对５０９例门诊查体者进行了ＡＬＴ及ＨＡＶ、ＨＢＶ、ＨＣＶ、ＨＤＶ、ＨＥＶ标志物的检测；并对检测出的肝炎病毒感染者、肝炎患者以及肝炎病毒标志物阴性者（对照组）的血液进行了ＳＯＤ、ＧＳＨ－ＰＸ、ＬＰＯ测定。结果显示：肝炎病毒感染者、肝炎患者血中ＳＯＤ、ＧＳＨ－ＰＸ的含量，均显著低于对照组（Ｐ＜００５）；ＬＰＯ的含量高于对照组（Ｐ＜００５，Ｐ＜００１），当多种肝炎病毒混合感染时血ＳＯＤ、ＧＳＨ－ＰＸ下降、ＬＰＯ增高更明显，其中以ＨＢＶ、ＨＣＶ、ＨＥＶ三重叠感染及复合型肝炎（ＨＢＶ、ＨＣＶ、ＨＤＶ）时更为显著（Ｐ＜００５），提示：肝炎病毒感染者及肝炎患者血ＳＯＤ、ＧＳＨ－ＰＸ均有不同程度降低，ＬＰＯ却有不同程度增高，并与肝损伤有一定的相关性。
The detection of ALT, HAV, HBV, HCV, HDV and HEV markers in 509 outpatients was carried out. The blood samples from hepatitis B virus infected patients, hepatitis patients and hepatitis B virus negative samples (control group) SOD, GSH-PX and LPO were measured. The results showed that the contents of SOD and GSH-PX in the blood of hepatitis virus infected patients and hepatitis patients were significantly lower than those of the control group (P <005), and the content of LPO was higher than that of the control group (P <005, P < 001), when a variety of hepatitis B virus mixed infection, blood SOD, GSH-PX decreased, LPO increased more significantly, including HBV, HCV, HEV triple overlapping infection and hepatitis B (HBV, HCV, HDV) (P <005), suggesting that the serum levels of SOD and GSH-PX in patients with hepatitis B virus infection and hepatitis were decreased to varying degrees, while LPO increased to some extent and had certain correlation with liver injury.
