In Eliot Marshall's News & Comment article "South Africa blocks AAAS visit" (29 Apr., p. 595), the National Medical and Dental Association was mistakenly named as being among the 17 organizations banned by the South African government on 24 February 1988. Among the organizations that were banned were the South African Trade Unions, the United Democratic Front, the Detainees' Support Committee, and the Detainees' Parents Support Committee.
在艾略特·马歇尔的新闻与评论文章《南非阻止美国科学促进会访问》(4月29日,第595页)中,全国医学与牙科学会被错误地列为1988年2月24日被南非政府禁止的17个组织之一。被禁止的组织包括南非工会、联合民主阵线、被拘留者支持委员会和被拘留者家长支持委员会。
