Abstract: background: to study, experimentally, the reduction of intestinal transit through artificial pylorus in terminal ileum of rats, without sectioning the enteric muscles. methods: the study was carried out in two groups of 20 rats each. four pylori were made in the terminal ileum of each animal with sero-muscular stitches circumferentially spread around the intestinal loop. group 1 rats were killed after 15 days and those from group 2 after 30 days. the intestinal circumference was measured during surgery and post-mortem. results: group 1 showed a mean 3mm dilatation in the first pylorum and 4.15mm in the fourth one. in group 2 the mean dilatation was 7.50 mm in the first pylorum and 5.75mm in the fourth one. the presence of the well defined formation of the pylori were evident from anatomical studies. conclusion: it is thus not necessary to remove or section the small intestine muscles nor section the intestinal neural plexus to promote intestinal dilatation and reduce intestinal transit with this method.

Abstract: OBJETIVO: verificar a viabilidade do transplante autógeno de testículos na parede abdominal e omento, em ratos, sem anastomose vascular, analisando a estrutura histológica das células testiculares após o implante. MéTODOS: foram utilizados 60 ratos Wistar, machos, de 10-12 semanas de idade, distribuídos em três grupos: grupo controle: 20 ratos sem orquiectomia, com opera o simulada; grupo 2: 20 ratos com orquiectomia bilateral sendo um testículo implantado no omento maior; grupo 3: 20 ratos com orquiectomia bilateral, sendo um testículo implantado na parede abdominal. Após dois meses eles foram mortos e os testículos avaliados pelo exame anatomopatológico. RESULTADO: o peso dos implantes teve perda de 0,62g no grupo 2, de 0,73g no grupo 3 e no grupo controle houve aumento de 0,1g. Ao estudo anatomopatológico, no grupo controle a estrutura testicular foi preservada; no grupo 2 encontrou-se 80% de inflama o e necrose, n o foram visualizadas células de Sertoli ou de Leydig, em dois animais encontraram-se túbulos seminíferos; no grupo 3 encontrou-se 75% de inflama o e 60% de necrose, somente em um conseguiu-se visualizar células de Sertoli e em três células de Leydig. CONCLUS O: n o é viável o transplante autógeno de testículo sem anastomose vascular em ratos no omento maior e na parede abdominal. OBJECTIVE: To verify the feasibility of autologous transplantation of testes to the abdominal wall and omentum of rats without vascular anastomosis, analyzing the histological structure of the testicular cells after implantation. METHODS: We used 60 male Wistar rats, 10-12 weeks of age, which were divided into three groups: control group: 20 rats without orchiectomy with sham operation; group 2: 20 rats undergoing bilateral orchiectomy, with one of the testicles being implanted into the greater omentum; and group 3: 20 rats submitted to bilateral orchiectomy, with one testicle implanted in the abdominal wall. After two months they were euthanized and the testes evaluated by histopathology. RESULTS: the weight of the implants had a loss of 0.62 g in group 2, 0.73 g in group 3, whilst in the control group testes increased by 0.1 g. In pathological studies, the testicular structure was preserved in the control group; in group 2 there was 80% of inflammation and necrosis, Sertoli and Leydig cells were not visualized, and seminiferous tubules were found in two animals; in group 3 we found 75% of inflammation and a 60% necrosis, Sertoli cells could be visualized in only one specimen, while Leydig cells were seen in three. CONCLUSION: autologous transplantation of tes

Abstract: We report here the reappearence of Aedes aegypti in the Rimac district, and summarize the history of this mosquito species in Peru since its first detection in 1852. On March 17 2000 were found Ae. aegypti and Culex quinquefasciatus in Mariscal Castilla town, Flor de Amancaes, San Juan de Amancaes, El Altillo and Santa Rosa in the Rimac district, Lima Province.
