通过放射免疫测定法连续 60 天测量 5 只雌性鸮猴血浆样本中雌酮和孕酮的循环水平。两种类固醇都表现出周期性波动，根据最低点到最低点的间隔，卵巢周期估计为 15.92 +/- 0.26 天。还测量了每日尿液样本中雌酮和孕二醇-3 α-葡萄糖苷酸的水平。尿类固醇的波动反映了血浆中观察到的波动。氯胺酮镇静对周期长度没有影响。血浆孕酮和雌酮的峰值分别为250.48+/-11.37和3.59+/-0.066ng/ml。这些猫头鹰猴的卵泡期和黄体期之间没有明显的激素区别。
Circulating levels of oestrone and progesterone were measured by radioimmunoassays in plasma samles from 5 female owl monkeys on 60 consecutive days. Both steroids exhibited cyclic fluctuations and based on nadir to nadir intervals the ovarian cycle was estimated to be 15.92 +/- 0.26 days. Levels of oestrone and pregnanediol-3 alpha-glucuronide were also measured in daily urine samples. The fluctuations of urinary steroids reflected those observed in plasma. Ketamine sedation had no effect on the length of the cycle. Peak values of plasma progesterone and oestrone were 250.48 +/- 11.37 and 3.59 +/- 0.066 ng/ml respectively. There was no clear hormonal distinction between the follicular and luteal phase of the cycle in these owl monkeys.
