在复习婴儿突然死亡综合征时．发现肺小动脉壁的肌增加和右心室重量增加。这就说明生长在高原的小孩存在心肺功能不良．血管内皮合成一氧化氛．从而使血管平滑肌得以松弛，它也可能是一种重要的神经传导物质．有人证明，一氧化氛在调节血管张力。血压，血流以及降低心室输出方?
When reviewing sudden infant death syndrome. Muscle wall was found to increase muscle and right ventricular weight gain. This shows that children growing in the plateau have cardiopulmonary dysfunction. Endothelial synthesis of an oxidant. As a result, vascular smooth muscle can be relaxed, it may also be an important neurotransmitter. It has been shown that an oxidant regulates vascular tone. Blood pressure, blood flow and reduce ventricular output side?
