    Abstract:

    Objective: To investigate whether a stable and reliable hyperuricemia model can be established in mice with ICR background by triple modeling method (combined with potassium oxazine, hypoxanthine and 30% yeast paste), and to evaluate the modeling method with positive drug febuxoesta. Methods: The hyperuricemia model of ICR mice was established by using potassium oxazine, hypoxanthine and 30% yeast paste diet, respectively, and the serum uric acid, creatinine, xanthine oxidase (XOD), uric acid oxidase (UOX) and other indicators were detected to evaluate the success of hyperuricemia model.Results: The serum uric acid level of ICR mice was not significantly changed by potassium oxazinate alone, which showed an increasing trend but no significant difference with that of 30% yeast paste diet and hypoxanthine combined groups, while the serum uric acid level in triple administration group was significantly increased at 7 days (P<0.01). After 14 days of dynamic monitoring, blood uric acid level of triple dose induced ICR mice peaked at 7 days. Meanwhile, the activity of XOD enzyme was increased, while that of UOX enzyme was decreased (P<0.001). In addition, triple-dose induced hyperuricemia in ICR mice was sensitive to the positive drug febuxoat, with a significant decrease in blood uric acid levels (P<0.001). Conclusion: The hyperuricemia model of ICR mice can be stably induced by triple administration at 7 days.
