Noradrenaline content and turnover rate were measured in sympathetically innervated tissues of adult male rats that were fed diets varying in alpha-tocopherol for 10 to 11 weeks. At the end of the feeding period, increasing amounts of vitamin E increased the levels of noradrenaline in liver and white adipose tissue but no differences were observed in heart and interscapular brown adipose tissue. By contrast, increased amounts of dietary vitamin E decreased both the rate constant for the decline of specific activity of noradrenaline with time and the noradrenaline turnover rate in heart and brown adipose tissue. No significant differences were observed in these parameters in liver and white adipose tissue. These results indicate that vitamin E in the diet may affect activity of the sympathetic nervous system.
给成年雄性大鼠喂食α-生育酚含量不同的日粮10至11周后，测量其交感神经支配组织中的去甲肾上腺素含量和周转率。在喂食期结束时，维生素E摄入量增加会使肝脏和白色脂肪组织中的去甲肾上腺素水平升高，但在心脏和肩胛间棕色脂肪组织中未观察到差异。相比之下，日粮中维生素E含量增加会降低心脏和棕色脂肪组织中去甲肾上腺素比活性随时间下降的速率常数以及去甲肾上腺素周转率。在肝脏和白色脂肪组织的这些参数中未观察到显著差异。这些结果表明，日粮中的维生素E可能会影响交感神经系统的活性。
