获得性免疫缺陷综合征(AIDS)是一种新认识而病因不明的疾病,以细胞免疫功能失调而在过去健康状况良好的人群中出现条件致病性感染和不常见的肿瘤(特别是Kaposi 氏肉瘤)为特征。自1981年美国首次报道本病以来,其他许多国家都陆续报道了类似的病例,已引起人们的高度重视,不少国家还成立了 AIDS 专题研究组。美国已把本病列为重点研究项目。本文就国外对此病的研究近况简扼综述如下。 Acquired Immune Deficiency Syndrome (AIDS) is a newly recognized and unknown etiology of disease, with cellular immune dysfunction in the past in good health conditions in people with opportunistic pathogenic and unusual tumors (especially Kaposi’s Sarcoma). Since the first report of the disease in 1981 in the United States, many other countries have successively reported similar cases and have drawn great attention from people. Many countries have also set up special AIDS research groups. The United States has the disease as a key research project. This article on the status of foreign research on the disease briefly outlined below.
