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.

Acupuncture treatment cures disease by regulating the functional excessiveness or deficiency which occurs in the meridian and visceral organs, and by letting stagnated Qi and Blood flow through the whole body and then controlling Qi. Whether or not to have Qi feeling is the main factor needed to manifest the efficacy of acupuncture. So it needs the very stimulus to make Qi felt rather than the simple stimulus. In order to have Qi feeling, it needs to acupuncture a patient according to patient's thinness or fatness, constitution, richness or poverty and age. And also it needs to vary the way to acupuncture a patient according to meridian, kinds of pulse, degrees of disease, new or old diseases, seasons with a disease and local areas of disease. In order to ascertain that it is important for the quality and quantity of acupuncture stimulus and the state of feeling acupuncture to get the efficacy of acupuncture, the experiment was planned to confirm whether the form and Qi of subject has different result according to the stimulated duration and depth. On the basis of the report that acupuncture on derma, when using electroacupuncture at Zusanli(ST 36) which denotes small intestinal motility, is more efficient than full depth acupuncture, I got the following result, after I observed whether the stimulated duration and depth give different efficacy according to the sex and weights of rat in experiment. The increased effects of small intestinal motility by electroacupuncture on Zusanli(ST 36) appeared after stimulating full depth for thirty minutes without distinction of sex and weights. This significant change was observed only in the female experimental group when I distinguished the sex. The small interstinal motility in rats by electroacupuncture at zusanli(ST 36) decreased in the 10 minutes' stimulated group and 30 minutes' stimulated group by duration on the one hand, and derma-deep stimulated group and full depth stimulated group by the depth of stimulus on the other hand, as the weights increased. This result shows that the duration and depth of acupuncture depends on the differences of acupuncture points, sex of the experimental animals, ages, and, weights. And the further study on the experimental and clinical differences and sextual differences need to be continued on.

Objectives: The purpose of this study was to investigate the differences in kind, intensity and depth of de Qi sensation by patients' gender, age, BMI and sensitivity. Methods: Sixty-four healthy volunteers (mean age $26.51{\pm}4.72$, range 22-39) who had been studying anatomy, meridianology, acupuncture & moxibustion for more than five years at Dongguk University, Go-yang, Korea, were invited to take part in an investigation of the sensations associated with acupuncture needling. Needling was self-administered on Hegu (LI4) in the hand and Zusanli (ST36) in the leg randomly. After obtaining de Qi, the participants were asked the kind, intensity and depth of de Qi sensation. Results: There was no statistically significant difference in the kind of de Qi sensation found by acupoints and needling methods (p>0.05). Hegu (LI4) was found to be significantly higher in the intensity (p<0.001), and the depth of de Qi sensation was significantly higher in Zusanli (ST36) than Hegu (LI4) (p<0.001). There was statistically significant difference found in the intensity of de Qi sensation by depth and sensitivity (p<0.05). In the depth of de Qi sensation, there was statistically significant difference found by sensitivity (p<0.05). In de Qi sensation of practitioners, there was statistically significant difference found by gender, BMI, the intensity of de Qi sensation (VAS) and sensitivity. Conclusions: Further study involving acupuncture de Qi sensation and the influencing factors is needed.

Ischemia that causes stroke induces inflammation of brain cells and apoptosis and as a result, it influences much on the functional part of a man. The needle electrode electrical stimulation (NEES) that combines acupuncture of oriental medicine with electric therapy of western medicine relieves inflammation of cells and has effect on regrowth of nerve tissues. This study was conducted to verify the influence of NEES on the occurrence of c-Fos of cerebrum after applying NEES to the meridian point, Zusanli (ST 36) of a rats with induced ischemia. Global ischemia was induced by using ligation method on common carotid artery of male Sprague Dawley (SD) rats. The ligation was maintained for 5 minutes and then suture was removed for blood reperfusion. After inducing global ischemia, NEES was done to the left and right meridian points of Joksamri of a rat for 30 minutes after 12 hours, 24 hours, and 48 hours. The findings were as follows. 1. In the result of immunohistochemical method, the number of c-Fos immune response cells significantly decreased (P<.05) in NEES group than the control group (GI) that did not get NEES. 2. In the result of western blotting, the occurrence of c-Fos after 24 hours from the inducement of ischemia significantly decreased (P<.05) in NEES group than the control group (GI) that did not get NEES. Therefore, as the effect of NEES was shown highest after 24 hours from the ischemia, it is suspected that NEES would take important role in early treatment after cerebral stroke.

