摘要
经60Coγ线照射大鼠肝区,通过光镜(常规HE染色,肝细胞内糖原染色、胶原纤维及网状纤维染色)、电镜和图像分析仪,定量研究了照后1年肘脏的病理改变。结果表明,30Gy组在照射后1年内逐渐发生了放射性肝纤维化病变。在肝纤维化发生过程中,肝细胞内糖原颗粒含量进行性减少,间质中胶原纤维含量进行性增加,网状纤维于照射后1~3个月呈进行性增加。照射后6个月因肝细胞坏死、肝索塌陷,网状纤维呈减少趋势。
By means of optic microscope (HE,PAS,collagenous and reticular fiber staining),electron microscope and image analysis,the liver lesions within one year after local irradiation with 60 Co γ rays were studied quantitatively and dynamically.The results showed that hepatic radiation fibrosis occurred in 30 Gy irradiatied rats.In the course of fibrosis,the granules of glycogen in hepatocytes were decreased progressively;the collagenous fiber progressively increased;reticular fibers significantly increased in 1 3 months after irradiation and decreased after 6 months due to necrosis of hepatocytes and collapse of hepatic cell cords.The significance of quantitative changes in the formation of hepatic radiation fibrosis is discussed.
