获得性免疫缺陷综合征(AIDS)是近年才出现的在同性恋、静脉给药者和受血者等人群中流行的一组疾病。其特征包括卡氏肺囊虫病、巨细胞病毒和其它机会感染、自身免疫现象、全身性淋巴结病、淋巴瘤和卡波齐氏肉瘤(KS)等。倘缺乏KS和机会感染证据,但具有上述其它特征者则称为AIDS相关综合征(ARC)。AIDS相关的淋巴结病属于淋巴瘤前期增生性疾病之一。目前关于其细胞遗传学资料尚不多见。因而,作者研究了该类患者的染色体改变,同时还测定了 Acquired immunodeficiency syndrome (AIDS) is a group of diseases that have emerged only recently in the population of homosexuals, intravenous donors and recipients. Features include Pneumocystis carinii, cytomegalovirus and other opportunistic infections, autoimmunity, systemic lymphadenopathy, lymphomas and Kaposi’s sarcoma (KS), among others. In the absence of evidence of KS and opportunistic infections, those with these other characteristics are referred to as AIDS-related complex (ARC). AIDS-related lymphadenopathy is one of the pre-proliferative diseases of lymphoma. At present, there is not much information on its cytogenetics. Thus, the authors studied chromosomal changes in this group of patients and also determined
