contamination of occupational workers at the Institute of Nuclear Medicine and Allied Sciences (INMAS) located at Dhaka Medical College and Hospital, Dhaka, during nuclear medicine practices involving the radionuclides 131I and 99mTc, using in vitro methods from urine samples. A total of 55 urine samples from 6 occupational workers are collected over a period of about 11 months. These samples are analyzed using a High Purity Germanium (HPGe) detector coupled with a multichannel analyzer (MCA). The radioactivity of the isotopes present in each urine sample is measured based on the detector efficiency, and the committed effective dose due to each intake is calculated from this activity. The average annual doses of individual workers found in this study range from 4.57 × 10-5 mSv to 9.72 × 10-3 mSv. Although these doses are considerably below the International Commission on Radiological Protection (ICRP) recommended annual dose limit of 20 mSv, efforts to abide by the ALARA principle should continue.

Background: Breast cancer is the most frequent female cancer, especially in 'developed' countries. 30-85% of metastatic breast cancer patients will develop bone metastases during the course of the disease. The study was aimed to evaluate the pattern of skeletal metastasis in breast cancer patients with whole body bone scan using 99mTechnetium methyl diphosphonate (99m'Tc-MDP). Methods: This single center based retrospective observational study was conducted among the histopathologically proven breast cancer patients referred to INMAS, Rangpur for 99m'Tc-MDP bone scintigraphy between March 2015 and March 2019. Bone scan was done with SPECT digital dual head gamma camera (Siemens S series) 3 hours after intravenous bolus injection of 20 mci99mI'c-MDP. Results: Out of total 300 patients, 120 (40%) patients were found secondaries in bones. Among them 80(66.7%) had only axial skeletal metastases and 15 (12.5%) had appendicular skeletal metastases. Both axial and appendicle skeletal metastases were found in 25 (20.8%) patients. Conclusion: Thoraco-lumbar spine was the most common site of involvement in our study.

Background: Lung cancer is the leading cause of cancer deaths worldwide. Lung cancer is often insidious, producing no symptoms until the disease is well advanced. In approximately 7-10% of cases, lung cancer is diagnosed in asymptomatic patients. Some patients are asymptomatic for skeletal metastasis and a recent prospective study showed that in staging of non-small cell lung cancer (NSCLC), failure to perform a bone scan could miss asymptomatic bone metastasis in 14–22% of patients. Radionuclide bone scintigraphy with 99m Tc MDP (Technetium-99mmethylene diphosphonate) is very useful nuclear imaging tool to detect skeletal metastasis with a sensitivity of 98.2% and a specificity of 95.2%. The aim of this study was to detect the asymptomatic skeletal metastasis of non-small cell lung cancer patients by 99mTc MDP bone scan.Patients and methods: It is a retrospective study, carried out from January 2015 to December 2016 in Institute of Nuclear Medicine and Allied Sciences, Rajshahi. Bone scan was performed by an intravenous bolus injection of 20 m Ci 99mTc MDP. Bone phase images were taken at three hours after injection of the radiotracer.Results: A total of 52 patients were enrolled in the study. The mean age of the patients was 57.6 ± 14.5 years (mean ± SD) with range from 36 to 75 years and 42 (80.77%) were male and 10 (19.23%) were female. Out of 52 patients, only 06 (11.54%) patients were diagnosed as positive and 46 (88.46%) were negative for bone metastasis. Out of 06 patients with positive skeletal metastasis 04 (66.67%) patients had multiple sites (two or more) and 02 (33.33%) patients had solitary site of bone involvement. Common sites of metastasis were in thoracic (83.33%) and lumbar spine (83.33%), ribs (50%), pelvic bones (33.33%), long bones (16.66%), skull (16.66%) and other bony sites including clavicle, sternum, scapula, sacrum (16.66%). Regarding staging prior to bone scan, out of 06 bone scan positive patients 03 (50%) patients were in stage III, 02 (33.33%) patients were in stage IV and 01(16.67%) patient was in stage II. On the basis of histopathology, out of 06 skeletal metastatic patients 04 (66.67%) patients had adenocarcinoma, 01 (16.67%) patient had squamous cell carcinoma and 01 (16.67%) had large cell carcinoma. The exclusion of bone metastasis is important in the initial staging of non-small cell lung cancer.Conclusion: There is debate about whether bone scans should be performed routinely or restricted to patients who present with clinical or laboratory indicators suggesting skeletal metastasis. The present study indicates that if bone scans were done only in patients reporting skeletal symptoms an important number of patients (11.54%) would have been miss-staged due to asymptomatic bone metastasis. As bone scan is very cost effective in comparison to other imaging modalities (MRI / PET-CT), it can play a vital role in detecting asymptomatic skeletal metastasis in NSCLC patients.Bangladesh J. Nuclear Med. 20(2): 110-114, July 2017

