摘要 目的探讨白术多糖对颅脑外伤继发性脑组织水肿的影响及其机制。方法采用自由落体撞击模型,大鼠随机分为假手术组、模型组、蒸馏水组(溶剂对照)及白术多糖组,每组再根据伤后不同生存时间随机分为3个亚组。取各组动物伤灶区脑组织,分别检测其含水量和诱导型一氧化氮合酶(iNOS)活性。结果模型组、蒸馏水组及白术多糖组各时间点脑组织含水量均较假手术组明显增加(P<0.01),但白术多糖组各时间点含水量均显著低于模型组及蒸馏水组(P<0.01)。模型组、蒸馏水组及白术多糖组各时间点脑组织iNOS活性均较假手术组明显升高(P<0.01),但白术多糖组各时间点iNOS活性均显著低于模型组及蒸馏水组(P<0.01)。结论白术多糖可能通过下调伤灶区iNOS的表达,而减轻创伤性脑损伤后继发性脑水肿的程度。
