美被曝拿国民做人体实验 注射癌细胞
美联社2月27日揭露,半个多世纪前,美国政府曾在国内对疾病患者及囚犯开展人体实验,名义上用于研发药物和研究治疗方法.一个生物伦理委员会定于本周召开会议,进一步揭开这些陈年研究项目的细节与全景.
让囚犯吸入流感病毒
美国政府去年10月就1946年至1948年间在危地马拉开展性病人体实验事件道歉.政府官员当时承认,类似实验在美国国内也曾发生十余起.不过,美联社记者查阅医学杂志文章和剪报资料后认定,涉及美国公民的研究实验数量超过40起,主要进行于上世纪40年代至60年代.这些实验项目包括,在康涅狄格州使精神病患者感染肝炎病毒、在马里兰州让囚犯吸入流感病毒、在纽约市一医院向慢性病患者注射癌细胞.不少实验项目由政府资助.一些实验用于研发药物和治疗方法,一些只是为满足好奇心,没有生成实际成果.
这些实验项目类同于先前经媒体公开的“塔斯基吉梅毒研究”.美国卫生部门官员1932年起在亚拉巴马州以免费治疗梅毒为名,召集约600名黑人男子作为实验品,秘密研究梅毒对人体危害.这些梅毒患者实际上未得到充分治疗.这一研究项目1972年经媒体曝光后终止.此前,充当实验品的当事人一直不知情.

Americans had to take to do human trials injections of cancer cells
On February 27, the Associated Press, more than half a century ago, the U.S. government has in the domestic to disease patients and prisoners to carry out the experiments, nominally for drug treatment and research. A bioethics committee held a meeting scheduled for this week, further reveal the aged research project and the details of the view.
Let inmates inhaled flu virus
The U.S. government is in October last year from 1946 to 1948 an apology in Guatemala venereal human trials. Government officials admit that at that time, similar experiments have occurred in the United States more than 10. However, the Associated Press access to medical journal articles and newspaper clippings data are confirmed, the number of research involving a citizen of the United States more than 40, mainly in the 1940 s and 60 s. These experiments include project, make mental patients infected with hepatitis virus in Connecticut, let prisoners to inhale the influenza virus in Maryland, a hospital in New York City to chronic injection in patients with cancer cells. A lot of experimental project funded by the government. Some experiments to develop medicines and treatments, some just to satisfy curiosity, not generate actual results.
These experiments similar projects with the previously by the media "tuskegee syphilis study". U.S. health officials since 1932 in Alabama, free treatment for syphilis, called about 600 black man as experiment, secret research syphilis harm to human body. These patients with syphilis in fact is not fully treatment. This research project in 1972 after the media exposure. Previously, as the experiment have been unaware of the parties.
