Induction of somatogenic receptors in livers of hypersomatotropic rats.

abstract：:The current study was designed to investigate the ability of prostaglandin F2 alpha (PGF2 alpha) to activate a second messenger system (phosphatidylinositol pathway) in corpora lutea (CL) of rhesus monkeys. Activation of this pathway was assessed by monitoring the hydrolysis of phosphatidylinositol to inositol phospha...
