加味四物四藤汤不同提取物对大鼠血尿酸及黄嘌呤氧化酶的影响

摘要

Objective To explore the effects of different extracts of modified Siwu Siteng Decoction (TFT-Ⅰ, TFT-Ⅱ) on rat models with hyperuricemia. Methods Rat model with hyperuricemia was induced by hypoxanthine and oxonic acid potassium salt. Seventy rats were randomly divided into 7 groups:normal group, model group, allopurinol group, TFT-Ⅰ high and low dose groups, TFT-Ⅱhigh and low dose groups. Each dose group was given lavage with related medicine, and blank group and model group were given lavage with distilled water for one week, respectively. Uric acid in serum (SUA) was measured through fully automatic biochemical analyzer, and xanthine oxidase (XOD) activity in serum and liver tissue was measured through colorimetric method. Results Compared with model group, TFT-Ⅰ and TFT-Ⅱ high dose groups significantly reduced the level of SUA, serum and liver XOD activity (P<0.05), with significant statistical difference between the two groups (P<0.05). TFT-Ⅰ and TFT-Ⅱ low dose groups had no significant effects on SUA, and XOD activity in serum and liver (P>0.05). Conclusion Alcohol soluble ingredients of astragalus membranaceus and Siwu decoction in modified Siwu Siteng Decoction can effectively reduce the level of blood uric acid.%目的：探讨加味四物四藤汤中两种不同工艺提取物(TFT-Ⅰ、TFT-Ⅱ)和复方中黄芪对高尿酸血症作用的强度差异。方法采用次黄嘌呤合并氧嗪酸钾盐诱导造成高尿酸血症模型。70只大鼠随机分为空白组、模型组、别嘌呤醇组、TFT-Ⅰ低剂量组、TFT-Ⅰ高剂量组、TFT-Ⅱ低剂量组、TFT-Ⅱ高剂量组,各给药组予相应药物灌胃,空白组和模型组予等量蒸馏水灌胃,每日1次,连续给药7d。采用全自动生化分析仪测定大鼠血清尿酸(SUA)水平,采用比色法测定大鼠血清、肝组织黄嘌呤氧化酶(XOD)活性。结果与模型组比较,TFT-Ⅰ、TFT-Ⅱ高剂量组可显著降低大鼠血清SUA水平及血清、肝组织XOD活性(P＜0.05),且2组比较差异有统计学意义(P＜0.05)；TFT-Ⅰ、TFT-Ⅱ低剂量对上述炎性因子影响差异无统计学意义(P＞0.05)。结论加味四物四藤汤中黄芪和四物汤的醇溶性成分能有效降低SUA水平。
