The aim of this study was to examine the effects of electroacupuncture(EA) at the PC6 (Naegwan) on normal humans using KarhunenLoeve decomposition method. Electroencephalogram(EEG) is a multi-scaled signal consisting of several components of time series with different dominant frequency ranges and different origins. EEG KarhunenLoeve decomposition method exibit site-specific and state-related differences in specific frequency bands. In this study, KarhunenLoeve decomposition method was used as a measure(D2) of complexity. 30 channel EEG study was carried out in 10 subjects (10 males; $age=21.4{\pm}0.5$ years). Results : We found that the average values and standard deviations of D2 at FP1, FP2, FTC1, FTC2, TT1, TT2, T4, TCP1, P3, P4, T6, OZ channel (p<0.05) were higher than during the acupuncture treatment, and the average values and standard deviations of D2 at F3, F8 channels(p<0.05) were lowered than during the acupuncture treatment. However, the comparison with that before and after the treatment shows no significant differences in all channels.

Objectives : This study was to evaluate inhibitory effects of Naegwan-acupuncture($PC_6$) on acute RE(reflux esophigitis) rat induced by pylorus and forestomach ligation operation. Methods : Twenty seven SD rats were divided three groups (intact normal rat; RE control rat; RE control rat respectively stimulated by Naegwan point($PC_6$)). All rats was fasted for 18 h but free water, we induced RE by pylorus and forestomach ligation operation. Six hour after the operation, rats were sacrified, collected bloods in the abdominal vein, dissected a esophagus and stomach. The stomach was washed a 1 ml PBS to research gastric volume, pH, acidity and mucin release of gastric juice, esophagus was cut longitudinally and pictured a innter mucosa area to research damages in esophagus. The proinflammatory cytokine and chemokine including IFN-${\gamma}$, TNF-${\alpha}$, IL-$1{\beta}$, IL-6 and MCP-1 were analyzed by ELISA kit. Results : 1. Significantly, death rate of $PC_6$ acupuncture rat group was decreased compared to that of RE control group. 2. Gastric Volume, gastric injury and esophageal mucosa demage were decreased significantly, too. 3. Compared with RE, all of the proinflammatory cytokine and chemokine analyzed in serum of $PC_6$ were decreased remarkably. Especially, there were significant meanings TNF-${\alpha}$, IL-6 and MCP-1 in serum of $PC_6$ were decreased. Conclusion : The results suggest that antiinflammatory and protecting effects of PC6 could attenuate the severity of reflux esophagitis and prevent the esophageal mucosal damage, and validate its therapeutic use in esophageal reflux disease.

Objectives : This studies were performed to investigate the correlation between the treatment effects and the changes of the thermal differences at the pre and post-treatment by using the digital infrared computer thermographic imaging (D.I.T.I) to the irritable colon syndrome 30 patients. Methods : The extracts of the gwakhyangjunggisan were administerd to the patients by oral method three times per day during four weeks. we selected the Chung-Wan($CV_{12}$), Chunchu($S_{25}$). Hapkok($LI_4$), Naegwan($P_6$), Yongdo($H_4$) acupoints and treated the patients two times per week during four weeks. One week later, we investigated the changes of the pressure pain around left side Pokkyol($SP_{14}$), the symptoms. and the skin temperature changes on Pokkyol($SP_{14}$) and Kimun($LR_{14}$) around, by using the D.I.T.I. Results : In the correlation between the severity of the pressure pain around left side Pokkyol($SP_{14}$) and the thermal differences on Pokkyol($SP_{14}$) and Kimun($LR_{14}$) around, before the treatment, the more the pain was severe, the more the skin temperature was differential significantly. In the correlation between the severity of the symptoms and the thermal differences on Pokkyol($SP_{14}$) and Kimun($LR_{14}$) around, before the treatment, the more the symptom was severe, the more the skin temperature was differential significantly. In the changes of the pressure pain around left side of Pokkyol($SP_{14}$), the improved were significantly higher than the unimproved. In the changes of the symptoms, the improved were significantly higher than the unimproved. In the correlation between the changes of the pressure pain around left side Pokkyol($SP_{14}$) and the changes of the thermal differences at the pre and post- treatment, the more the pain was improved, the more the thermal change was widened significantly. In the correlation between the changes of the symptoms and the changes of thermal differences at the pre and post-treatment, the more the symptom was improved. the more the thermal change was widened significantly. Conclusions : Above the results, the treatments was effective and the digital infrared computer thermographic imaging (D.I.T.I) was useful to prove the improvements of the pressure pain and the symptom with the irritable bowel syndrome patients.
