锌和维生素A在哺乳动物体内的几种新陈代谢过程中居重要地位。当此微量营养素一种或二者同时缺乏时,则感觉、生长、脑、造血、免疫、上皮再生和男性生育等生理功能可以失调。除其他原因以外,在肝硬化病人如有锌和/或维生素A缺乏,则可发生这些方面的症状。两种微量营养素密切相关,因此肝硬化患者总是反复表现二者均缺状态。摄入减少、吸收障碍、肝切除术及丢失增加均可为缺乏原因。研究表明,特别是存在门脉系统分流时,病人,以及鼠的门腔分流模型中,
Zinc and vitamin A play an important role in several metabolic processes in mammals. When one or both of these micronutrients are lacking at the same time, physiological functions such as growth, brain, hematopoiesis, immunity, epithelial regeneration, and male fertility can be deranged. Among other things, these symptoms can occur in patients with cirrhosis who have a deficiency of zinc and / or vitamin A. Two kinds of micronutrients are closely related, so patients with liver cirrhosis are always repeated performance of both state. Reduced intake, malabsorption, hepatectomy, and increased loss may all be cause of deficiency. Studies have shown that, especially in the presence of portal system shunt, the patient, as well as the mouse compartment shunt model,
