  • Objectives: Pulse-Respiration Ratio has been used for estimating subject's Han-Yeol [寒熱] status since it mentioned in suwen [素問]. In practicing Pulse-Respiration Ratio over 5 means the status of Yeol [熱], Pulse-Respiration Ratio below 3 means the status of Han [寒]. We performed this study to examine the Optimum Standard for Measuring Pulse-Respiration Ratio on the Basis of Repeatability and Reproducibility. Methods: After subject's 5 minutes rest we measured subject's ECG, respiration pattern, EEG, EMG simultaneously. In this research examiner's number is two, subject's number is four, and the number of repeat is two. We calculated Pulse-Respiration Ratio through dividing Respiration cycle average by Pulse cycle average according to each standard including time section, $EEG(relative-{\alpha}$ density, $relative-{\beta}$ density, ${\alpha}/{\beta}$ and EMG. We analyzed these data through Gage R&R study using MINITAB 13.20 program and considered the results of below 30 %R&R and over 4 Number of Distinct Categories to have a significance. Results: 1. In the applying of time standard, Pulse-Respiration Ratio from section 3, 4, 6, 8 had a significant meaning in the aspect of Repeatability and Reproducibility. 2. In the applying of $EEG({\alpha}$ I , ${\beta}$ I , ${\alpha}/{\beta})$, EMG(E I) standard, there was no significant results. 3. In the applying of time standard(section 5, 6, 7), $EEG({\alpha}$ I , ${\beta}$ I , ${\alpha}/{\beta})$ and EMG(E I) standard simultaneously, Pulse-Respiration Ratio from ${\alpha}/{\beta}$ in section 6, ${\beta}$ I in section 8 had a significant meaning in the aspect of Repeatability and Reproducibility. Conclusions: We can suggest the Optimum Standard for Measuring Pulse-Respiration Ratio on the basis of Repeatability and Reproducibility as followings; 1. Pulse-Respiration Ratio Measuring time should be at least 15 minutes. 2. Applying of time(section 6, 8) and $EEG({\beta}$ I, ${\alpha}/{\beta})$ standard simultaneously is recommended considering reliability and validity but more study is needed. 3. EMG(E I) may be helpful to detect the segment of physical rest and exclude artifacts but more study is needed.

  • This study was to examine the positive and negative affect related to psychological characteristics of each Sasang types using Positive and Negative Affect Schedule (PANAS) with 78 students from School of Korean Medicine, Pusan National University. After determining the Sasang types by QSCC II, the psychological characteristics of each Sasang types were analysed by PANAS. We did ANOVA analysis with eight related scales and found significant differences between the Tae-Eum type ($18.71{\pm}8.75$, $6.47{\pm}3.36$, $6.31{\pm}2.47$, $3.18{\pm}2.77$, $10.94{\pm}10.08$) and the So-Eum type ($13.38{\pm}6.03$, $4.55{\pm}2.23$, $4.19{\pm}2.16$, $5.81{\pm}4.20$, $1.83{\pm}9.17$, respectively) in Positive Affect (PA) (F=3.931, p=0.024), PA-Joy (F=3.991, p=0.023), PA-Interest (F=5.025, p=0.009), NA-Afraid (F=3.118, p=0.050), and Difference between Positive and Negative Affect (DPN) (F=6.355, p=0.003) scores. The post-hoc analysis showed that the Tae-Eum type ($18.71{\pm}8.75$, $6.47{\pm}3.36$, $6.31{\pm}2.47$, $10.94{\pm}10.08$) has significantly higher score than So-Eum type ($13.38{\pm}6.03$, $4.55{\pm}2.23$, $4.19{\pm}2.16$, $1.83{\pm}9.17$, respectively) in PA (p=0.018), PA-Joy (p=0.021), PA-Interest (p=0.017), and DPN (p=0.002) scores. The So-Eum type ($5.81{\pm}4.20$) showed significantly (p=0.047) higher score than the Tae-Eum type ($3.18{\pm}2.77$) in NA-Afraid. Results demonstrated distinct affect profile differences between Tae-Eum and So-Eum Sasang types using PANAS. This study may serve as the foundation in identifying psychological traits of Sasang types, especially regarding the aspect of affect.

