The purpose of this study was to evaluate the effects of mental stress measured with heart rate variability(HRV) in healthy adults and to evaluate the effects of laserneedle acupuncture therapy in healthy adults. Methods : 25 healthy volunteers participated in this study. The volunteers were divided randomly, the real laserneedle acupuncture therapy group or the sham laserneedle acupuncture therapy group. First, After 5 minute rest, mental stress was given with stroop color word task and calculation task. And then laserneedle acupuncture therapy or sham laserneedle therapy was done on HT8(少府) for 15 minute. HRV was recorded in 3 period-before stress, after stress, and after laserneedle or sham acupuncture therapy. Results : LF was significantly increased after mental stress. And there was no significant difference between the real laserneedle acupuncture therapy group and the sham laserneedle acupuncture therapy group. Conclusions : This results show that mental stress-stroop color word test and calculation test for 10 minute- contribute to activation of the sympathetic nervous system.

Objective: The aim of this study was to investigate anti-ischemic effect of LR1 HT8 Reduction in Acupuncture Methods: I designed to investigate whether LR1 HT8 Reduction in Acupuncture affects cerebral hemodynamics [regional cerebral blood flow(rCBF), pial arterial diameter(PAD), mean arterial blood pressure(MABP)] in normal rats and to make manifest whether LR1 HT8 Reduction in Acupuncture is mediated by cyclooxygenase or guanylate cyclase. The changes of rCBF and MABP were determinated by laser-doppler flowmetry(LDF), and the change of PAD was de terminated by video microscope and width analyzer. Results: The results were as follows; 1. LR1 Reduction in Acupuncture was increased rCBF and PAD, but decreased MABP. 2. HT8 Reduction in Acupuncture was significantly increased rCBF, but decreased MABP, and increased PAD. 3. LR1 HT8 Reduction in Acupuncture was significantly increased rCBF, PAD, but decreased MABP after withdrawing of the needle. This results suggest that LR1 HT8 Reduction in Acupuncture increased significantly rCBF by dilating PAD. 4. Pretreatment with indomethacin(1mg/kg, i,v.) was significantly inhibited LR1 HT8 Reduction in Acupuncture induced increase of rCBF and PAD, but increased LR1 HT8 Reduction in Acupuncture induced decrease of MABP after withdrawing of the needle. 5. Pretreatment with methylene blue($10{\mu}g/kg$, i,v.) was decreased LR1 HT8 Reduction in Acupuncture induced increase of rCBF and PAD, but accelerated LR1 HT8 Reduction in Acupuncture induced decrease of MABP. Conclusions: I suggest that LR1 HT8 Reduction in Acupuncture has an anti-ischemic effect through the improvement of cerebral hemodynamics, and the mechanism is mediated by cyclooxygenase.

Objectives : The aim of this study was to examine the effect of electroacupuncture(EA) at an acupoint, HT8(Sobu), on normal humans by using power spectral analysis. We examined the effect on the Heart Rate Variability(HRV), and the balance of the autonomic nervous system. Methods : Thirty-two healthy volunteers participated in this study. EEG(Electroencephalogram) power spectrum exhibits site-specific and state-related differences in specific frequency bands. A thirty-two channel EEG study was carried out on thirty-two subjects(14 males; mean age=23.5 years old, 18 females; mean age=21.5 years old). HRV and EEG were simultaneously recorded before and after acupuncture. Results : In the ${\alpha}$(alpha) band, during the HT8-acupoint treatment, the power values in the ${\alpha}$(alpha) band significantly decreased(p<0.05) at 28 channels. In the ${\beta}$(beta) band significantly decreased(p<0.05) at 26 channels. In ${\delta}$(delta) band significantly decreased(p<0.05) at 18 channels. In ${\theta}$(theta) band significantly decreased(p<0.05) at 20 channels. ${\alpha}/{\beta}$ values were increased at 6 channels and decreased at 10 channels.${\beta}/{\theta}$ values were increased at 10 channels and decreased at 19 channels. Mean-RR(RR-interval), Complexity, RMSSD(Root mean square of successive differences), SDSD(Standard deviations differences between adjacent normal R-R intervals), norm HF showed a significantly increased and mean-HRV, norm LF, LHR(LF/HF Ratio) showed a significantly decreased after HT8-acupoint treatment(p<0.05). Conclusions : These results suggest that EA at the HT8 mostly causes significant changes on alpha(28 channels), beta(26 channels), delta(18 channels), theta(20 channels) bands and mean-HRV, mean-RR, complexity, RMSSD, SDSD, norm LF, norm HF and LHR. If practicing EA at the HT8, it will regulate the function of the cerebral cortex, decrease activity of the sympathetic and increase parasympathetic nervous activity.

