钾、钙离子是神经、肌肉兴奋的关键离子

也是经络传导、针灸得气中必然参与的物质

但其在整体活动过程中变化的规律

尚缺乏直观的功能研究方法。我研究室最近首创试制成功了一种对[K

]、[Ca+]

、[Ca

(++)

]敏感的“针灸电极”

可以对活体进行快速、特异、K(++)]

are important ions in the nerve or muscle excitation

and itsmay be important too in the channel conduction and needling reaction.In this paper

a K(++) are important ions in the nerve or muscle excitation

a K

ion sensitive and selective acupuncture electrode is prepared in our laboratory. By this means

the dynamic observation of K(++) ion sensitive and selective acupuncture electrode is prepared in our laboratory. By this means

the dynamic observation of K

in the acupu- ncture point during acupuncture is realized.In these results:(1)The changes of extracellular K(+2) in the acupu- ncture point during acupuncture is realized.In these results:(1)The changes of extracellular K

ion in“Znsanli”acupoint was increased during needling stage and after acupuncture the K+ ion in“Znsanli”acupoint was increased during needling stage and after acupuncture the K

ion was significant decreased

(p

0.01). It showed the delayed effect of acupuncture and the mechanism may be to stimulate the sodiumpotasium pump in the acu(?)oint

which caused the extra- cellular K+ ion was significant decreased

ion (see above) during acupuncture the same channel but in different aeupoint (Tiao kou)

and no simillar effect showed on K+ ion (see above) during acupuncture the same channel but in different aeupoint (Tiao kou)

the correlation between acupoint and viscera were showed in all of these experiments.(3) The obvious change of Ca+ ion during acupuncture the pericardium channel.However

the correlation between acupoint and viscera were showed in all of these experiments.(3) The obvious change of Ca

ion in different acupoints were showed but not significant and the change is not same as the K(+2) ion in different acupoints were showed but not significant and the change is not same as the K

ion and the mechanism was further discussed.
