摘要
研究虫茶粗多酚(crude polyphenols of Insect tea,CPIT)对乙酰氨基酚致小鼠急性肝损伤的预防效果。在诱导肝损伤后,CPIT可以增加小鼠的体质量和减小肝脏质量,降低肝指数。经过CPIT处理后的小鼠较对照组小鼠(肝损伤)血清谷丙转氨酶、谷草转氨酶、乳酸脱氢酶、甘油三酯、血尿素氮含量均下降,而总胆固醇,白蛋白水平则上升。同时经过CPIT处理后,白细胞介素(interleukin,IL)-6、IL-12、肿瘤坏死因子-α和干扰素-γ的水平也较对照组小鼠降低。CPIT还可以上调肿瘤坏死因子-α、锰超氧化物歧化酶、铜锌超氧化物歧化酶、过氧化氢酶、谷胱甘肽过氧化物酶m RNA的表达和下调核转录因子(nuclear factor-κB,NF-κB)、一氧化氮合酶异型、环氧化酶的表达。通过结果可以看出,CPIT具有预防动物体内肝损伤效果。
