据发达国家最近的不完全统计,病毒致病约占整个发病率的60%,而病菌感染的发病率仅达15%.由于病毒对人类、动物、植物的广泛影响,研制抗病毒药物势在必行.本文概述了二十年来这方面的研究和应用,讨论了病毒化学治疗遇到的一些新问题.一、抗病毒药物的筛选病毒是寄生细胞内携带自身复制再生的全部遗传信息的最小生物结构.它由脱氧核酸DNA或核酸RNA包绕一层蛋白构成,少数还有脂或多糖外壳.通过同宿主细胞膜特异性缔合,病毒选择性感染特定器官组织.
According to the recent incomplete statistics of developed countries, the incidence of viruses accounts for about 60% of the overall incidence, while the incidence of germs is only 15%. Because of the widespread influence of viruses on humans, animals and plants, the development of antiviral drugs is in the ascendant It is imperative.This paper outlines the research and application in this area over the past two decades and discusses some new problems encountered in virus chemotherapies.First, screening of antiviral drugs is the smallest of all genetic information in parasitic cells carrying self-replicating regeneration Biological structure. It consists of a layer of protein surrounded by deoxyribonucleic acid DNA or nucleic acid RNA, and a few also lipid or polysaccharide shells. The virus selectively infects specific organs by specific association with the host cell membrane.
