ACTH CONTENT IN THE PITUITARY GLAND IN RATS UNDER CONDITIONSOF DEHYDRATION AND HEAT EXPOSURE

Abstract

ACTH content in the anterior pituitary lobe is diminished after administration of hypertonic saline, injection of Pitressin and exposure to severe heat, whereas ACTH content in the posterior lobe was not altered by these treatments. Water deprivation as well as starvation caused a marked reduction in the ACTH content in both lobes of the pituitary gland.
