马瘟的病理形态学变化

本项研究工作对非洲马瘟病畜进行了病理学检查。肺型非洲马瘟的主要病理变化为急性肺水肿并伴有出血性素质变化,浆液性枝气管淋巴结炎,胸液及心包液增量,胃及小肠的卡他性炎,实质器官如心、肝、肾等的充血及变质性变化,脾无肿大或轻度肿大。心型非洲马瘟的主要病理变化为皮下胶样水肿并伴有明显的心外膜的变质性变化,其他变化与肺型马瘟相似。研究结果表明,马瘟的病型不同,其病理学变化是不完全相同的。这对马瘟的诊型及不同病型的鉴别诊断具有一定的意义。

THE PATHOMORPHOLOGICAL CHANGES OF AFRICAN HORSESICKNESS(A.H.S.)

In this research work the sick animals with A. H. S. were examined pathologically. The principal pathological changes of A. H. S. of pulmonary type are acute pulmonary edema, accompanied with haemorrhagic predisposition changes, serous bronchial lymphoditis, the increase of thoracic fluid, catarrhal inflamation of stomach and small intestine, the congestion and deteriorative changes of parenchymal organs such as heart, liver, kidney, etc, no swelling or slight swelling of spleen. The principal pathological changes of A. H. S. of cardiac type are hypodermic gelatinous edema of the head and neck, accompanied with apparent pericardiac degenerative changes. The other changes are similar to those of A. H. S. of pulmonary type. The results of this research indicate that with the difference of the types of A. H. S. the pathomorpholgical changes are not completely the same. lt is significant to some extent in the diagnosis of A. H. S. and differentiation of different types of this disease.
