Texte intégralRésumé :
Background: Diabetes mellitus which is characterized by hyperglycemia is a metabolic disease due to insulin action, defects in insulin secretion, or both. Various studies have shown that herbs that have a hypoglycemic effect can be used in the treatment of diabetes mellitus. Generally, herbs can slow down the complications of diabetes mellitus and improve metabolism. The ability of plants to restore the function of pancreatic tissue to increase insulin production or make it easier for insulin to process glucose is related to the effects of hypoglycemia. Objective: Comparing plants that have a hypoglycemic activity that can be used in the treatment of diabetes mellitus in Indonesia. Methods: studying literature from various databases, websites, national journals, and relevant international journals to identify plants that have hypoglycemic activity. Results: The mechanism A. sativum as a hypoglycemic involves different fiber viscosities; A. vera involved as a hypoglycemic by protecting pancreatic? cells; Asiatic acid in C. asiatica increasing glycolysis by restoring the activity of key enzymes; G. max inhibiting ?-amylase and the stigmasterol increasing the absorption of blood glucose and reducing insulin resistance; P. macrocarpa exert their antidiabetic action via ?-glucosidase modulation, an extra distinctive pancreatic mechanism; S. arvensis has the potential to inhibit ?-amylase enzymes. Conclusions: This review article has presented 6 detailed comparisons of plants that have a hypoglycemic activity that can be used in the treatment of diabetes mellitus in Indonesia and we believe can be useful for students, researchers, or practitioners.
Keywords: Diabetes mellitus, hypoglycemia, Indonesian plants

Texte intégralRésumé :
This study aimed to ascertain the antioxidant and hypoglycemic activity of methanolic extracts of the leaves ofTerminalia arjuna, T. bellerica, andT. chebula. Extracts were evaluated for total phenolic, flavonoid, and tannin content, andin vitroantioxidant potential with DPPH, ORAC, and FRAP assays. The extracts' hypoglycemic activities were evaluated by hypoglycemic screening and an oral glucose tolerance test (OGTT) in normal rats. The methanolic extracts ofT. chebulaleaves exhibited the highest quantity of total phenolic and flavonoid content, followed by those ofT. bellericaandT. arjuna. T. arjunacontained more tannin thanT. bellericadid, but less than that ofT. chebula. The scavenging capacity ofT. chebulafor the antioxidant DPPH was the highest of the extracts tested, as it recorded the lowest IC50 value of all 3 extracts. Likewise, the results attributed theT. chebulaextract with the highest oxygen radical absorption capacity (ORAC). In the FRAP assay, the extracts' ferric reducing antioxidant abilities wereT. arjuna>T. chebula>T. bellerica. This correlates the potential of polyphenolic content enriched with antioxidant capabilities and substantiates the results of the hypoglycemic screening and OGTT, which determined that theT. chebulaextract had a better hypoglycemic effect in normal and glucose-induced hyperglycemic rats (p<0.001) than that ofT. bellericaandT. arjuna, respectively. The use of these Terminalia species as food supplements may help in reducing oxidative stress and related diabetic complications. The phytoconstituents responsible for the hypoglycemic activity need to be isolated to elucidate the relationship between the extracts' antioxidant capacity and their hypoglycemic effects.

Texte intégralRésumé :
The purpose of the present study was to examine the effect of blockade of N-methyl-d-aspartate (NMDA) receptors on the depolarization associated with severe hypoglycemia, which is commonly preceded by one or a few transient depolarizations reminiscent of cortical spreading depression (CSD). In the cerebral cortices of rats [K+]e and [Ca2 +]e were measured with ionselective microelectrodes. NMDA blockade was achieved by injection of MK801 in doses that block CSD. In control rats, the latency from the time point when blood glucose reached minimal levels to onset of ionic shifts was 33.2 ± 3.5 min, and [K+]e rose from 3.2 ± 0.2 to 55 ± 5 m M. All variables remained unchanged in rats treated with MK801. In another four rats treated with MK801, [Ca2+]e declined from 1.06 ± 0.22 to 0.12 ± 0.02 m M. Plasma glucose measurements indicated that the cortex depolarized at a plasma glucose concentration between 0.7 and 0.8 m M, i.e., within a narrow range, suggesting a threshold phenomenon. In conclusion, activation of NMDA receptors seems of minor importance for hypoglycemic depolarization. The ionic transients that precede the persistent hypoglycemic depolarization are probably mediated by mechanisms distinct from those of electrically induced CSD.

