Which can be used as the body of vitamin B1 coenzyme of many enzymes in the normal human body has an important role in glucose metabolism, it can inhibit the activity of cholinesterase, and choline esterase is an important neurotransmitter, and thus nerve conduction impact; vitamin B2 in the organization by participating in a variety of yellow enzymes constitute a coenzyme, its role in bio-oxidation process in the delivery of hydrogen role in regulating the body's metabolism process; vitamin B6 can also be a variety of enzymes as coenzyme participate in all kinds of amino acid metabolism, promote the absorption of amino acids and protein synthesis, cell growth is necessary for the material, which also promote fat metabolism, involved in neurotransmitter synthesis, hemoglobin synthesis and the impact on the normal reproductive functions such as human body an important metabolic process, Volkswagen Medicine Net: What liver protection effect of vitamin B family?

可作为维生素乙许多酶的辅酶，在正常人体组织中有一个用糖代谢的重要作用，能抑制胆碱酯酶活性，和胆碱脂酶是一个重要的神经递质，神经传导，从而影响；由黄色参与各种酶在组织中维生素B2构成辅酶，其作用在生物氧化氢的作用，调节人体的代谢过程中产程；维生素B6也可以是作为辅酶参与氨基酸代谢的各种酶的品种，促进氨基酸的吸收和蛋白质合成，细胞生长是必要的材料，这也促进脂肪代谢的神经递质合成，血红蛋白合成和参与，如影响人体生殖功能的正常新陈代谢过程中一个重要的，（大众医药网：什么样的维生素B家庭肝脏的保护作用？

Comparing with chicken egg-white lysozyme which is widely used in clinic, hLYZ has many advantages: it is a natural protein in human body, so it is safe and harmless when used as a drug; its bioactivity to kill bacterium is three times higher than chicken egg-white lysozyme, and its thermal stability is much higher, too; it also has many other specific important functions which are not related with its catalysis, such as anti-virus and anti-tumor and improving immunization.

人溶菌酶与目前临床上应用最多的鸡蛋清溶菌酶相比具有以下优势：人溶菌酶是人体内的蛋白，具有天然的相容性，没有毒性和副作用；人溶菌酶比鸡蛋清溶菌酶的杀菌活性高3倍，而且热稳定性也要远高于鸡蛋清溶菌酶；人溶菌酶还有多种特有的与其自身的催化作用无关的理化作用，如抗病毒和抗肿瘤。

It was observed that not only histidine, but also histidine-Co and histidine-Ni could induce and substitute some Cu and Zn from Cu_2Zn_2SOD, eventually influence the activity of this metalloenzyme. Histidine- metal ion complexes have stronger ability than histidine to displace the bound metal ion from SOD. In addition, the amount of foreign metal ion binding to the SOD was less than that of metal ion lost from SOD. It obviously means that there was apoenzyme in the solution.

实验结果表明： Cu2Zn2SOD酶不仅与组氨酸，而且还可以与组氨酸－CoⅡ）和组氨酸－Ni(Ⅱ相互作用，Cu2Zn2SOD酶中的部分Cu和Zn被诱导和置换出来，并相应地影响了酶的活性；组氨酸－金属离子配合物的作用比组氨酸强，酶活性降低也更明显；酶中结合的外来金属离子的量比从酶上被诱导和顶替下来的金属离子的量要少，说明在溶液中有脱辅基酶的存在。

Six and twelve boors after sepsis, leptin levels in liver homogenate were detected by radioimmunoassay serum alanine aminotransferase and 4 enzymes in liver homogenate. myeloperoxidase, glutathin-S-transferase, xanthine oxidase and superoxide dismutase, all related with synthesis of free radicals, detoxication and purine metabolism, were detected by 96 well spectrophotometry. H-E staining was used to examine the histopathologic changes of liver.
