Abstract
Reflex responses of adrenal sympathetic nerve activity to stimulation of baroreceptor and cutaneous mechanoreceptors were compared in young adult (4 months old) and aged (26 months old) rats, under strictly controlled conditions for anesthesia, respiration and body temperature. Under these conditions the reflex depression to baroreceptor stimulation and cutaneous brushing and reflex excitation to cutaneous pinching were quite well maintained during aging.
摘要
在严格控制麻醉、呼吸和体温的条件下，比较了年轻成年（4个月大）和老年（26个月大）大鼠肾上腺交感神经活动对压力感受器和皮肤机械感受器刺激的反射反应。在这些条件下，衰老过程中对压力感受器刺激和皮肤轻刷的反射性抑制以及对皮肤捏压的反射性兴奋都得到了很好的维持。
