Rats pretreated orally with AFSAB at doses of 400 and 800\u2005mg\/kg showed significant decreases of gastric lesion scores in ethanol (62% and 98%) and hypothermic restraint\u2010stress (89% and 88%) models but exerted no significant influence on indomethacin\u2010induced acute or acetic acid\u2010induced chronic ulceration. In pylorus\u2010ligated rats, AFSAB significantly decreased the basal as well as bethanechol\u2010stimulated gastric secretory volume and the total acidity with an elevated pH value. AFSAB failed to modify the gastric mucus and the gastric wall nonprotein\u2010sulphydryl content. These results point to a possible antisecretory effect of AFSAB which account for the observed antiulcer activity in ethanol and hypothermic restraint\u2010stress induced models of acute gastric ulceration.
