目的 探索酶学生物标志物精氨酸酶Ⅰ（ArginaseⅠ，ArgⅠ）、α-谷胱甘肽S转移酶（α-glutathione-S-transferase，α-GST）、谷胱苷肽 脱氢酶（Glutamic dehydrogenase，GLDH）和嘌呤核苷磷酸酶（purine nucleoside phosphorlyase，PNP）作为吴茱萸致肝损伤早期敏感指标的可能性。方法 取KM小鼠，随 机分为正常组和吴茱萸组，吴茱萸组连续28 d灌胃给予吴茱萸30 g·kg-1·d-1，正常组灌服等体积蒸馏水；取Wistar大鼠，随机分为正常组和吴茱萸组，吴茱萸组连续28 d 灌胃给予吴茱萸 20 g·kg-1·d-1，正常组灌服等体积蒸馏水，各组均于给药后不同时间点取血及肝组织。全自动生化分析仪检测动物血清生化指标：丙氨酸氨基转移酶 （ALT）、天门冬氨酸氨基转移酶（AST）和总胆红素（TB）含量，ELISA法检测血清中ArgⅠ、α-GST、GLDH和PNP的含量。HE染色，光镜观察肝组织病理形态学变化。结果 小鼠实验中，与同时间点对照组相比，吴茱萸组ALT于给药21 d和28 d显著性升高（P ＜ 0.05或P ＜ 0.01），肝组织形态学检查仅见个别小鼠的肝细胞坏死。吴茱萸组血清 生物标志物ArgⅠ、α-GST和PNP于7 d起明显升高，GLDH于14 d起明显升高（P ＜ 0.05或P ＜ 0.01），均持续至28 d。大鼠实验中，与同时间点正常组比较，吴茱萸组常规 生化指标均无明显变化，肝组织形态学检查仅极少数动物见肝细胞坏死，吴茱萸组血清生物标志物ArgⅠ、GLDH和PNP于7 d起明显升高，α-GST于14 d起明显升高（P ＜ 0.05，P ＜ 0.01），均持续至28 d。结论 血清ArgⅠ、α-GST、GLDH和PNP可作为吴茱萸致肝损伤的早期敏感酶学生物标志物。

Objective To investigate the possibility of taking serum enzyme biomarkers of arginaseⅠ（ArgⅠ），α-glutathione-S- transferase（α-GST），glutamic dehydrogenase（GLDH） and purine nucleoside phosphorlyase（PNP）as the early sensitive indexes of liver injury caused by the decoction of Fructus Euodiae. Methods KM mice were randomly divided into Fructus Euodiae group and normal control group，which were administrated respectively with Euodiae Fructus decoction at the dose of 30g crude drug/kg daily or equal volume of distilled water by gavage for consecutive 28 days. At the same time，Wistar rats were also randomly divided into Fructus Euodiae group and normal control group，which were administrated respectively with Euodiae Fructus decoction at the dose of 20 g crude drug/kg daily or equal volume of distilled water by gavage for consecutive 28 days. Blood samples and liver tissue were taken from the mice and rats at different time points. The activities of serum alanine aminotransferase（ALT），aspartate aminotransferase（AST） and the concentration of total bilirubin（TB）were determined by automatic biochemical analyzer. The contents of serum Arg-1，α-GST，GLDH and PNP were detected by ELISA. Liver tissue was stained by HE，and then the hepatic pathological changes were observed under light microscope. Results In mice experiment，the activity of ALT was significantly increased on day 21 and 28（P＜0.01 compared with that in the control group） in Fructus Euodiae group. Histological examination showed that few mice developed into focal liver cell necrosis. The contents of serum Arg-1，α-GST and PNP were increased obviously from day 7 and the content of serum GLDH was increased obviously from day 14 in Fructus Euodiae group（P＜ 0.05 or P＜ 0.01），and the changes of Arg-1，α-GST，GLDH and PNP continued till day 28. In rat experiment，the activities of ALT，AST and the concentration of TB showed no obvious changes. Focal liver cell necrosis could be observed occasionally in the liver tissue. The contents of serum Arg-1，GLDH and PNP were increased obviously from day 7 and the content of serum α-GST was increased obviously from day 14（P＜ 0.05 or P＜ 0.01） till day 28 in Fructus Euodiae group. Conclusion Serum ArgⅠ，α-GST，GLDH and PNP might be used as the early sensitive biomarkers of the liver injury caused by Euodiae Fructus.
