摘要
目的 观察麻黄水提物对顺铂所致大鼠肝损伤的影响.方法 将40只大鼠按随机数字表法分为空白组、模型组及麻黄水提物低、中、高剂量组,麻黄水提物低、中、高剂量组大鼠灌胃100、200、400 mg/kg麻黄水提物,空白组和模型组灌胃等体积生理盐水,1次/d,连续灌胃10 d.除空白组外,其余各组大鼠于第6天给予顺铂(8 mg/kg)建立大鼠肝损伤模型.观察各组大鼠体重变化,检测各组大鼠血清ALT、AST及肝组织MDA、NO、SOD、GSH水平变化,采用HE染色观察各组大鼠肝组织病理学改变.结果 给予顺铂后第3、5天,麻黄水提物低、中、高剂量组大鼠体重较模型组升高(P<0.05或P<0.01).与模型组比较,麻黄水提物中、高剂量组大鼠血清AST[(328.00±168.00)U/L、(297.00±139.00)U/L比(409.00±364.00)U/L]和ALT[(122.00±76.00)U/L、(97.00±64.00)U/L比(198.00±156.00)U/L]含量减少(P<0.05或P<0.01);麻黄水提物中、高剂量组大鼠肝组织SOD[(34.98±7.40)U/mg、(41.80±8.10)U/mg比(12.70±3.10)U/mg]、GSH[(16.90±1.70)mg/g、(22.70±3.70)mg/g比(9.90±1.30)mg/g]水平升高,MDA[(3.20±0.60)nmol/ml、(2.20±0.30)nmol/ml比(4.30±0.70)nmol/ml]、NO[(0.90±0.10)μmol/L、(0.80±0.20)μmol/L比(1.20±0.30)μmol/L]水平降低(P<0.05或P<0.01).结论 麻黄水提物对顺铂所致的大鼠肝损伤有一定的保护作用.
Abstract
Objective To study the effect of water extract of ephedra on hepatic injury induced by cisplatin in rats. Methods Forty rats were randomly divided into the blank group, model group, and ephedra water extract was divided into the low dose group, medium and high dose group. Ephedra water extract in the low, medium dose group, high dose group were 100, 200, 400 mg/kg. The normal saline of equal volume was used in the blank group and model group, once a day for 10 days. In addition to the blank group, the other groups were given cisplatin (8 mg/kg) on the 6th day to establish the model of liver injury in rats. The changes of body weight, serum ALT, AST and liver MDA, NO, SOD, GSH were detected by biochemical method. The pathological changes of liver tissue were observed by the staining. Results On the 3rd day and 5th day after administration of cisplatin, the body weight of the rats in the low, medium and high dose group were significantly higher than that in the model group (P<0.05 or P<0.01). Compared with the model group, the serum AST (328.00 ± 168.00 U/L, 297.00 ± 139.00 U/L vs. 409.00 ± 364.00 U/L), ALT (122.00 ± 76.00 U/L, 97.00 ± 64.00 U/L vs. 198.00 ± 156.00 U/L) in the medium-, high- dose group significantly decreased (P<0.05 or P<0.01). The content of SOD (34.98 ± 7.40 U/mg, 41.80 ± 8.10 U/mg vs. 12.70 ± 3.10 U/mg), GSH (16.90 ± 1.70 mg/g, 22.70 ± 3.70 mg/g vs. 9.90 ± 1.30 mg/g) in the medium-, high- dose group significantly increased,while the content of MDA (3.20 ± 0.60 nmol/ml, 2.20 ± 0.30 nmol/ml vs. 4.30 ± 0.70 nmol/ml), NO (0.90 ± 0.10 μmol/L, 0.80 ± 0.20 μmol/L vs. 1.20 ± 0.30 μmol/L) significantly decreased (P<0.05 or P<0.01). Conclusion The ephedra water extract can protect the liver injury induced by cisplatin in rats.
