硒是人体必需的微量元素。本文从硒和病毒毒力、硒和病毒遗传学以及硒和病毒疾病等三方面阐述了硒和病毒之间的密切关系。动物实验显示 :缺硒能加重柯萨奇病毒心脏毒株引起的心脏损害 ,且发现维生素 E缺乏时也产生同样效果 ;通过改变宿主的饮食类型可使良性病毒株转变成毒性株。但到目前为止 ,确切的机制仍不清楚
Selenium is an essential trace element of the human body. This article elaborates the close relationship between selenium and virus from the aspects of selenium and virus virulence, selenium and virus genetics and selenium and virus diseases. Animal experiments show that selenium deficiency can aggravate cardiac damage caused by Coxsackie virus strains and also found the same effect when vitamin E deficiency; by changing the diet of the host, benign strains can be transformed into virulent strains. But so far the exact mechanism remains unclear
