用薄层层析,荧光光密度法测定了小白鼠卵巢在不同时期及不同生理状态下酪氨酸含量。结果表明:未成年小鼠卵巢内酪氨酸是痕迹量;成年小鼠排卵后卵巢内酪氨酸含量明显高于排卵前;妊娠初期小鼠卵巢酪氨酸含量逐渐增高,到第七天达高峰,以后开始减少,妊娠终止为痕迹量。表明小鼠卵巢内酪氨酸含量变化与机能状态密切相关。 The content of tyrosine in ovary of mice at different periods and different physiological states was determined by TLC and fluorescence spectrophotometry. The results showed that the amount of tyrosine in the ovary of young mice was trace amount; the content of tyrosine in the ovary after ovulation was significantly higher than that before ovulation in adult mice; the content of tyrosine in the ovary increased gradually in the first trimester of pregnancy, Peak, later began to reduce the amount of traces of pregnancy termination. That the mouse ovarian tyrosine content and functional status are closely related.
