PurposeWe调查是否组成性内皮细胞一氧化氮合酶(cNOS)和一氧化氮(NO)的控制,通过改变剪切应力可能是重要的调节平滑肌细胞(SMC)的生长和血管diameter.MethodsBilateral股动静脉瘘被放置在狒狒,以增加髂外动脉的血流量。在2个月时,瘘被结扎的一侧恢复正常流量(流量开关)。结果在响应流量开关和剪切应力的减少,髂动脉管腔面积减少,平滑肌细胞增殖诱导。NO产生、cNOS信使RNA(mRNA)和蛋白质的下降与这些生物学效应相关。在一组动物的髂动脉在高流量下,灌注Nω-硝基-L-精氨酸,cNOS的抑制剂,并没有诱导proliferation.Conclusionshear应力可以调节cNOS,血管收缩,SMC增殖。一氧化氮的减少可能是必要的,但不足以诱导SMC因血流量减少而增殖。(J Vasc Surg 1998:28:514-21.)
PurposeWe investigated whether control of constitutive endothelial cell nitric oxide synthase (cNOS) and nitric oxide (NO) by changes in shear stress might be important for the regulation of smooth muscle cell (SMC) growth and vascular diameter.MethodsBilateral femoral arteriovenous fistulas were placed in baboons to increase the blood flow in the external iliac arteries. At 2 months, the fistula was ligated on one side to restore normal flow (flow switch).ResultsIn response to flow switch and a decrease in shear stress, iliac artery lumenal area decreased and SMC proliferation was induced. A decline in NO production, cNOS messenger RNA (mRNA), and protein were associated with these biological effects. In a subset of animals with iliac arteries under high flow, infusion of Nω-nitro-l-arginine, an inhibitor of cNOS, did not induce proliferation.ConclusionShear stress can regulate cNOS, vasoconstriction, and SMC proliferation. A decrease in nitric oxide may be necessary, but is not sufficient to induce SMC proliferation in response to a decrease in blood flow. (J Vasc Surg 1998:28:514-21.)
