First toe systolic blood pressures (FTSBP) before and after first toe cooling were measured with the laser Doppler method in 17 normal women and 10 female patients with primary Raynaud's phenomenon (PRP). The room temperature was maintained at 26 degrees C. There was no significant difference in toe-arm systolic blood pressure ratio between the two groups. After toe cooling at 10 degrees C, the PRP group had a significantly greater reduction in FTSBP than the normal group. Measurement of FTSBP before and after toe cooling is a useful method for assessing Raynaud's phenomenon in the toes of patients with PRP.
采用激光多普勒法测量了17名正常女性和10名原发性雷诺现象（PRP）女性患者在第一趾冷却前后的第一趾收缩压（FTSBP）。室温保持在26摄氏度。两组之间的趾臂收缩压比值无显著差异。在10摄氏度的趾冷却后，PRP组的FTSBP下降幅度明显大于正常组。测量趾冷却前后的FTSBP是评估PRP患者脚趾雷诺现象的一种有用方法。
