The action of acupuncture stimulation on analgesia has been investigated. The brain and serum extracts of acupunctured rabbits injected into rabbits produced a marked analgesic effect on the recipient, as shown by a great increase of their pain threshold. This effect is counteracted by a specific opiate anatagonist, naloxone. The data suggest that the release of the endogenous substances with morphine-like biological properties, endorphins, is increased by acupuncture stimulation, thus inhibiting pain perception.
针刺刺激对镇痛作用的研究已经展开。将针刺家兔的脑及血清提取物注射到家兔体内，可使受体产生显著的镇痛效果，表现为其痛阈大幅提高。这种效应可被一种特异性阿片拮抗剂纳洛酮所抵消。这些数据表明，针刺刺激可增加具有吗啡样生物学特性的内源性物质——内啡肽的释放，从而抑制痛觉。
