정병천,박순홍,이주영,이신원,정성창,김정국,하승우,김보완 대한비만학회 2003 The Korean journal of obesity Vol.12 No.2

연구배경: 비만은 제2형 당뇨병의 중요한 병인이면서 죽상경화성 동맥질환의 위험인자인 인슐린 저항성, 지질대사 이상 및 고혈압의 원인으로도 인정되고 있다. 한편 비만에 의한 대사성 및 혈관 합병증은전신적 지방량의 증가보다 복강내 지방축적이 병인적 중요성을 가지고 있다고 한다 그러나 국내의 제2형 당뇨병 환자를 차상으로 비만과 이들 죽상경화증 위험인자와의 상관관계를 연구 조사한 성적은 많지않다. 이에 제2형 당뇨병 환자에서 전신적 비만과 복강내 지방 축적을 반영하는 각각의 신체계측지수들과 죽상경화증 위험인자와의 상관성을 검토함으로써 국내 제2형 당뇨병 환자의 비만도가 대사성 및 혈관성 합병증에 미치는 영향과 신체계측지수들의 임상적 가치를 평가하고자 하였다. 방법 : 제2형 당뇨병 환자 425명 (남자 196명, 여자 229명)을 차상으로 하였다 임상적 단백뇨가 있거나 인슐린 치료, 혈압강하제 또는 지질대사개선제를 복용하는 환자는 제외시켰다. 전신 비만은 체용적지수 그리고 피부두겹 두께로 산출한 체지방률을, 복강내 지방축적도는 허리둘레 및 요둔위비를 이용하였다. 죽상경화증의 위험인자로는 혈당 조절 정도를 나타내는 공복 혈당과 당화혈색소 농도, 인슐린 저항성을 나타내는 공복 인슐린 및 C-peptide 농도, 지질 대사 상태를 나타내는 총 콜레스테롤, 중성지방, 고밀도지단백 콜레스테롤 및 저밀도지단백 콜레스테롤 농도 그리고 수축기 및 이완기 혈압을 선택하였다. 전신 비만지수 및 복부 비만지수와 이들 위험인자와의 상관관계는 연령과 당뇨병 이환기간을 보정하고 편상관분석법을 사용하였다. 결과: 1 여성군에서 남성군에 비해 체용적지수(24.2 대 23.0kg/㎡, p<0.01) 및 체지방률(23.8 대13.5%, p<0.01)은 다소 높았으나 허리둘레 (87.0 대 85.8 cm)와 요둔위비 (0.96 대 0.96)는 차이가 없었다. 2. 인슐린 저항성을 반영하는 공복 인슐린 및 C-peptide 농도는 체용적지수. 체지방률, 허리둘레 및 요둔위비가 커질수록 증가하는 양의 상관관계를 보였다(상관차수 0.21∼0.42, 모두 p<0.05). 3. 혈청 지질중에는 고밀도지단백 콜레스테롤만이 남성 환자군에서 비만지수들과 약한 음의 상관성을 보이는 경향이었고, 총 콜레스테롤 및 중성지방농도는 상관성이 없었다. 4. 수축기 및 이완기 혈압은 남성군에서만 체용적지수. 체지방률, 허리둘레 및 요둔위비가 커질수록 상승하는 양의 상관관계를 보였다(상관차수 0.21∼0.33, 모두 p.0.05). 결론. 국내 제2형 당뇨병 환자들의 전신 비만도 및 복부 비만도가 서구인에 비해 심하지는 않으나 포도당 대사, 인슐린 저항성, 지질 대사 및 고혈압에 위해한 영향을 미칠 수 있는 수준에 이르고 있으며 이는 결국 죽상경화증의 위험인자로도 작용하게 될 것임을 시사한다고 하겠다. 그리고 신체계측을 통한전신 비만 및 복부 비만 지수 모두가 당뇨병 및 죽상경화증의 위험을 간접적으로 예견하는 유용한 척도가 될 수 있을 것이다. Background: Obesity is the powerful risk factor for type 2 diabetes and also associated with a significantly increased risk of insulin resistance, dyslipidemia, hypertension and atherosclerosis. Although obese individuals have these diseases, the relationship between obesity and these diseases was not certain until regional fat distribution was taken into account. Reports about the relationship between obesity and the risk factors of atherosclerosis in type 2 diabetics in Korea are very rare. To evaluate the relative importance of anthropometric indices on the development of atherosclerosis and obesity-related metabolic and vascular complications, the correlations of these indices with the risk factors for atherosclerosis were studied. Methods: Patients with type 2 diabetes mellitus (n=425, male 196, female 229) who not used antihy- pertensives or anti-lipidemic agents were investigated. Body mass index (BMI) and percentage of body fat (%BF) estimated by skinfold-thickness in assessing generalized adiposity, and waist circumference (Wc) and waist-to-hip ratio (WHR) in assessing visceral adiposity were taken as anthropometric indices. We included the indicators of glycemic control (fasting blood sugar and HbAlc), insulin resistance (fasting serum insulin and C-peptide concentrations), lipid abnormalities (serum total cholesterol, triglyceride, HDL-cholesterol, and LDL-cholesterol concentrations), and systolic and diastolic blood pressure as risk factors for the development of atherosclerosis. Partial correlations of the anthropometric indices with those risk factors were investigated with adjustment of age and duration of illness. Results: 1. BMI and %BF in female patients group were higher than those in male (24.2 vs 23.0 kg/㎡, 23.8 vs 13.5%, respectively, p<0.01 in all) although Wc and WHR were similar between both groups. In general, both body adiposity and abdominal obesity in them were much lower than in the Western. 2. Serum insulin and C-peptide levels were positively correlated with BMI, %BF, Wc and WHR (r=0.21~42, p<0.05 in all). 3. Serum total cholesterol, triglyceride and LDL- cholesterol were not correlated with any anthropometric indices. A weak negative correlation of serum HDL-cholesterol with these indices was found in male patients group. 4. Both systolic and diastolic blood pressures were positively correlated with all these indices only in male group (r=0.21~33, p<0.05 in all). Conclusion: These results suggested that the severity of both generalized and visceral adiposity in these patients with type 2 diabetes mellitus were only mild but adiposity with abdominal distribution of body fat in diabetes mellitus could be a significant risk factor of developing atherosclerosis. In clinical practice, these anthropometric indices indicating general adiposity and abdominal obesity may provide useful information for predicting disease risks, especially of diabetes and cardio- vascular disease indirectly.