Objective : The purpose of this study is To investigate the effects of acupuncture and moxibustion at Zusanli(ST36) and Weishu(BL21) Methods : serum gastrin level by radioimmunoassay was measured at 5 days after acupuncture and moxibustion of those acupoints. Gastric endocrine cell(G cell and Histamine immunoreactive density) by avidin-biotinylated complex(ABC) technique, histological examinations(Alcian Blue-PAS Stain; Alcian blue-Periodic Acid Schiff reagent) of the gastric mucosa were also performed. Acupuncture applied to the ST36 acupoint increased gastrin level of serum, but moxibustion did not produced significant effect. All of acupuncture and moxibustion at BL21 acupoint increased gastrin level of serum significantly. In moxibustion at ST36 and BL21, the number of gastrin secreting cells in gastric mucosa, the density of immunoreactive histamin secreting cells and the density of body mucosa stained by PAS were decreased compare to acupuncture at ST36 and BL21. In acupuncture and moxibustion at BL21, the density of pylorus mucosa stained by PAS were increased compare to the groups applied to ST36. In the density of body mucosa stained by AB, moxibustion at BL21 and ST36 were increased compare to the other groups. Results : These data suggest that acupuncture and moxibustion at BL21 increased gastrin level of serum and those effects were more potent than acupuncture at ST36.

Electroacupuncture(EA) is known to affect various autonomic functions such as blood pressure regulation, immune modulation and the improvement of disorders concerning autonomic functions. The aim of the present study was to establish whether EA has an immune-enhancing effect. ICR mice weighing 20 to 25g were divided into four groups: Group I(n=6), blank; Group II(n=6), control; Group III(Zusanli, n=6), low frequency-EA(10Hz of electrical stimulation), and Group IV(Zusanli, n=6), high frequency-EA (100Hz of electrical stimulation). For this study, we investigated expressions of spleen heat shock protein (HSP)70, HSP90 and secretions of cytokines. A Forced Swimming Test(FST) was performed as a model of activity test in mice. After three days of the FST, 10Hz EA($114.8{\pm}7.27s$) and 100Hz EA($147.5{\pm}1.29s$) immobility time significantly decreased compared with the control group($157.2{\pm}1.48s$). After seven days, 10Hz EA($124{\pm}1s$) and 100Hz EA($141{\pm}4.24s$) also significantly decreased immobility time compared with the control group($168{\pm}7.93s$). 10Hz EA and 100Hz EA increased the expression of HSP70 but did not change that of HSP90. 100Hz EA increased secretions of IL-6 and IL-12 compared with the control group however, 10Hz EA failed to change those of IL-6 and IL-12. The present results suggest that EA may be useful for down-regulated immune diseases.

Neuropathic pain syndromes resulted from peripheral nerve injury appear to be resistant to conventional analgesics like opioids. However, it has been demonstrated that acupuncture including aqua-acupuncture may be effective in managing neuropathic pain. The present study was conducted to determine if bee venom injection into acupoint ihibits neuropathic pain, which is difficult to be treated by usual analgesics. Under pentobarbital anesthesia, male Sprague-Dawley rats were subjected to neuropathic surgery. Two weeks after nerve injury, mechanical and cold allodynia were tested in order to evaluate the antiallodynic effects of bee venom injection into an acupoint. Intraperitoneal injection of morphine inhibited mechanical allodynia dose-dependently. Bee venom injected into Zusanli acupoint significantly inhibited mechanical and cold allodynia. These results suggest that bee venom-acupuncture as well as morphine is very effective to inhibit mechanical allodynia.

