Abstract:
Acupuncture effects are frequently modified by additional acupuncture stimulations. In this study we tried to clarify the mechanisms of such phenomena using the rat jaw opening reflex. The reflex response was elicited by an electrical stimulus of the tooth pulp. The reflex EMG's were recorded from the digastric muscles. Single electroacupuncture stimulation (CS1) was delivered to the skin of a rat.
CS1 facilitated the reflex for 20ms after the stimulation, and then inhibited it from 40ms to 250ms. When CS1 was preceded by another electroacupuncture stimulation (CS2), the facilitatory effect induced by CS1 was enhanced CS2-CS1 interval being within 10ms. Then the reflex was inhibited when CS2-CS1 interval was 40-150ms. On the other hand CS1's inhibitory effect was suppressed by CS2 and the reflex reappeared while CS2 preceded CS1 at an interval of 100ms to 1.5s.
