对网状内皮组织增生症病毒（REV）引起的腺胃炎的自然发病鸡主要脏器进行了病理组织学观察，为该病发生机制提供理论依据。采集患鸡的主要脏器，进行石蜡包埋、HE 染色，显微镜下观察病理组织学变化。结果显示，患鸡的心肌纤维间隙增宽，有淋巴细胞浸润；肝脏出血，肝细胞水泡样变，淋巴细胞浸润；肺脏淤血、出血，炎性细胞浸润；脾脏出血，动脉周围淋巴鞘增厚；法氏囊淋巴细胞数量减少；十二指肠出血、淋巴细胞浸润；腺胃乳头出血，黏膜下层和固有层水肿，有的腺体充血、水肿，大量淋巴细胞浸润。结果表明，患鸡出现了广泛性的组织损伤，同时伴随着机体各器官明显的炎症反应，其中腺胃的炎症反应最为明显。

To provide the theoretical basis for the mechanism of the infectious proventriculitis in chickens, the tissues of the sick chickens diagnosed as infectious proventriculitis caused by reticuloendotheliosis virus (REV)were collected,fixed immediately for making paraffin section,and histopathological lesions of these tissues were observed by light microscope.The result showed that intercellular space between cardiac myocytes were widen;hemorrhage in the liver and degeneration in the hepatocytes;congestion and hemor-rhage in the lung,hemorrhage in spleen,and periarteriolar lymphoid sheaths were widen;the number of lymphocytes in bursal decreased;hemorrhage in the duodenum;hemorrhage in nipple of proventriculus, oedema of submucous and mucous.Many lymphocytes infiltrated in all the tested tissues.The results sug-gested that extensive lesions and inflammatory reactions in the tissues,especially in proventriculus,were the main characteristics of infectious proventriculitis in chickens.
