The authors have studied the vasomotor status and digital vascular reactivity to cold in a series of 37 healthy volunteers (18 women and 19 men; mean age 30.6 years, range: 24-34) using digital mercury strain-gauge plethysmography. Correlations between digital blood flow and sex or other individual parameters (height, weight, smoking habits ...) were particularly looked for. Women's digital vascular tone evaluated under standardized conditions was found superior to men's, thus corroborating clinical and experimental data reported in literature. On the other hand, vasculotropic digital reactivity to local cooling was found similar in women and men. Moreover, no visible effect of local cooling was evidenced on the non-tested contralateral hand, suggesting the absence of significant general sympathetic influence during local cooling test.
作者使用数字汞应变计体积描记法，对37名健康志愿者（18名女性和19名男性；平均年龄30.6岁，范围：24 - 34岁）的血管舒缩状态和手指血管对寒冷的反应性进行了研究。特别研究了手指血流量与性别或其他个体参数（身高、体重、吸烟习惯等）之间的相关性。在标准化条件下评估的女性手指血管张力优于男性，从而证实了文献中报道的临床和实验数据。另一方面，发现女性和男性对手部局部冷却的血管性反应相似。此外，未测试的对侧手未显示局部冷却的明显影响，这表明在局部冷却测试期间不存在明显的全身性交感神经影响。
