Methods: By using the model of exhausting exercise-induced estrous cycle inhibited rats to test the expression of MMP-2 and MMP-9 of uterus in rats by using immune histochemistry of SABC and combining with image analysis to analyze.

• 方法:以长期力竭运动所致动情周期抑制大鼠为模型,用免疫组织化学SABC法检测了大鼠子宫基质金属蛋白酶2-和-9(MMP-2和MMP-9)的表达,并结合图像分析系统进行分析。
