Role of neuropeptides in cardiomyopathies.

abstract：:A study was made of the effect of adrenalectomy over different periods of time (6, 15 and 21 days) on exocrine pancreatic secretion in the rat in basal conditions and under stimulation with CCK. It was observed that adrenalectomy does not alter the rate of pancreatic flow but the response capacity to CCK is depressed....
