Purpose: Neoadjuvant chemotherapy has been shown to improve survival in locally advanced gastric cancer, but it is associated with significant toxicity. Sarcopenia and sarcopenic obesity have been studied in several types of cancers and have been reported to be associated with higher chemotherapy toxicity and morbi-mortality. The aim of this study was to assess the prevalence of sarcopenia/sarcopenic obesity in patients with gastric cancer, as well as its association with chemotherapy toxicity and long-term outcomes. Materials and Methods: A retrospective analysis was performed using an academic cancer center patient cohort diagnosed with locally advanced gastric cancer between January 2012 and December 2014 and treated with neoadjuvant chemotherapy. We analyzed body composition (skeletal muscle and visceral fat index) in axial computed tomography images. Results: A total of 48 patients met the inclusion criteria. The mean age was $68{\pm}10years$, and 33 patients (69%) were men. Dose-limiting toxicity was observed in 22 patients (46%), and treatment was terminated early owing to toxicity in 17 patients (35%). Median follow-up was 17 months. Sarcopenia and sarcopenic obesity were found at diagnosis in 23% and 10% of patients, respectively. We observed an association between termination of chemotherapy and both sarcopenia (P=0.069) and sarcopenic obesity (P=0.004). On multivariate analysis, the odds of treatment termination were higher in patients with sarcopenia (odds ratio=4.23; P=0.050). Patients with sarcopenic obesity showed lower overall survival (median survival of 6 months [95% confidence interval {CI}=3.9-8.5] vs. 25 months [95% CI=20.2-38.2]; log-rank test P=0.000). Conclusions: Sarcopenia and sarcopenic obesity were associated with early termination of neoadjuvant chemotherapy in patients with gastric cancer; additionally, sarcopenic obesity was associated with poor survival.

Background: Specific immunoglobulin E (IgE) sensitization to staphylococcal enterotoxin (SE) has been recently considered to be related to allergic disease, including asthma. Despite studies on specific IgE (sIgE) to SE and its relationship to asthma diagnosis and severity, the association of sIgE to SE with airway hyperresponsiveness (AHR) remains unclear. Methods: We enrolled 81 asthma patients admitted to the Severance Hospital in Korea from March 1, 2013, to February 28, 2015 and retrospectively reviewed the electronic medical records of the enrolled subjects. The serum levels of sIgE to SE (A/B) of all subjects was measured using the ImmunoCAP 250 (Phadia) system with SE-sIgE positive defined as >0.10 kU/mL. Results: The SE-sIgE level was not significantly correlated with asthma severity (forced expiratory volume in 1 second [$FEV_1$], $FEV_1$/forced vital capacity, sputum eosinophils, and serum eosinophils), whereas the SE-sIgE level in patients with positive AHR ($mean{\pm}standard$ error of the mean, $0.606{\pm}0.273kU/mL$) was significantly higher than that in patients with negative AHR ($0.062{\pm}0.015kU/mL$, p=0.034). In regression analysis, SE sensitization (sIgE to SE ${\geq}0.010kU/mL$) was a significant risk factor for AHR, after adjustment for age, sex, $FEV_1$, and sputum eosinophils (odds ratio, 7.090; 95% confidence interval, 1.180-42.600; p=0.032). Prevalence of SE sensitization was higher in patients with allergic rhinitis and non-atopic asthma patients, as compared to patients without allergic rhinitis and atopic asthma patients, respectively, but without statistical significance. Conclusion: SE sensitization is significantly associated with AHR.

Background: Pulmonary tuberculosis remains a health concern in Korea despite major progress in the development of new strategies for diagnosing and treating tuberculosis. In particular, the diagnosis of newly developed pulmonary tuberculosis is on the rise in elderly persons. The aim of this study was to investigate the clinical, radiographic characteristics, and treatment outcomes of pulmonary tuberculosis in the elderly. Methods: The medical records of 113 young (<65 years old) and 112 elderly (${\geq}65$ years old) pulmonary tuberculosis patients diagnosed at Chungnam National University hospital between January 2007 and December 2008 were reviewed. Results: There was no difference in the prevalence of typical symptoms between the younger and the elderly group. Dypsnea was the only symptom that occurred more frequently in the elderly group (16.8% vs 5.5%, p=0.008). On radiological study, pneumonic infiltration type was more common in the elderly group (28.6% vs 16.8%, p=0.035). Sputum Acid fast bacilli smear positivity rate was similar between the 2 groups. Elderly patients with anti-tuberculosis medication had more frequent adverse drug reactions; however, there was no significant difference between the 2 groups in the number of patients required to stop medication due to an adverse drug reaction. There were more patients lost to follow-up in the elderly group (22/112, 19.6% vs 11/113, 9.7%, p=0.036). Conclusion: The majority of elderly patients did not complete the treatment, resulting in a poorer outcome. Therefore, we need to make an effort to support the continued screening of elderly patients by making this economically feasible.

