Abstract
We have reported that acute restraint stress inhibits small intestinal moti lity in rats. In order to clarify this inhibitory mechanism, we examined th e effects of alpha- and beta -adrenergic antagonists on the inhibition of s mall intestinal motility induced by restraint stress. This inhibition under went recovery by propranolol (beta (1)/beta (2)-antagonist) or SR59230A (be ta (3)-antagonist), but not by atenolol (beta (1)-antagonist), ICI-118,551 (beta (2)-antagonist), prazosin (a,antagonist) or yohimbine (alpha (2)-anta gonist). These results suggest that beta (3)-adrenoceptors play an importan t role in the inhibition of small intestinal motility caused by restraint s tress.