  • Oriental Diagnosis System(ODS) is an artificial intelligence program that utilize entered diagnosis knowledge, determine patient's disease and decide right medicine. The purpose of this study is to find a correlation between pattern Identification in Korean medicine and each sasang types(Tae-Eum and So-Yang) by analyzing ODS diagnosis result. Eventually our study secure availability of using ODS program at clinical training or developing diagnosis program. Subject of this study is 50 patients who was performed Sasang constitution diagnosis (28 patients were Tae-Eum and 22 patients were So-Yang). We analyize patient's diagnosis records by using ODS program and obtained result about pattern Identification. We used SPSS statistics 23 in analyzing the differences of the scores of Eight Principle Pattern Identification, Qi-Blood Pattern Identification, and Bing-xie Pattern Identification in each Sasang types (Tae-Eum, So-Yang). The Heat and Heat-moisture scores were significantly different(p<0.05) and Qi-Blood Pattern Identification scores were not different in each Sasang types(p>0.05). And Weight was significantly different in each Sasang types(p<0.05). It is hard to generalize the result because subject of this study was not enough and had sample speciality(tinnitus patients). However, we explained correlation between pattern Identification in korean medicine and each sasang types based on quantifiable and objective evidence system. it can be used at education of korean medicine and evidence of practice diagnosis. Futhermore, there have been no studies about anaylizing correlation between pattern Identification in Korean medicine and each sasang types using ODS program. So it is worthy of being utilized at clinical evidence data of ODS program.

  • Objectives : The purpose of this study was to examine the effects of Alisma canaliculatum Extract (ACE) on pacemaker potentials of small and large intestinal interstitial Cells of Cajal (ICC) in mice. Methods : We used enzymatic digestions to dissociate the ICC in the small and large intestine in mice. The whole-cell patch-clamp method was used to record pacemaker potentials in ICC. Results : 1. The ICC generated the pacemaker potentials in small intestine in mice. ACE (0.1-1mg/ml) induced membrane depolarization and decreased frequency with concentration-dependent manners. 2. Pretreatment with a Ca2+ free solution, Na+ 5 mM solution or 2-APB, a nonselective cation channel blocker, stopped the small intestinal ICC pacemaker potentials. In the case of Ca2+-free solution, Na+ 5 mM solution or 2-APB, ACE had no effects on the membrane depolarizations in small intestinal ICC. 3. The ICC generated the pacemaker potentials in large intestine in mice. Membrane depolarization appears regularly in the small intestine, but irregularly in the large intestine. ACE induced membrane depolarization (0.1-1mg/ml) and increased frequency (0.1-0.5mg/ml). 4. Pretreatment with a Ca2+ free solution, Na+ 5 mM solution or 2-APB, stopped the large intestinal ICC pacemaker potentials. In the case of Ca2+-free solution, Na+ 5 mM solution or 2-APB, ACE depolarized the membrane depolarizations in large intestinal ICC. 5. In mice, intestinal transit rate (ITR) values were dose-dependently decreased by the intragastric administration of ACE. Conclusions : These results suggest that ACE can regulate the pacemaker activity of ICC and the reaction by ACE is different from the small and large intestinal ICC, and the control of the intestinal motion by ACE may be caused by many complex processes.

  • Objectives : The purpose of this study was to examine the effects of herbal medicines on pacemaker potentials of large intestinal interstitial Cells of Cajal (ICC) in mice. Methods : We made the ICC culture in large intestine in mice and used the electrophysiological method to record pacemaker potentials. Also we used MTT assay to check cell viability and examined the ICC protein expression by western blot. Results : 1.Glycyrrhiza uralensis Fischer (GF) (50-150 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC50 is 58.95 ㎍/ml. Angelica gigas (AG) (50-200 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC50 is 77.22 ㎍/ml. Poncirus fructus (PF) (10-100 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC50 is 13.39 ㎍/ml. Citrus unshiu S. Marcov. (CU) (10-500 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC50 is 139.80 ㎍/ml. Gardenia jasminoides J. Ellis (GJ) (100-500 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC50 is 78.70 ㎍/ml. Coptis chinensis (CC) (100-1000 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC50 is 138.10 ㎍/ml. Scutellaria baicalensis (SB) (10-100 ㎍/ml) had no effects on pacemaker potentials and decreased frequency with concentration-dependent manners. IC50 is 18.34 ㎍/ml. Atractylodes macrocephala koidzumi (AM) (10-100 ㎍/ml) induced pacemaker hyperpolarizations and decreased frequency with concentration-dependent manners. IC50 is 18.54 ㎍/ml. 2. PF, SB and AM had no effects on cell death in large ICC. 3. PF increased the ANO1 and c-kit protein expression and SB and AM increased the c-kit protein expression in large ICC. Conclusions : These results suggest that PF, SB, and AM are likely to be the optimal combination of herbal medicines that can be used to treat diseases such as gastrointestinal motility disorders such as irritable bowel syndrome.