Background: Hyperthyroidism is a morbid condition. Radioiodine therapy is very safe, popular and effective treatment of hyperthyroidism. This study was design to determine the outcome of fixed dose radioiodine (RAI) therapy in hyperthyroid patients in a single institute. Patients and Methods: This was a retrospective study conducted from January 2014 to December 2016 at 1Institute of Nuclear Medicine and Allied Sciences, Sir Salimullah Medical College Campus, Mitford, Dhaka. A total 71 patients were enrolled for this study. All the patients were pretreated with antithyroid drugs than underwent fixed dose of RAI therapy. They were followed up at regular interval. Chi-square and paired t test was done to see the level of significance. Results: Mean age of the patients were 41.61 years (range 19-60 years). Male were 29 (40.8%) and female were 42 (59.2%). Mean months of pretreated with antithyroid drugs were 30.59 ± 23.68 months, range (2-96 months). Before RAI therapy mean TSH was 0.12 ± 0.14 μ IU/ml range (0.0001-0.54 μIU/ml) and after RAI therapy mean TSH was 1.6 ±1.5μ IU/ml range (0.002-5.00 μIU/ml). Before RAI therapy mean FT4 was 26.26 ±10.25 fmol/ml, range (7.86-47.78 fmol/ml ) and after RAI therapy mean FT4 was 23.45±8.22 fmol/ml, range (8.78-40.45 fmol/ml). All patients diveided into three groups: Graves’ disease (29), toxic multinodular goiter ( 28) and toxic autonomous nodule (14). After three years of follow up 27 (38%) patients were euthyroid, 2 (2.8%) remain hyperthyroid, 3(4.2%) were relapse cases and 39 (54.9%) were hypothyroid. Conclusion: This follow up study showed that patients treated with RAI therapy became hypothyroid in the long run. Relapse and persistent hyperthyroid state were very common phenomenon after RAI therapy. Bangladesh J. Nuclear Med. 21(1): 8-11, January 2018

Background: Radioiodine therapy is very effective and popular method of choice for the treatment of carcinoma thyroid. Dry mouth is acommon side effects after radioiodine therapy and sequel of the salivary gland dysfunction. Many of the patients are suffering from this side effect. This study was designed to evaluatethe functionof the salivary gland of the patients treated with radioiodine therapy. Materials and methods: This cross sectional study was done in the Institute of Nuclear Medicine and Allied Sciences Mitford Dhaka for about 06 months from August 2019 to March 2020. About 51 patients were enrolled for this study having single dose of radioiodine therapy. Dynamic sialo scintigraphy with citrus stimulation was done after intravenous injection of 02 mci of Tc-99m. After 10 minutes of dynamic study lemon juice was given orally for the augmentation of the gland function. Result was interpreted as salivary gland dysfunction when a curve was uprising after lemon juice augmentation and normal functioning when fall off curve. Then data were compiled and analyzed by SPSS version 22. Results: The mean age of the study subjects were 35.1 ± 9.8, age ranged from 14~56 years, sixwere male and 45 were female participants. The mean dose was 4.3±1.1GBq, ranges from 1.8~7.4GBq. The proportion of salivary gland dysfunction was 60.8% while 39.2% had normal salivary gland function.Right salivary gland dysfunction was found in52.9% patients while 54.9% patient showed left salivary gland dysfunction. A little above a decile (13.7%) showed right submandibular gland dysfunction while a little less than that(7.8%) showed left submandibular gland dysfunction. Salivary gland dysfunction was related to the dose of the radioiodine therapy (p<0.5). Higher dose of RAIT produced the odds of dysfunction in right parotid gland as 1.01, that of left parotid as 0.04, that of right submandibular as 0.09and that of left submandibular 0.60. Conclusion: Higher dose of radioiodine therapy was related with salivary gland dysfunction Bangladesh J. Nuclear Med. 24(1&2): 36-41, 2021

