我们曾研究了十二种金属离子与电针镇痛的关系,发现脑钙离子(Ca~(2+))水平降低能提高电针镇痛效果,反之则对抗电针镇痛。其它阳离子如K~+、Na~+、Li~+、Cu~(2+)、Sr~(2+)、Ba~(2+)、Zn~(2+)、Co~(2+)、Fe~(2+)、Mg~(2+)和Al~(3+)本身都无镇痛作用。后来观察到,当电针镇痛时,在脑Ca~(2+)量下降的同时伴有脑镁离子(Mg~(2+))量升高,电针镇痛效果与脑Mg~(2+)/Ca~(2+)比值变化有关。适当 We have studied the relationship between twelve kinds of metal ions and electroacupuncture analgesia. We found that the decrease of brain calcium ion (Ca 2+) can improve the analgesic effect of electroacupuncture and vice versa. Other cations such as K +, Na +, Li +, Cu 2+, Sr 2+, Ba 2+, Zn 2+, Co 2+, Fe ~ (2 +), Mg ~ (2+) and Al ~ (3 +) have no analgesic effect. Later observed that when electroacupuncture analgesia, in the brain Ca2 + decreased accompanied by increased levels of magnesium (Mg2 +), electroacupuncture analgesic effect and brain Mg ~ ( 2 +) / Ca ~ (2 +) ratio changes. appropriate