Texte intégralRésumé :
The ethanolic crude extract of Setaria italica seeds (Poaceae) was investigated for its possible anti-microbial, hypoglycemic and anti-diarrheal activities. Anti-microbial activity was evaluated by disc diffusion method while the hypoglycemic and anti-diarrheal properties were determined by oral glucose tolerance test and castor oil induced diarrheal method, respectively in Albino mice. The ethanolic extract and its different fractions of S. italica have shown good antimicrobial activity against gram negative bacteria having zone of inhibition 9-13 mm (ciprofloxacin: 40- 41 mm). In evaluation of hypoglycemic activity, ethanolic extract and its chloroform fraction, at 400 mg/kg, also showed promising hypoglycemic property having blood glucose level of 3.74 and 3.72 mmol/l after 120 minute, respectively when compared to standard glibenclamide (3.44 mmol/l). On the other hand, during the assessing for anti-diarrheal activity, the crude extract did not significantly reduce the frequency of defecation. The findings of the studies demonstrate anti-microbial and hypoglycemic properties of S. italica.Dhaka Univ. J. Pharm. Sci. 15(1): 31-35, 2016 (June)

Texte intégralRésumé :
Abstract: Various extracts of diverse parts of medicinal plants have been shown to possess antidiabetic and hypoglycemic effect. Most of them look to act directly on pancreas (pancreatic effect) and stimulate insulin level in blood. Some have extra pancreatic effect by acting directly on tissues like liver, muscle, etc and alter favorably, the activities of the regulatory enzymes of glycolysis, gluconeogenesis and other pathways. The research work embodied in the thesis deals with the scientific exploration of indigenous plants viz., Ficus bengalensis Linn for their possible anti-diabetic and hypoglycemic activity. The present investigations concluded that the ethanolic and aqueous extracts of aerial parts of Ficus bengalensis Linn endowed with potential antidiabetic activity which could be attributed by their possible multiple effects on both pancreatic and extra-pancreatic site by influencing either the metabolism and/or absorption of glucose, which in turn also influence the lipid metabolism.

Texte intégralRésumé :
The emergence and spread of antimalarial drug resistance of Plasmodium parasites, as well as hypoglycemia, during malaria infection, and subsequent death, are critical problems in malaria-endemic areas. Hence, finding new compounds, especially plant extracts having antimalarial and anti-hypoglycemic activities, are urgently needed. The present study aimed to investigate the antimalarial and anti-hypoglycemic effects of Moringa oleifera leaf extract in Plasmodium berghei infection in mice. Aqueous crude extract of M. oleifera leaves was freshly prepared and used for an efficacy test in vivo. Groups of ICR mice (5 mice in each) were infected with 1´107 infected red blood cells of P. berghei ANKA by intraperitoneal injection and given the extract orally with doses of 100, 500, and 1000 mg/kg for 4 consecutive days. Parasitemia and plasma glucose levels were subsequently measured. The results showed that M. oleifera leaf extract presented significant (p < 0.001) inhibition of parasitemia in a dose-dependent manner. Moreover, this extract exerted anti-hypoglycemia effects in infected mice in a dose-dependent manner. The highest degrees of activity were found at a dose of 1000 mg/kg of the extract. Additionally, no effect on plasma glucose was found in normal mice treated with this extract. It can be concluded that aqueous crude extract of M. oleifera leaves exerted antimalarial and anti-hypoglycemic effects in P. berghei infection in mice.

Journal of Pharmacy & ; Pharmacognosy Research 8, no 1 (1 janvier 2020) : 569–79. http://dx.doi.org/10.56499/jppres20.911_8.6.569.
Texte intégralRésumé :
Context: The use of animal models is a longstanding practice in biological research. Among different models, the mouse is the most widely used and accepted model. In designing the mouse model, a male mouse is generally preferred over a female to avoid the effect of changing hormonal state in females. However, it is not known whether mouse sex affects all experiments. Aims: To determine the effect of mouse sex on pharmacological responses in antinociceptive, antipyretic, hypoglycemia, hepatoprotective and antidiarrheal experiments. Methods: Antinociceptive study was performed by three different experiments. An antipyretic experiment was performed by yeast induced hyperthermia test. The effect on hypoglycemic response was assessed by an oral glucose tolerance test. The effect on the hepatoprotective study was evaluated by carbon tetrachloride-induced liver damage. The antidiarrheal study was conducted by a castor oil-induced diarrhea test. Results: Antinociceptive studies demonstrated mixed effects. Hot plate test showed significant differences; the licking test showed variation only in the late phase, while no significant variation was observed. In the antipyretic experiment, female mice showed higher body temperature in both control and standard that varied significantly with male mice. Hypoglycemia and hepatoprotective tests did not show significant variation between sexes; however, liver enzymes levels were found higher in males while the percentage liver weight was higher in females. In the antidiarrheal test, the male mouse was observed to have higher responses than the female. Conclusions: Antinociceptive and antipyretic investigations should be performed separately on both male and female mice. On the other hand, hypoglycemic, hepatoprotective and antidiarrheal tests can be conducted on any mouse sex, and findings on particular sex can be extrapolated to the opposite sex.

