Total pulmonaryresistance(TPR), pulmonary vascular resistance(PVR)and systemic vascular resistance(SVR) were increased after injected NOS inhibitor(P<0.05).
在注入NOS抑制剂后总肺循环阻力、肺动脉阻力、体循环血管阻力均明显上升（P< 0 .0 5 ）。

Pulmonary vascular is an effector of baroreceptor reflex, which can exert significant control of pulmonaryresistance and capacitance after orthostatic challenge.
肺血管是压力反射效应器的一部分，立位应激时的压力反射很大程度上控制着肺循环的阻力和容量。

Pulmonary artery pressure and pulmonaryresistance increased markedly after pulmonary embolism, which were lowered progressively and significant by thrombolytic therapy in contrary with control dogs.