Fascioliasis in cattle is one of the most common and very serious trematode diseases in Korea. In the present study, the enzyme linked immunosorbent assay (ELISA) was applied in the diagnosis of fascioliasis using antigen of Fasciela hepatica, perokidase of conjugate anti-cattle Is G and orthophenylenediamine as a substrate by micro-method technique of Volley et at. (1976b) and MacLaren (1978) with a slight modification. Results obtained from the present study are as follows. 1. In assay for optimal dilution of stock antigen, the antigen (protein contents; 0. Bmgymz) was diluted from 1150 to 1/600 with carbonate buffer (pH 9.6), and then absorbance values were measured with 1/100 diluted sera. The regression equations between the OD values of ELISA and dilution of antigen were log Y: -0.181-0.00127X in infected sera, and log Y: -0.578-0. 000879X in normal sera. The significantly higher (p<0.05) OD value was observed in the former. 2. In assay for optimal dilution of sera, the sera were diluted from 1125 to 1/400 with in PBSJ Tween 20 (pH 7.4), and absorbance values were measured with 1/200 diluted antigen. The regression equation between the OD values of ELISA and dilution of sera were log Y: -0.1540-0.0007238X in infected sera and log Y: -0.4834-0.00116X in normal sera. The former was higher than the latter (p<0.05). 3. In the 27 cases of negative intradermal test, OD values of the ELISA are $0.447{\pm}0.144$, the 95% confidence interval (Mean+2 H SD) of the values was 0.735, and there was no case over the values. Therefore, the sensitivity of the antigen to diagnose fascioliasis was 100% in the negative case. The OD value 0.7 which is designed as a criterion (detection level of positive one) is useful for the performance of the ELISA in fascioliasis. 4. According to the OD value of criterion in the regression equations, the optimal dilutions of stock antigen and serum were 1/250 and 1/100, respectively. 5. In the 58 cases of fascioliasis from which the adult could be found in the bile ducts, the OD value was $0.846{\pm}0.224$. The 75% (44 cattle) among them had higher value with compared to the criterion, and the 60% (20 cattle) of the cases of proliferative cholangitis of 33 cattle which had been infected previousely with Fasciola sp. is higher than the criterion. 6. Prevalence of fascioliasis was 43.4% in the application of the ELISA to 272 cattle which were reared in Jeonbug district.

소아청소년기의 이상지질혈증 유병율이 증가함에 따라 이에 대한 조기발견과 관리에 대한 중요성이 커지고 있다. 본 연구는 소아청소년의 성별과 연령에 따른 공복 혈청 지질 농도의 분포를 살펴보고, 참고 범위 설정을 위한 백분위수 값을 검토하여 이상지질혈증 진단기준과 비교해 봄으로써 참고범위의 타당성을 검증하고자 하였다. 2013년부터 2016년까지 총 4년에 걸친 국민건강영양조사 자료에서 10세 이상 20세 미만 연령의 소아청소년 총 2,711명(남자 1,436명, 여자 1,275명)의 데이터를 대상으로 하였다. 총콜레스테롤, LDL 콜레스테롤, HDL 콜레스테롤, non-HDL 콜레스테롤, 중성지방의 평균 공복 혈중 농도는 모두 남아보다 여아에서 더 높았다. 총 콜레스테롤 농도의 95백분위수에 해당하는 값은 남아의 경우 200 mg/dL로 95백분위수와 일치하는 수준이었고, 여아의 경우 208 mg/dL로 나타나 90~95백분위수 사이에 해당하였다. LDL 콜레스테롤, non-HDL 콜레스테롤, 중성지방의 95백분위수는 남아의 경우 각각 123, 148, 147 mg/dL였으며, 여아의 경우 각각 131, 149, 139 mg/dL였다. 대부분의 지표는 90~95백분위수 범위 내의 적절한 수준으로 나타났다. 반면에 LDL 콜레스테롤 130 mg/dL 기준은 남아에서, 중성지방의 기준은 여아에서 다소 높은 수준이라 판단되었다. 향후 연구대상자 및 자료를 보완하여 우리 실정에 좀 더 적합한 기준 정립이 필요하다.

