To determine whether vascular reactivity in the young animal is significantly different from that of the mature animal, helical strips of thoracic aorta were suspended in an organ bath of Krebs bicarbonate solution, and isometric tension was measured. The effects of norepinephrine, phenylphrine, tyramine, and KCl were studied. The neonatal vascular strips were less sensitive than adult strips to the adrenergic agents, but responsiveness to KCl was comparable in both groups.
为了确定幼龄动物的血管反应性是否与成年动物有显著差异，将胸主动脉螺旋条悬于 Krebs 碳酸氢盐溶液的器官浴槽中，测量等长张力。研究了去甲肾上腺素、去氧肾上腺素、酪胺和氯化钾的作用。新生动物的血管条对肾上腺素能药物的敏感性低于成年动物的血管条，但两组对氯化钾的反应性相当。
