Abstract
The concentration of plasma free tryptophan was shown to undergo a regular and statistically significant fluctuation through the four phases of the oestrous cycle of the rat. The highest concentration of plasma free tryptophan was observed during oestrus. During metoestrus the concentration of plasma free tryptophan decreased by 25% to the lowest observed level; thereafter it gradually increased during dioestrus and pro-oestrus. The concentration of plasma total tryptophan was found to be unchanged during the oestrous cycle of the rat.
摘要
结果显示，在大鼠发情周期的四个阶段中，血浆游离色氨酸浓度呈现出规律且具有统计学意义的波动。发情期血浆游离色氨酸浓度最高。在间情期，血浆游离色氨酸浓度下降25%，降至观察到的最低水平；此后，在动情后期和发情前期逐渐升高。研究发现，大鼠发情周期中血浆总色氨酸浓度没有变化。
