Comparison of Oxygen Consumption between Clethrionomys rufocanus and Apodemus agrarius

[ Objective] The paper was to find out the difference in oxygen consumption between Clethrionomys rufocanus and Apodemus agrarius. [ Method] The oxygen consumption value of C. rufocanus and A. agrarius was measured using improved closed pressure breathing apparatus, and the oxygen consumption rate was calculated. [ Result] The oxygen consumption of C. rufocanus and A. agrarius increased with the increasing body weight, while the increase amplitude ofA. agrarius was relatively smaller. The oxygen consumption rate decreased with the increasing body weight. [ Conclusion] The result provides a biological basis for breeding and research of experimental rats.

大林姬鼠和棕背䶄生物学指标对比分析

为了解大林姬鼠(Apodemus peninsulae)和棕背䶄(Clethrionomys rufocanus)生物学指标上的差异,对两种鼠进行解剖,并对相关指标进行测量和比较分析。结果表明,雄性大林姬鼠和雄性棕背䶄在体长、前足长、尾长上均差异极显著(P<0.01),耳长差异显著(P<0.05),后足长差异不显著;雌性大林姬鼠和雌性棕背䶄在体长、耳长、足长、尾长上均差异极显著(P<0.01);大林姬鼠和棕背䶄的体重、胴体重、心脏重、肺脏重、胃重均差异极显著(P<0.01),脾脏重、肾脏重差异不显著。雄性大林姬鼠和雄性棕背䶄的肝脏重差异显著(P<0.05)。雌性大林姬鼠和雌性棕背䶄的肝脏重差异不显著。
