To study the changes between SOD activity and LPO content in serum of the patients with hepatitis B virus, the methods of xanthine oxidase and thiobarbituric acid were applied to this study.

• 为了研究乙型肝炎患者血清中超氧化物歧化酶(SOD)活性水平、过氧化脂质(LPO)含量及其变化规律，应用黄嘌吟氧化酶法和硫代巴比妥酸法测定了53例乙肝患者血清中SOD与LPO含量，其中急性乙型肝炎(急肝)35例，慢性活动性乙型肝炎(慢活肝)18例。
