Synthesis of growth hormone, prolactin, and proopiomelanocortin by intact adult ovine pituitary tissue in vitro.

abstract：:This study was performed to test the hypothesis that reflex increases in heart rate, PRA, and plasma concentrations of vasopressin, angiotensin-II, ACTH, and cortisol are reduced during pregnancy. The hypothesis was tested by measuring, in pregnant and nonpregnant conscious dogs, changes in arterial and atrial pressur...
