磺胺药及抗菌素的发现是化疗药物的两个主要发展阶段,对细菌性疾病是确有疗效的,但对病毒病却无能为力。这是因为病毒借侵入并夺取宿主细胞的遗传调控系统而繁殖,不受一般药物的作用。人们早已知道一种病毒能部分地或完全地干扰或抑制另一种病毒在同一宿主细胞内的生长繁殖。已知有几十种互相干扰的病毒系统。但病毒干扰 The discovery of sulfa drugs and antibiotics is the two major stages of chemotherapy drugs, is indeed a curative effect on bacterial diseases, but can not do anything about the virus disease. This is because the virus invades and seizes the host cell’s genetic control system to reproduce, free from the general drug effect. It has long been known that a virus can partially or completely interfere with or inhibit the growth and reproduction of another virus within the same host cell. There are dozens of virus systems that interfere with each other. But the virus interferes
