摘要
对取自当前广州市肉品市场供食用的２００例猪肝和１００例牛肝的卫生品质进行了病理学分析，发现所研究的６８％猪肝和７７％牛肝存在着各种各样的病变。病变的种类多达２７种。病变不仅有肝细胞的萎缩和各种变性、水肿、囊肿、出血、坏死和钙化、肝组织细菌性污染和寄生虫虫卵附着等，还发现恶性肿瘤以及见于癌前期或癌症的肝细胞病理性核有丝分裂像。经常见到几种甚至十几种病变同时出现于同一个研究样品之中。
Two hundred specimens of pig liver and one hundred specimens of cattle liver from current Guangzhou market were analysed for hygienic quality by histopathology, histochemistry and ultrastructural routine. Besides bacterial contamination and parasite ovas in liver tissues, twenty-five kinds of lesions were discovered in sixty-eight percent (136/200) of pig livers and seventy-seven percent (77/100) of cattle livers. Besides atrophy and various degeneration of liver cells, edema, cyst, hemorrhage, necrosis and calcification in liver tissues, malignant tumor and pathologic nuclear mitosis in precancer or cancer liver cells were also seen. The research we have done showed that several to more than ten kinds of lesions often occurred in one specimen. The frequency of cirrhosis in these pig and cattle livers was very high. The various lesions described above could influence the nutritional value, hygienic quality,storage and public hygiene of food animal livers.
