The effects of stimulation of acupuncture loci Nei-Kuan (EH-6), Tsu-San-Li (St-36), San-Yin-Chiao (Sp-6) and Chu-Chih (LI-11) on cutaneous circulation and/or pain threshold were assessed in eight normal adults. Stimulation of acupuncture locus San-Yin-Chiao (located in the right leg) produced vasoconstriction in the right leg skin temperature (Tright leg) and in the left leg skin temperature (Tleft leg). There was no change in either right arm skin temperature (Tright arm), left arm skin temperature (Tleft arm), metabolic rate, or respiratory evaporative heat loss. Stimulation of Nei-Kuan (located in the right arm) produced vasoconstriction only in both Tright arm and Tleft arm without changes in Tright leg or Tleft leg. Stimulation of acupuncture locus Tsu-San-Li (located in the left leg) produced vasoconstriction in both Tleft leg and Tright leg without changes in either Tright arm or Tleft arm. Stimulation of acupuncture locus Chu-Chih (located in the left arm) produced vasodilatation in both Tleft arm and Tright arm without changes in either Tright leg or Tleft leg. On the other hand, stimulation of acupuncture locus San-Yin-Chiao (right side) produced analgesia only in the right foot sole, while stimulation of acupuncture locus Chu-Chih (left side) produced analgesia only in the left hand palm. Thus, the data indicate that each acupuncture locus may have its own topographical representation with special reference to both cutaneous circulation and pain threshold in normal adults.
在8名正常成年人中评估了针刺穴位内关（EH - 6）、足三里（St - 36）、三阴交（Sp - 6）和曲池（LI - 11）对皮肤循环和/或痛阈的影响。针刺三阴交穴位（位于右腿）可使右腿皮肤温度（T右腿）和左腿皮肤温度（T左腿）出现血管收缩。右臂皮肤温度（T右臂）、左臂皮肤温度（T左臂）、代谢率或呼吸蒸发散热均无变化。针刺内关穴位（位于右臂）仅使T右臂和T左臂出现血管收缩，而T右腿和T左腿无变化。针刺足三里穴位（位于左腿）使T左腿和T右腿均出现血管收缩，而T右臂和T左臂无变化。针刺曲池穴位（位于左臂）使T左臂和T右臂均出现血管舒张，而T右腿和T左腿无变化。另一方面，针刺三阴交穴位（右侧）仅使右脚底产生镇痛作用，而针刺曲池穴位（左侧）仅使左手掌产生镇痛作用。因此，数据表明，在正常成年人中，每个针刺穴位可能都有其自身在皮肤循环和痛阈方面的特殊体表定位。
