用低硒饲料和该饲料补硒分别喂大鼠,对比观察硒对动物心、肝,肌、胰、肺和肾脏线粗体~(45)Ca摄取及心肌线粒体呼吸的影响。结果表明硒非常显著地刺激此六脏器细胞线粒体钙摄取,其中,对心、肝、肌的刺激强大而稳定;对胰、肺,在温育过程中逐渐增强;对肾则稍差。硒还非常显著地刺激心肌线粒体呼吸功能。提示硒对维持整体线粒体钙运转及心肌线粒体呼吸功能具重要作用。 The rats were fed with low-selenium diet and selenium supplemented with the same diet, and the effects of selenium on the uptake of Ca ~ (45) Ca and myocardial mitochondrial respiration in heart, liver, muscle, pancreas, lung and kidney were observed. The results showed that selenium significantly stimulated mitochondrial calcium uptake in these six organs. Among them, the stimulus to heart, liver and muscle was strong and stable; to pancreas and lung, it gradually increased during the process of incubation; Selenium also very significantly stimulates myocardial mitochondrial respiratory function. Tip Selenium to maintain the overall mitochondrial calcium transport and myocardial mitochondrial respiratory function play an important role.
