The rabbits were exposed twice to stress, fixation to a frame in the supine position, for 60 min. Contractile activity of all portions of the large intestine was shown to increase significantly during the poststress period. These changes were not observed under conditions of blockade of muscarinic and nicotinic receptors. This state can be considered as dyskinesia impairing large intestinal transit of chyme.
