众所周知,针刺或通过皮肤电流刺激对腰背酸痛和牙痛等均能起到一定缓解作用,而吗啡拮抗药—naloxone则能减弱或抵销这些作用,因此上述刺激方法被认为是通过同样的神经机制调节的。最合理的假说则认为:不论皮肤表面受到电的刺激或深层组织受到针刺之后,这些强的感觉输入将冲动送入脑干,然后通过传出系统并“关闭”从其它部位来的痛觉。naloxone能逆转电刺激人和动物中央灰白质所产生的止痛作用而针刺止痛效果要求完好之脑干功能。由此引申,其它类型之强烈刺激如冷,热,压迫等亦应能
It is well-known that acupuncture or skin current stimulation can relieve back pain and toothache, while morphine antagonist-naloxone can weaken or counteract these effects. Therefore, the above stimulation method is considered to be through the same nerve Mechanically adjusted. The most plausible hypothesis is that these strong sensory inputs impulse into the brainstem regardless of the electrical stimulation of the skin surface or acupuncture of deep tissues, and then pass the sensation of the system and “turn off” the rest of the body. naloxone reverses the analgesic effect of electrical stimulation of central and white matter in humans and animals while acupuncture has the best brain stem function required for pain relief. From this extension, other types of strong stimuli such as cold, heat, oppression, etc. should also be able to
