皮下注射子宫内膜法建立Lewis大鼠腹壁子宫内膜异位症模型

Establishment of endometriosis model by abdominal wall subcutaneous injection of endometrium in Lewis rats

目的建立Lewis大鼠皮下子宫内膜异位症(EM)模型。方法以同系大鼠作为供体,取子宫内膜,采用皮下注射法对28只大鼠行皮下造模手术,术后第7天及第21天取异位子宫内膜结节行HE染色和病理组织学观察。结果实验大鼠均成活,腹壁子宫内膜异位种植成功率100%。子宫内膜在腹壁内生长,呈隆起囊状小包块,具有正常子宫内膜基本组织结构。结论以同系大鼠子宫内膜皮下注射法成功地建立了Lewis大鼠腹壁EM模型,可用于EM研究。

Objective To establish a endometriosis model by abdominal subcutaneous injection of endometrium in Lewis rats. Methods Endometrium of Lewis rats was subcutaneously injected into abdominal wall in 28 Lewis rats. On the 7th day and 21st day after surgery, the heterotopic nodules were taken out for HE staining and pathological observation. Results All 28 rats were survived with the ectopic endometrium growing in abdominal wall. The ectopic endometrium nodules grew like a small cystic mass and with the basic organizational structures of normal endometrium under microscope. Conclusion The endometriosis model of Lewis rats has been successfully established, which is beneficial to the study of endometriosis.
