Legítima representante do rol de doenças tropicais negligenciadas, a esquistossomose causada pelos trematódeos do gênero Schistosoma spp. constitui uma enfermidade endêmica em 78 países, impondo grandes desafios à saúde das populações afetadas. Atualmente, a ausência de uma vacina eficaz reforça o papel da quimioterapia como o pilar do controle da morbidade e transmissão, a qual permanece restrita e ameaçada pela eminência de cepas resistentes ao praziquantel. Nos últimos anos, esforços vêm sendo empreendidos na tentativa de descobrir novos fármacos esquistossomicidas, com notável contribuição dos produtos naturais. Neste contexto, o flavonóide Licochalcona A - marcador quimiotaxonômico da espécie Glycyrrhiza inflata – que detém atividades biológicas diversas, como anti-inflamatória, antioxidante e antiprotozoária para espécies de Leishmania spp. e Plasmodium spp., demonstrou atividade esquistossomicida promissora em um estudo preliminar, sendo considerado o objeto do presente estudo. Desta forma, a proposta foi avaliar a progressão da esquistossomose mansônica em camundongos Swiss frente ao tratamento com LicoA, além de obter mais informações acerca de sua atividade contra vermes adultos in vitro. Após um período de 24 horas de incubação, a LicoA a partir de 50µM foi capaz de causar o escurecimento do tegumento dos vermes, a perda moderada da motilidade e áreas de intumescimento corporal. Além disso, produziu pontos de retenção do corante resorufin e consequentemente, a descontinuidade na marcação dos principais túbulos e ramos do sistema excretor dos esquistossomos. Este último pode ser a origem dos demais efeitos, contribuindo para o entendimento das potenciais influências da droga sobre receptores e/ou enzimas presentes nos esquistossomos. Além disso, a suposta inibição parcial das SmATPDases pode igualmente contribuir para o insucesso do parasitismo. Nos ensaios in vivo, o esquema de 50mg/Kg em duas doses administrado por via intraperitoneal foi o mais promissor, alcançado uma mediana de 25% da redução da carga parasitária e o maior deslocamento hepático dos vermes. Por outro lado, a droga não induziu alterações no oograma qualitativo ou no peso hepático e esplênico, mostrando relativa inércia sobre a cinética de oviposição. Mais estudos devem ser conduzidos para acumular evidências sobre o efeito esquistossomicida da Licochalcona A, principalmente os que contemplem um maior número de animais e de parâmetros analisados, como por exemplo, o perfil de citocinas e quimiocinas in vivo, além de outras metodologias in vitro e o aprimoramento daquelas que foram aqui empregadas, de modo a fornecer mais detalhes sobre a influência da LicoA em alguns sistemas intrínsecos ao parasito.
Schistosomiasis, one significant neglected tropical disease, is an infection caused by trematode worms of the genus Schistosoma spp. it is endemic in 78 countries, being a major public health challenge. Currently, the absence of an effective vaccine supports the chemotherapy as the mainstay of schistosomiasis control programs. However, the chemotherapy has limitations, such as, the emergence of praziquantel-resistant strains. In recent years, attempts to discover new antischistosomal drugs had remarkable contribution of natural products. In this context, the flavonoid Licochalcona A - chemotaxonomic marker of the specie Glycyrrhiza inflata - has several biological activities such as anti-inflammatory, antioxidant and anti-protozoan against species of Leishmania spp. and Plasmodium spp. Moreover, Licochalcona A showed promising schistosomicidal activity in a preliminary study. Thus, the aim of this study was to evaluate the progression of schistosomiasis in Swiss mice treated with LicoA and it activity against adult worms in vitro. After 24 hour incubation, concentrations from 50μM LicoA caused tegument darkening, moderate loss of motility and areas of swelling body. Moreover, the exposure to the compound produced accumulation of resorufin and hence the discontinuity in the labelling of the main branches and tubules in the excretory system of schistosomes. The latter may be the source of other effects, contributing to the understanding of the potential influence of the drug on receptors and / or enzymes in schistosomes. In addition, the alleged partial inhibition of SmATPDases can also contribute to the failure of parasitism. In vivo tests, the 50 mg/kg schedule of two doses administered intraperitoneally were the most promising reached a median 25% reduction of worm burden and increased hepatic displacement of the worms. Moreover, the drug did not induce changes in the qualitative or oogram liver and spleen weight relative inertia about showing the kinetics of oviposition. Further studies should be conducted to collect evidence on the effect of schistosomicidal Licochalcona A, especially those that consider a larger number of animals and analyzed parameters, such as the profile of in vivo cytokines and chemokines, and other in vitro methods and the improvement of those who were employed here in order to provide more details on the influence of LicoA in some systems intrinsic to the parasite.