Texte intégralRésumé :
The aim of this study was to provide a practical experimental basis for the development of Neocryptotanshinone (NCTS) as an effective hypoglycemic drug and a theoretical method for the rapid screening of natural compounds with hypoglycemic effects. Molecular docking was used to screen the most suitable ligand. Hematoxylin and eosin, immunohistochemical staining, enzyme-linked immunosorbent assay and Western Blotting approved the hypoglycemic effect of NCTS. According to the free energy of binding, among 180 active compounds from the Traditional Chinese Medicine Integrated Database, NCTS was finally chose for investigation its hypoglycemic effects. In db/db mice, NCTS significantly reduced body weight and plasma glucose, improved glucose tolerance and levels of fasting plasma glucose and glycated hemoglobin A1c, and decreased insulin resistance after six-week administration. NCTS restored the pathological state in the liver of db/db mice and significantly decreased protein tyrosine phosphatase 1B (PTP1B) expression in the liver and muscle of db/db mice, which is related to the regulatory effect of NCTS on insulin receptor substrate 1. In conclusion, we successfully explored the hypoglycemic effect of NCTS in db/db mice via regulating the expression of PTP1B.

Texte intégralRésumé :
The rate of accumulation of malonic dialdehyde was increased, the activities of superoxide dismutase, NADP-dependent glucose- 6-phosphate, malate, isocitrate dehydrogenases and glutathione reductase decreased, and the levels of diene conjugates decreased in the hemispheres and brain stem of rats subjected to 7-9 hypoglycemic comas. The activities of neutral and acid proteases were increased in the stem structures. The detected changes indicate an oxidative stress developing in the nerve tissue after repeated hypoglycemic exposures. Such changes appear after glucose arrest of hypoglycemic coma and can be important in the pathogenesis of posthypoglycemic encephalopathy.

