METHODS: Sprague-Dawley rats were randomly divided into four groups: sham operation without ginkgo, sham operation with ginkgo, duodenal ulcer without ginkgo, and duodenal ulcer with ginkgo. Rats with duodenal ulcer were induced by 500 mL/L acetic acid. Rats with ginkgo were intravenously injected with Ginkgo biloba extract from the tail at a dose of 0.5 mg/(kg/d) for 7 and 14 days. RESULTS: Pathological result showed that duodenal ulcer rats with ginkgo improved mucosal healing and inflammation compared with those without ginkgo after 7 d treatment. After 14 d treatment, duodenal ulcer rats with ginkgo significantly increased weight gain (34.0+/-4.5 g versus 24.5+/-9.5 g, P<0.05) compared with those without ginkgo. Duodenal ulcer rats significantly increased cell proliferation (27.4+/-4.0 and 27.8+/-2.3 BrdU-labeled cells in duodenal ulcer rats with and without ginkgo versus 22.4+/-3.5 and 20.8+/-0.5 BrdU-labeled cells in sham operation rats with and without ginkgo, P<0.05) compared with sham operation rats. Mucosal prostaglandin E(2) concentration significantly increased by 129% (P<0.05) in duodenal ulcer rats with ginkgo compared with that in those without ginkgo. Duodenal ulcer rats without ginkgo significantly decreased superoxide dismutase activity in the duodenal mucosa and erythrocytes (19.4+/-6.7 U/mg protein versus 38.1+/-18.9 U/mg protein in the duodenal mucosa, and 4.87+/-1.49 U/mg protein versus 7.78+/-2.16 U/mg protein in erythrocytes, P<0.05) compared with sham operation rats without ginkgo. However, duodenal ulcer rats with ginkgo significantly increased erythrocyte superoxide dismutase activity (8.22+/-1.92 U/mg protein versus 4.87+/-1.49 U/mg protein, P<0.05) compared with those without ginkgo. Duodenal ulcer rats without ginkgo significantly increased plasma lipid peroxides (4.18+/-1.12 micromol/mL versus 1.60+/-1.10 micromol/mL and 1.80+/-0.73 micromol/mL, P<0.05) compared with sham operation rats without ginkgo and duodenal ulcer rats with ginkgo during the experimental period. CONCLUSION: Ginkgo biloba extract can improve weight gain and mucosal healing in duodenal ulcer rats by the actions of cytoprotection and antioxidation. ------>tmu_sno=None ------>sno=10615 ------>authors2=Hung H ------>authors3=Chen SH ------>authors4=Fang CL ------>authors5= ------>authors6= ------>authors6_c=None ------>authors=Chao JC* ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c=None ------>publish_area=None ------>updateTitle=Effects of Ginkgo biloba extract on cytoprotective factors in rats with duodenal ulcer. ------>language=2 ------>check_flag=None ------>submit_date=None ------>country=None ------>no=4 ------>patent_SDate=None ------>update_bywho=None ------>publish_year=2004 ------>submit_flag=None ------>publish_month=None |
