最近许多医学家和其他学科的病理学家很注意病毒与癌的关系。根据近十多年来的实验,有些特殊的癌已知道与病毒有密切的关系。而且某种癌组织总是发生异常的细胞分裂,相对地来说,病毒侵入宿主细胞以后,也发生异常的细胞分裂。根据分子生物学的研究,在染色体活动过程中,病毒可成为刺激因素。病毒进入宿主以后,在相当长的时间内,并不活跃(或者不进行繁殖),经过一段潜伏期之后,才发生改变而影响到 Recently, many medical scientists and pathologists in other disciplines have paid attention to the relationship between the virus and cancer. According to experiments in the past more than a decade, some special cancers are known to have a close relationship with the virus. Moreover, certain cancerous tissues always undergo abnormal cell division. In contrast, when the virus invades the host cell, abnormal cell division also occurs. According to the study of molecular biology, the virus can become a stimulatory factor in the course of chromosome activity. After the virus enters the host, it is not active (or propagated) for a long period of time. After a period of incubation, the virus changes and affects
