The activities of lipid peroxidation processes and enzymes of antioxidant system in the blood of patient with renal failure have been studied. The results demonstrated stimulation of lipid peroxidation processes in blood serum, cellular membranes of erythrocytes and in urine. The study of the antioxidant system discovered the inhibition of various enzymes: superoxide dismutase and peroxidase, inhibiting production of active oxygen forms; transferring and ceruloplasmin as regulators of Fe2+/Fe3+ ratio, glutathione reductase and glutathione peroxidase influencing the ratio of oxidated and reduced glutathione forms and the level of SH-groups. So, determination of lipid peroxidation processes and antioxidant enzymes in blood is the sensitive inform test in diagnostics of chronic renal failure.
对肾衰竭患者血液中脂质过氧化过程及抗氧化系统酶的活性进行了研究。结果表明,血清、红细胞细胞膜及尿液中的脂质过氧化过程受到刺激。对抗氧化系统的研究发现多种酶受到抑制:超氧化物歧化酶和过氧化物酶,它们抑制活性氧形式的产生;转铁蛋白和铜蓝蛋白作为Fe2+/Fe3+比例的调节剂,谷胱甘肽还原酶和谷胱甘肽过氧化物酶影响氧化型和还原型谷胱甘肽形式的比例以及SH基团的水平。因此,测定血液中的脂质过氧化过程和抗氧化酶是慢性肾衰竭诊断中的敏感信息检测方法。
