The effect of the RoseOx drug on rat liver mitochondrial lipids free-radical oxidation in vivo was studied. During the period of 14 days 50 mG/kg per body weight of RoseOx was added to the diet of normal rats each day. Free radical oxidation in liver mitochondrial fraction was determined by the help of a chemiluminescence method. Four kinetic The RoseOx addition to the usual diet led for free radical oxidation braking in mitochondrial fraction of liver as was shown. The RoseOx antioxidizing effect was stipulated by availability of carnosic acid as a supplement. One of the mechanism of the caronosic acid antioxidizing action could be its participation in LFRO reactions breaking by its OH-groups. Carnosic acid contains OH-groups in its molecule as well as a vitamin E for example. So, the mechanism of carnosic acid antioxidizing action is probably similar to vitamin E action in lipid free radical oxidation reactions.
研究了RoseOx药物对大鼠肝脏线粒体脂质体内自由基氧化的影响。在14天的时间里,每天向正常大鼠的饮食中添加每体重50毫克/千克的RoseOx。借助化学发光法测定肝脏线粒体部分的自由基氧化。如所示,在常规饮食中添加RoseOx导致肝脏线粒体部分的自由基氧化受到抑制。RoseOx的抗氧化作用是由肌醇酸作为补充剂的存在所规定的。肌醇酸抗氧化作用的机制之一可能是其通过羟基参与LFRO反应的中断。例如,肌醇酸分子中含有羟基以及维生素E。因此,肌醇酸抗氧化作用的机制可能类似于维生素E在脂质自由基氧化反应中的作用。