This paper aims to comprehensively address the important role of accelerating the application of location-specific technological innovations as one indicator of realizing agricultural and rural development. The implementation of agricultural development has had a real impact on socio-economic changes in rural communities. Food security and farmer and rural welfare still remain a strategic problem. Programs and policies that introduce various technologies to increase rice production and productivity have been carried out by the government. Some of them are about the Green Revolution, the Bimas Inmas program, the rice SL-PTT program, the rice intensification program (IP-400, SRI, P4 MI and others. This paper is part of various research results, one of which is PATANAS: Indicators of Agricultural and Rural Development, which is supported and enriched with various data and information related to the purpose of writing. The use of organic fertilizers is highly recommended because it is very useful for improving soil structure as a source of micro nutrients and as a medium for soil microbes development. During the past decade the use of seeds labeled by farmers has increased, including the existence of aid programs and subsidized seed prices. Labeling whether or not rice seeds are used by farmers is positively correlated with procurement source. Empirical facts show that the increasing conversion of agricultural land to non-agriculture threatens the existence of the agricultural sector in terms of national food security. Innovations implementation considering the specific location should be carried out as early as possible

With an aging population, osteoporosis is increasingly becoming a public health concern. Bangladesh has a high incidence of osteoporosis and occurs among a relatively younger age group than in the developed world. There are several factors that could be associated with bone mineral density (BMD). We are keen to determine the association with BMD and BMI. The study was carried out on 152 patients who were referred to INMAS for dual energy X- ray absorptiometry (DEXA) measurement of bone mineral density (BMD) during the periods of January 2018 to July 2019. BMD was measured at right femoral neck and lumbar spines. Data about age and sex, BMI were recorded. Reporting was done according to the T score following WHO criteria. Prevalence were compared using chi-squared tests. Among 152 patients, 84.9% were females and 15.1% were males. Results showed for right femur that normal bone density in 91 (59.1%), osteopenia in 54 (35.1%), osteoporosis in 9 (5.8%) and BMD in spine was normal in 57 (37.0%) osteopenia in 44 (28.6%), osteoporosis in 53 (34.4%). About 60% of the study population was normal weight and others were underweighted or overweighed. Status of BMD was associated with BMI in the lumbar spine and femur. In this study group, total 61.2% and 26.3%were found low BMD in spine and right femur respectively. In age group ≥ 60 years, low BMD in spinewas 72.0% that is 42.29% higher compare to below 60 years’ group (50.6%).Correlation of BMI with lumbar spine T score, right femur and left femur T score were measured by Pearson’s correlation coefficient test. Positive significant Pearson’s correlation was observedbetween BMI with spine T score (r = 0.397; p = <0.001), BMI with right femur T score (r = 0.347; p = <0.001) and BMI with left femur T score (r = 0.382; p = <0.001).

The main quality controls of hybrid SPECT/CT are Uniformity and Multiple Head Registration (MHR)/Centre of rotation (COR). Uniformity corrects and verifies cameras response to uniform distribution of radionuclides on the detector surface. MHR/COR not only observes mechanical errors but also quantitatively corrects the errors due to movement of patients and detectors onthe SPECT images. The aim of the study is to establish baseline values thatcan be used as reference for future quality assurance and to verify the manufacturers specification. Both intrinsic and extrinsic Uniformity were measured by using 18?Ci 99mTc point source and 35mCi 99mTc flood source respectively. For MHR/COR measurements, MHR Phantom containing five approximately equal strength (1 mCi99mTc of each) point sourceswere used. The values were found to be in correlation with manufacturers specification. DOI: http://dx.doi.org/10.3329/bjnm.v17i1.22494 Bangladesh J. Nuclear Med. 17(1): 67-74, January 2014

