THERMOLYTIC EFFECT OF MOXIBUSTION AND ITS RELATION TO ACUPOINT RECEPTORS

In the present paper, the effect of moxibustion stimulation (by using a computer automaticallycontrolled condensed light) of Dazhui (GV 14) etc. on auricular temperature changes was observed in the rabbit after intravenous injection of endotoxin. Changes of rabbit’s auricular temperature were sampled and recorded by using a thermistorthermometer (connected with a computer) before and after moxibustion stimulation. Results indicated that moxibustion making the skin temperature reach to 48℃ could inhibit the endotoxininduced lowering reaction of auricular temperature, while moxibustion making the skin temperature of 40℃ had no this effect. It revealed that higherskintemperature moxibustion had a thermolytic effect on bodyfever, which had a close relation mainly with polymodal receptors rather than with temperature receptor. It also demonstrated that endotoxininduced changes of auricular temperature could be used as an index for evaluating the thermolytic effect of moxibustion.

目的 :研究外侧隔核是否是蝎毒产生中枢镇痛作用的重要部分之一。方法 :用玻璃微电极记录束旁核的单位放电 ;通过不锈钢套管向外侧隔核内微量注射 0 .0 3%蝎毒。结果 :外侧隔核内微量注射0 .0 3%蝎毒可以明显地减弱束旁核内的痛兴奋神经元和痛抑制神经元对伤害性刺激的反应。结论 :外侧隔核是蝎毒产生中枢镇痛作用的重要部位之一。
