Objectives : This study was designed to investigate the effects of bee venom acupuncture at Shinsu($BL_{23}$) and Daejangsu($BL_{25}$) on neuropathic pain induced by tibial and sural nerve injury in rats. Methods : Neuropathic pain model was made by partial resection of tibial and sural nerve. Three weeks after the neuropathic surgery, bee venom acupuncture was firstly injected at $BL_{23}$ and $BL_{25}$, then we measured withdrawal responses induced by von Frey filament and acetone stimulation. Bee venom acupunctures were injected 6times on every 2days. Measurement of withdrawal responses were conducted on the same days. After bee venom acupuncture injection, expression levels of c-Fos, nocieptin and KOR-3 were observed through using immunohistochemistry. Results : In this experiment, bee venom acupunctures at $BL_{23}$ and $BL_{25}$ decreased levels of withdrawal responses induced by von Frey filament and acetone stimulation respectively. In addtion, expression levels of c-Fos, nociceptin and KOR-3 in central gray part of brain in rats were decreased by bee venom acupuncture. Conclusions : These results imply that bee venom acupuncture was useful to treat patients with neuropathic pain, and related mechanisms were involved in opioid and their receptors such as nociceptin and KOR-3.

The pain was induced on upper and lower incisor of the rat based on the theory of 'connections of upper incisor pain with stomach meridian and lower incisor pain with large intestine meridian'. Such acupoints as ST36 and LI4 were used for alleviation of upper and lower incisor pain. The digastric myogram (dEMG) was utilized for the pain measurement. The upper incisor pain was gradually decreased during ST36 stimulation and significant differences were observed at 20 and 25 minute point during 60 minutes study. The upper incisor pain was gradually decreased during LI4 acupuncture and 20 minute was the only point that showed a significant difference. The alleviation of lower incisor pain was not obvious during the ST36 acupuncture. The lower incisor pain was gradually decreased during LI4 stimulation with significant differences at 15, 20 and 40 minute point. In conclusion, the upper incisor pain was relieved with ST36 and LI4 acupuncture while LI4 was effective on the lower incisor pain alleviation based on the theory of 'connections of upper incisor pain with stomach meridian and lower incisor pain with large intestine meridian'.

This study was performed from October 1997 to March 1998 on 42 healthy students to observe the effects of acupuncture at Hap-kok (LI4) according to the meridian and qi-xue(氣血) phenomenon of oriental medicine's theory. Skin temperature on the Kok-Chi(LI11) and Yong-Hyang(LI20) were measured by D. I. T. I. (Digital Infrared Thermograph Imaging) before acupuncture stimulation, 1min after and after acupuncture stimulation during 10 min. 1. In healthful man, average skin temperature about Kok-Chi area was in low than Yong-Hyang, and temperature change for 10 min was decreased significantly. 2. In Kok-Chi, the temperature decrease index of execution was shown in low than control. 3. When the temperature of Yong-Hyang(left) was higher, the index was shown in high than control. 4. When the temperature of Kok-Chi (left) was higher, execution temperature change was decreased significantly than control. The above results indicates that D. I. T. I. was a useful method to observe follow-up the effects and changes by acupuncture stimulation on objective evaluation of phenomenon for the meridian system. Thus, acupuncture on LI4 affects to thermal changes of ST25 and LI4, but exact examination of thermal changes on ST25 will have to be.

Objectives : The aim of this study was to investigate the effect of various electroacupuncture stimulation on neuronal nitric oxide synthase(nNOS) in cerebral cortex, brain stem, cerebellum of spontaneously hypertensive rats. Methods : We evaluated the changes of nNOS-positive neurons using a immunohistochemical method. The staining intensity of nNOS positive neurons was assessed in a quantitative fashion using a microdensitometrical method based on optical density by means of an image analyzer. Results : The average optical density of nNOS-positive neurons of 100 Hz (bipolar square wave 0.2 ms duration and 100 Hz frequency) electroacupuncture treatment group significantly decreased in most cortical areas comparison between the manual acupuncture and 2 Hz (bipolar square wave 0.2 ms duration and 2 Hz frequency) electroacupuncture groups. In the brain stem, the optical density of nNOS-positive neuron at superficial gray layer of the superior colliculus area, dorsolateral periaqueductal gray area and paralemniscal nucleus were same as cerebral cortex. Conclusion : We conclude that the morphological evidence for nNOS-positive neurons may be have regional change in cerebral cortex brain stem and cerebellum according to various electroacupuncture stimulations.

