已有许多研究表明,内皮源性一氧化氮(NO)能调节动脉血管的张力,这种基础NO活性可通过选择性NO合酶抑制剂(L-NMMA)拮抗作用而显示。关于NO能否调节静脉血管张力的研究报道很少,本研究旨在探讨基础NO活性和刺激后NO活性在调节人静脉容量血管床张力中的作用。选择24例无心血管病危
Numerous studies have shown that endothelium-derived nitric oxide (NO) modulates arterial vascular tone and this basal NO activity is shown by antagonism of selective NO synthase (L-NMMA) antagonism. There are few reports on whether NO regulates venous vascular tone. This study aimed to explore the role of basal NO activity and post-stimulation NO activity in regulating venous pressure in human venous. Choose 24 cases of cardiovascular disease risk
