鸡马立克氏病外周神经的病理组织学研究

用光镜、电镜及特殊染色法对兰州某鸡场２０例自然发生的马立克氏病鸡进行了外周神经的病理组织学研究。结果表明，外周神经主要表现增生性和渗出性病变，前者以瘤细胞增生为主，伴以脱髓鞘和雪旺氏细胞增生；后者以浆液渗出为特征，并发生神经纤维轴索肿胀和髓鞘变化，瘤细胞浸润很少。本文首次报告了马立克氏病的内脏－皮肤－神经混合型病变，还探讨了瘤细胞增生与脱髓鞘、神经水肿之间的关系。

HISTOPATHOLOGICAL STUDIES ON THE PERIPHERAL NERVE IN CHICKENS WITH MD

Pathological studies were carried out on peripheral nerves in twenty field cases of MD from a certain poultry farm in Lanzhou The results showed that the changes of peripheral nerves were mainly proliferative and exudative lesions The pormer was characterized by the proliferation of lymphoid tumor cells,demyelination of nerves and proliferation of both Schwann cell and reticular fibre The latter was greatly impressed by the presence of serous exudate,with a slight infiltration with small lymphocytes and plasma cells This is the first report about the viscera skin nerve mixed type of MD The relationship of tumorous cell proliferation,demyelination and nervous edema is approached
