Abstract
By the method of Van Liere, propulsive motility of the small intestine was studied after adrenalectomy in male albino rats. Increased motility occurred in 67% of the adrenalectomized rats as compared with the motility in intact, sham-operated, or partially starved controls. Reduced motility after adrenalectomy occurred in 10%. An explanation is suggested based on disturbances in the K balance and the fact that hyperpotassemia may stimulate smooth muscle.
