锌作为一种非常重要的营养素正日益得到全世界营养学界和医学界的公认,这方面的研究工作已广泛展开,仅1984～1985年所发表的有关论文就有2500篇。锌广泛地存在于微生物、植物和动物体中,是包括人在内的所有生物的必需微量元素,具有很重要的营养功用,与生物的核酸和蛋白质代谢密切相关,并可促进生长发育,保持视力和味觉功能,提高机体的免疫能力,促进创伤愈合。大量的临床和实验研究表明,锌与创伤愈合密切相关。创伤、手术、烧伤后,机体处于应激状态,需锌量增加,出血、渗出及尿中锌丢失增多,摄入量减少及吸收障碍,均可使体内锌减少。血清锌是反映短期内锌代谢的敏感指标之一,创伤后血清锌迅速下降,一般1～2天降到最低水平。多数病人在两周左右恢复正常,重症病人恢复时间延 As a very important nutrient of zinc, zinc is increasingly recognized by nutritionists and medical professionals all over the world. Research work in this area has been extensively carried out. There are about 2500 related papers published in 1984 ~ 1985 alone. Zinc is widely present in microorganisms, plants and animals and is an essential trace element for all living things, including humans. It has important nutritional functions and is closely related to biological nucleic acid and protein metabolism and promotes growth and development Vision and taste function, improve the body’s immune capacity and promote wound healing. A large number of clinical and experimental studies have shown that zinc and wound healing are closely related. Trauma, surgery, burns, the body is in stress, the need for zinc increased, bleeding, exudation and urine zinc loss increased, reduced intake and absorption disorders, can reduce the body of zinc. Serum zinc is one of the sensitive indicators of short-term zinc metabolism, serum zinc rapidly decreased after trauma, usually 1 to 2 days to a minimum level. Most patients return to normal in about two weeks, severe patient recovery time delay
