摘　　要：为探讨甘草炮制雷公藤降低其肝毒性的作用,动物实验评价炮制前后雷公藤对肝脏的毒性,观察空白组、雷公藤组、甘草炮制雷公藤组肝组织病理切片、血清生化指标及细胞炎症因子的差异。大鼠肝组织病理切片显示雷公藤组肝组织损伤明显,炮制后肝组织未见明显损伤;雷公藤组与空白组比较AST,ALT,CRE升高(P<0.01),UREA升高(P<0.05),ALB降低(P<0.01);甘草炮制雷公藤组与雷公藤组比较AST,ALT,CRE,UREA降低(P<0.01),ALB升高(P<0.01)。炎症因子检测结果显示雷公藤组与空白组比较IL-1β,IL-6,TNF-α显著升高(P<0.01);甘草炮制雷公藤组与雷公藤组比较IL-1β,IL-6,TNF-α显著降低(P<0.01)。甘草炮制雷公藤可有效降低雷公藤肝毒性,减轻雷公藤导致的肝损伤。该实验可为雷公藤合理制用提供参考,同时为甘草炮制雷公藤降低其肝毒性研究提供数据支持。To explore the effect of the licorice-processed Tripterygium wilfordii on reducing the liver toxicity. In animal experi- ments, the liver toxicity of T. wilfordii was evaluated both before and after processing, and the differences in liver tissue biopsy, serum biochemical indexes and inflammatory cell factor among blank group, T. wilfordii group and licorice-processed T. wilfordii group were observed. Liver tissue biopsy results showed that liver tissue injury was obvious in T. wilfordii group, and no obvious injury was found in licorice-processed T. wilfordii group. As compared with the blank group, the levels of AST, ALT and CRE were significantly in- creased （ P 〈 0.01 ） , UREA was increased （ P 〈 0. 05 ） , and ALB level was significantly decreased （ P 〈 0.01 ） in the T. wilfordii group. As compared with T. wilfordii group, the levels of AST, ALT, CRE, and UREA were decreased （P 〈0.01 ）, while ALB was increased （P 〈 0. 01 ） in the licorice-processed T. wilfordii group. The results of inflammatory factors in rats showed that the levels of IL-1β, IL-6, and TNF-α in T. wilfordii group were significantly higher than those in blank group （P 〈0. 01 ） ; the levels of IL-1β, IL- 6, and TNF-α in licorice-processed T. wilfordii group were significantly lower than those in T. wilfordii group （P 〈0.01 ）. Overall,licorice processing of T. wilfordii can effectively reduce the liver toxicity and reduce the liver injury caused by T. wilfordii. The experi- ment can provide reference for the clinical rational use of the T. wilfordii, and provide data support for the studies on reducing the liver toxicity of T. wilfordii by licorice processing.
