孕酮对改变子宫肌细胞生理功能、激发子宫内膜DNA、RNA的合成、形成脱膜、孕卵着床、胚胎发育和分娩启动等都有密切关系。因此,对妊娠期动物体内孕酮分布和代谢的研究受到重视。Lamus等应用高放射比度的~3H—孕酮证实妊娠子宫对孕酮有选择性潴留作用。章志文等比较了单侧妊娠大鼠孕侧子宫早、中、晚期摄取~3H—孕酮的能力,证明大鼠妊娠中期孕侧子宫摄取~3H—孕酮能力明显大于非孕侧。本实验为了验证小鼠妊娠子宫
Progesterone to change the physiological function of uterine muscle cells, stimulate endometrial DNA, RNA synthesis, the formation of stripping, pregnancy egg implantation, embryonic development and birth are closely related. Therefore, the study of the distribution and metabolism of progesterone in pregnant animals has received great attention. Lamus and other applications of high-radiofrequency ~ 3H-progesterone progesterone pregnancy confirmed selective retention of the role. Zhang Zhiwen et al compared the ability of uptake of 3H-progesterone in the early, middle and late stages of unilateral uterine pregnancy in unilateral pregnant rats, demonstrating that the 3H-progesterone uptake capacity of the pregnant uterus in the second trimester pregnancy was significantly greater than that in the non-pregnant side. This experiment in order to verify the pregnancy of the mouse uterus
