| 中文摘要: |
| 中缅树鼩(Tupaia belangeri)为东洋界特有小型哺乳动物。本研究测定了中缅树鼩冷驯化实验组(7d、14d、21d、28d)与对照组(0d)中肝线粒体蛋白含量、呼吸状态Ⅲ和状态Ⅳ的变化,探讨中缅树鼩对不同冷环境的适应情况以及肝产热的机理。结果表明,在冷驯化条件下,中缅树鼩产热显著增加,与对照组相比,实验组肝总蛋白含量、肝线粒体蛋白含量、呼吸状态Ⅲ和状态Ⅳ有着显著的提高,在28d后分别增加了39.9%、39.3%、84.9%、181.1%,因此,肝在中缅树鼩冷适应产热过程中具有重要的作用。同时,从生理生态方面为树鼩的岛屿起源学说提供依据。 |
| 英文摘要: |
| The Tree Shrew(Tupaia belangeri) is a unique species of small mammals in the Oriental realm.In order to study their cold adaptive capacity in cold environment,the Ⅲ state and the Ⅳ state of mitochondrial respiration,the protein content of mitochondria of liver were measured under the condition of being cold exposure(5±1℃,12L:12D) during different times [0 d(control),7 d,14 d,21 d,28 d].Compared with the controls,the total protein,mitochondrial protein,and the Ⅲ state and the Ⅳ state of mitochondrial respiration of liver greatly increased with prolonged cold exposure(increased 39.9%,39.3%,84.9%,181.1%,respectively,after 28 d).The result indicates that the liver plays a key role of the adaptive thermogenesis during cold exposure in the T.belangeri.The physiological ecology evidence is also given to the island origin of T.belangeri. |