Objectives : The present study was conducted to evaluate the analgesic effects of automatically controlled heating acupuncture(ACHA) using 2 different pain models(acute pain and neuropathic pain) and 2 different stimulation conditions (heating $41.5^{\cdot}C$ and heating $44.5^{\cdot}C$) in Sprague-Dawley rats. Methods : Tail flick latency(TFL) to a noxious radiant heat stimulus in lightly anesthetized rats was measured before and after ACHA stimulation for 5-min at the Zusanli(ST36) acupoint. For the neuropathic surgery, the right superior caudal trunk was resected at the level between S1 and S2 spinal nerves innervating the tail. Two weeks after the nerve injury, ACHA stimulation($41.5^{\cdot}C$ or $44.5^{\cdot}C$) was delivered to Zusanli(ST36) for 5 min. The behavioral signs of warm allodynia were evaluated by the tail immersion test (i.e. immersing the tail in warm $water(40^{\cdot}C)$ and measuring the latency to an abrupt tail movement) before and after the ACHA stimulation. Results : In the TFL test, ACHA stimulations under both the conditions above produced more potent analgesic effects than plain acupuncture(PA, acupuncture needle insertion only) and control(no treatment). In the tail immersion test, ACHA stimulations under all of the conditions had markedly relieved the warm allodynia signs. Conclusion : Automatically controlled heating acupul1cture produced analgesic effecs in acute and neuropathic pains.

The majority of strokes are caused by ischemia and result in brain tissue damage, leading to problems of the central nervous system including hemiparesis, dysfunction of language and consciousness, and dysfunction of perception. The purpose of this study was to investigate the effects of Poly(ADP-ribose) polymerase(PARP) on necrosis in neuronal cells that have undergone needle electrode electrical stimulation(NEES) prior to induction of ischemia. Ischemia was induced in male SD rats(body weight 300g) by occlusion of the common carotid artery for 5 min, after which the blood was reperfused. After induction of brain ischemia, NEES was applied to Zusanli(ST 36), at 12, 24 and 48 hours. Protein expression was investigated using immuno-reactive cells, which react to PARP antibodies in cerebral nerve cells, and Western blotting. The results were as follows: In the cerebral cortex, the number of PARP reactive cells after 24 hours significantly decreased(p<.05) in the NEES group compared to the GI group. PARP expression after 24 hours significantly decreased(p<.05) in the NEES group compared to the GI group. As a result, NEES showed the greatest effect on necrosis-related PARP immuno-reactive cells 24 hours after ischemia, indicating necrosis inhibition, blocking of neural cell death, and protection of neural cells. Based on the results of this study, NEES can be an effective method of treating dysfunction and improving function of neuronal cells in brain damage caused by ischemia.

Acupuncture works by stimulating peripheral sensory nerves and their endings causing an increase in cutaneous blood flow and microcirculation, as well as release of neurotransmitters, neuropeptides, and hormones. SP6 Patch is a nanoscale nontransdermal device that mildly stimulates Stomach 36 (zusanli) and other acupuncture points. As stimulation of these points has been indicated to have an effect on hypothalamic function, it is of great research interest to investigate the effect of SP6 Patch on the physiology of organs that are affected by hypothalamic regulation. Bioelectrical tissue impedance data indicative of cellular physiologic organ function, using an Electro Interstitial Scan (EIS) system, were acquired from hypothalamus, pancreas, liver, intestines, kidneys, thyroid and adrenal glands in 10 (1 male, 9 females) volunteers while wearing the SP6 Patch daily for 1 week. EIS testing was performed at baseline with no patch, 30 min after wearing the patch, and after wearing the patch 12 h/day for 1 week. Subjects were instructed to keep well hydrated during the study period. All subjects served as their own control. The hypothesis was: The SP6 Patch worn 12 h/day on the Stomach 36 acupuncture point for 1 week, may significantly improve cellular physiologic functional status of different organs measured by EIS. All tested organs achieved significant improvement in their functional physiologic status after wearing the SP6 Pach 12 h/day for 1 week compared to baseline with an overall average statistical power > 89%. Based upon these results the hypothesis was accepted as true.