  • Objectives The purpose of this study is to understand formation courses of the ten types of LBP (十種腰痛) in Korean medicine through reviewing classic literatures. Methods We summarized sentences describing syndrome differentiation of LBP directly in Uibujeonrok (醫部全錄) and Donguibogam (東醫寶鑑), and then organized similarities and differences among diagnostic factors described in the classic literatures. Results In most of the classics LBP was classified according to the cause but the causes varied depending on the classic literatures. Cheonkeumbang (千金方) tried to suggest a reasonable classification of LBP in a relatively early age. In Dangyesimbeop (丹溪心法) the causes of LBP were divided into 6 factors; qi movement stagnation (氣鬱), dampness-heat (濕熱), kidney deficiency (腎虛), static blood (瘀血), sprain (挫閃) and phlegm accumulation (積痰). It had a lot of influence on the classic literatures published later. Donguibogam was also influenced by the Dangyesimbeop and the ten types of LBP in Donguibogam was similar to the information on the classification shown in Uihakipmun (醫學入門) and Uijongpildok (醫宗必讀). Conclusions We verified universality of the ten types of LBP; kidney deficiency, phlegm-retained fluid (痰飮), food accumulation (食積), sprain, static blood, wind (風), cold (寒), dampness (濕), dampness-heat and qi (氣).

  • In traditional Korean medicine, inspection of the tongue is an important method of making medical diagnoses and determining prognosis. We surveyed the fluorescence characteristics of the tongue coat in the ultraviolet light. The tongue coat comprises micro-organisms, blood metabolites, leukocytes from periodontal pockets, large amounts of desquamated epithelial cells released from the oral mucosa and different nutrients. In the ultraviolet light tissues of the oral cavity generally emit weak red or green fluorescence, which is not easily seen by the human eye, but is readily detected. This fluorescence has been proved to be due to the production of porphyrins by oral micro-organisms. While the composition of motile micro-organisms on the dorsum of the tongue is not constant, variations also occur persistingly in the fluorescence characteristics of the tongue coat. But because live bacteria contain a variety of intracellular biomolecules that have specific excitation and emission wavelength spectra characterizing their intrinsic fluorescence, the tongue coat emits fluorescence. the tongue itself, on the other hand, emits very weak or not fluorescence. In conclusion, we suggests that the uncoated tongue area be eliminated from the coated tongue area with the difference between the fluorescence characteristics of the tongue and that of the tongue coat.

  • Objectives The purpose of this study was to survey the current status of use of questionnaires for evaluating Yin Deficiency Syndrome and analyze the comparison with questionnaires. Methods We searched online medical databases to find domestic/international articles using questionnaires for evaluating intensity of Yin Deficiency Syndrome. Finally 18 articles were collected to be reviewed and they were classified according to their subjects and type of the Questionnaires. Results Out of 18 articles, 11 were based on the Yin-Deficiency Questionnaire (Yin-DQ) and the others used various questionnaires, except the Yin-DQ, for assessing Yin Deficiency Syndrome. In Korea the Yin-DQ was used widely but in foreign countries, for instance, China, Taiwan, a variety of questionnaires were used. Conclusion The Yin-DQ had a wider use in assessing Yin Deficiency Syndrome, but cut-off score for diagnostic criteria was not defined. Therefore, we decided that the YDS (Yin Deficiency Scale) with cut-off score was more suitable for screening patients with Yin Deficiency Syndrome. Moreover, we suggested that additional studies on using the YDS and developing more appropriate diagnostic tool should be conducted to improve diagnostic objectivity.
