Objectives Mibyeong is an ideological concept that means the state between the healthy and diseased conditions. The purpose of this study was to suggest a research direction to establish the diagnostic criteria for the Mibyeong by reviewing the research results for the Mibyeong. Methods Academic databases (OASIS for Korean database, Embase for English database, and CNKI for Chinese database) were used to search related literatures, and articles describing the concept or diagnostic criteria of the disease were selected. Results The concept of Mibyeong consisted of three different conditions: (1) subjective symptoms without a specific disease, (2) abnormal examination findings without a specific disease, and (3) a state in between health and disease. No matter which of the three conditions is applied, the spectrum of condition was very wide and diverse. Conclusions It is impossible to apply appropriate and monolithic diagnostic criteria to all types of Mibyeong. Therefore, we suggests that the Mibyeong be classified into several subtypes and the diagnostic criteria suitable for each type be established.

Purpose: A new form of porous polyethylene, characterized by higher porosity and pore interconnectivity, was developed for use as a tissue-integrated implant. This study evaluated the effectiveness of porous polyethylene blocks used as an onlay bone graft in rabbit mandible in terms of tissue reaction, bone ingrowth, fibrovascularization, and graft-bone interfacial integrity. Methods: Twelve New Zealand white rabbits were randomized into 3 treatment groups according to the study period (4, 12, or 24 weeks). Cylindrical specimens measuring 5 mm in diameter and 4.5 mm in thickness were placed directly on the body of the mandible without bone bed decortication, fixed in place with a titanium screw, and covered with a collagen membrane. Histologic and histomorphometric analyses were done using hematoxylin and eosin-stained bone slices. Interfacial shear strength was tested to quantify graft-bone interfacial integrity. Results: The porous polyethylene graft was observed to integrate with the mandibular bone and exhibited tissue-bridge connections. At all postoperative time points, it was noted that the host tissues had grown deep into the pores of the porous polyethylene in the direction from the interface to the center of the graft. Both fibrovascular tissue and bone were found within the pores, but most bone ingrowth was observed at the graft-mandibular bone interface. Bone ingrowth depth and interfacial shear strength were in the range of 2.76-3.89 mm and 1.11-1.43 MPa, respectively. No significant differences among post-implantation time points were found for tissue ingrowth percentage and interfacial shear strength (P>0.05). Conclusions: Within the limits of the study, the present study revealed that the new porous polyethylene did not provoke any adverse systemic reactions. The material promoted fibrovascularization and displayed osteoconductive and osteogenic properties within and outside the contact interface. Stable interfacial integration between the graft and bone also took place.

Objectives: Medical students suffer from mental health and academic problems due to academic stress. We investigated academic stress and exhaustion along with psychological issues caused by medical education during the years in the School of Korean Medicine. Methods: Two hundred fifty-one university students from the School of Korean Medicine, Pusan National University, were asked to complete the Medical Stress Scale (MSS), Maslach Burnout Inventory-Student Survey (MBI-SS), Positive Affect and Negative Affect Schedule (PANAS), and State-Trait Anxiety Inventory (STAI) three times during each semester for two years from 2013 onwards. We analyzed the influence of school term and vacation on educational stress and negative affect with the T-test. The Pearson's correlation analysis and regression analysis were used to predict changes during the first semester or first years of study in the School of Korean Medicine. Results: Academic stress and burnout increased steadily until the first semester of third grade, which was measured with MSS and MBI-SS. The anxiety level was highest when the students started the first grade and it decreased significantly after the first semester. Negative affect repeatedly increased significantly after each school term; however, it reduced after each vacation. In the first grade, 19.5% of the last measure of MSS can be explained with the first measure of MSS. Discussion: This study extensively reviewed the trends and characteristics of four years of academic stress and its related psychological influence, and discussed its importance for developing a more efficient academic curriculum for traditional Korean Medicine.

