Hemorrhoids: an experimental model in monkeys
Plapler,HélioPURPOSE: Hemorrhoids are a matter of concern due to a painful outcome. We describe a simple, easy and reliable experimental model to produce hemorrhoids in monkeys. METHODS: 14 monkeys (Cebus apella) were used. After general anesthesia, hemorrhoids were induced by ligation of the inferior hemorrhoidal vein, which is very alike to humans. The vein was located through a perianal incision, dissected and ligated wi...

Larangeira,Lino Luis Sanches; Taha,Murched Omar; Ferme,Andréia; Lemos,Rodrigo; Plapler,HélioAs diversas técnicas para o tratamento cirúrgico da Síndrome do Intestino Curto apresentam, ainda hoje, problemas de difícil resolução. De todas, as mais promissoras são o transplante de intestino delgado e o transplante de colo. Uma técnica intermediária que mostrou resultados controversos tanto clínicos como experimentais, é a interposição de segmentos de colo no trajeto do intestino delgado após extensas res...
Peritoneal infection by Candida albicans: study of number and size of limphocyt...
Saad,Flávio; Silva,Maria Regina R. da; Hayashi,Hisakazu; Gompertz,Olga F; Segreto,Roberto de Araújo; Segreto,Helena Regina ComodoThe main purpose of this investigation was to stdy some aspects of leucocytes (granulocytes and limphocytes) and the phagocitic activity of peritoneal macrophages. In this experimen, which took place at Escola Paulista de Medicina - Universidade Federal de São Paulo - Brazil, it was used twenty female C57BLACK mice. Half of them were submitted to radiation to obtain immunossupressed animals (Group A - irradiate...
