晚期糖基化终末产物致动脉硬化的研究及药物干预(2)
3.4.3蜂胶研究表明,蜂胶含有大量的黄酮类、萜烯类等化合物。从蜂胶中提取出的黄酮、黄酮醇类化合物就多达30种。蜂胶是公认的天然抗氧化剂,其中的芦丁、维生素E及微量元素硒等物质,具有很强的抗氧化作用,能阻止自由基的氧化损伤。可见多种蜜蜂产品对心血管系统健康的维护都很有裨益。
最近研究表明,除了内生形式的AGEs,饮食来源的AGEs也是一种重要的AGEs生成方式。饮食来源的AGEs促成整个机体的AGEs池。近来体内外的相关研究显示,食源性的AGEs与多种心血管病变的标记物显著相关[12],并暗示限制食源性AGEs有望成为一种干预手段。
综上所述,近年来,国内外关于AGEs的实验动物研究主要集中在糖尿病的并发症上,以糖肾为多,动物模型也以糖尿病大鼠模型为主。国外曾有学者应用氨基胍对实验动物AS模型进行干预,但在临床实验时效果不佳(肾脏代谢快、导致维生素B 在体内缺乏)。所以有必要找个疗效好且副作用小的药物替代氨基胍。吡多胺(PM)是维生素B6的衍生物,可通过抑制氧化应激(自由基清除剂)、俘获羰基化合物抑制AGEs的生成。且其对人体几乎无毒害作用,临床应用前景广阔,特别是与氨基胍联合应用,既增强抑制AGEs生成的作用,又避免了维生素B6缺乏的副作用,效果值得期待。
