摘要: 目的 观察SHIV-B'whu感染中国猕猴的组织病理学变化. 方法 SHIV-B'whu感染中国猕猴,4次传代(P1~P4),定时测量动物体温变化,对各代感染的猴在第14天处死,进行病理学解剖观察,并且对全身主要脏器以及多处淋巴结组织取材做病理分析.结果 中国猕猴在感染急性期体温有短暂升高,经病理分析,4代感染猴均有典型的间质性肺炎特征,肝组织有点状或灶性坏死,淋巴窦扩张,淋巴滤泡萎缩,淋巴细胞减少,淋巴结出现噬红细胞现象,组织巨噬细胞免疫组化染色阳性率从P1到P4逐步增加,从3.5%到22%.结论 SHIV-B'whu能成功感染中国猕猴,引起与HIV感染人后所相似的免疫病理学变化.

Abstract: Objective To study pathological changes on Chinese rhesus monkeys with recombined Simian/Human Immunodeficiency virus. Methods Chinese rhesus monkeys were inoculated with a serial of four in vivo passages (P1-P4) of SHIV-B’ whu. Each serial were sacrificed on fourteenth day. Pathological changes of lymph nodes were studied respectively. Results The infected monkeys demonstrated a transient increase of body temperature during the acute stage of infection with all the passages of SHIV. SHIV-B’whu infection was also demonstrated by the pathological findings: focal necrosis in liver, interstitial pneumonia, partially enlarged lymph antrum, diminished lymph follicle, and erythrophagia in lymph nodes. Macrophage positive rates in monkey tissues increased at a uncertain gradient from PI to P4(from about 3.5% to 22%). Conclusion This study provide direct evidence that SHIV-B’whu has the ability to infect Chinese rhesus monkeys, which can present the similar symptom as human being.
