ABSTRACT
【Objective】 To observe the uric acid-lowering effect of 3,4-dihydroxy-5-nitrobenzaldehyde (DHNB) on hyperuricemia models in mice and quails so as to improve the pharmacodynamic validation on hyperuricemia models. 【Methods】 The mouse hyperuricemia animal model was prepared by intraperitoneal injection of potassium oxonate 300 mg/kg; 30 g/(kg·d) yeast powder mixed feed (yeast powder∶feed, 1∶4) was used to prepare the quail hyperuricemia animal model. DHNB, 100 mg/kg, was intraperitoneally injected into the mice 1 hour prior to modeling; DHNB, 100 mg/kg, was intragastrically administered for two days consecutively into the quail hyperuricemia models. Control groups in mice and quails were set up respectively. Biochemical kits were used to detect serum uric acid, aspartate aminotransaminase (AST), alanine aminotransaminase (ALT), creatinine (Cr), and blood urea nitrogen (BUN) in mouse and quail serum. Heart, lung, liver and kidney tissues of mice and quails were stained with HE. 【Results】 The serum uric acid in the mouse and quail hyperuricemia model groups was higher than that in the control group [(277.37±94.89) μmol/L vs. (176.49±44.83) μmol/L, P0.05]. However, it significantly decreased serum uric acid in the quail model of hyperuricemia (313.58±191.87) μmol/L vs. (160.44±49.90)μmol/L, P<0.05]. Administration of DHNB 100 mg/kg one or two times had no effect on the liver and kidney functions of mice and quails, and had no toxicity to the heart, lung, liver or kidney tissues of mice and quails. 【Conclusion】 DHNB has a uric acid-lowering effect on the hyperuricemia quail model, and a single dose that caused the uric acid-lowering effect has no obvious toxicity to mouse or quail viscera. The quail hyperuricemia model is more suitable for the validation of the uric acid-lowering efficacy of DHNB than the mouse hyperuricemia model.
