摘要: 目的:观察核糖核酸(RNA)对日本血吸虫病病兔肝纤维化的阻抑效果。方法:54只3月龄家兔随机均分为正常组、感染组及RNA组。于肌注RNA后第40d、70d及100d,各组随机选6只兔抽血及取肝组织,通过光镜、电镜观察其组织病理变化,放射免疫法测定血浆HA含量,紫外分光光度法测定肝组织HYP,IBAS图像分析仪测定肝组织胶原纤维分布面积百分比,用潘孺孙法测定肝组织胶原纤维含量。结果:与感染组相比较,RNA组胶原纤维未见明显增加,而肝细胞核仁增大,粗面内质网及其附着颗粒增多,贮脂细胞周围胶原纤维减少,血浆HA、肝组织HYP、胶原纤维分布面积百分比及胶原纤维含量均显著降低。结论:RNA对日本血吸虫病病兔肝纤维化具有早期预防作用。

Abstract: AIM: To study the effect of ribonucleic acid (RNA) against schistosomal hepatic
fibosis in rabbits. METHODS: 54 rabbits were randomly and equally divided into normal group,
infected group, and RNA group. On the 40,70,100th day after RNA i.m. injection, 6 rabbits from
each of the above 3 groups were killed and their plasma and liver were examined by way of
biochemistry and pathology. RESULTS: Compared with the infected group the collagen fiber of
liver in RNA group was less produced, the hepatic cellular nucleolus was enlarged, the number of
rough endoplasmic reticulum (RER) and the granules on the RER were increased, the collagen fiber
around fat-storing cell was decreased, the content of hyaluronic acid in plasma, the hydroxyp
roline level in liver tissue, the percentage of collagen fiber distribution and the collagen
fiber level in liver tissue of RNA group were significantly reduced.CONCLUSION: RNA might play a
role in the prevention of schistosomal hepatic fibrosis.
