患暴发性病毒病的中国对虾肝胰脏病理变化

PATHOLOGICAL CHANGES IN THE HEPATOPANCREAS OF PENAEUS CHINENSIS WITH BROKENTHROUGH VIRAL DISEASE

摘要:

本文报导上海地区患暴发性病毒病的中国对虾肝胰脏病理变化的研究结果。组织病理变化方面，肝胰脏呈以弥漫性坏死为主的变质性病变；在肝胰脏的上皮细胞核内见到2种病毒颗粒，还见到2种球形包涵体，其浮尔根染色反应为阳性。生化病理变化方面，病虾肝胰脏的酯酶（EST）和超氧化物歧化酶（SOD）的活性显著减弱，表明病虾代谢功能与免疫功能明显衰退。

Abstract:

This paper reports the research results of pathology of the hepatopancreas of Penaeus chinensis caused by brokenthrough viral disease in Shanghai area. Histopathological changes: The pathological changes in hepatopancreas were mainly characterised by the diffuse necrosis and two kinds of virion and two types of ball - shaped occlusion bodies positively stained by Feulgen Reagent were found in epithelial cell nucleus. Biochemical changes: The relatively decreased activities of EST and SOD in the hepatopancreas of diseased shrimp were indicated that the function of metabolism and immunization decreased significantly by the viral disease.
