基于性别与季节差异的赤腹松鼠糖脂代谢指标测定
Characterization of Metabolic Indices of Glucose and Lipid in Callosciurus erythraeus Based on Gender and Season

中文摘要：以2015年1-12月捕自四川省荥经县的171只成体赤腹松鼠 Callosciurus erythraeus为研究对象，首次测定了其糖脂代谢8项指标值，并分析了性别、季节及妊娠对指标的影响。结果显示：（1）赤腹松鼠糖脂代谢指标的性别差异无统计学意义。（2）高密度脂蛋白、载脂蛋白B浓度的季节差异无统计学意义，总胆固醇、甘油三酯、低密度脂蛋白、极低密度脂蛋白、葡萄糖浓度为夏、秋季高于春、冬季，载脂蛋白AI浓度为夏、秋季低于春、冬季。（3）妊娠鼠甘油三酯、极低密度脂蛋白浓度高于未妊娠鼠。结果表明，雌、雄赤腹松鼠糖脂代谢指标具有同一性，且大多数指标具有季节差异，这可能与雌、雄鼠的繁殖状态及生活环境的多样性变化有关。
英文摘要：To get better insight of the biochemical features of red-bellied squirrel ( Callosciurus erythraeus),81 males and 90 females were captured in January to December 2015 from Yingjing county,Sichuan province. And 8 metabolic indices of glucose and lipid were measured. The differences of these indices were analyzed according to gender and season. Besides,the impacts of pregnancy in those indices were also analyzed. The results were showed as following: (1) No significant differences were found in the metabolic indices of glucose and lipid between the male and female red-bellied squirrel. (2) No significant seasonal variations were found in high-density lipoprotein and apolipoprotein B in red-bellied squirrel. The serum concentrations of total cholesterol,triglyceride,low-density lipoprotein,very low density lipoprotein and glucose were significantly higher in summer and autumn compared to these in spring and winter. However,the level of apolipoprotein AI in summer and autumn was obviously lower than that in spring and winter. (3) The levels of triglyceride and very low density lipoprotein were higher in pregnant squirrels than these in non-pregnant. These results indicated that the metabolic indices of glucose and lipid of male red-bellied squirrels were consistent with that of female. Almost all of the 8 studied parameters were impacted by seasens,and this may be related to the reproductive status of male and female squirrels and the diversities of environments. 2016,35(5): 748-752 收稿日期：2016-06-01 DOI：10.11984/j.issn.1000-7083.20160148 分类号：Q959.837;Q592.1 基金项目：四川省林业科学研究院自列课题项目（ZL2014-22） 作者简介：靳伟(1982-),男,博士,高级工程师,主要研究方向:生物多样性保护及小型兽类研究,E-mail:58683348@qq.com;贾义平,男,硕士研究生,主要研究方向:中西兽医与临床,E-mail:gehuan199203@126.com *通讯作者：左之才,E-mail:ZZCJL@126.com 参考文献： 蔡红霞, 冉江洪, 张家平, 等. 2001. 赤腹松鼠危害季节性变化与食性的初步探讨[J]. 四川林业科技, 22(3): 21-24. 何建平, 李金钢, 王智, 等. 2001. 棕色田鼠血液生理生化指标的测定[J]. 动物学杂志, 36(6): 50-53. 靳伟, 贾义平, 左之才, 等. 2015. 荥经县赤腹松鼠血液生理指标测定与分析[J]. 四川林业科技, 36(4): 37-40. 刘海青, 王宝菊, 张静宵, 等. 2015. 喜马拉雅旱獭血液生化指标测定[J]. 四川动物, 34(5): 764-766. 刘敬盛, 杨玉芝, 王君荣, 等. 2010. 胆汁酸的营养特性及其在家禽生产中应用的研究进展[J]. 中国畜牧兽医, 37(1): 13-16. 孙玉波, 贾岗, 纪岷, 等. 2012. 四川洪雅县赤腹松鼠的食性观察[J]. 四川动物, 31(5): 786-789. 陶元清, 范微, 王忠东, 等. 2010. 喜马拉雅旱獭血液生理指标测定[J]. 四川动物, 29(5): 625-626. 王冬平, 隋丽华, 尚世臣, 等. 2009.
