MAP was monitored,24 hour survival rate and the level of plasma NO - 2/NO - 3,the stable metabolic end products of NO,were determined. Results Plasma NO - 2/NO - 3significantly increased and MAP gradually decreased after ETX administration.

• 上述处理后 ,测定大鼠不同时间的平均动脉压 (meanarterialpressure ,MAP)、血浆NO水平 (NO-2 /NO-3 )以及 2 4小时存活率。
