[Neuropharmacological analysis of electroacupuncture analgesia]

Iasnetsov VV.

It was established in experiments on conscious rats using concurrent recording of pain sensitivity and evoked potentials that the leading part in electroacupuncture analgesia is played by endogenous opioid peptides. However, numerous pharmacological substances can alter the level of electroacupuncture analgesis suggesting the participation in its genesis of different mediator cerebral systems. In the animals resistant to acupuncture, administration of morphine did not produce marked analgetic effect.
