红茶及其发花红砖茶对高尿酸血症模型小鼠的降尿酸作用
|
摘要
以相同品种的鲜叶加工而成的红茶及其发花红砖茶为原料,在应用氧嗪酸钾成功建立高尿酸血症模型小鼠方法的基础上,将90只KM雄性小鼠按每组10只随机分为正常组、模型组、红茶及发花红砖茶高、中、低剂量组和别嘌呤醇组,连续灌喂14 d,探讨红茶及其发花红砖茶对高尿酸血症模型小鼠的降尿酸作用。结果表明,与模型组相比,给茶各剂量组的体质量、肾脏指数、血尿酸均显著降低(P<0.05),其中发花红砖茶中、高剂量组在降低血尿酸上达到极显著水平(P<0.01);两种茶各剂量组的血尿素氮、血肌酐也均极显著降低(P<0.01),且中、高剂量组的尿尿素氮极显著升高(P<0.01),高剂量组的尿尿酸极显著升高(P<0.01);除红茶低剂量组尿肌酐水平显著升高(P<0.05)之外,其他给茶组的尿肌酐均达到极显著升高(P<0.01);除发花红砖茶中剂量组显著降低黄嘌呤氧化酶和腺苷脱氨酶活性(P<0.05)之外,红茶中剂量组及两种茶高剂量组均能极显著降低这两种酶的活性(P<0.01)。结果表明,红茶及发花红砖茶均可减少尿酸的产生,且发花红砖茶高剂量组在降低血尿酸与升高尿尿酸、尿尿素氮、尿肌酐方面优于红茶,其机制有待进一步探究。
Based on the successful establishment of hyperuricemia model mice by potassium oxonate, black tea and its flower black brick tea made from the same fresh leaves were used to investigate their effects on lowering uric acid in hyperuricemic mice. In the study, ninety KM male mice were randomly divided into nine groups(10 mices for each group) including the normal group, the model group, the black tea-treated groups(high dose, middle dose, lowdose), its flower brick tea-treated groups(high dose, middle dose, low dose) and the allopurinol group. Then all mice were orally administrated for fourteen days. The results showed that compared with the model group, the levels of weight, kidney index and serum uric acid in tea-treated groups were significantly decreased(P<0.05). Moreover, the high-dose group of flower black brick tea had extremely significant reduction in blood uric acid(P<0.01). Blood urea nitrogen and serum creatinine also decreased significantly in tea-treated groups(P<0.01). The levels of urine urea nitrogen in the middle and high dose groups increased significantly(P<0.01), and the levels of urine uric acid in the high dose groups increased significantly(P<0.01). The levels of urine creatinine were significantly increased in the tea-treated groups(P<0.01) except the low-dose black tea group which showed an opposite trend(P<0.05). The middle dose group of flower black brick tea significantly decreased the activities of xanthine oxidase and adenosine deaminase(P<0.05). The middle dose group of black tea and both high dose groups all highly significantly reduced the activities of these two enzymes(P<0.01). These results showed that black tea and flower black brick tea could reduce the production of uric acid, and the high-dose flower black brick tea group was superior to black tea in lowering blood uric acid and increasing uric acid, urine urea nitrogen, and urine creatinine. The mechanism remains to be further explored.
