Intrasi- nusal pressure -mean arterial pressure res- ponse curves were constructed.

在自然状态下，各种传入冲动汇集中枢，很多传入冲动都可影响压力感受性反射，使压力感受性反射受到调制而发生重新调定·本实验旨在观察刺激躯体神经对压力感受性反射的重调定并分析其机制·实验在α-氯醛糖和氨基甲酸乙酯混合麻醉的家兔上进行，利用颈动脉窦灌流技术测量不同窦内压时体循环平均动脉压的水平，并画出窦内压-体循环平均动脉压反应曲线。

Both ACEI with or without sulfhydryl groups could prevent the H2O2 induced decrease in contraction responses to PE in intact aortic rings. The increase of NO and activation of HO-1 might be involved in the mechanism.

含有和不含筑基的ACEI均具有对抗H2O2引起的血管收缩功能下降的作用，其主要机制可能是通过引起NO产生增加和诱导HO-1而实现的。