Material e MÃtodos: Ratos Wistar, machos, foram tratados por via oral com a FSM (50 e 100 mg/kg), glibenclamida(GLI, 5 mg/kg), Ãgua destilada ou glicose), e o sangue coletado antes e 30, 60, 90 e 120 min apÃs à glicose (3g/kg) para medir a hipoglicemia. Na avaliaÃÃo da glicemia em ratos normais, os animais foram tratados com a FSM (100 mg/kg), GLI (5 mg/kg) ou Ãgua destilada e a glicemia medida antes e 5 dias depois do tratamento. O diabetes foi induzidos com aloxano (40 mg/kg, i.v) e apÃs 48 h, os animais foram tratados por via oral com a FSM (100 mg/kg), GLI (5 mg/kg) e TIR (2 e 4 mg/kg) e a glicemia determinada antes e 30, 60, 90 e 120 min apÃs à glicose. Outros grupos de animais diabÃticos foram tratados com a FSM (50 e 100 mg/kg), FRT (100 mg/kg), TIR (1- 4 mg/kg), GLI (2,5 e 5 mg/kg), MET (50 e 100 mg/kg) e 5 dias depois, o sangue foi coletado para avaliaÃÃo da glicemia, triglicerÃdios, VLDL, colesterol total, HDL, AST, ALT, urÃia e creatinina. Os animais que sobreviveram foram sacrificados, dissecados o pÃncreas e o fÃgado, e os ÃrgÃos foram usados para a avaliaÃÃo histopatolÃgica, sendo este Ãltimo tambÃm utilizado para avaliaÃÃo da atividade antioxidante (TBARS, GSH, catalase e nitritos/nitratos). Para determinaÃÃo da hemoglobina glicada in vitro foi utilizado sangue de ratos nÃo-diabÃticos incubados com D-glicose (50mM) e FSM ou TIR (50 g/ml). Na dosagem do glicogÃnio hepÃtico, ratos diabÃticos foram tratados por 10 dias com a FSM. A avaliaÃÃo da atividade analgÃsica foi realizada em camundongos Swiss, machos, tratados com a FSM (50 e 100 mg/kg, v.o.), TIR (1,2 e 4 mg/kg), GLI ( 5 mg/kg) e MOR (10 mg/kg,.) no teste da formalina. A atividade antiinflamatÃria foi analisada com os modelos do edema de pata induzido por carragenina ou dextrano, em ratos e camundongos tratados com FSM (50 e 100 e 200 mg/kg), TIR (1- 4 mg/kg), GLI ( 5 mg/kg), INDO (5 mg/kg) e CIPRO (5 e 10 mg/kg,v.o.). Resultados: A FSM demonstrou pequena atividade hipoglicemiante no teste de tolerÃncia a glicose em ratos normais e foi ineficaz em diabÃticos. A FSM reduziu a glicemia em ratos normais, enquanto a TIR nÃo teve efeito. O tratamento de ratos diabÃticos durante 5 dias com a FSM, FRT, TIR, GLI e MET reduziu a glicemia, triglicerÃdios, VLDL, urÃia e creatinina. Nenhuma potencializaÃÃo do efeito hipoglicÃmico foi observado com a associaÃÃo de FSM + TIR ou GLI + TIR. Os estudos histopatolÃgicos mostraram regeneraÃÃo das lesÃes e aumento do nÃmero de cÃlulas apÃs tratamento dos animais diabÃticos com a FSM, TIR e GLI. A FSM e TIR mostraram atividade antioxiodante, como aumento no nÃvel de GSH e reduÃÃo nos nÃveis de catalase e nitritos. A FRT aumentou somente o GSH. A FSM e TIR reduziram a hemoglobina glicada, demonstraram potente atividade analgÃsica, mas foram ineficazes como antiinflamatÃrias. A FSM e TIR nÃo reverteram a hiperglicemia induzida pelo diazÃxido, um bloqueador dos canais de potÃssio. MET e TIR reduziram a glicemia, triglicerÃdios, VLDL, urÃia e creatinina, e os efeitos hipoglicemiantes foram potencializados quando essas duas drogas foram associadas. ConclusÃo: Estes resultados confirmam a atividade hipoglicemiante da FSM. O mecanismo de aÃÃo nÃo parece ser similar aquele apresentado pelas sulfonilurÃias. A potencializaÃÃo do efeito hipoglicemiante da TIR foi observada apÃs sua associaÃÃo com MET, sugerindo que o mecanismo de aÃÃo dos constituintes hipoglicÃmicos de C. verticillata à similar ao das biguanidas. Posteriormente, a FSM e TIR apresentaram atividade antioxidante, reduzidos nÃveis de hemoglobina glicada, aumento do glicogÃnio hepÃtico, e no nÃmero de cÃlulas pancreÃticas, sugerindo que essas drogas diminuem a toxicidade hepÃtica e pancreÃtica. Embora a atividade antiinflamatÃria tenha sido marginal, seu efeito foi potencializado pela associaÃÃo com TIR, indicando que a TIR à um dos principais constituintes bioativos de Cissus verticillata.

Insulin resistance, the impaired sensitivity of tissues to insulin, is a causative factor for type 2 diabetes. Whereas the occurrence of insulin resistance is closely related to inflammation induced by cytokines such as TNF-α (tumor necrosis factor-α). Thus, anti-inflammation is suggested to be a strategy for treating and preventing insulin resistance and type 2 diabetes. Previously, fractions isolated from the crude extract of Cucurbita moschata were found to have hypoglycemic activities in diabetic mice. Eleven natural products were purified from these fractions. To obtain more insights about the hypoglycemic effect and mechanism of C. moschata, this study aimed to characterize the hypoglycemic effects and anti-inflammatory activities of these natural products. Among the eleven compounds, three of them, namely syringaresinol (NH40), ferulin acid (NH65) and (22E,24R)-24-methyl-6β-methoxy-5α-cholesta-7,22-diene-3β,5-diol (NH76) were found to increase glucose uptake of insulin-resistant cells in the presence of insulin, indicating an insulin sensitizer activity. Meanwhile, NH76 and 3β-hydroxy-(22E,24R)-ergosta-5,8,22-trien-7-one (NH86) could increase glucose uptake of normal cells and activate AMP-activated protein kinase, suggesting an insulin-like activity. NH65 and 4-ketopinoresinol (NH63) diminished TNF-α-induced expression of inducible nitric oxide synthase, implying an anti-inflammatory activity. Further investigation suggested that NH65 and NH40 activated the insulin signaling pathway in insulin-resistant cells. Meanwhile, NH76 was confirmed to activate the insulin signaling pathway in both normal cells and insulin-resistant cells. In conclusion, natural products from C. moschata exhibited multiple functions, including insulin-like, insulin sensitizer, and anti-inflammatory activities. These activities likely contribute to the hypoglycemic effect of C. moschata.