A dacriocistografia convencional (DCG) é a técnica de imagem mais utilizada para a avaliação do sistema lacrimal excretor. Recentemente, DCG por ressonância magnética (DCG-RM) e por tomografia computadorizada (DCG-TC) têm sido empregadas em pacientes humanos. No entanto, em cães, os relatos de investigações sobre estas técnicas são escassos. Os objetivos, com este estudo, foram: o desenvolvimento de protocolos de RM e TC; a comparação destas técnicas para avaliação do sistema lacrimal excretar; a avaliação biométrica do ducto nasolacrimal e a apresentação da utilidade de ferramentas de reconstrução tridimensional para a visibilização do sistema lacrimal excretor em cães. Material e Métodos: DCG-RM e DCG-CT foram realizadas bilateralmente em 32 cadáveres de cães. Após canulado, o canalículo superior foi preenchido com meio de contraste (contraste iodado puro e gadolinio 1:200, para CT e RM respectivamente). Imagens transversais e tridimensionais de TC foram obtidas utilizando-se cortes de 0,8mm e 2mm de espessura. O protocolo de RM incluiu as sequências T1W/3D/FFE, T1WfTSE e PDW/TSE. Em ambas as técnicas, foram testadas as orientações perpendicular e obliqua dos cortes. Os diâmetros transversais e longitidinais e o comprimento dos ductos nasolacrimais de 23 cães foram mensurados bilateralmente. Resultados: no exame de DCG-TC, todos os componentes foram visibilizados de modo satisfatório na grande maioria dos animais. O exame de DCG-RM apresentou tempo de varredura mais longo, obtendo-se melhores resultados com a seqüência T1W/3D/FFE. As médias dos diâmetros transversais para os grupos de peso corporal 1, 2 e 3 nas três regiões avaliadas variaram entre 1,07mm e 1,09mm. As médias dos diâmetros longitudinais para as classes 1, 2 e 3 nas três regiões...
Conventional radiographic cannulation dacryocystography is the most commonly used technique for evaluallon of the nasolacrimal system. Recently, MR-DCG and CT¬DCG have been extensively employed in humans patients. Systemafic investigations of these techniques in dogs are not frequently observed in medicai literature. The objectives of this study are: 1, development of MR-DCG and CT-DCG protocols and the comparison between these techniques for the evaluation of the nasolacrimal system in dogs and 2, biometric evaluation of the nasolacrimal duct and to test the usefulness of 3D reconstruction techniques for visualization of this system in dogs. Material and Methods: MR-DCG and CT-DCG were bilaterally performed in 32 cadavers of dogs. The superior lacrimal canaliculi was canulated and contrast media injected (Imerone and Omniscan® 1:200, for CT and MR respectively). CT transverse and 3D images were obtained using 0.8 to 2mm-thick slices. MR protocol included transverse images obtained by T1W/3D/FFE, T1WfTSE and PDW/TSE sequences. For both techniques, two sfice orientations were tested: perpendicular and oblique to the hard palate. Transverse and longitudinal diameters and total length of the nasolacrimal ducts of 23 dogs were bilaterally obtained. Results: in CT scans, ali the structures could be well visualized in great majority of the dogs. MR images required longer scan time. Sequence T1W/3D/FFE offered beber results when compared to PDWTTSE and T1WTTSE. The mean longitudinal diameter of the nasolacrimal duct in weight classes 1, 2 and 3 in ali regions ranged between 1,07mm e 1,09mm. The mean transversal diameter of the nasolacrimal duct in weight classes 1, 2 and 3 in ali regions ranged between 1,34mm e 3,31 mm. The mean length of the nasolacrimal duct in weight classes 1, 2 and 3 were respecfively 70mm, 93,55mm... (Complete abstract click electronic access below)

O mecanismo de drenagem lacrimal do cão não é totalmente conhecido. O objetivo deste estudo foi avaliar a via lacrimal excretora do cão normal do ponto de vista histológico, na tentativa de melhor conhecer esta estrutura. Método: realizou-se um estudo envolvendo 30 cães normais (60 olhos), sem raça definida, adultos, pesando de 4,15 a 30 kg. Esses animais foram submetidos a exame ectoscópico (exame externo), dacriocistográfico e avaliação histológica da via lacrimal excretora. Resultados: a via lacrimal excretora do cão é formada por pontos, canalículos e saco lacrimal, e ducto nasolacrimal, o qual se abre no meato inferior da narina, observados ao exame dacriocistográfico. Histologicamente, a via lacrimal excretora do cão é, em parte, revestida por epitélio escamoso estratificado não queratinizado, o qual repousa em estroma de tecido conjuntivo denso; e, em parte, revestida por epitélio estratificado colunar, repousando em estroma de tecido conjuntivo frouxo. As regiões do saco lacrimal e do ducto nasolacrimal são circundadas por rica rede vascular. Não foram evidenciadas fibras musculares circundando (intimamente dispostas) a via lacrimal excretora do cão, ou justapostas a essa via. Conclusão: o cão não possui estruturas contráteis envolvendo intimamente a via lacrimal excretora, podendo-se supor que o mecanismo de drenagem lacrimal não envolva mecanismos de contração muscular.
The mechanism of lacrimal drainage system in dogs is not still completely understood. The aim of this study was to evaluate the histological aspects of lacrimal drainage system in the healthy dog, trying to know better this anatomical structure. Method: thirty healthy adult cross-bred dogs (sixty eyes), weighting from 4.1 to 30 kg were used in this study. These animals were submited to an extern ophthalmic examination, dacryocystorhinography and a histological analysis of lacrimal drainage route. Results: the lacrimal drainage system is composed by points, lacrimal canaliculi, lacrimal sac and nasolacrimal duct. As showed at the dacryocystorhinography, the nasolacrimal duct opens towards to the meato inferior da narina. By the histological analysis, the lacrimal drainage route is partially composed by non-keratinized stratified squamous epithelium which lies on dense conjunctive tissue stroma, and partially covered by stratified columnar epithelium over a layer of cells of loose conjunctive tissue stroma. The lacrimal sac and nasolacrimal duct areas are rounded by a well developed blood vessels net. It were not observed muscle fibers rounding, or nearby, the lacrimal drainage route. Conclusion: contractile structures rounding lacrimal drainage route were not observed in the dog. We supposed that the mecanism of lacrimal drainage is not related to a muscle contractile responses.
