谷维素（oryzanol）是米糠中重要的活性物质之一。C57BL/6小鼠连续饮用1.0%葡聚糖硫酸钠（dextran sulphate sodium,DSS）12 d,用以建立溃疡性结肠炎模型,评估谷维素的抗炎作用及其分子机理研究。结果发现:谷维素组小鼠能明显缓解DSS诱导的结肠炎症,小鼠肠壁厚度、结肠长度、结肠重量、炎症细胞浸润、疾病活动指数（disease active index,DAI）等病理指标明显改变;谷维素也能明显改善结肠组织中炎症损伤重要生化指标如髓过氧化物酶（myeloperoxidase,MPO）和丙二醛（malondialdehyde,MDA）的含量,同时减少血浆中亚硝酸盐的含量;RT-q PCR技术分析发现结肠组织炎症因子TNF-α、IFN-γ、IL-1和IL-6...

Oryzanol is one of the important active substances in rice bran. A mouse model of ulcerative colitis was established by feeding C57BL/6 mice continuously with 1.0% sulphate sodium D (DSS), and the anti-inflammatory effect of oryzanol and its molecular mechanism were evaluated. The results showed that the symptoms of DSS-induced colitis in the mice from oryzanol group were significantly alleviated. The thickness of bowel wall, colon length, colon weight, inflammatory cell infiltration, disease activity index (DAI) and other important pathologica...