Objective: Radioactive iodine therapy (RIT) is the most commonly used modality to treat hyperthyroidism and is indeed in most cases, the treatment of choice. The aim of this study was to assess the clinical outcome one year after radioactive Iodine-131 (RAI -131) therapy and to identify the factors associated with response of the therapy.Patients and Methods: A total 107 hyperthyroid patients were included in this study. All patients were pre-treated with anti-thyroid drugs (ATD). A fixed dose of 8 mCi of radioiodine was given to the patients with Graves’ disease, 12 mCi to patients with single toxic adenoma and 15 mCi to patients with toxic multi-nodular goiter . The patients were done serum FT4 initially and followed up with serum T3, T4, and TSH at three months , six months and one year of RAI therapy . The clinically and biochemically euthyroid and hypothyroid patients were considered as cure of the disease.Results : The cure rate was about 94.7% seen in female patients and 93.8% in male ( P=0.92), 93.6% in younger age group (below 40 years) and 95.0% of the older patients ( P=1.51), 95.5% of the patients who were taking ATD for more than one year and 92.7% of the patients who were taking ATD for less than one year before therapy( P=1.95), 95.4 % of the patients who had initial FT4 level less than 35 pmol/L and 92.7 % of the patients who had high initial FT4 ( P=1.54). Cure rate of Graves’ disease was 45/53 (92.5%), multi-nodular goiter 41/43 (95.3% ) and for single toxic adenoma was 11/11 (100% ) (P= 0.65). The incidence of radioiodine induced hypothyroidism was 6.5 % at three months, 13.1 % at six months and 15.0 % at one year. Overall incidence of cure rate of RAI therapy after one year was 101 (94.4 %).Conclusion: No statistically significant difference was found in the cure rate when sex, age, duration of pretreatment with antithyroid drug, initial FT4 level and cause of hyperthyroidism were considered. From this study it can be concluded that cure rate of RAI therapy is quite good and the pretreatment factors have little influence on the final outcome.Bangladesh J.

Back ground: Non-Alcoholic Fatty Liver Disease (NAFLD) is a common cause of Chronic Liver Disease (CLD) worldwide and is becoming a major public health problem. NAFLD has been recognized as a hepatic manifestation of Metabolic Syndrome (MetS) linked with Insulin Resistance (IR) and is currently considered as the hepatic component of the Metabolic Syndrome (MetS). NAFLD is strongly associated with IR and is mostly silent which is often discovered incidentally through elevated hepatic enzyme levels. The purpose of this study is to find out the association of Fasting Lipid Profile (FLP) with IR in NAFLD subjects. Materials and methods: A prospective hospital based cross sectional study was carried out in the Department Of Biochemistry, Institute of Nuclear Medicine and Allied Sciences (INMAS) and Chittagong Medical College Hospital. One hundred & fifty (150) subjects aging between 18-60 years were included in this study by non probability consecutive sampling method. Important variables in this study were Fasting Plasma Glucose (FPG) Fasting Serum Insulin (FPI) and Fasting Lipid Profile (FLP). IR was calculated by using Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) index i.e. (FPI μIU x FPG mmol/L)/22.5. Results: In this study HOMA-IR was significantly higher in cases than that of controls (4.77±0.16) and showing Insulin Resistance (IR) in 90% of the cases. There was a significant association of HOMA-IR with increased serum Triglyceride (TG) in NAFLD cases. Conclusion: The findings of the current study suggest that independent variable such as increased Serum TG was associated with IR in NAFLD subjects.

Abstract In this work, the process of phosphorus desorption from epi-ready InP(001) substrates during high-temperature annealing in an arsenic flux was experimentally investigated. An InPAs solid solution and InAs islands were formed on the surface upon annealing. The composition of the solid solution, the surface area fraction occupied by InAs islands, and its height depend on the annealing temperature. The phosphorus desorption rate was determined from the dependence of the arsenic atoms number on the substrate surface on the annealing temperature and the holding time in the arsenic flux. The phosphorus desorption rate increased from 6.03×1010 s−1⋅ cm−2 at an annealing temperature of 500 °C to 4.38×1011 s−1 ⋅ cm−2 at 540 °C. The activation energy of the phosphorus desorption process was 2.7 ± 0.2 eV.