Texte intégralRésumé :
The antimicrobial effect of essential oils and their main constituents, the terpenoids, has been generally reviewed in this article, with a comparative investigation of the structure-activity relationship. Terpenoids are widespread metabolites in plants belonging to different chemical classes, whereas oxygenated derivatives constitute the predominates. They could be classified as diterpenes, triterpenes, tetraterpenes, or hemiterpenes and sesquiterpenes. As crude materials, terpenoids are also broadly utilized in drug, food, and beauty care product ventures. Terpenoids have antitumor, anti-inflammatory, antibacterial, antiviral, antimalarial effects, promote transdermal absorption, prevent and treat cardiovascular diseases, and hypoglycemic activities. Moreover, terpenoids have many critical uses as insecticides, immunoregulators, antioxidants, antiaging, and neuroprotection agents. Terpenoids have a complicated construction with assorted impacts and various components of activity. Using plants – containing – terpenoids as neutraceuticals in the nutrition of humans and animals also constitutes a potential issue as natural inhibitors for microbes. These phytochemicals are generally conveyed in soil products and are particularly helpful in food protection as microbial development inhibitors.

Texte intégralRésumé :
Semecarpus anacardium is classified in Ayurveda under the category of toxic plants. However, this toxic plant is reported to possess anti-inflammatory activity, anti-arthritic effect, antioxidant activity, antimicrobial activity, anti- carcinogenic activity, hypoglycemic activity, cardioprotective, hepatoprotective, neuroprotective, and hypolipidemic activity etc. All these activities are attributed to its various constituents like phenolic compounds, flavonoids, carbohydrates, alkaloids, steroids, etc. In Ayurveda, a series of pharmaceutical procedures which converts a poisonous drug into a safe and therapeutically effective medicine is termed as Shodhana. Shodhana improves the yield, decreases the phenolic and flavonoid content; and converts toxic urushiol into nontoxic anacardol derivative thereby reducing toxicity of nuts of Semecarpus anacardium. There are reports of alteration in pharmacology and phytochemistry of nuts of Semecarpus anacardium due to Shodhana.

Texte intégralRésumé :
This study is achieved and published under the aegis of the National University of Physical Education and Sports of Bucharest, as a partner in the program co-financed by the European Social Fund through the Sectoral Operational Programme for Human Resources Development 2007-2013, developed through the project Pluri- and interdisciplinary in doctoral and post-doctoral programmes, Project Code: POSDRU/159/1.5/S/141086, its main beneficiary being the Research Institute for Quality of Life, Romanian Academy. Our contribution to the project development is based on a research topic oriented towards the possibilities of interdisciplinary intervention on the diabetic child, in the context of the permanent concerns of the diabetes care team to keep under control the evolution of this diagnosis. The objective of the present paper is to highlight the opportunity for the child with type 1 mellitus diabetes of using the continuous glycemic monitoring system (CGMS) also during the development of physical education programmes, not only in domestic and school activities, as a support tool for adjusting the effort parameters and reducing the risk of hypoglycemia. The research took place within the Bucharest National University of Physical Education and Sports, in cooperation with the Bucharest DiabNutriMed Clinic of Diabetes, in the period between October and December 2014. As research methods, we used: bibliographic study, observation, computerized devices for continuous glycemic monitoring- DEXCOM G4 Platinum and also the case study. In this paper, we present the case of a diabetic child aged 6 years, who was diagnosed with this metabolic disease at 2 years and 6 months and who has been benefiting of a CGMS for about 2 years. His involvement in physical exercise programmes is put under the sign of the major risk of hypoglycemia, given the pronounced tendency of his body to have low glycemic values. The advantage of the electronic device he permanently carries, regardless of the type of activity performed, must also be emphasized in the case of his participation in motor activities, the more so as physical effort is a blood glucose-consumer. CGMS allows the teacher to find the initial, intermediate and final glycemic values without using the glucometer under conditions of precarious hygiene. Then, depending on the glycemic value displayed on the device screen during practice, the teacher chooses the physical exercises and establishes the effort dosing. In this way, the glycemic value that threatens the child's functional state is identified and the administration of carbohydrates in due time is facilitated, by reducing the risk of hypoglycemia and preventing the hypoglycemic coma. In conclusion, we appreciate as efficient the utilization of continuous glycemic monitoring systems in the case of physical exercise performed by the child with type 1 mellitus diabetes and we encourage the specialists in physical education and sports to get involved without reticence into the development of motor activities with this category of population.

