用拟交感胺药物肾上腺素(EPI)、去甲肾上腺素(NE)、苯肾上腺素(PE)及异丙基肾上腺素(ISO)为肾上腺素α与β受体激动剂,酚妥拉明与心得安分别为肾上腺素α与β受体阻断剂,分析在不同性功能状态下(雌激素处理、早孕、晚孕及产后)的小鼠子宫肾上腺素受体的性质,并对性功能状态与受体关系作了研究。 经雌激素处理的早孕小鼠子宫,用心得安0.1mM可阻断ISO的抑制效应;也使EPI、NE及PE Epinephrine (EPI), norepinephrine (NE), phenylephrine (PE) and isoproterenol (ISO) were used as adrenergic alpha and beta receptor agonists, Propranolol and adrenaline α and β blockers respectively. The properties of uterine adrenergic receptors in mice under different sexual functions (estrogen treatment, early pregnancy, late pregnancy and postpartum) were analyzed, and their sexual function status The relationship with receptors was studied. The estrogen-treated uterus of early pregnant mice, with 0.1% of the heart can block the inhibitory effect of ISO; EPI, NE and PE
