摘要： 为了阐明内分泌激素在中缅树鼩体重调节中的作用，模拟夏季和冬季环境，测定了其血清瘦素含量、胰岛素含量和甲状腺素含量。结果表明：中缅树鼩的血清瘦素水平在模拟冬季环境中显著降低；胰岛素水平与瘦素水平呈显著的正相关，说明中缅树鼩胰岛素能够正向调节和刺激瘦素的分泌；模拟冬季环境显著增加甲状腺素T3含量，从而增强其产热能力，而模拟夏季环境对其影响不大，呈现出降低的趋势，在一定程度上减弱了产热。以上结果说明中缅树鼩在季节性变化过程中会通过调整内分泌激素的含量来调节其能量代谢。

Abstract: In order to investigate the roles of endocrine hormone in the regulation of body mass of Tupaia belangeri, serum leptin levels, insulin levels, and the levels of thyroid hormone under simulating winter and summer environments were measured. The results showed that serum leptin levels in T. belangeri in simulating winter environment reduced significantly with the acclamation time; insulin levels were significantly correlated to leptin levels, indicating that insulin could positively modulaten and stimulate leptin secretion in T. belangeri; simulating winter environment increased thyroid hormone T3 levels significantly, thereby enhancing the heat production capacity, and simulated summer environment had no obvious influence on the thyroid hormone T3 levels, but showed a decreasing trend in a certain extent, weakened the heat production. All of these results suggested that T. belangeri in seasonal change process will be through the adjustment of endocrine hormone levels to regulate the energy metabolism.
