The Changes of Serum Hormones in Female Rats after an Exhaustive Swimming

LANGUAGE NOTE | Document text in Chinese; abstract also in English.The changes of serum hormones during strenuous exercise were studied. 40 female Sprague-Dawley rats were randomly assigned into two groups— the exhaustive swimming group rats and the control. They were sacrificed after exhaustive swimming. Changes in the exercised rats indicated that: 1) the concentrations of serum estradiol (雌二醇, E2) decreased significantly, 2) no significant change in progesterone (孕酮, P, 3) the level of serum cortisol (皮質酵, C)was higher in the exercised rats, 4) the testosterone (睾酮, T) level remained unchanged in both groups, 5) triiodothyronine (二碘甲狀腺胺酸,T3) and thyroxine (四碘甲狀腺胺酸, T4) levels were lower than those of the control group. It appears the changes of serum E2 and P are related to adrenal and thyroid functions and they in turn affect the ovary indirectly.本文章利用40只大白鼠探討有關在力竭性游泳後血清激素的變化。研究員把大白鼠分成實驗組和對照組經測試後分析其結果及作出討論。
