| 中文摘要: |
| 以捕自四川荥经县的161只成体赤腹松鼠（Callosciurus erythraeus，雄鼠76只，雌鼠85只）为研究对象，从2015年2月至12月分四个季节测定了雌、雄鼠血清中反映肝肾功能的14项指标，并分析了妊娠对各项指标的影响。结果显示：（1）肝肾功能指标均无显著的性别差异。（2）白蛋白、胆碱酯酶和肌酐在春季有升高的趋势，但无明显的季节差异。（3）总蛋白、球蛋白及尿酸含量春季低于其他季节，总胆红素、直接胆红素、间接胆红素和尿素氮含量春季高于其他季节，前白蛋白、丙氨酸氨基转移酶、天冬氨酸氨基转移酶和γ-谷氨酰转移酶春季高于其他季节，夏季显著下降，冬季最低。（4）妊娠鼠血清胆碱酯酶含量高于未妊娠鼠，尿素氮、肌酐和尿酸含量低于未妊娠鼠。结果表明，雌、雄赤腹松鼠肝肾功能指标无性别差异且季节变化趋势相同，大多数在春季变化显著且妊娠影响较小，这可能与雌、雄的繁殖状态及在多变性环境条件下的生理适应能力有关。 |

| The aim of the study was to get better insight of some biochemical parameters reflecting hepatic and renal functions in the blood plasma of Red-bellied Squirrel (Callosciurus erythraeus). During the course of a one-year period 76 male and 85 female adult squirrels were captured from February to December 2015, respectively from Yingjing County, Sichuan Province. These indices were statistically analyzed for differences between gender, season and pregnancy by two-way ANCOVA or one-way ANCOVA. No significant sex difference was found for serum hepatic and renal function markers in red-bellied squirrel (Fig. 1﹣3). No significant difference but higher serum concentrations of albumin (Fig. 1b), cholinesterase (Fig. 1c) and creatinine (Fig. 3a) were found in the spring compared to the other seasons. The serum concentrations of total protein (Fig. 1d), globulin (Fig. 1e) and uric acid (Fig. 3c) were significantly higher in the spring, while total bilirubin (Fig. 2a), direct bilirubin (Fig. 2b), indirect bilirubin (Fig. 2c) and blood urea nitrogen (Fig. 3b) were obviously lower. Alanine aminotransferase (Fig. 2d), pre-albumin (Fig. 1f), aspartic transaminase (Fig. 2d) and γ-glutamine transferase (Fig. 2f) concentrations were significantly higher in the spring compared to other seasons and markedly decreased in the summer, then reached nadir in the winter. Serum concentrations of blood urea nitrogen (Fig. 4a), creatinine (Fig. 4b) and uric acid (Fig. 4d) were significantly lower in pregnant squirrels compared to non-pregnant individuals, while the concentration of cholinesterase (Fig. 4a) was significantly higher in pregnant squirrels. These results indicated seasonal differences in blood biochemical parameters in red-bellied squirrels. Most of the studied parameters were the lowest or highest in the spring, but less impacted by pregnancy. This might be related to reproductive status of male and female squirrels and the ability of physiological adaptation to the diversities of environments. |
