摘要
维生素A(Vit A)作为人体所必需的一种微量营养素,与机体正常功能维持密切相关。在中国,典型的Vit A缺乏症已很少见,然而不典型缺乏发病率仍较高,其缺乏与人体易患感染性疾病尤其与呼吸道感染密切相关。近年来关于Vit A与感染性疾病关系的研究众多,主要集中在免疫方面。本文就Vit A对免疫及肺部疾病影响进行相关综述。
Vitamin A(Vit A)is a micronutrient that plays an important role in organism,and it is closely related to the maintenance of the normal function of the body.In China,the typical Vit A deficiency has been rare,but the prevalence of atypical lack is still high.Vitamin A deficiency would lead to infectious diseases,particularly respiratory infections.In recent years,there have been many researches on the relationship between Vit A and infectious diseases,most in the aspect of immunity.This review summarizes the effects of Vit A on immunity and the lungs.
