目的:对比格犬发情期与间情期ERβ基因在性腺组织器官的变化状况进行荧光定量,明确ERβ基因在发情期与间情期下丘脑-垂体-性腺轴上的表达量差异情况,为深入研究比格犬发情机制提供基础. 方法:作为调控生殖的关键基因,ERβ基因位于比格犬下丘脑-垂体-性腺轴上,因此分别取处于发情期和间情期的比格犬,提取下丘脑、垂体、卵巢和子宫的RNA,反转录后对ERβ基因mRNA 的表达量进行荧光定量PCR 检测. 结果:间情期比格犬卵巢、子宫、垂体、下丘脑内ERβ基因mRNA 的表达量分别是发情期比格犬卵巢、子宫、垂体、下丘脑内ERβ基因mRNA 表达量的0.35倍、0.17倍、0.44倍、0.43倍. 结论:ERβ基因在处于发情期的比格犬下丘脑-垂体-性腺轴内表达量均上调.

目的:验证低强度颈迷走神经干刺激是否能够预防和逆转心房颤动以及房颤诱导的心房重构。方法:33条雄性犬分为5组,每条犬均接受刺激仪同时对双侧迷走神经进行连续的高频率刺激,频率为20HZ,脉宽为0.1 ms。刺激时能引起窦性心率下降或房室传导阻滞的最低电压定义为闺值电压。低强度刺激则定义为闭值强度的50%或90%。实验组1(n=7):实验犬接受6个小时的心房快速起搏,从第4个小时起同时进行低强度颈迷走
