用全细胞(whol-cell)膜片箝记录技术研究失血性休克阻力血管对儿茶酚胺类血管活性药物的反应性降低时期,肠系膜动脉平滑肌细胞(VSMCs)Ca2+通道的变化,以及阻断阿片受体对它们的调控作用。结果发现:失血性休克阻力血管对NE的低反应期。血管平
To investigate the changes of Ca2 + channels in mesenteric artery smooth muscle cells (VSMCs) during the period of reduced reactivity of hemorrhagic shock resistance vascular to catecholamine vasoactive drugs by whole cell (whol-cell) patch-clamp recording technique and to investigate the effects of blocking opioid receptor Their regulatory role. The results showed that: hemorrhagic shock resistance blood vessels to the NE low response period. Blood vessel level
