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 cm^3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。

This paper introduced the pathology of livers of slaughtered sheep infected with hepatitis E in Urumqi,a total of 150 cattle liver samples and 120 sheep liver samples were collected,the tissues of these organs were fixed using 10% formalin solution,embedded by paraffin,embedded tissues were sliced up,stained and then observed.The results showed that the proportion of normal cattle and sheep liver was 48% and 53.3%,respectively.Liver lesions included inflammatory cell infiltration,degeneration and necrosis of hepatocytes,hepatic lobule with degeneration and necrosis around portal bile duct hyperplasia,liver cell atrophy,fibrous connective tissue hyperplasia,bile duct hyperplasia,lymphocytic infiltration around the central vein,sinusoidal hemorrhage and hepatic lobule sinusoidal edema.The study provides a basis for slaughter and quarantine of cattle and sheep.
