"Estudo laboratorial da cicatrização de córneas humanas após debridamento epitelial" / Laboratory study of the wound healing response to epithelial scrape injury in the human corneaAmbrósio Júnior, Renato 19 May 2004 (has links)
Objetivo: Verificar resposta após debridamento epitelial de córneas humanas. Métodos: Córneas normais foram submetidas a debridamento antes da cirurgia de enucleação. Realizou-se histologia, TUNEL, Ki67, SMA e microscopia eletrônica. Resultados: Seis córneas foram debridadas e preservadas entre ½ e 65 horas, apresentando apoptose nos ceratócitos do estroma anterior. Células estromais em proliferação foram observadas apenas no tempo de 65 horas. Miofibroblastos não foram encontrados. Uma córnea serviu de controle. Conclusões: Os eventos observados em córneas humanas após debridamento epitelial, apoptose e proliferação dos ceratócitos, foram semelhantes aos descritos em animais de experimentação / Purpose: To examine the early wound healing response to epithelial scrape in human corneas. Methods: Normal corneas had epithelial scrape prior to enucleation. Histology, TUNEL assay, Ki67, SMA and transmission electron microscopy were performed. Results: Epithelial scrape was performed in six corneas from ½ to 65 hours prior to preservation. Keratocyte apoptosis was detected in the anterior stroma in all scraped corneas. Keratocyte proliferation was detected exclusively 65 hours after scrape. No myofibroblast was detected. One cornea was not scraped (control). Conclusion: Results obtained in human corneas (keratocyte apoptosis and proliferation) were similar to animal models
