中文摘要：

中缅树鼠句（Tupaia befangeri）为东洋界特有小型哺乳动物。本研究测定了中缅树鼠句冷驯化实验组（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，探讨中缅树晌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，中缅树晌产热显著增加，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，肝在中缅树嗣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鼠句的岛屿起源学说提供依据。

英文摘要：

The Tree Shrew （ Tupaia belangeri ） is a unique study their cold adaptive capacity in cold environment, the species of small mammals in the Oriental realm. In order to 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.
