title: Corticoidogenic effect of acetylcholine in bovine adrenocortical cells.
abstract: The effect of acetylcholine (ACh) on corticoidogenesis in primary cultured bovine adrenocortical cells was examined. One hour exposure to 10(-3) M ACh resulted in a stimulative effect on corticoidogenesis in the freshly isolated cells, and the effect of ACh grew intense during primary culture and reached the maximum on day 2. ACh showed the effect at a higher concentration than 10(-6) M. Thus the primary 2-day cultured cells were used. The corticoidogenic effect of ACh was inhibited by atropine but not by hexamethonium. The effect of ACh was dose dependent, and the extracellular Ca++ was obligatory in inducing the effect. These results suggest that the corticoidogenic effect of ACh may be due to an increase in Ca++-influx via muscarinic receptor in adrenocortical cells.