Backgrounds : In recent years there has teen renewed interest in the importance of 8-constitution medicine as evidenced by growth of research in this field. Although diagnosis by 8-constitution depends on pulse types, it still is subjective and thus could be insignificant. Therefore, diagnosis based on objective characteristics is essential. Objectives : The purpose of this study was to find objective characteristics of the 4-constitution groups {木(Mok; hepatonia, cholecystonia), {土(To; pancreotonia, gastrotonia), {金(Gum; pulmotonia, colonotonia), {水(Soo; renotonia, vesicotonia)} in 8-constitution for further diagnosis and therapy. Also, some significant clinical tendencies of 4-constitution groups were studied. Methods : From Nov. 2001 to Apr. 2004, data were collected through a questionnaire given to 720 patients who were classified into one of 8 constitutions according to their pulse types and their responses to constitution-based acupuncture therapy. The questionnaire was composed of 80 items which were about personality, physical shape, habit, physiological and pathological symptoms, response to drugs, favorites and responses to various foods. The data were statistically analyzed by cross-tabulation and one-way analysis of variance, and SPSS V10.0.7PC was used. Results : The results are summarized as follows: 1) Among participants, proportions of hepatotonia, pancreotonia, and cholecystotonia were higher than those of vesicotonia, pulmotonia, colonotonia, renotonia, grstrotonia. 2) 52 items of 80 variances showed significant differences by gender, 3) 13 items were highly correlated with 4-constitution groups in males, and 26 items in fremales. 4) 22 items showed significant group differences among 4-constitution groups in males, and 41 items in females. Also, for each item 4-constitution groups were sorted according to their means, so that the constitutional tendencies were objectively figured out by personality, shape, habit, physiological and pathological symptoms, response to drugs, favorites and responses to foods. Conclusions : Most clinical characteristics of 4-constitution groups found in this study coincided with those from the previous ones in this fold. Thus, classifying patients into one of the 4-constitution groups based on significant objective characteristics is of great benefit to diagnosis and therapy. further study should be followed to improve proper therapy for each constitution.

Objectives The Sasang Personality Questionnaire (SPQ) measures the Yin-Yang temperament of Sasang typology with proven structural and clinical validity in adults, however it was not examined with teenagers. The purpose of this study was to validate the biopsychological structure of SPQ in middle school students.Methods 681 Korean high school students (356 boys and 325 girls) completed SPQ, Junior version of Temperament and Character Inventory (JTCI), and height and weight measures. The correlation between SPQ and JTCI subscales were examined, and the differences of SPQ and JTCI subscales, Body Mass Index (BMI) and Pondera Index (PI) among high (30%), middle (40%), and low (30%) SPQ total score groups were investigated with Analysis of Variance (ANOVA). The profile analysis was also performed to compare JTCI subscale profiles of three SPQ total score groups.Results The SPQ score was significantly (p<0.001) correlated positively with JTCI Novelty-Seeking and negatively with JTCI Harm-Avoidance. The JTCI Novelty-Seeking score of high SPQ group was significantly (p<0.001) higher than that of low SPQ group, and the JTCI Harm-Avoidance score of low SPQ group was significantly higher than that of high SPQ group. The JTCI subscale profiles for three SPQ groups were significantly different for boys and girls. Significant correlations or differences for the PI and BMI among SPQ groups were not found.Conclusions This study presented that the biopsychological structure of SPQ is robust as shown in adults. The SPQ would be a useful clinical measures of Sasang typology in pediatric patients.

Brain-type natriuretic peptide (BNP)은 뇌나트륨이뇨펩티드로, 좌심실의 심근세포에서 분비되는 호르몬으로, 심장과 신장에 작용하여 혈관 확장과 나트륨 이뇨 작용 등을 하는 것으로 알려져 있으나, 최근에는 다양한 조직에서 대사 작용을 조절하는 것으로 보고된다. 본 연구에서는 간 조직에서 BNP의 영향을 알기 위해 BNP가 고지방식이에 의해 유도되는 인슐린 저항성을 개선하는지를 조사하였다. BNP을 주입한 쥐와 control로서 saline을 주입한 쥐들 간에는 몸무게, 체지방양(fat mass), 제지방량(lean body mass)의 변화는 없었다. 고인슐린혈증 정상혈당 글루코스 클램프(Hyperinsulinemic Euglycemic Glucose Clam) 동안, BNP를 주입한 고지방 식이 쥐들은 saline을 주입한 고지방식이 쥐에 비해 혈당(blood glucose)은 감소하였으며, 포도당 주입 속도(glucose infusion rate)는 증가하였다. 또한 BNP은 포도당 신생 및 중성지방 합성 관련 유전자들의 발현을 감소시켜, 간에서 포도당 생성과 중성지방의 양을 감소시켰다. BNP는 saline을 주입한 쥐에 비해 간 조직에서 Akt와 AMP-activated protein kinase (AMPK)의 인산화를 증가시켰는데, 이는 BNP을 처리한 AML12 간세포에서도 BNP는Akt와 AMPK 인산화를 증가시켰다. 이상의 결과는 BNP가 간에서 인슐린 저항성을 개선하여 포도당 생성과 중성 지방 생성을 억제함을 알 수 있었다.
