When a living tissue is stimulated by any mechanical, thermal or electrical stimulus, it responds to various mechanisms.
When you insert the acupuncture needle, a series of reactions occur in the tissue depending on the type of metal, glycolysis in the cell mitochondrion in the area where the needle is inserted, and lactate and pyruvate produced in the cell due to this are burned under aerobic conditions and ATP is produced. This leads to an energy and electrical change at the immersed point in the ATP produced.
With the insertion of the needle, a direct relationship between the interstitial fluid and the needle begins. Depending on the type of metal, ions can pass into the liquid and the outside of the needle ( – ), in other words, becomes the cathode. This reaction happens with a silver needle and has an inhibitory effect.
When the gold needle is inserted, ion transfer starts from the interstitial fluid to the needle and the outer surface of the metal becomes (+) pole anode. As a result of this reaction, K+ accumulates in the nerve terminals and exitator stimulation begins. In the silver needle, however, Ca (+) accumulates at the nerve terminals, which has an inhibitory effect.
Due to the different ion concentration between the needle and the interstitial fluid, a Galvanic current is formed and this causes excitation in the nociceptors. As a result of the galvanic current that occurs while the needle is in the tissue, Cl and H 2 gases are collected around the needle. As a result, the electric potential difference between the metal and the tissue gradually decreases. In order to prevent this, the needle should be turned every 3-4 minutes or slightly pricked and withdrawn (ie stimulation = warning must be made). If we want to create an inhibitory effect, there is no need to do this work. Gold needles are (+) loaded, silver needles are (-) loaded, and steel needles are neutral.
Needles create a reaction in the area where they are inserted, Seratonin and so on. releases minerals. It allows the body’s defense mechanisms (eg: leukocytes, platelets, IL-3, T. Lymphocytes, etc.) to rush to the region, and also adrenaline, nor-adrenaline, dopamine, serotonin, beta-endorphin, ACTH, etc. from the central nervous system. secretes substances such as Thus, it provides treatment for the target organ and pathology.
