Abstract: | OBJECTIVE Di.E and Gpm.E were separately extracted from two kinds of traditional Chinese medicine.The aim of this research is to investigate the combined anti-hyperuricemia effect of Di.E and Gpm.E on hyperuricemia rats induced by high-purine diet,and to study the underlying mechanism.METHODS Sprague Dawley(SD)rats were divided into some groups according to their serum uric acid(UA),the normal control group received standard diet,while others were fed with high-purine diet.After the success of modeling,SD rats were divided into 5groups according to UA:normal control group,model control group,Di.E and Gpm.E(high,middle,low dosages).The treatment groups were simultaneously orally administered.Two days before the last administration,the urine N-acetyl beta-D Glucosaminidase(NAG),Lysozyme(LYS)activity were separately detected using the urine collected from metabolic cage for 24 h.After the last administration,the blood was taken from postcava to detect the level:① The related indexes of liver and kidney function:the serum UA,blood urea nitrogen(BUN),creatinine(CR),alanine aminotransferase(ALT);② The uric acid metabolism related enzymes:the serum and liver xanthine oxidase(XOD),adenosine deaminase(ADA),guanine deaminase(GD),xanthine dehydrogenase(XDH)activity;③ Fibrosis related indexes of renal tissue:connective tissue growth factor(CTGF),monocyte chemotactic protein-1(MCP-1),TGF-β1,TNF-α,NF-κB levels.RESULTS Di.E and Gpm.E(high,middle dosages)could markedly reduce the serum UA level significantly,also can decrease XOD,ADA,TNF-α,MCP-1,NF-κB activity significantly.CONCLUSION The results show that Di.E and Gpm.E can decrease the serum UA level significantly,improve the liver and kidney function and slow down the process of renal fibrosis;the therapeutic effects may be related to their inhibition of XOD,ADA activity. |
