Lesões intestinais decorrentes de isquemia e reperfusão: Fisiopatologia e modelos experimentais

The intestinal ischemia is unusual in vascular surgery emergency. Its main causes are embolisms and arterial thrombosis. In addition to severe ischemia, reperfusion of the ischemic tissues can lead to several complications that may worsen the ischemic lesion and produce a life threatening situation caused by systemic alterations. Intestinal tissue injuries due to ischemia and reperfusion have been demonstrated in clinical and experimental studies, in which pathophysiology and adequate treatment were also studied. The great variety of experimental models used and results achieved reflect the need for an intestinal ischemia and reperfusion experimental model that is simple, reproducible and consistent, in order to search for treatments that can reduce the damage caused by this situation. In this review, the main pathophysiologic aspects and the most used experimental models will be reviewed. Copyright © 2005 by Sociedade Brasileira de Angiologia e Cirurgia Vascular.

Lesões epiteliais malignas da conjuntiva e recidiva tumoral - Estudo retrospectivo

Purpose: To evaluate the conjunctival epithelial malign lesions carriers and the recurrence rate using exeresis and radiotherapy. Methods: A retrospective study was conducted observing 52 conjunctival epithelial malign lesions carriers treated from 1989 by 2003. The subjects were assessed to evaluation according: age, gender, time of start, classification of the lesion and recurrence rate. The lesion were surgically removed and radiotherapy was indicated when the exeresis was incomplete. Results: The majority of the patients were male, with 61 year old median age, white. The conjunctival squamous carcinoma was presented in 86,5% of the patients. The recidive rate was 11,5%, happened between 1 to 60 month postoperative. Conclusion: according our results the conjunctival epithelial malign lesions were more often observed in older, males and whites. The majority of the patient had conjunctival squamous carcinoma (86,5%). The recidive rate after exeresis and radiotherapy in patients with incomplete exéresis was 11,5%.

Estudo da imunopatogenia das lesões no sistema nervoso central de cães naturalmente acometidos por leishmaniose visceral

Visceral leishmaniasis in dogs is described as a chronic disease whose main symptoms are progressive weigth loss, cachexy and dermatologic lesions. Recently, the disease has been associated to neurologic disorders. A total of 40 dogs with visceral leishmaniasis were divided into two groups. The first composed of dogs without neurological signs (n=30) and the second by dogs with neurological disorders (n=10). Brain samples were collected, stored in 10% buffered formalin and subjected to immunohistochemical examination for amastigotes forms of Leishmania (Leishmania) infantum chagasi, CD3+, CD4+ and CD8+ T lymphocytes and macrophages. Imunnohistochemistry evaluation revealed no amastigote forms of the parasite. CD3+ T lymphocytes were present in 24/30 (80%) dogs without neurological signs and in all dogs from the second group (p=0.0011). CD4+ and CD8+ were rarely observed, with CD4+ immunostaining in 10/40 (25%) dogs, from which half of them had neurological disease (p=0.0090). The presence of CD8+ was detected only in 4/10 (40%) dogs from neurological group (p=0.0021). Macrophages were detected in 38/40 (95%) dogs, without significant differences between groups (p=0.7664).
