RESUMEN
AIM: To investigate the protective effects and its mechanism of Ginkoglide A on stress ulceration in fats. METHODS: Wistar rats were randomly assigned to control, and Ginkgolides pretreatment group. The stress ulceration was produced by water immersion restraint, and gastric myoelectric activity during during was recorded by implanting electrodes in the stomach antrum smooth muscle. The malondialdehyde (MDA) concentration and superox- ide dismutase (SOD) activity in plasma, and gastric mucusal lesions were examined after the rat was killed. RE- SULT: Compared with the control group, previous intraperitoneal administratin of Ginkgolide A (5 - 20 mg/kg) not only had a highly significant decrease on stress - induced myoelectric activity disorder (P
