在身体加热期间，由于交感神经介导的血管舒张，手和前臂的血流量大幅增加。在前臂，血管扩张仅限于皮肤血管（Barcroft，Bock，Hensel & Kitchin，1955; Edholm，Fox & Macpherson，1956; Roddie，Shepherd & Whelan，1956），有证据表明手部也是如此（Harris，Martin &威廉姆斯，1952）。前臂皮肤的血管供应有血管扩张纤维（Grant & Holling，1938; Edholm等人，1956; Roddie，Shepherd & Whelan，1957）和血管收缩纤维（Roddie等人，1957年）。目前的证据表明，正常受试者的手的血管仅供应有血管收缩纤维（Arnott & Macfie，1948; Gaskell，1956），尽管刘易斯& Pickering（1931）的实验表明雷诺氏病患者的手存在血管扩张纤维。本实验的目的是确定血管扩张和血管收缩纤维的贡献，在上肢皮肤扩张，在身体加热。
During body heating there is a large increase in hand and forearm blood flow owing to vasodilatation mediated by sympathetic nerves. In the forearm the vasodilatation is confined to the vessels of the skin (Barcroft, Bock, Hensel & Kitchin, 1955; Edholm, Fox & Macpherson, 1956; Roddie, Shepherd & Whelan, 1956), and there is some evidence that this is also the case in the hand (Harris, Martin & Williams, 1952). The vessels of the forearm skin are supplied with both vasodilator fibres (Grant & Holling, 1938; Edholm et al. 1956; Roddie, Shepherd & Whelan, 1957) and vasoconstrictor fibres (Roddie et al., 1957). Present evidence indicates that the blood vessels of the hands of normal subjects are supplied only with vasoconstrictor fibres (Arnott & Macfie, 1948; Gaskell, 1956), although the experiments of Lewis & Pickering (1931) suggest that there are vasodilator fibres to the hands of patients with Raynaud's disease. The object of the present experiments was to determine the contribution of vasodilator and vasoconstrictor fibres to the skin dilatation in the upper limb during body heating.
