众所周知,获得性免疫缺陷综合征(AIDS)的患者,各种机会感染的发生率很高。作者这次用电镜对AIDS 患者的肝组织进行了研究。方法:研究对象是迈阿密大学肝病研究中心的9例AIDS 患者(年龄22～42岁)。作者先用光镜研究了从腹腔镜或经皮肝活检得到的肝组织,然后用2%戊二醛溶液将一部分肝组织迅速固定,再用1%OsO_4固定,作Araldite 包埋,把超薄切片用铀和铅进行双重染色后通过菲利普300电子显微镜观察。结果:光镜观察的结果表明,9例AIDS 患者中慢性活动性肝炎4侧(乙肝病毒引起的2例),出现小肉芽肿的2例,肝硬变、肝纤维化、枯否氏细胞增生的各1例。电镜结果表明,在5例小管网状型(T
It is well-known that patients with Acquired Immunodeficiency Syndrome (AIDS) have a high incidence of various opportunistic infections. The author of electron microscopy of AIDS patients with liver tissue was studied. METHODS: Nine AIDS patients (aged 22-42 years) with Miami University Liver Disease Research Center were enrolled. The author first studied the liver tissue obtained from laparoscopic or percutaneous liver biopsy with light microscope, then quickly fixed a part of liver tissue with 2% glutaraldehyde solution and fixed with 1% OsO_4 for Araldite embedding, The sections were double stained with uranium and lead and observed by a Philips 300 electron microscope. Results: The results of light microscopy showed that in 9 AIDS patients, 4 patients with chronic active hepatitis (2 cases caused by hepatitis B virus), 2 cases with small granuloma, 2 cases with cirrhosis, hepatic fibrosis, Kupffer cell proliferation Of each one case. Electron microscopy results showed that in 5 cases of small tubular reticular (T
