急性肺栓塞使肺动脉压力及肺血管阻力明显升高，溶栓疗法使肺动脉压力及肺血管阻力明显降低，对照组两参数在栓塞后随时间无明显变化。
Pulmonary artery pressure and pulmonary resistance increased markedly after pulmonary embolism, which were lowered progressively and significant by thrombolytic therapy in contrary with control dogs.
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 vascular is an effector of baroreceptor reflex, which can exert significant control of pulmonary resistance and capacitance after orthostatic challenge.
急性或慢性的低氧都能使肺血管收缩，血流阻力增大。
Both acute or chronic hypoxia can cause vasoconstriction and vasoconstriction increase.
PAF增高肺血管压力和阻力的机制不是通过抑制EDRF合成的途径，EDRF不能阻断PAF引起的肺血管张力升高。
The mechanism by which PAF increased pulmonary vascular pressure and resistance was not through inhibition of EDRF synthesis. EDRF did not block PAF-induced changes in pulmonary vascular tone.
