降黑素(Melatonin)是松果腺分泌的一种激素。有报道,降黑素常使食蟹猴的排卵延缓,黄体期缩短,甚至不排卵。已知导致排卵的黄体生成素的峰值,正常是受血中雌激素水平升高的促进。本文进一步分析了给猴注射降黑素的过程中和注射以后,雌激素的分泌及其与黄体机能的关系。给7只具有规律周期的猴,皮下注射10毫克降黑素。从周期的第7或第9天开始到第17天,每天清晨9—11点注射。用其中6只猴做过未用药周期的对照。在对照周期和用药的过程中,每隔一天的清晨自股静脉取血。此后,在用降黑素以后的第1 Melatonin is a hormone secreted by the pineal gland. It has been reported that the reduction of melanoma often causes cynomolgus monkeys delayed ovulation, luteal phase shortened, or even ovulation. The peak of luteinizing hormone known to cause ovulation is normally impaired by elevated estrogen levels in the blood. This paper further analyzes the secretion of estrogen and its relationship with the function of the corpus luteum during and after the injection of melanin into the monkey. Seven monkeys with regular cycles were injected subcutaneously with 10 mg of melatonin. From the 7th or 9th day of the cycle to the 17th day, every morning at 9-11 injections. Six of these monkeys were used as controls for the unexecuted period. During the control cycle and medication, blood was taken from the femoral vein every other morning. Since then, after using melatonin in the first
