The purpose of this study was to investigate the effect of various electroacupuncture
duration induced by acupuncture point-Zusanli (S36) electrical stimulation
on inhibition of amplitude of digastric electromyogram (dEMG) evoked by noxious
electrical stimuli around the mental foramen. (SD) were anesthetized with> intraperitoneal sodium pentobarbital in an initial dose of
50mg/kg and maintenance doses of 4.5mg/kg/h were given through a cannula in the
femoral vein using a constant infosion pump. A pair of stimulating electrodes were
inserted for noxious stimuli around the mental foramen. An irritant electronic stimuli
pulse (0.2 Hz, 0.1 ms duration) was produced with an intensity of about 1.5¡­2 times
threshold for evoking the dEMG. The anterior belly of the digastric muscle was exposed
and a pair of 0.1mm wire electrodes were inserted for dEMG recording. Acupuncture
point stimulation on Zusanli (2 Hz, 250 ¥ìs, biphasic pulse, 2V) was delivered by Dental
Electronic Anesthesia (3M, U.S.A). For periods of electronic stimulation of 10, 20, and
30min, the amplitudes of dEMG were measured on the oscilloscope and on the monitor
connected to the amplifier. The following results were obtained : The dEMG was
decreased to 73.4% of that in the control set after 10 min electtroacupunture stimulation
(Group I ) ; The dEMG was decreased to 77.1% (10min), 54.0.% (20min) of that in the
control set after 20minutes of electroacupunture stimulation (Group ¥±). The dEMG was
decreased to 73.3% (10min), 61.9% (20min), 76.2%(30min) of that in the control set after
30 min of electroacupunture stimulation (Group ¥²). From these results, it may be that
in the electroacupuncture stimulation on the Zusnali resulted in a reduction of amplitude
of dEMG and that the most effective electroacupuncture stimulation period was 20min.
