1·The results show; (1) The increased hepatic vasoconstrictor reactivity and the adhesive function of platelets in viral infection are the basic mechanism of the hepatic microcirculatory disturbance.
结果提示：（1）在病毒感染中肝血管收缩反应性上升及血小板粘附功能增强是肝微循环障碍发生的基础。
2·Conclusion CRA seems to be relate to the renal and splenic hemodynamics, also relate to the histology, the Doppler parameters of portal hypertension and the activity of vasoconstrictor systems.
结论视网膜中动脉可能与肾脏、脾脏的血流动力学变化有关，同样与组织学、门脉高压多普勒参数和血管收缩系统的活性有关。
3·Endothelin (ET) is a recently discovered potent vasoconstrictor peptide exerting effects through combination with its receptor.
内皮素(et)是一种血管收缩肽，与et受体结合而发挥作用。
