| 摘 要： | 为探讨大绒鼠妊娠期是否出现瘦素抵抗(Leptin resistance)。测量了野外捕捉的42只成年雌性大绒鼠的体重、脂肪重量和血清瘦素浓度。结果发现,有怀孕鼠8只,体重和血清瘦素浓度显著高于非怀孕鼠34只。血清瘦素浓度与体重和脂肪含量显著正相关。结果表明,妊娠期大绒鼠可能存在瘦素抵抗,允许其体重调节点升高,适应妊娠期能量需求的增加。

| Abstract: | In order to investigate whether to exist leptin resistance in pregnant Eothenomys miletus,body mass,body fat content and serum leptin levels in the field of female E.miletus （42）were measured in this study.It shown that body mass and serum leptin levels in pregnant voles（8）were higher than that in non-reproductive voles（34）.In addition,serum leptin levels were positively correlated with body mass and body fat content.These results suggested that pregnant voles may exist the phenomenon of leptin resistance which increased body mass set-point to adapt the high energy demands for pregnancy. |