간 섬유화는 임상에서 흔히 접하는 질환으로, 간세포 염증 및 괴사가 수년간 지속 및 반복되는 질환으로 간경변이 진행된다. 따라서, 만성 간질환 환자에서 간경변 및 간세포암으로의 진행을 막음으로써 간경변의 합병증 및 간세포암에 의한 사망률 및 유병률을 감소시키는 것이 주요한 임상 과제라 할 수 있다. 이에 본 연구에서는 미만성 간질환 환자에게서 초음파 영상, 혈액검사, 간탄력도와의 상관관계를 수치화 하고자 하였다. 본 연구에서는 P사의 초음파 진단기 (IU-22)로 영상을 획득한 환자와 Fibrosccan을 시행 받은 141명을 대상으로 시행하였고, 혈액 검사는 초음파 영상과 간섬유 스캔을 시행한 시점의 검사 결과로 기초자료를 획득하였다. 각 자료에 대한 통계 분석은 집단 간 차이 검증을 위해 일원분산분석(One-way, ANOVA)을 시행하여 검증하였다. 탄성 초음파의 수치는 정상, 만성간질환, 간경변 순으로 증가하였다. 판독 결과에 따라 ALT, Albumin은 대상군 간 통계학적 차이를 보이지 않았으며, 나이, AST, ALP, Bilirubin, PLT, PT, kPa에서 초음파 판독 결과에 따라서 차이가 있고, 통계적으로 유의(p<0.05)하였다. 그리고 다른 연구에서 만성 간질환 탄성 초음파 수치값이 12.5kPa 이상이라고만 제시하였으나, 본 연구에서는 질환별 평균 kPa임계값을 제시하여, 정량적으로 진단이 가능하게 수치화를 하였다. 또한, 진단결과의 상관관계를 제시하여 질환별 만성 간질환 환자의 진단에 일차적인 도구로 사용될 수 있으리라 사료된다.

1. Ounyukki(五運六氣) theory was first developed from observation of astronomical phenomena. Natural phenomena were explained and incorporated into the concepts of Yukki(六氣), and Ohaeng(五行, the concept that all matter in the world are comprised of five fundamental elements), during Chon-guk(戰國) and Han(漢) periods. In that period. Kanji(干支, the method to present time with ten and twelve different kinds of symbol's combinations) was used to record Ounyukki(五運六氣). Theoretical study of Un-gi(運氣, the abbreviation of Ounyukki) was almost completed in Un-gichilpyon(運氣七篇) of Naekyong(內經). Un-gi(運氣) theory was further studied and considered to be very important socially, as well as medically, in Tang(唐), Song(宋), Kum(金), and Won(元) periods. Hagan(河間) published various studies based on Un-gi(運氣) theory in Kum won(金元) periods. 2. Hagan(河間) realized the limitation of a remedy method, of Sanghan(傷寒) theory. Therefore, he made an assumption that the prevalence of diseases in his period are closely related to Hwayol(火熱, a fire and a super-heat; two things out of Yukki(六氣)). His new theory was a result of the study on Kyongjon(經典, bibles of the oriental medicine) and the phenomena of nature. 3. Hagan(河間) used a combination of two basic theories of Pimuripsang(比物立象) and Hanhaesungjeron(亢害承制論) to make understood Hwayol(火熱) theory, Pimuripsang(比物立象) theory explains a method to appreciate the essence of things by comparing Sang(象, an expression of how something appears on the outside) and then making another Sang(象) from the comparison. Hanhaesungjeron(亢害承制論) is a theory to emphasize the importance of a balance of Yukki(六氣). It is that, if one of the elements is exceeded, other thing in the other five elements dominate the exceeded thing to control it for the balance between Yukki(六氣). In addition, he articulated P'yobon(標本. inside and outside of a thing) theory to differentiate the disease symptoms. These theories will help to distinguish real and fake symptoms of diseases, on which Hagan(河間) emphasized its importance. 4. Hagan(河間) published a new theory to explain Ounyukki(五運六氣) theory based on the observation of the nature and the experience from medical practice. And he added Chobyonggi(燥病機, course and rule causing disease in dry conditions) to Pyonggishipkujo(病機十九條, nineteen course and rule causing disease), it strengthened Pyonggi(病機, course and rule causing disease) theories. Moreover. he utilized Un-gi (運氣) theory in a real life situation by applying Un-giron(運氣論) to diagnosis like Maekchin(脈診, a method to diagnose by taking the pulse) and to prescription. 5. Modern society is an era in which it is hard to appreciate the principles of the changes due to the various unusual weather. Therefore, it is necessary to make a new paradigm using Un-gi(運氣) theory, like Hagan(河間) did in Kumwon(金元) period. 6. Unusual weather changes and the geriatric diseases such as cancer and diabetes, may have Sang(象) of Hwayol(火熱) theory at the other side. These diseases have been and will create more serious problems in modern society. As a method to solve these problems. it seems to be very important to understand and apply Hagan's(河間) Hawyol(火熱) theory to modern society.
