Abstract:

Increases of serum uric acid in golden hamsters were induced by the combination of high-purine diet and uric acid inhibitor potassium oxonate. Serum glucose, lipid changes and histopathological changes of kidney were detected, and the effects of high-purine diet on the changes of serum lipids and liver and kidney injury of golden hamster were investigated. The results showed that there was no significant change in the body weight and liver index of golden hamsters with high-purine diet, and the application of 12% yeast and 0.25% adenine combined with 2% potassium oxonate led to a significant increase in serum uric acid level, but the correlation between elevated serum uric acid and blood glucose and lipid metabolism disorders was not strong. Elevated uric acid leads to renal enlargement, significantly increased renal index, and renal pathological injury characteristic of typical hyperuricemia. The golden hamster with human lipid metabolism characteristics have good prospects for the development of animal models of hyperuricemia.

Key words: golden hamster, uric acid, lipid, kidney injury
