锌是人体重要的微量元素。一系列研究表明锌缺乏与儿童腹泻、肺炎等感染性疾病密切相关,锌代谢的改变在感染患者更明显,并与某些疾病严重程度相关。我国儿童普遍存在缺锌的问题。现就锌的评价方法、锌在免疫方面的作用及可能机制、对某些感染性疾病发病率及病程长短的影响、补锌疗效等方面的研究进展进行综述。
Zinc is an important trace element in the human body. A series of studies have shown that zinc deficiency is closely related to infectious diseases such as childhood diarrhea and pneumonia. Changes in zinc metabolism are more obvious in infected patients and are related to the severity of certain diseases. Zinc deficiency is widespread in children in our country. Now on the zinc evaluation methods, the role of zinc in the immune and possible mechanisms, the incidence of certain infectious diseases and the duration of the disease effects, efficacy of zinc and other aspects of research are reviewed.
