Abstract

  • 1.

    1. The metabolism of (U-14C) glucose has been studied in isolated muscle from the reptile Uromastix hardwickii.

  • 2.

    2. The metabolism of glucose was shown to be qualitatively similar to that found in isolated rat diaphragm muscle but the rate of metabolism was significantly reduced.

  • 3.

    3. The influence of lowering the temperature of incubation manifested itself both in the mammalian and reptilian muscle in lowering the rate of glucose catabolism, whereas the effect on glucose incorporation into glycogen and oligosaccharides was not reduced.

  • 4.

    4. The reptile muscle showed that there was an increase in the relative concentration of 14C-maltose accumulating at lower temperature and possible interpretations of this data are discussed.

温度对离体爬行动物和哺乳动物肌肉葡萄糖代谢影响的比较研究
1.1. (U-14C)葡萄糖的代谢已经在爬行动物Uromastix hardwicki的分离肌肉中进行了研究。葡萄糖的代谢与离体大鼠膈肌的代谢在质量上相似,但代谢速率明显降低。降低孵育温度对哺乳动物和爬行动物肌肉的影响均表现为降低葡萄糖分解代谢速率,而对葡萄糖并入糖原和低聚糖的影响不降低。爬行动物的肌肉显示,在较低的温度下,14c -麦芽糖的相对浓度增加,并讨论了对这一数据的可能解释。
