鸡淋巴—网状细胞性肿瘤的超微结构比较

ULTRASTRUCTURAL COMPARISON OF LYMPHOCYTIC AND RITICULARCYTIC TUMOURS IN CHICKENS

对鸡马立克氏病、淋巴性白血病和网状内皮细胞增殖病进行了超微结构的比较.结果证实,鸡马立克氏病引起增殖的细胞呈多形性,并能见到特征性的马立克氏病细胞,肿瘤细胞的成分,常见有成淋巴细胞,中、小淋巴细胞及少量网状细胞和组织细胞等不同类型的细胞;淋巴性白血病为同一类型的成淋巴细胞(?)其特征性变化是在肿瘤细胞的核内出现核小囊;网状内皮细胞增殖病为相同类型呈树突状的网状细胞.

Ultrastructural comparative studies on Marek's disease(MD),lymphocytic leukemia(LL)and reticuloendotheliosis(RE)were performed by electron-microscopy.The results showed that thecharacteristics of MD were pleomorphism of cells,the main compositions were lymphoblasts,small andmedium-sized lymphocytes,reticular cells,histiocytes and regressed Marek's cells.Morphologic features ofLL were the homomorphic lymphoblastic cells and nuclear pockets;the morphologic characteristics of REwere the homomorphic reticular cells with long processes extenting from several directions.
