大鼠子宮宮腔粘連模型的建立及評(píng)價(jià)指標(biāo)
[Abstract]:Endometrial injury is the main cause of uterine cavity adhesion. Establishing an effective animal model of endometrial injury is an indispensable supporting condition to study the occurrence, development and therapeutic response of this kind of disease. The (Rattus norvegicus) endometrial injury model of rats was made by intrauterine injection of 95% ethanol. The number of embryo implantation was measured to analyze the effect of endometrial injury on the fertility of rats. The thickness of endometrium, the number of glands and the area of fibrosis were observed. The effects of ethanol treatment on endometrium were analyzed, and the expression levels of cytokeratin (CK-19) and wave protein (Vimentin) were detected, and the proliferation and differentiation of epithelial cells and interstitial cells were analyzed as well as the degree of endometrial injury. The results showed that the uterus of the normal group was smoother and more resilient than that of the injured group. In the injured group, the fertility rate decreased significantly (P0.01), the thickness of endometrium became thinner (P0.01), the number of glands decreased significantly (P0.01), the area of fibrosis increased significantly (P0.01), and the expression of CK-19 and Vimentin decreased significantly. The results suggest that the rat model of endometrial injury has been successfully established.
