The effects of methanol and water extracts of Taheebo were investigated on gastric secretion, gastric lesion and ulcer in rate. Experimental gastric lesion and ulcer was produced in rats using the following methods : HCl.aspirin-induced lesion, HCl.ethanol-induced lesion, indomethacin-induced ulcer and water-immersion stress ulcer model. In addition, the amount of gastric secretion in pylorus-ligated rats for 4 hours was determined. Water extracts of Taheebo significantly inhibited HCl.aspirin-induced gastric lesion at 1,000mg/kg, po in rats. Likewise, Water extracts of Taheebo caused significant inhibition of indomethacin-induced ulcer at oral dose of 1,000mg/kg. The lesion induced by HCl.ethanol was significantly reduced by both water and methanol extracts of Taheebo. It also showed significant antiulcer activity in water-immersion stress ulcer, respectively. In gastric secretion experiments, methanol extracts of Taheebo also showed significant inhibition of gastric juice secretion, acidity and acid output at doses 500 and 1,000mg/kg. These results may suggest that Taheebo shows antigastritic and antiulcerative action in rats in part by the inhibition of gastric juice secretion and acidity.
