Abstract
Significant amounts of acetylcholine (ACh) were detected in each of the 3 lobes of the rat pituitary (3-6 pmol/anterior lobe, 3 pmol/intermediate lobe and 1.8 pmol/posterior lobe). In the anterior lobes of cyclic rats the levels of ACh varied with the estrous cycle, with daily peaks being observed on the days of proestrus and estrus. The occurrence of ACh, apparently as a humoral factor, appears to be unique to the anterior pituitary.
