摘      要：正 Experiments were performed on stress-induced hypertensive rats anesthetized with urethane andchloralose. The ECG, blood pressure （BP）, cardiac functions: PEAK, end diastolic pressure（EDP）, ±dp/dt were recorded synchronously. Microinjection of saline into the ventral periaqueductal gray matter （vPAG） caused no signifi-cant change of the above parameters. While microinjection of L-Arginine resulted in a decrease in
