Protective effects and mechanisms of tetramethypyrazine on accelerated anti-GBM antibody nephritis in rats / 中国药理学通报

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
