title: Studies on cyclic nucleotides in the adrenal gland. V. Adenylate cyclase in the adrenal medulla.
abstract: Effects of various chemical agents eliciting the catecholamine-release on the adenylate cyclase-cyclic AMP generating system have been studied in the secretory process of the bovine adrenal medulla slices. Cyclic AMP levels were not affected at the interval of the maximal increase of the catecholamine-release by acetylcholine, but increased gradually some time after the end of the release/or at the beginning of the restoration of catecholamine in the medulla tissue. This delayed increase in the medullary cyclic AMP is not attributed to a direct involvement in 'stimulus-secretion coupling process' of the medullary secretion, but rather may be caused by release of intracellular catecholamine.
