Abstract: 12周龄雄性大鼠饲缺维生素B6(VB6)缺硒酪蛋白蔗糖基础膳食,3周后按体重把动物分成6组。分别喂饲三种膳食,即基础膳食、基础膳食中补充硒0.25mg/kg的亚硒酸钠或DL-硒蛋氨酸,在此基础上每种膳食又分为补充(2.5μg/g)或不补充盐酸吡哆醇两组。实验期为14周。补V86各组的红细胞和骨骼肌中硒水平和谷胱甘肽过氧化物酶(GSH-Px)活性均显著高于相应缺VB6各组,VB6对饲亚硒酸钠大鼠肝硒和GSH-Px水平没有影响;但当补充硒蛋氨酸时,与补VB6大鼠相比缺VB6大鼠的肝硒水平较高而GSH-Px活性则显著降低。这些研究结果进一步证明,VB6与血浆硒的转运和硒的利用有关,并且可能参与了硒蛋氨酸在肝脏中的代谢过程。
