Abstract：Objective To observe the preventive effect of alkaline drinking water on hyperuricemia in mice. Methods Sixty male SPF Kunming mice were randomly divided into six groups: pH 7.3, pH 8.0, pH 9.3 intervention groups, in which the mice were given water with pH values of 7.3±0.5, 8.0±0.5 and 9.3±0.6, respectively; the control group, model group and positive drug group ( with 2 g/L allopurinol ) were given double distilled water. Except for the control group, the mice in each group were given yeast by gavage ( 1.5 g/mL ) for 13 days. On the 14th day, the mice were injected with 300 mg/kg potassium oxyzinate by intraperitoneal injection, and then fasted for 1 day. On the 16th day, serum uric acid, creatinine and urea nitrogen were detected, and renal tissues were stained to observe the morphology. The expression levels of neutrophil gelatinase-associated lipocalin ( NGAL ), tissue inhibitor of metalloproteinase 1
