消化道疾病很容易引起人体内各种微量无素的缺乏。本文着重阐述微量元素锌、铜、硒与消化道疾病的关系。锌缺乏可导致:1.食管粘膜等的鳞状上皮细胞角化异常;2.肠粘膜细胞间境界不清,微绒毛减少;3.细胞内溶酶体增加和网状体、高尔基体的萎缩;4.阻碍乳糜微粒的形成,从而影响肠道吸收甘油三酯;5.含有锌的潘氏细胞(Paneth cell)减少。动物实验(牛)中,铜的缺乏可引起腹泻,此时十二指肠、空肠、回肠粘膜上皮中细胞色素氧化酶(cytochrome oxidase)活性明
Gastrointestinal diseases can easily cause a variety of trace elements in the human body lack of. This article focuses on the relationship between trace elements zinc, copper, selenium and digestive diseases. Lack of zinc can lead to: 1. Squamous epithelial cells of the esophageal mucosa and other abnormal keratinization; 2. Intestinal mucosal cells between the state, microvilli reduced; 3. Lysosomes increased intracellular and mesh, the atrophy of the Golgi apparatus ; 4 hinder the formation of chylomicrons, thereby affecting the intestinal absorption of triglycerides; 5 zinc-containing Paneth cells (Paneth cells) decreased. Animal experiments (cattle), the lack of copper can cause diarrhea, duodenum, jejunum, ileum mucosal epithelium cytochrome oxidase activity