Objective: Lung carcinoma is the most common cancer worldwide with high potentiality of being metastasized to bone. Technetium-99m methylene diphosphonate (99mTc MDP) bone scintigraphy is a sensitive nuclear medicine imaging study to detect the skeletal metastases. The utilization of bone scan upon diagnosis of lung cancer appears to help in accurate staging of patients and planning treatment. The aim of the present study was to see the role of baseline bone scintigraphy in the newly diagnosed lung carcinoma patients and also to see the number, pattern and sites of involvement of bone as well as to evaluate the skeletal metastases according to the different histological types of lung carcinoma.Patients and Methods: This observational study was carried out at the Institute of Nuclear Medicine & Allied Sciences (INMAS), Sylhet during the period of July 2014 to June 2015. A total number of 59 lung carcinoma patients who attended at the scintigraphy division of INMAS, Sylhet within three months of their histopathological diagnosis were included in this study. Clinical staging was done from clinical evaluation (history and physical examination) and also form available investigation reports. Skeletal scintigraphy was performed by dual-head gamma camera using low-energy all purpose collimator, 2-3 hours after IV administration of 20-30 mCi of 99mTc MDP. Interpretation was done by recording the distribution of radiotracer within the skeleton along with correlation of history, physical examination, FNAC or biopsy reports and other relevant investigation findings.Results: Out of 59 patients, 43 (72.9%) were male and 16 (27.1%) were female. The age range of the patients was from 37 to 85 years with a mean (± SD) of 59.10 ± 10.43 years. The rate of lung carcinoma was highest in the age group of 55-64 years (45.7%), followed by 45-54 years (27.1%) and 65-74 years (11.9%). Incidence was lowest in patients below 45 years (6.8%) and above 75 years (8.5%). Skeletal metastases were detected in 52.54% of lung carcinoma patients where multiple lesions were seen in 87.1% of cases and solitary lesion in 12.9%. Among the metastatic lesions, 82.9% lesions were distributed in axial skeleton and 17.1% lesions were distributed in appendicular skeleton. Spine was the most frequent site of metastatic involvement in the present study which was 37.8% followed by ribs 28.0%, sternum 9.7% and pelvic bones 7.3%. Thoracic spine was found to be involved more (58.1%). Regarding patterns of metastatic lesions, 23 patients (74.1%) showed hot lesions, two patients (6.5%) showed cold lesions, four patients (12.9%) showed superscan and two patients (6.5%) showed pattern of hypertrophic osteoarthropathy. Bone metastasis was found in 75% cases of small cell lung carcinoma (SCLC) and 49.2% cases of non-small cell lung carcinoma (NSCLC). Among NSCLC, adenocarcinoma showed 62.9% metastases followed by 36.8% squamous cell carcinomas and 20.0% large cell carcinomas. In this series, clinical staging was done and 11 patients ( 18.6% ) were found in stage I, 21 patients ( 35.6% ) in stage II, 23 patients ( 39.0% ) in stage III and 04 patients ( 6.8 % ) in stage IV. Skeletal scintigraphy detected metastatic lesions in six of 11 cases (54.5 %) in clinical stage I, five of 21 cases (23.8 %) in clinical stage II, 16 of 23 cases (69.6 %) in clinical stage III and in all patients (100%) with clinical stages IV showing higher rate of bone metastases with advanced clinical stages.Conclusion: In this study, skeletal scintigraphy changed clinical staging of 27 patients. Early diagnosis of lung carcinoma, followed by bone scanning without delay helps to diagnose skeletal metastases, the presence of which is a major determinant in subsequent pathological staging and treatment planning.Bangladesh J.

Osteoporosis is a typical medical issue that overwhelmingly influences postmenopausal women. A bone density test is the only test that can diagnose osteoporosis before a broken bone occurs. The aims of this study was to find out the relationship between bone mineral density (BMD) and body mass index (BMI) in postmenopausal females. This cross sectional descriptive study was carried out in the Institute of Nuclear Medicine and Allied Sciences (INMAS), Sylhet. Study subjects comprised of 117 postmenopausal women between ages 45 to 85 years, with a mean age of 60.8 ± 9.2 years, who underwent BMD scan from January 2018 to June 2019. Duration of the study was 5 months ( march 2019 to august 2019). BMD was measured by the MedilinkMedix DR system. Findings of BMD of right femur showed osteopenia and osteoporosis (low BMD) in most of the women with under weight (81.0%) about one third (32.3%) of normal body weight and few (16.7%) of them over weight. Contrarily in left femur, low BMD was found in 08 (80.0%), 25 (40.3%) and 6 (16.7%) among underweight, normal, overweight patients respectively. According to BMI compare to the lumbar spine, low BMD was found in 48 (77.4%), 10 (100 %), 20 (55.6%), 03 (33.3%) among normal, underweight, overweight, and obese patients respectively. Relationship among BMD and BMI was found statistically significant in the both femurs (p < 0.001) and lumbar spine (p = 0.02). Low BMD was more severe in the 65-74 years’ age group in both femurs 65.4% and 65-85 years’ age group in lumbar spine 84.6% compare to other groups. The findings of this study reveal that low BMI and aging are associated with bone loss. Routine BMD checking in postmenopausal women might be important to initiate an early clinical intervention for osteoporosis. Bangladesh Med J. 2020 Sept; 49(3) : 22-28