손보성,송준영,정재봉,김병천,이상숙,류영욱,이규석 啓明大學校 醫科大學 1994 계명의대학술지 Vol.13 No.4

Papulonecrotic tuberculid is an eruption of necrotizing papules, particularly affecting the extremities and occurring in more or less symmetrical crops, and responding to antituberculosis therapy. Individual lesions heal with scarring. Histologically, vascular involvement is seen in early lesions. Late lesions are divided into two forms. In superficial forms, wedge shaped area of necrosis forms in epidermis and upper dermis. Epithelial and lymphoid cells gather around its periphery. In deep forms, with no epidermal change, granulomatous changes surrounded by well defined palisading histiocyte and lymphoid, epithelioid cells are seen. In mid-dermis and perivascular area, vessel shows vasculitis. In the first case, leukocytoclastic vasculitis and early granuloma formation were seen. In the second case, palisading granuloma formation was seen. In the third case, tuberculoid granuloma formation was seen. We report three cases of papulonecrotic tuberculid showing three different stages of histological finding, in individual cases.

Natural History of Chronic Urticaria in Korea

( Bo Young Chung ),( Ji-young Um ),( Seok Young Kang ),( Hye One Kim ),( Chun Wook Park ) 대한피부과학회 2020 Annals of Dermatology Vol.32 No.1

Background: Data on the natural history and prognostic variables of chronic urticaria (CU) are rare and information about spontaneous remission of CU is limited. Objective: This study evaluated the natural history of CU and identified predictors for remission. Methods: Total 329 Korean patients with CU, who had follow-ups more than 6 months after diagnosis during a 7-year period in the department of dermatology in three university hospitals were enrolled. Clinical data and laboratory findings obtained by medical records and telephone interviews were analyzed, retrospectively. Results: The proportion recovered in 1, 3, and 5 years after the onset of CU was 10.8%, 18.8%, and 32.9%, respectively. The mean duration of CU was 6.3 years. There were no significant differences in median recovery time depending on sex, age group, severity of CU, and type of CU. The presence of angioedema was significantly related to CU severity. There were no differences in prognosis with respect to the presence of dermographism or angioedema. Patients with atopic dermatitis (AD) had a significantly worse prognosis than patients without a history of AD; but not in patients with the history of allergic rhinitis or asthma. Patients with abnormal laboratory findings did not differ significantly in prognosis. Conclusion: CU remission rate significantly differ according to the presence of AD. This study provides information about the natural course of CU of Korean patients. (Ann Dermatol 32(1) 38∼ 46, 2020)

