美《医学世界新闻》第20卷第21期(1979年)报道圣路易斯消息:研究人员认为用小剂量阿司匹林防止透析病人血栓,具有重要意义。不过,华盛顿大学研究人员对每天使用半片阿司匹林治疗是否对所有的人都有作用,或更小的剂量是否有同样效果,提出了疑问。华盛顿大学肾脏中心的医学主任哈特(Herschel R.Harter)指出,用阿司匹林预防血栓形成、脑卒中及心脏病发作的大多数临床试验中,每日剂量为2片,有些人每天多达8片。他补充说:“我们认为每天160毫克,长期服用,毒性较小。” The United States, “Medical World News” Volume 20 No. 21 (1979) reported St. Louis News: Researchers believe that the use of low-dose aspirin to prevent dialysis patients with thrombosis, is of great significance. However, researchers at the University of Washington raised questions about whether half-a-day aspirin use is effective for all, or whether smaller doses have the same effect. Herschel R. Harter, director of medicine at the Washington University Center for Nephrology, points out that in most clinical trials of aspirin to prevent thrombosis, stroke, and heart attacks, the daily dose is two and some as many as eight . He added: “We think 160 mg per day, long-term use, less toxic.”
