Effect of LH-RH and hypothalamic extracts on 3'-5'-cyclic-AMP pituitary levels of immature and adult female rats in vivo.
Adult female rat hypothalamic extract and LH-RH increased the 3'-5'-cyclic-AMP (cAMP) level of immature pituitary in vivo, while immature female rat hypothalamic extract had the opposite effect. LH-RH and immature female rat hypothalamic extract did not change the cAMP pituitary levels 60 min after injection to adult female rats.
