A vivid tissue responds various mechanisms when
stimulated by any kind of stimulator (i.e.
mechanical, thermal or electrical).
When the acupuncture needle is pierced, series
of reactions (according to type of the metal)
are observed in the tissue, in the cell
mitochondrial region where the needle is pierced
produces glycols and relating to this, lactate
and pruvat that are produced inside the cell
burn under aerobic conditions and produces ATP.
In this ATP, where the needle is pierced, energy
and electrical changes occur.
With the piercing of the needle, a direct
relation with the interstitial liquid and the
needle starts. According to the type of the
metal, ions may transmit to liquid and outside
the needle (-), becomes in other words, Cathode.
This reaction occurs with the silver needle and
has inhibitor affect.
When gold needle is pierced, however, ion
transmission from interstitial liquid to the
needle starts and the outer side of the metal
becomes a (+) pole, Anode. As a result of this
reaction, K(-) accumulates in the nerve
terminals and excitatory stimulation starts. On
the other hand, in the silver needle, Ca+
accumulates in the nerve terminals and this acts
like an inhibitor.
A Galvanic current forms between the
interstitial liquid and the needle because of
the different ion concentration and this causes
the stimulation in the nociceptors. When the
needle was inside the tissue a galvanic current
and as a result of this, Cl and H2 gases gather
around the needle. According to that, the
electrical potential difference between the
metal and the tissue decreases gradually. In
order to prevent this, the needle has to be
rotated every 3-4 minutes or has to be pierced
and pulled off slightly. And if we want to
create an inhibitor effect, there is no need to
take this action.
