To evaluate the contribution of vagal and sinoaortic baroreflexes in circulatory adjustments anaesthetized rabbits were subjected to 70 degree head up tilt with (i) both reflexes intact; (ii) after elimination of sinoaortic reflexes; (iii) after elimination of vagal reflexes; and (iv) after elimination of both categories of reflexes. The results suggest that vagal mediated baroreflexes from cardiopulmonary baroreceptors contribute significantly in circulatory adjustments to passive head up tilt while sinoaortic baroreflexes play the major role.
为评估迷走神经和窦弓压力反射在循环调节中的作用,对麻醉兔进行70度头高位倾斜试验,试验条件如下:(i)两种反射均完整;(ii)消除窦弓反射后;(iii)消除迷走神经反射后;(iv)消除两类反射后。结果表明,来自心肺压力感受器的迷走神经介导的压力反射在被动头高位倾斜的循环调节中起重要作用,而窦弓压力反射起主要作用。
