自1882年郭霍氏发现了结核杆菌,证明结核杆菌是结核病的病原,很多科学家就致力于化学治疗的研究,大家企图能找到一种药品,应用到人体后,它能杀死结核菌。这种药物对细菌直接作用的观点,在巴甫洛夫学说的批判之下,已证明这一观点是完全错误的。有很多药品,在试管内抑菌或杀菌的效力很高,但应用到人体后,却并不理想;有许多药品,试管内抑菌破杀菌的力量很微弱,但却能治好疾病。这许多事实,说明药物治病的作用,不单 Since 1868, Guo Huo found Mycobacterium tuberculosis, that Mycobacterium tuberculosis is the pathogen of tuberculosis, many scientists are committed to the study of chemotherapy, we attempt to find a drug, applied to the human body, it can kill TB. The viewpoint that this medicine acts directly on bacteria, under the pagination of Pavlov’s doctrine, has proved that this view is totally wrong. There are many drugs in the test tube bacteriostatic or bactericidal effect is very high, but after applied to the human body, but not ideal; there are many drugs, in vitro bacteriostatic bacteria kill the power is very weak, but it can cure the disease. This fact shows that the role of medical treatment is not unique
