１４６只雄性Ｗｉｓｔａｒ大鼠，慢性应激２０天，诱发早期可逆性应激性高血压，在应激４～１６天血压逐渐增高的高血压发生期，同时观察交感紧张性和动脉压力感受反射敏感性的变化。结果发现，交感紧张性升高超前于血压的变化，随后在血压继续升高过程中趋于回降，动脉压力感受反射则伴随血压升高而逐渐衰减。这提示，交感紧张性升高主要在高血压发生中起重要作用，动脉压力感受反射的衰减，可能参与高血压的发展和维持，两者的产生可能来源于不同的中枢机制。
146 male Wistar rats, chronic stress for 20 days, induced early reversible stress-induced hypertension in the stress 4 to 16 days of increasing blood pressure during the onset of hypertension, while observing the sympathetic tone and arterial baroreflex sensitivity Sexual changes. The results showed that sympathetic tone increased in advance of changes in blood pressure, and then tend to fall back in the process of rising blood pressure, arterial pressure-sensitive reflex with the blood pressure and gradually decay. This suggests that sympathetic tone rise mainly plays an important role in the occurrence of hypertension, attenuation of arterial pressure-sensing reflex may be involved in the development and maintenance of hypertension, both of which may originate from different central mechanisms.
