  • Objectives Iridology is a field of study that diagnoses various systemic diseases through analysis of colors, structural characteristics and changes in iris. The purpose of this study was to review previously published study results of the iridology. Methods The studies were searched with the keyword "iridology" through search engines such as SCOPUS, Pub med, RISS, and NDSL. Total of 36 iridology-related studies published from 1980 to 2012 were analyzed. Results Most diagnoses of systemic disease through iris markings were insignificant. The studies on relevance of gene polymorphism and iris constitution were highly significant. The studies on relevance of Sasang constitution and iris constitution varied in results depending on diagnosis methods. The studies on relevance of iris constitution and diseases had significant results. The structural characteristics of iris were related to certain personality. Conclusions The studies on utility of iris diagnosis and diagnostic markings were negative, but the relevance of constitution, heredity, and iris diagnosis was positive. A persistent in-depth study on relevance of iris and constitution is needed in the future.

  • Objectives The purpose of this study was to survey the status of clinical use of a computerized tongue diagnosis system (CTDS) Methods We searched domestic/international articles using the CTDS from online medical databases including OASIS, NDSL and pubmed. We selected articles on clinical application or reliability of CTDS but excluded articles on mechanical design or software programming for developing a new CTDS. Finally we found 15 articles and classified the articles according to the study purpose. Results Out of the 15 articles, 8 were focused on the clinical application including halitosis, cold/heat syndrome, lung cancer, xerostomia etc. Other 5 articles were aimed at evaluating and improving reliability of CTDS. The other 2 articles were studied for development of differential diagnostic criteria on tongue coating thickness. Conclusion We found out that until now the researches on clinical application of CTDS mainly had been performed for producing a variety of CTDSs. Considering the importance of the tongue color in the traditional Korean medicine, we suggest that at first standard operating procedure for CTDS be developed and researches to develop differential diagnostic criteria on tongue body/coating color be performed and then explore its applications.

  • Objectives: There is currently increased interest in the identification of natural antioxidant compounds derived from various plants. Peony Root (PR) is used worldwide for the treatment of many types of cardiovascular disease including atherosclerosis and hypertension. It has been used in Korean traditional medicine for the treatment of glycosuria, hypertension and cancer. However, to date, no studies concerning the antioxidant properties of PR have been conducted. Therefore, this study was conducted to evaluate the in vitro scavenging activity, inhibitory effect of LDL oxidation of pro-oxidant reactive species and anti-thrombosis effect in response to treatment with PR using various screening methods including biological and non-biological oxidants. Methods: In this study, the antioxidant activity of extract from PR was studied with in vitro methods by measuring the antioxidant activity by TEAC, measuring the scavenging effects on reactive oxygen species (ROS) [superoxide anion, hydroxyl radical] and on reactive nitrogen species (RNS) [nitric oxide and peroxynitrite] as well as measuring the inhibitory effect on $Cu^{2+}$-induced human LDL oxidation and the inhibitory effect on collagen-induced platelet aggregation. Results: The PR extracts were found to have a potent scavenging activity of oxidative stress [DPPH, superoxide anion, hydroxyl radical, nitric oxide and peroxynitrite, etc.] as well as an inhibitory effect on LDL oxidation and on platelet aggregation. Conclusions: The PR extracts have anti-oxidative and anti-atherosclerotic effects in vitro system, which can be used for developing pharmaceutical drugs against oxidative stress and atherosclerosis.

  • The CCAAT/enhancer-binding protein-alpha (CEBPA) is a transcriptional factor that plays a crucial role in the control of proliferation and differentiation of myeloid precursors. This gene was recognized as the target of genetic alterations and were associated with clinical complexity among AML. We here analyze the frequency and types of CEBPA mutations and polymorphisms in a de novo AML patients from South India and tried to find out associations of these variations with different clinical parameters and the prognostic significance in AML. Study was carried out in 248 de novo AML patients, cytogenetic analysis was performed from the bone marrow samples and was karyotyped. PCR-SSCP analysis and sequencing was performed for the detection of CEBPA gene variations. All the statistical analysis was performed using SPSS 17 (statistical package for social sciences) software. Pearson Chi-square test, Mann-Whitney U test, Kaplan-Meier survival analysis and log rank tests were performed. CEBPA mutations were detected in 18% and CEBPA polymorphisms were detected in 18.9% of AML cases studied. Most of the mutations occured at the C terminal region. Polymorphisms were detected in both N and C terminal region. with most common being, c.584_589dup ACCCGC and c.690G>T. A significant association was not observed for the mutation and polymorphism with respect to clinical and laboratory parameters. Survival advantage was observed for the mutated cases compared to non mutated cases, especially for the normal karyotype groups. Polymorphisms has no effect on the survival pattern of AML patients. CEBPA mutation and polymorphisms were observed with similar frequency and was identified in all the FAB subtypes as well as in cytogenetic risk groups in our study population, but CEBPA mutations alone confer a prognostic value for NK AML patients.

  • Objectives As a method of body temperature distribution diagnosis, palpation of infants' forehead had been widely introduced in ancient East Asian medical classics. However, few attention have been paid to this diagnostic method - so called 'emaizhenduan (額脈診斷)'. So we studied the history of emaizhenduan and it's implication in modern clinical field. Materials and methods: To search the medical classic that contains any contents of emaizhenduan, we mainly used the electronic texts of Zhonghuayidian (中華醫典). To search modern study article on emaizhenduan, we used China National Knowledge Infrastructure (www.cnki.net), National Digital Science Library (ndsl.kr) etc. Results 20 kinds of East Asian medical classics were found to contain contents on emaizhenduan. The oldest one was Huoyoukouyi (活幼口議) which was written in Yuan dynasty of China. Only one modern TCM book was found to have comments on emaizhenduan, while some textbooks of pediatrics in Korean Medicine was found to have relatively sound introduction on emaizhenduan. Conclusion It is shown in ancient East Asian medical classics that infants' forehead temperature palpation was introduced as early as late 13th century in China, and have continuously been referred in many East Asian medical classics before modern era.
