CONCLUSION
The present study was designed to observe (1) whether electrical stimulation at
acupuncture point could produce antinociceptive effects on oral pain ; (2) whether the
antinociceptive effects could be blocked by intraperitoneal injection of the opioid receptor
antagonist naloxone. The analgesic effect of acupuncture was estimated by the degree of
the jaw opening reflex evoked by noxious electrical stimuli around mental foramen
which was measured by the digastric muscle electromyogram.
Experiments were carried out with 34 rats weighing 180-200g anesthetized with intra
peritoneal urethane in an initial dose of 0.15g/l00g. A pair of stimulating electrodes were
inserted into the area around mental foramen for noxious stimulation. Rectangular
constant current pulses(100¥ìsec duration, 2Hz) with intensity of about 2 times threshold
for evoking the jaw opening reflex. Anterior belly of digastric muscle was exposed and
a pair of 0.1§® wire electrodes were inserted for EMG recording. The magnitude of the
jaw opening reflex was estimated by averaging the amplitudes of digastric EMG
measured from oscilloscope. Surface electrode was located on the acupuncture point
Zusanli for acupuncture stimulation(100¥ìs, 5V, 2§Ô). This stimulation was maintained for
20min. Weak muscular contractions were being elicited during the stimulation. Naloxone
hydrochloride(0.2§·/§¸)was given intraperitoneally.
The analgesic effect of electroacupuncture stimulation on oral pain was found
markedly in group I and ¥±, and also observed in group ¥². That kind of analgesic
effect was blocked by naloxone application in NX in group ¥± and in NXEA20 in group
¥² as compared with EA in group I or ¥±.
In regard to abode results, stimulation of Zusanli resulted in reducing the amplitude of
digastric EMG and these effects were inhibited by naloxone. It implies that effects of
acupuncture stimulation on analgesia is mediated by endogenous opioid.
