Abstract

1 The two peptides calcitonin gene related peptide (CGRP) and vasoactive intestinal peptide (VIP) produced marked dilatation of the forearm vascular bed when infused via the brachial artery. 2 CGRP relaxed preconstricted segments of human radial, coronary, gastric and cerebral arteries in an endothelium dependent manner. 3 VIP relaxed human gastric and transverse cervical arteries in an endothelium dependent manner, but relaxation of the human pulmonary artery was not dependent on endothelium. 4 The characteristics of the endothelium dependent relaxation of these medium-sized muscular arteries indicated involvement of the endothelium derived relaxing factor in vitro. 5 Caution is expressed in drawing comparisons between the mechanisms involved in the in vivo and in vitro vascular responses.

摘要
  1. 降钙素基因相关肽(CGRP)和血管活性肠肽(VIP)这两种肽经肱动脉注入时,可使前臂血管床显著扩张。2. CGRP以依赖内皮的方式舒张人桡动脉、冠状动脉、胃动脉和脑动脉的预收缩节段。3. VIP以依赖内皮的方式舒张人胃动脉和颈横动脉,但人肺动脉的舒张不依赖内皮。4. 这些中膜肌性动脉的内皮依赖性舒张特征表明,体外存在内皮源性舒张因子的参与。5. 在对体内和体外血管反应所涉及的机制进行比较时需谨慎。
