通过向培养基中加入黄嘌呤和黄嘌呤氧化酶造成心肌细胞的氧自由基损伤,观察了微量元素Zn的抗氧化损伤作用。实验分为①对照组:MEM+20%小牛血清;②XOD组:对照组加黄嘌呤0.42mM和黄嘌呤氧化酶5.3nM;
By adding xanthine and xanthine oxidase to the culture medium, oxygen free radical damage of myocardial cells was observed, and the anti-oxidative damage of trace element Zn was observed. The experiment was divided into ① control group: MEM + 20% calf serum; ②XOD group: the control group added xanthine 0.42mM and xanthine oxidase 5.3nM;
