α-SMA在肝包虫囊肿周围组织中的表达

摘要

To evaluate the function of a-SMA in the formation of surrounding tissues of hepatic hydatid cyst , the expression of that in surrounding tissues of hepatic hydatid cysts from 50 patients was detected by using immunohistochemical methods . A special delaminated expression was observed in the external-layer of hepatic hydatid cyst and the liver . Further proof that the pericystic layer of hepatic hydatid cyst delaminated into two layers and their formation mechanism was different , which suggests that alpha smooth muscle actin plays an important role in the nature of hepatic hydatid cyst .%目的 探讨α-平滑肌肌动蛋白(α-smooth muscle actin;α-SMA)在肝包虫囊肿周围组织中的表达及与肝包虫囊肿病理过程的关系.方法 采用免疫组化的方法检测α-平滑肌肌动蛋白在50例肝包虫囊肿中的表达.结果 在肝包虫囊肿外膜及周围肝组织中α-平滑肌肌动蛋白出现阳性表达.结论 α-平滑肌肌动蛋白在肝包虫囊肿的病理生长过程中起着重要作用.