Texte intégralRésumé :
Proteins derived from lupin seeds are gaining attention as a source of bioactive peptides. In fact, several pieces of evidence highlight the biological activities of lupin protein hydrolysates and peptides, including hypocholesterolemic, hypoglycemic, antimicrobial, anti-inflammatory, and immunomodulatory effects. The health-promoting activities of lupin peptides have been tested in different animal models and clinical trials. Briefly, diets containing protein from L. albus or L. angustifolius significantly reduce both total cholesterol and low-density lipoprotein (LDL) cholesterol (LDL-C) levels versus control diets containing casein in a rat or hamster models of hypercholesterolemia. An uncontrolled clinical trial on L. albus and two controlled ones on L. angustifolius have confirmed the hypocholesterolemic activity in humans. In light with these evidences and with a more updated perception of the phenomenon, our study suggests that the observed health-promoting activity does not lie in the native protein, but the mixture of peptides generated from the physiological hydrolysis of proteins during digestion. Indeed, many efforts have been pursued in order to characterize the molecular mechanism through which lupin hydrolysates, obtained different hydrolytic enzymes, exert hypocholesterolemic and anti-diabetic effects in vitro and in vivo. In this context, specific peptides responsible of the biological activity exerted by the peptide mixture were also identified and fully characterized from chemical and biological point of view. Doubtless, our results highlight that lupin hydrolysates may be exploited as new ingredients for the development of dietary supplements or functional foods

This paper is a case study that highlights our concern for increasing the quality of life of the child with diabetes, using telemedicine devices. The central objective is to emphasize the efficiency of the Omnipod wireless insulin pump in the case of a child who, together with the diabetes care team, appropriately manages this metabolic disease and whose treatment also includes physical exercise. Our interest is oriented towards proving the effects derived from the practice of physical exercises on decreasing the amount of insulin administered during the days when the child participates in motor activities, through computerized monitoring. The research was conducted at the Bucharest DiabNutriMed Clinic of Diabetes, from September to November 2015. As research methods, we used: bibliographic study, observation, case study. Data were collected using the computerized DEXCOM Platinum G4 continuous glucose monitoring devices, the Omnipod wireless insulin pump and their related software programs, and the Diasend platform for downloading the data. We present the case of a child with diabetes who has been using a wireless insulin pump since June 2015. We mention that this child is included in the target group of the project sponsored by Vodafone, "Telemedicine and the insulin-dependent child", obtained by the DiabNutriMed Clinic,which aims to introduce advanced technology, with sensors for continuous glucose monitoring, 24hours a day, which eliminates the need for daily injections to measure the glucose levels. During our study, the child participated regularly in physical exercise programs, three times a week, outside the school schedule, practicing activities such as swimming and dynamic games. Information about the child's glucose level and its evolution trend was sent to a web platform and visualized in real time by the family and the diabetes physician, who provided guidance on treatment. According to the indications, the family could remotely administer insulin using the wireless insulin pump with remote control, while the child was carrying out educational and recreational activities uninterruptedly. It was found that, during the days of participation in motor activities, the amount of insulin decreased, its administration being even suspended when the child showed a tendency towards persistent hypoglycemia, which is impossible to achieve in the insulin therapy administered with an insulin pen, where, once administered, insulin cannot be stopped any more over its entire duration of action, 4 to 6 hours (for rapid insulin). Recording these beneficial effects of physical exercises on the child with diabetes entitles us to state that the Omnipod wireless insulin pump represents not only an instrument for insulin administration, but also a possibility of individualized management adaptable to the activities of the child from minute to minute, which allows him/her free access to various activities. In conclusion, we consider as efficient the use of telemedicine devices for the child with diabetes, because it facilitates a good control of this disease and brings more hope in his life.
