屠宰牛羊肝脏组织的病理学观察

Histopathological Observation of Liver of Slaughter Cattle and Sheep

为了观察感染戊型肝炎的牛、羊屠宰后肝脏的病理变化,从屠宰场流水线分别采集牛、羊肝脏样品150份和120份,切成5×1×1 cm3的组织块,用10%的中性福尔马林固定液固定后制作病理学切片,通过苏木精-伊红染色进行观察。检测结果为牛羊正常肝脏比例分别占48%和53.3%,其余肝脏出现炎性细胞浸润、肝细胞变性坏死、肝小叶周边带变性坏死、汇管区胆管增生、肝细胞萎缩、纤维结缔组织增生、胆管壁增生明显、中央静脉周围淋巴细胞浸润、肝窦内出血、肝小叶肝窦内水肿等多种病理变化,表现程度不同,各种病变的比例占1%～5%,本试验的结果可为牛羊肝脏的屠宰检疫提供参考。
