现认为锌是许多代谢过程必需的微量元素。对肝细胞活性具有保护作用，并可防止氧化作用引起的细胞损伤。肝硬化病人常有锌缺乏且与氮代谢异常有关。本文评估了晚期肝硬化伴轻度或隐性脑病病人口服硫酸锌对氨基酸所衍生的尿素的合成的动力学作用。病人与方法两组各8例病人，组织 It is thought that zinc is a necessary trace element for many metabolic processes. It has a protective effect on hepatocyte activity and prevents cell damage caused by oxidation. Patients with cirrhosis often zinc deficiency and abnormal nitrogen metabolism. This article assesses the kinetic effect of oral administration of zinc sulfate on the synthesis of amino acid-derived urea in patients with advanced cirrhosis with mild or latent encephalopathy. Patient and method of two groups of eight patients, organization