Narrow gap III–V semiconductors have been investigated for semiconductor spintronics. By alloying these semiconductors with manganese magnetic semiconductors result. Large magnetoresistance (MR) effects have been observed in narrow gap magnetic semiconductor p–n heterojunctions. The MR which is positive is attributed to spin selective carrier scattering. For an InMnAs / InAs heterojunction a diode MR of 2680% is observed at room temperature and high magnetic fields. This work indicates that highly spin-polarized magnetic semiconductor heterojunctions can be realized that operate at room temperature. Devices based on the MR include spin diodes and bipolar magnetic junction transistors. We utilize the diode MR states to create a binary logic family.

Background & Objective: Hypothyroidism is a common endocrine disorder and requires lifelong treatment. The present study was designed to evaluate the impact of levothyroxine (LT4) on the oxidative stress and metabolic state by assessment of malondialdehyde (MDA) level along with lipid profile in hypothyroid patients. Methods: This cross-sectional analytical study was conducted in the Department of Pharmacology & Therapeutics, Rajshahi Medical College in collaboration with the Institute of Nuclear Medicine & Allied Sciences (INMAS), Rajshahi between July 2018 to June 2019 to compare malondialdehyde (MDA) level and lipid profile among hypothyroid patients, normal individuals and levothyroxine treated hypothyroid patients. The study included 20 newly-diagnosed hypothyroid patients, 20 Levo-treated hypothyroid patients and 20 healthy controls of both sexes. Result: The MDA level was significantly highest in newly diagnosed hypothyroid patients among the three groups (p < 0.001). The mean of MDA level of hypothyroid patients, LT4-treated hypothyroid patients and normal healthy controls were 10.0 ± 2.13 μmol/l, 5.88 ± 1.90 μmol/l and 2.66 ± 0.61 μmol/l respectively. Significantly higher values of total cholesterol (TC) (198.5 ± 19.2 mg/dl), triglycerides (TG) (147.0 ± 14.5 mg/dl), low density lipoprotein-cholesterol (LDL-C) (133.9 ± 19.7 mg/dl), and a significantly decreased value of high density lipoprotein-cholesterol (HDL-C) levels (35.1 ± 3.67 mg/dl) were observed in newly-diagnosed hypothyroid patients as compared to those in Levo-treated hypothyroid patients and normal healthy individuals (p = 0.009). Conclusion: The MDA level is significantly raised which suggests that people with hypothyroidism have high risk of free radical damage and risk of development of atherosclerosis, which may lead to coronary heart diseases (CHD). Treatment with LT4 significantly improves oxidative stress and corrects lipid profile but not up to the normal level. Addition of lipid lowering drugs and supplementation with antioxidants to traditional LT4 therapy can be tested to see further improvement in outcome parameters.

Objective: Endothelial dysfunction and atherosclerosis may be associated with subclinical hypothyroidism (SCH) in multiple ways. The intima-media thickness of the common carotid artery (CIMT) is an important parameter for early atherosclerotic change. Previously several studies addressed the association between SCH and CIMT. Some studies indicate that SCH might be related to increase CIMT, while other studies revealed no significant association. The aim of the study was to further examine the relationship between CIMT and SCH patients in our own laboratory setting in Bangladesh.Patients and Methods: This cross sectional study was carried out at the Institute of Nuclear Medicine and Allied Sciences (INMAS), Dhaka Medical College Hospital Campus, Dhaka during the period of January 2016 to October 2016. The study included 56 consecutive patients. Out of 56 patients, 26 were in SCH group and 30 were in euthyroid control group. CIMT was measured in each subject via High resolution B-mode ultrasonography. Data were analyzed between these two groups in respect to age, sex, BMI, and mean CIMT.Results: Out of 56 subjects, 26 were SCH group and 30 were euthyroid control group. Male to female ratio was 3:23 and 9:21 in SCH and control groups respectively. The mean age was 30±7.4 and 32±8.7 years in SCH and control groups respectively. The mean BMI was 25.6±4.7 kg/m2 in SCH and 25.1±4.1 kg/m2 in control group. The mean CIMT was significantly (p≤0.05) higher in SCH group (Right-0.80±0.05 mm, Left-0.80±0.07 mm) than control group (Right-0.60±0.05 mm, Left- 0.61±0.05 mm). SCH group was further subdivided into two groups with a cut off value of serum TSH at 10 mIU/L. The mean CIMT was significantly higher in SCH with TSH above 10 mIU/L than SCH group with TSH less than 10 mIU/L (p≤0.05). Pearson’s rank correlation test showed significant positive correlation between both CIMT and TSH values.Conclusion: Our study showed that CIMT was significantly higher in SCH group than euthyroid control group. The CIMT values were positively correlated with the TSH values. Therefore we may conclude that SCH is an independent risk factor for atherosclerosis in addition to other classical risk factors.Bangladesh J. Nuclear Med. 19(2): 123-127, July 2016

