Abstract

Metabolic rate of gerbils was lower than that of mice (35%). We tried to assess the part played by brown adipose tissue in this low level. Mitochondrial respiration (state 4), protein content and cytochrome-oxidase activity of interscapular BAT mitochondria were very low in gerbils compared to mice, whereas in liver and muscle these parameters were not significantly different. Like in fasting animals, the low level of basal energy expenditure of gerbils may be ascribed to low activity of BAT.

摘要

沙鼠的代谢率低于小鼠（低35%）。我们试图评估褐色脂肪组织在这种低代谢水平中所起的作用。与小鼠相比，沙鼠肩胛间褐色脂肪组织线粒体的线粒体呼吸（状态4）、蛋白质含量和细胞色素氧化酶活性非常低，而在肝脏和肌肉中，这些参数没有显著差异。与禁食动物一样，沙鼠基础能量消耗水平较低可能归因于褐色脂肪组织的低活性。
