Introduction: The detection of Trypanosoma cruzi in tissue samples is important in many situations, such as testing of the reactivation of the infection. The detection of T. cruzi nests in endomyocardial biopsies (EMB) may be useful to evaluate graft rejection. Given their scarcity, such nests are not routinely identified. To increase the diagnosis sensitivity, immunohistochemistry (IHC) may serve as a promisin...

Context - Clinical presentation of celiac disease is extremely variable and the diagnosis relies on serologic tests, mucosal intestinal biopsy and clinic and serologic response to a gluten-free diet. Objectives - To correlate the endoscopic and histological aspects of adult patients with suspicion of celiac disease and to evaluate the interobserver histological agreement. Method - Endoscopic aspects of 80 adult...
Bracken fern (genus Pteridium) has been shown to induce tumors in domestic and experimental animals. Epidemiological studies have also shown an association between human exposure to bracken toxins and increased risk for the development of upper gastrointestinal tract tumors. Our aim in this study was to investigate possible genomic alterations in bracken fern-induced tumors of experimental animals searching for...
The investigation of the importance of the genetics of Trypanosoma cruzi in determining the clinical course of Chagas disease will depend on precise characterisation of the parasites present in the tissue lesions. This can be adequately accomplished by the use of hypervariable nuclear markers such as microsatellites. However the unilocal nature of these loci and the scarcity of parasites in chronic lesions make...
Para avaliar se a intensidade da reação granulomatosa hepática induzida por ovos de S. mansoni tem relação com o metabolismo de drogas, camundongos foram infectados com 40 cercárias e testados quanto ao tempo de anestesia pelo pentobarbital sódico. Para diminuir a resposta inflamatória usou-se irradiação com 400 Rad ou azatioprina na dose de 20mg/kg, 3 vezes por semana, por 4 semanas, respectivamente no ou a pa...
Specimens from cervical dysplasias or carcinomas and genital condylomata acuminata were retrospectively analysed by in situ hybridization (ISH) with bioti-nylated DNA probes for human papillomavirus (HPV) types 6, 11, 16 and 18. In the control group no case was positive for HPV DNA. In mild/moderate dysplasias, 4 cases (14%) were positive for HPV 6 or 11 and 2 cases (7%), for HPV 16. In the severe dysplasia/in ...
