肌肉锻练激发交感肾上腺素能系统是一种重要的生理性应激状态。然而有关肌肉锻练对门静脉血流影响的研究,至今仅有一篇非系统性的报道。为此,本文测定正常人在两种不同类型的踏车锻练前后血浆去甲肾上腺素浓度和门静脉血流,以探讨门静脉血流与锻练后交感肾上腺素能激活的关系。 材料与方法:16例健康志愿者至少住院24小时,清晨空腹,8时始平卧在床进行静脉穿 Muscular exercise to stimulate the sympathetic adrenergic system is an important state of physiological stress. However, there is only one nonsystematic report about the effect of muscle training on the portal vein blood flow. To this end, this paper measured the plasma levels of norepinephrine and portal vein in two different types of treadmill exercise before and after exercise to explore the relationship between portal vein blood flow and post-exercise sympathetic adrenergic activation. Materials and Methods: Sixteen healthy volunteers were admitted to hospital for at least 24 hours, fasting early in the morning,