There was a great problem about the deposition between materials of a different kind at the beginnings of the introduction of porcelains, however, thereafter the deposition efficiency was settlded to the sufficient level of all user thanks to effort to have studied by many scholars and clinical authorities. But in a clinical process, as the difference of designs has an effect on fractures of porcelains, this researcher divided them into 4 groups of A: 1 mm, B: 2 mm, C: 3 mm, and D: 4 mm, and made 40 pieces to each 10 as the test samples to consider a length axis of tooth for studies in accordance with a position of a finishing line to meet between porcelain and metal at the contact point at the adjacent side to a metal porcelain. The sample materials are those to be use at the open market and the test samples wer completed by the same manufacturing technique to that of existent metal porcelain tube. s a result of the strength test on fractures, the average value is as in the following, A: 1 mm - 8.5bar, B: 2 mm - 10.5bar, C: 3 mm - 14.3bar, and D: 4 mm - 15.0bar. In case of the metal porcelain tube, the more faraway to process parts of metal and porcelain from the contact point of adjacent side has the stronger strength of fractures, Accordingly, the research shows that it had better to keep off more than 3 to consider a ledngth axis of tooth.

Objectives : The aim of the present study is to observe effects of acupuncture related with the nerve system, Inferior mesenteric nerve activity(IMNA) was examined on BL60 acupuncture closely connected with the bladder and HT8 with little tied. Materials and methods : Acupunctures were performed during 100 seconds after stabilization. IMNA was measured by micromanipulator, preamplifier, mean arterial pressure(MAP) and heart rate were observed by blood pressure transducer, 4-channel transducer amplifier in anesthetized rat. Results : On BL60 acupuncture, the heart rate was not significantly decreased but IMNA, MAP were significantly decreased and Maximum peak of IMNA was increased during inserted acupuncture, decreased after ejected acupuncture respectively. On HT8 acupuncture, IMNA was decreased during acupuncture than before acupuncture but the others did not showed signigicant difference. Conclusions : Our results demonstrated a meridian interaction between BL60 acupoint in the bladder channel and Inferior mesenteric sympathetic nerve related to the bladder. This fact suggest that BL60 acupuncture have effect on the bladder through the nerve system. Meanwhile, IMNA was decreased during HT8 acupuncture. This result is supposed HT8 to have not meridian function but acupoint function by another mechanism. It needs to be closely examined other meridians and nerve by the optimal approaching method.

Objective : The purpose of this study was to investigate the Effect of Acupuncture Stimulation of Sohae(H3) and Sobu(H8) Acupoint on Skin Temperature of Sochung Acupint(H9, the end acupoint of Heart Meridian). Sohae and Sobu acupoint has a property of water and fire in the Five agents on Heart Meridian. Methods : Subjects were four healthy oriental medical students volunteers(male, mean age-28). One group(two subjects) received acupuncture on Sohae acupoint(H3) and the other group(two subjects) on Sobu acupoint(H8) while resting. Skin temperature was measured on Sochung acupoint(H9) before, during, and after acupunture stimulation. Each test took 15minutes. The initial 5minutes were definded as BAS(Before Acupuncture Stimulation) period, the following 5minutes as DAS(During Acupuncture Stimulation) period, the last 5minutes as AAS(After Acupuncture Stimulation) period. This test was performed twice in order to increase the statistical authenticity. Results : Our result indicates that acupuncrue stimulation of Sohae acupoint(H3) decreased and Sobu acupoint(H8) increased skin temperature on Sochung acupoint(H9) in the DAS period. The changes remained throughout the AAS period. Our conculusion are that stimulaton of the Water and Fire property-acupoint(H3, H8) on Heart changes the skin temperature on Sochung acupoint on the same Heart Meridian. However this study has no authenticity because it had no regard for many factors effecting on the result and the result of the study was the very reverse of our expectation.
