正交试验优化大鼠子宫内膜异位症模型

目的通过正交试验优化子宫内膜异位症大鼠模型的制备方法。方法采用自体移植法复制大鼠子宫内膜异位症模型和四因素二水平的正交设计,以移植物体积大小为评价指标,观察不同影响因素对大鼠子宫内膜异位症模型形成的影响及病理形态学变化。结果子宫内膜最佳种植部位在子宫旁韧带。发情情况及子宫内膜种植方向对实验结果的影响不明显。内膜不与肌肉层分离和外加雌激素对大鼠异位内膜生长起着关键性的作用。4个影响因素重要性依次为注射雌激素>不分离肌肉层>种植方向、发情情况。结论通过优化试验方法,可有效提高子宫内膜异位症大鼠模型的造膜效果,为科学评价子宫内膜异位症的药物研究提供技术平台。

Optimizing the establishment of endometriosis model in rats by orthogonal experiment

Aim To probe into the best conditions for the establishment of endometriosis model in rats by the orthogonal experiment method.Methods Autotransplantation was used to establish the endometriosis model in rats by the orthogonal experiment method in which four main factors were considered to optimize the condition of model,according to the volume of heterotopic endometrium.Results The para ligament of uterus was the best place for transplanting.Both dissecting muscular layer and injecting estrin played an important role in the establishment of endometriosis model in rats. The value of four factors decreased progressively according to the injection of estrin,the dissection of muscular layer,the direction of endometrium implantation and oestrus.Conclusions By optimizing the condition for the establishment of endometriosis model in rats by orthogonal experiment,the volume of heterotopic endometrium was improved.A technology platform for pharmacodynamics research was thus offered.
