AIM To study the protective effects of Weitongling decoction (WTL) on gastric mucosa.METHODS Rats with gastric lesion induced by dehydrated alcohol were used to observe the gastric mucosalblood flow (GMBF), rats with spleen deficiency syndrome induced by reserpine were applied to investigatethe D-xylose absorption rate, the Alcian blue binding properties of gastric wall, the gastric acid secretion andthe activity of pepsin.RESULTS Remarkable increases in GMBF (19.5±3.5 mL/min, 20.4±3.3 mL/min respectively in largedose group and small dose group, P<0.01), in Alcian blue binding properties of gastric wall (2.497 mg±0.138 mg, 2.223 ug±0.186 mg respectively in large dose group and small dose group, P<0.05) and in D-xylose absorption rate (1.287±0.043, 1.294±0.019 respectively in large dose group and small dose group,P<0.05) were found after administrations of WTL, while no significant alteration in gastric secretion wasshown and in vitro WTL did not neutralize gastric acid.CONCLUSION WTL can improve the Spleen deficiency syndrome, strengthen the gastric mucosal barrier,and thus protect gastric mucosa against injury agents.
