方法受试者为19-35岁的健康男女，在整个实验过程中穿着正常的室内服装，舒适保暖。用量热法跟踪手指的血流情况（Greenfield & Shepherd, 1950）。在29-30℃或0-2℃下测量指尖远端2-8 cm到水的热损失。在所有实验中，手指首先在29℃的水中浸泡10分钟。在那些在动脉内注射组胺和乙酰胆碱的实验中，在观察开始之前，将一根针插入肘部的肱动脉。
METHODS The subjects were healthy men and women aged 19-35 yr. They wore normal indoor clothing and were comfortably warm throughout the experiments. The blood flow through the finger was followed by the calorimetric method (Greenfield & Shepherd, 1950). The heat loss was measured from the distal 2-8 cm of finger tip to water either at 29-30G C or 0-2'C. In all experiments the fingers were first immersed for 10 min in water at 29'C. In those experiments in which histamine and acetylcholine were administered intra-arterially a needle was inserted into the brachial artery at the elbow before the observations were started.