Objective : The role of high frequency 120 Hz electroacupuncture(EA) in carrageenan-induced pain was studied by examining the alnalgesic effects, and prostaglandin $E_2(PGE_2)$ levels measurement and spinal N-methyl-D-aspartate(NMDA) receptor expression. Inflammation was induced by an intraplantar injection of 1% carrageenan into the right hind paw. Method : Bilateral EA stimulation with 120 Hz were delivered at those acupoints corresponding to Zusanli and Sanyinjiao in man via the needles for a total of 30 min duration in carrageenan-injected rats. Results : EA stimulation showed significant analgesic effects as measured by analgesy-meter at all time points tested compared with controls. Three hours after carrageenan injection, PGE2 levels were measured by commercial kit. EA significantly inhibited PGE2 production in the right paw. The number of NR1 and NR2A, NMDA receptor, immunoreactive neurons was significantly increased in the superficial dorsal horn(laminae I-II) and nucleus proprius(laminae III-IV) of ipsilateral spinal cord at L4-5. But the number of carrageenan-induced NR1 and NR2A immunoreactive neuron, especially NR1 immunoreaction in the superficial dorsal horn, was reduced by 120 Hz EA stimulation. Conclusions : These results indicate that NMDA receptors may mediate transmission of nociceptive information originating in tissue inflammation of hind paw and high frequency 120 Hz EA stimulation have an alleviating action against local inflammatory pain.

Acupuncture and Low-frequency-wave stimulation at the Points (LI4, LI6, LI8 and LI11) on the large intestine meridian of hand resulted in same pattern about body temperature profiles with time. Upon 4Hz and 50Hz stimulation the temperature profiles on LI6 and LI11 were declined probably because of their relationship with Proprioceptive activity. Temperature different at the points was higher when the intensity of low-frequency-wave stimulation was stronger.

This study was designed to evaluate the analgesic effect of low power GaAsAl laser on the pain threshold of mechanical stimulation using different treatment points, acupuncture point (zusanli) and non-acupuncture points(back). Furthermore, we investigated the analgesic effect of low power GaAsAl laser using the different duration and intensity of laser in mechanical stimulation induced pain behavior. The results were summarized as follows: 1. The threshold of mechanical stimulation was significantly increased by GaAsAl laser stimulation into zusanli point after 15 and 30 min after laser stimulation(P<05). However, the laser stimulation into non-acupoint did not affect the pain threshold of mechanical stimulation. with dose dependent manner. 2. In order to investigate the analgesic effects of BV depending upon different intensities of laser stimulation, the experimental animals were divided into three groups: 3 mW treated group, 6 mW treated group and 10 mW treated group. The low power GaAsAl laser stimulation was applied into zusanli acupoint for 30 min with different intensity of laser stimulation. Six and ten mW of laser stimulation significantly increased the pain threshold of mechanical stimulation at 15 min after laser stimulation as compared to that of control group(P<.05). Moreover, the analgesic effect of 10 mW laser stimulation was maintained for 30 min after laser stimulation (P<.05). 3. Finally, we tested the analgesic effect of 10 mW laser stimulation using different duration such as 10 min, 30 min or 1 hr after application of mechanical stimulation. In 30 min treatment group, the pain threshold of mechanical stimulation was increased at 15min and 30min after laser stimulation(P<.05). However, laser stimulation for 60 min dramatically increased the pain threshold of mechanical stimulation at 0 min after laser stimulation and the analgesic effect of laser stimulation was observed until 1 hr after laser stimulation. In conclusion, these data apparently demonstrate that low power GaAsAl laser has analgesic effect on mechanical induced pain model in rats. In addition, the treated point, intensity and duration of laser stimulation should be concerned before clinical application for pain management purpose.

This study was undertaken to determine effect of Zusan1i(ST36) acupuncture (AP) on the small intestinal motility in the rabbit. Changes in the motility in vivo of ileum was measured before and 20 min. after AP. In order to examine whether AP effect was affected by autonomic nerves, norepinephrine or acetylcholine was applicated. AP significantly increased the mean wave amplitude and motor index, but not the mean wave duration and motor activity. Infusion of norepinephrine ($2{\mu}m$) into an ear vein resulted in a decrease in the mean wave amplitude and motor index, which was not affected by AP. Acetylcholine ($10{\mu}m$) produced inhibition followed by stimulation of motility. The stimulation of motility was induced by an increase in the mean wave amplitude and motor index, but not the mean wave duration and motor activity. The effect of acetylcholine was not significantly different between before and after AP. These results suggest that Zusan1i(ST36) acupuncture stimulates the small intestinal motility, which is not mediated by autonomic nerves. Therefore, Zusan1i(ST36) acupuncture seems to be applicable to impaired small intestinal movement.
