摘要：
The effects of jugular infusions of adrenalin and the beta-adrenergic receptor antagonist propranolol on plasma concentrations of progesterone and oxytocin were examined at 2 different stages of the caprine estrous cycle. Adrenalin (25 mu g.kg(-1)h(-1)) significantly (P < 0.05) increased oxytocin secretion on Day 3 and Day 10 of the cycle (estrus = Day 0); progesterone concentrations were significantly (P < 0.05) elevated on Day 10 alone. Propranolol had no effect on progesterone secretion yet significantly (P < 0.05) reduced oxytocin concentrations on Day 3.
