医学发展离不开试验,许多试验又必须在人体上进行,这是医学有别于其他学科的一大特征。在医学发展的漫长历程中,出现了许多具有献身精神的医学家,他们冒着生命危险在自己身上试验,不少人因此致病、致残,甚至献出生命。因此有人说“医学是一门需要献身的科学”。先从2005年诺贝尔医学奖得主之一的巴里.马歇尔说起。马歇尔为证实幽门螺旋杆菌确实能致胃溃疡,1981年,他拿自己做实验,喝下一瓶含有数以亿计的幽门螺旋杆菌培养液。几天后他身上出现了胃溃 The development of medical science can not be separated from the test, and many tests must be carried out on the human body. This is a major feature of medicine different from other disciplines. In the long course of medical development, there have been many dedicated medical scientists who have risked their lives to test themselves. Many people have become sick, maimed and even given lives. Therefore, some people say that “medical science is a science that needs devotion.” Start with Barry Marshall, one of the winners of the 2005 Nobel Prize in Medicine. Marshall confirmed that helicobacter pylori can actually cause stomach ulcers. In 1981, he took his own experiments and drank a bottle containing hundreds of millions of H. pylori broth. A few days later he had a stomach ulcer