Objectives: The liver metabolizes thyroid hormones and thereby influences the regulation of their systematic endocrine effects. On the other hand, thyroid hormones play an important role in hepatic lipid homeostasis. Several studies addressed the association between thyroid function tests and non alcoholic fatty liver disease. The results of those studies indicate that hypothyroidism might be related to non alcoholic fatty liver disease. The recognized link between hypothyroidism and elements of metabolic syndrome may explain this relation. The present study was performed to evaluate the thyroid function status with the severity of sonographically suggested fatty liver subjects.Materials and Methods: This cross sectional study was carried out at the Institute of Nuclear Medicine and Allied Sciences (INMAS) of Dhaka Medical College Hospital Campus, Dhaka during the period of January 2014 to December 2014. A total number of 155 consecutive patients having sonographically detected fatty liver from the above mentioned hospitals were included in this study and they were divided into three grades depending on the sonographic criteria. Data were analyzed between these three grades in respect of age, sex, BMI, thyroid hormone levels (FT3, FT4 and TSH), fasting lipid profile and serum liver enzyme levels.Results: 82 (52.9%) patients had grade 1, 50 (32.3%) had grade 2 and 23 (14.8%) had grade 3 fatty liver. The mean age was found 39±10.9 years in Grade 1, 39.5±10.4 years in Grade 2 and 41.4±7.1 years in Grade 3. The difference was not statistically significant (p>0.05) among three groups. Male to female ratio was almost 2:3 in the whole study subjects. The mean BMI was significantly higher in grade 3 (p<0.05) followed by grade 2 and grade 1. 128 (82.6%) patients were euthyroid, 23 (14.8%) were subclinical hypothyroid and 4 (2.6%) were hypothyroid. In Anova test, the mean FT3 and FT4 were significantly declined (p<0.05) with increased grade but the mean TSH level was significantly increased (p=0.001) with increased grade of fatty liver. The Spearman’s rank correlation test shows that no significant but a negative correlation (r= -0.101; p=0.175) was found between FT3 and fatty liver of the study patients, but a significant negative correlation (r=-0.277; p=0.001) was observed between FT4 and fatty liver of the study patients. On the other hand a significant positive correlation (r=0.325; p=0.001) was observed between TSH and fatty liver of the study patients.Conclusion: In this study it has been found that thyroid hormone levels are significantly decreased with increasing grades of fatty liver detected by ultrasound. The underlying pathophysiology for this association is still not clear, however several mechanisms have been proposed. So the findings of this study will inspire other researchers to evaluate the thyroid function status with the severity of sonographically suggested fatty liver in larger scale.Bangladesh J.

InAs/InGaAsSb type-II superlattice structures (SLSs) were spontaneously formed by the molecular beam epitaxy of InAs/GaAs0.86Sb0.14 SLSs on InP substrates. The strain due to lattice mismatch between InAs and GaAs0.86Sb0.14 induced two exchange reactions of In–Ga and As–Sb at both InAs/GaAs0.86Sb0.14 heterointerfaces, resulting in the strain relaxation and the self-formation of InAs/InGaAsSb type-II SLS. By energy dispersive x-ray spectroscopy analysis, the mixed crystal composition of the InGaAsSb layer was determined to be approximately In0.8Ga0.2As0.9Sb0.1. Electroluminescence spectra of LEDs, including the self-formed InAs/In0.8Ga0.2As0.9Sb0.1 2.5-periodic SLS, showed double peaks of 2.6 and 3.2 µm at 15 K. The luminescence spectrum was based on two transition mechanisms of type-I transition in InAs and type-II transition between InAs and InGaAsSb. The experimental results of luminescence spectra were supported by theoretical calculations. The 3.3 µm emission was maintained above 220 K.
