Abstract

|
The apoptotic process of gastric mucosa triggered by induction of proapoptotic gene expression, such as Bax. Stress-inducing factors may affect Bcl-2/Bax ratio and thus the rate of apoptosis through modulation of the expression of both proteins depending upon the experimental model. TGF- is believed to be essential in wound healing for regulation of cell growth and differentiation and is known to be involved in tissue repair and remodeling. The polypeptide growth factors, such as vascular endothelial growth factor(VEGF), regulate essential cell functions involved in tissue healing including cell proliferation, migration, and differentiation. The purpose of this study was to investigate whether the oral administration of (HYT) would have protect effects on gastric ulcer in rat. Sprague-Dawley rats (n=40) were randomly divided into 4 groups ; Normal, Saline, Cimetidine and HYT group. The saline, cimetidine and HYT extract were orally administrated to each group and gastric ulcer was induced with HCl/EtOH solution. After 1 hour, the stomachs were collected for histological observation and immunohistochemistry. In Results, the wound healing of gastric ulcer was promoted by HYT and the significant alterations of BAX/Bcl-2, TGF- and VEGF proteins in gastric mucosa were observed. These results suggest that Fritillaria ussuriensis extract promotes wound healing and has protective effects on gastric ulcer in rats.
