现代药物研究起源于19世纪,随着有机化学的发展打下了药物研究的基础。由于疾病是从外部进入器官组织的病原体所引起的,要恢复健康就必须有选择地消灭病原体。故对病原体的认识就导致了新的医疗方法的发展—化疗。化疗既是一种合理的医疗方法,又是一种已被结合进工业组织的理论。Poul Ehrlich发现化学药物对不同组织的吸附力不同。他认为人体神经组织具有对甲基蓝的高度亲和性是因为神经组织具有特定的化学受体。在掌握 Modern drug research originated in the 19th century, with the development of organic chemistry laid the foundation for drug research. Since the disease is caused by pathogens that enter the organs and tissues from the outside, pathogens must be selectively eliminated to restore health. Therefore, the understanding of pathogens has led to the development of new medical methods - chemotherapy. Chemotherapy is both a rational medical approach and a theory that has been incorporated into industrial organizations. Poul Ehrlich found that chemistries have different adsorbability to different tissues. He believes that human neural tissue has a high affinity for methyl blue because of the specific chemical receptors that nerve tissue has. In master
