下丘脑室旁核NOS/NO系统对心血管活动的调节(综述)

Effect of NOS/NO system in paraventricular hypothalamic nucleus on the regulation of cardiovascular activity(A review)

下丘脑室旁核 (PVN)是重要的心血管活动调节中枢。PVN分布有一氧化氮(NOS)神经元 ,合成并释放一氧化氮 (NO)。NO通过抑制各级交感神经中枢 ,以及影响神经内分泌活动 ,对心血管活动进行调节。

Paraventricular hypothalamic nucleus (PVN) is an important center in the regulation of the cardiovascular activity . Nitric oxide synthase (NOS) positive neurons, which are located in PVN , produce and release the gas, nitric oxide (NO). NO play a role in the regulation of the cardiovascular activity through the inhibition of several level autonomic nervous centers , or through the effect of neuroendocrine functions.
