摘要

该研究以高尿酸血症大鼠模型为对象,来评价扁舵鲣鱼低聚肽(Auxis thazard oligopeptide,ATO)降尿酸功效。结果表明,通过对比模型组、ATO 1.6 g/kg、2.4 g/kg剂量组,发现脏器系数并不存在显著差异。血清黄嘌呤氧化酶(xan-thine oxidase,XOD)的变化趋势为先降后升再缓降,据此可以确定,短时间内肝脏中XOD活性能明显降低。对比模型组可以发现,血清尿素氮、血肌酐指标有所下降,ATO 2.4 g/kg剂量组最为明显,血尿酸含量明显下降,差异有统计学意义(P<0.05)。各试验组的尿酸浓度和尿酸排泄量相比正常组也有明显降低(P<0.05)。依据组织病理学结果可知,通过ATO的应用,能够保护高尿酸血症大鼠的肾脏,但剂效关系尚不明显;尿酸生成因尿酸盐沉积的减少而降低,因而ATO具有一定的降尿酸功效,并且不会产生过多的毒副作用。

Abstract

Hyperuricemia rat model was used to evaluate Auxis thazard oligopeptide (ATO) on lowering uric acid. The results showed that there was no significant difference in organ coefficients between 1.6 g/kg and 2.4 g/kg ATO groups compared with model group. Moreover, serum XOD showed a trend of decreasing first and then increasing, finally declining slowly, which indicated that XOD activity in the liver was significantly decreased in a short term. Besides, serum urea nitrogen and serum creatinine showed a downward trend, the blood uric acid content of 2.4 g/kg ATO group decreased significantly (P<0.05). The uric acid concentration and uric acid excretion in each test group were also significantly lower than those in the normal group (P<0.05). Futhermore, histopathological results showed that ATO had a certain protective effect on the kidney of hyperuricemia rats. However, the dose-effect relationship was not significant. Less urate deposition indicated a decrease in uric acid production to some extent. Therefore, ATO has a certain uric acid lowering effect even though with a little toxic side effects.
