摘要
迄今为止已明了牛膀胱肿瘤性血尿症在我国的分布相当广泛,且与蕨属植物(蕨Pteridium aquilinum和毛叶蕨Pteridium revolutvm)的地理分布密切相关。在贵州、四川、湖南、云南、广西、陕西及台湾的一些地区本病的发病率相当高,对农牧业生产已构成较大威胁。而在没有慢性血尿症或缺乏蕨属植物分布的地区,本病十分罕见。水牛亦可罹患,但发病率远不及黄牛高。本病无明显性别差异,5～19岁的牛均可患病而犊牛很少发生。在已收集到的膀胱肿病例中,恶性高于良性。肿瘤的组织学类型多样。值得注意的是为数较多的恶性肌源性肿瘤和相当数量的膀胱肿瘤,是上皮与间叶的肿瘤成分或两种不同的间叶成分构成的“复合瘤”。提示了牛膀胱肿瘤的组织学类型有一定的地区差异性。
Up to now, it has been confirmed that the chronic bovine hematuria vesicalis due to tumors is common in China and assiciated with the geographical bistribution of bracken ferns (Pteribium aquilinum and Pteribium revolutum). The incidence of the disease in some places of Guizhou, Sichuan, Hunan, Yunnan, Guangxi, Zhejiang and Taiwzn is quite high. The Morbidity of the disease in water buffalo is much less than in cattle. But young animals usually do not develop the disease.In bladder tumors we collected, the number of malignant tumors was more than that of benign tumors. A great variety of histological type of the tumors have been noticed. Many of them were malignant myogennic tumors, some of the others belong to mixed tymors consisting of neoplastic epithelial and mesenchymal elements or two kinds of different mesenchmal elements. It was suggested that the histological tyre of bovine urinary bladder tumors varies with different geogrgphical regions.
