【摘要】 目的　探讨川芎嗪 (TMP)对大鼠加速型抗肾小球基底膜 (GBM )抗体肾炎的保护作用及其机制。方法　建立大鼠加速型抗GBM抗体肾炎模型 ,给药组于造模前 1dip给予TMP 12 0mg·kg-1·d-1,连续 15d。于造模后d 1、3、5、7、10、14测 2 4h尿蛋白含量 ;并于d 7,14分两批处死大鼠 ,测定血清尿素氮 (BUN)、肌酐 (Scr)含量 ,制备肾皮质胞浆、线粒体 ,观察其脂质过氧化产物丙二醛 (MDA)含量、谷胱甘肽过氧化物酶 (GSH Px)、过氧化氢酶 (Cat)、超氧化物歧化酶(SOD)的活性变化。结果　川芎嗪给药组与模型组比较 ,尿蛋白含量降低 (P <0 0 1) ;14dBUN、Scr含量减少 (P <0 0 1) ;胞浆、线粒体GSH Px、Cat、SOD活性均增加 (P <0 0 5 ,P <0 0 1)而MDA含量降低 (P <0 0 5 )。结论　TMP对大鼠加速型抗GBM抗体肾炎有保护作用 ,其机制可能与抗氧化损伤有关。更多还原

【Abstract】 AIM To investigate the protective effects and mechanisms of TMP on accelerated anti-glomerulus basement membrane(GBM) antibody nephritis of rats. METHODS Model of accelerated anti-GBM nephritis was established in rats and TMP was administrated 120 mg·kg -1 ·d -1 by ip since the day before the model established, consecutively for 15 days. Content of 24h urine protein was detected after model established and rats were killed on d 7 and d 14. Contents of blood urine nitrogen (BUN) and serum creatinine (SCr) were detected. Renal cortex cytoplasm and mitochondria were produced and change of content of lipid peroxidation products malondialdehyde(MDA), activities of glutathione peroxidase(GSH-Px) and catalase(CAT) and superoxide dismutase(SOD) were investigated. RESULTS Compared with model group, TMP group showed significant inhibition in changes of proteinuria and BUN, SCr(P<0.01) on d 14 and significant increase in activity of GSH-Px, Cat, SOD (P<0.05,P<0.01), while content of MDA decreased in both cytoplasm and mitochondria(P<0.05). CONCLUSION TMP has protective effects against accelerated anti-GBM antibody nephritis in rats via anti-oxidation activity.-更多还原
