黄正良氏撰文介绍了近年国内外研究锌的概况。锌对机体的代谢和生命有着重要作用,与多种疾病的发病关系密切,对延缓衰老具有特殊功能。现知人体内有80多种酶活性与锌有关,细胞中锌的水平通过对含锌酶活性调节来维持机体生理过程。缺锌可导致性腺变性或机能紊乱;孕妇缺锌引起大脑胚胎发育不良;青少年缺锌引起性成熟障碍。缺锌可间接抑制免疫功能。机体含锌量过多或缺锌均易发生肿瘤。锌可减少胃酸分泌,抑制胃分泌液中碳酸酐 Huang Zhengliang’s article describes the general situation of research on zinc at home and abroad in recent years. Zinc plays an important role in the body’s metabolism and life. It is closely related to the pathogenesis of various diseases and has special functions for delaying aging. It is known that more than 80 enzyme activities in the human body are related to zinc. The level of zinc in cells maintains physiological processes of the body by regulating the activity of zinc-containing enzymes. Zinc deficiency can lead to degeneration or dysfunction of the gonad; zinc deficiency in pregnant women causes embryonic dysplasia of the brain; zinc deficiency in adolescents causes sexual maturation disorders. Zinc deficiency can indirectly suppress immune function. Excessive body zinc or zinc deficiency are prone to tumors. Zinc can reduce gastric acid secretion and inhibit carbonic anhydride in gastric secretion
