1974年3月,美国揭露了一桩科学上弄虛作假事件。当事人萨默林(W.Summerlin)曾宣称,黑鼠的皮肤移植片经体外培养后,可移植到白鼠身上而不发生免疫排斥反应,长期存活下来。他还宣称,人的皮肤经过4～6个月的组织培养后,移植到其他人身上也可以不被排斥。正当他准备在一次学术会议上报告他对多例烧伤病人应用异体皮肤移植而不发生免疫排斥反应的“辉煌成果”时,他的一名助手发现,萨默林移植到白鼠身上的黑色皮肤移植片竟能被酒精脱色。原来那是伪造的经过染色的皮肤片。此事一经揭露,舆论哗然,许多报刊都称这件丑闻为“美国科学界的水门事件”。 1981年,美国科学界又揭露出一桩在科学实验上作弊的“水门事件”。当事人斯佩克特(M.Spector)是美国康奈尔大学的一名年轻有为的研究生。他的导师雷克(E.Racker)是一位精神病学家,在科学界颇 In March 1974, the United States uncovered a scientific fraud. Party Summelin (W.Summerlin) had claimed that the skin graft of black mice after in vitro culture, can be transplanted to rats without immune rejection, long-term survival. He also claimed that after 4 to 6 months of tissue culture, human skin can be transplanted to other people without being rejected. As he prepares to report at a conference about his “brilliant success” of applying allogeneic skin grafts to many burn patients without immune rejection, one of his aides found that black skin grafts from surling to rats Film can be decolorized by alcohol. It turned out to be a forged stained skin piece. As soon as the incident was revealed, there was an uproar in public opinion. Many newspapers called the scandal “the Watergate incident in the United States of science.” In 1981, the U.S. scientific community uncovered a Watergate incident that cheated on scientific experiments.
