After treatment with the above hormones, the rats were established anesthesia with urethan (1g/kg, i. p.); polyethylene catheters were inserted into the external jugular vein and the common carotid artery for drug administration, and then blood pressure was recorded. The arterial catheter was connected to a pressure transducer, and the blood pressure was displayed on the channel of BL-310 Experimental System of Biological Function through IBM computer. We assessed the changes of resting arterial blood pressure, the pressor responses of angiotensin Ⅱ(Ang Ⅱ, 0.01mg/kg), noradrenaline (NA, 0.01mg/kg) and adrenaline (Adr, 0.016mg/kg).