Effect of Different Cooking Methods on Histamine Levels in Selected Foods

( Bo Young Chung ),( Sook Young Park ),( Yun Sun Byun ),( Jee Hee Son ),( Yong Won Choi ),( Yong Se Cho ),( Hye One Kim ),( Chun Wook Park ) 대한피부과학회 2017 Annals of Dermatology Vol.29 No.6

Background: Histamine in food is known to cause food poisoning and allergic reactions. We usually ingest histamine in cooked food, but there are few studies about the influence of cooking method on the histamine level. Objective: The purpose of this study was to determine the influence of cooking methods on the concentration of histamine in foods. Methods: The foods chosen were those kinds consumed frequently and cooked by grilling, boiling, and frying. The histamine level of the food was measured using enzyme-linked immunosorbent assay. Results: Grilled seafood had higher histamine levels than raw or boiled seafood. For meat, grilling increased the histamine level, whereas boiling decreased it. For eggs, there was not much difference in histamine level according to cooking method. Fried vegetables had higher histamine levels than raw vegetables. And fermented foods didn’t show much difference in histamine level after being boiled. Conclusion: The histamine level in food has changed according to the cooking method used to prepare it. Frying and grilling increased histamine level in foods, whereas boiling had little influence or even decreased it. The boiling method might be helpful to control the effect of histamine in histamine-sensitive or susceptible patients, compared with frying and grilling. (Ann Dermatol 29(6) 706∼714, 2017)

Bo-Hee, Lee,Young-Chun Park,SOX-SU Lee,Byung-Joo Lee,Yeong-Guk Kim,Yeong-Seob An 한국유기농업학회 2011 韓國有機農業學會誌 Vol.19 No.S

For the development of Boxthorn organic cultivation techniques, we investigated effect of several organic compost as a foundation fertilizer and growing plant fertilizer. And we adopted partly opening rain shelter greenhouse to protect anthracnose. In organic compost applying test yield characteristics of ‘Mixed organic compost’ treatment was the best but in betaine content measurement of dried fruit, ‘Mixed organic compost and nitrogen guano ’ treatment was the best and it’s chlorophyll and 100 fruit weight were also betfer than the other treatments.

Increased 1-Deoxysphingolipids and Skin Barrier Dysfunction in the Skin of X-ray or Ultraviolet B Irradiation and Atopic Dermatitis Lesion Could Be Prevented by Moisturizer with Physiological Lipid Mixture

( Bo Young Chung ),( Hye One Kim ),( Seok Young Kang ),( Min Je Jung ),( Sung Woo Kim ),( Kyung Sook Yoo ),( Kyong Oh Shin ),( Se Kyoo Jeong ),( Chun Wook Park ) 대한피부과학회 2020 Annals of Dermatology Vol.32 No.4

Background: Skin diseases characterized by epithelial barrier dysfunction show altered sphingolipid metabolism, which results in changes in the stratum corneum intercellular lipid components and structure. Under pathological conditions, 1-deoxysphingolipids form as atypical sphingolipids from de novo sphingolipid biosynthesis. Objective: This study investigated the potential role of 1-deoxysphingolipids in skin barrier dysfunction secondary to X-ray and ultraviolet B (UVB) irradiation in vitro and in vivo. It was also evaluated changes in the expression of 1-deoxysphingolipids in lesional human skin of atopic dermatitis. Methods: In this study, the changes in these 1-deoxysphingolipids levels of skin and serum samples were investigated in skin barrier dysfunction associated with X-ray and UVB irradiation in vitro and in vivo. Results: Increased 1-deoxysphingolipids were observed in cultured normal human epidermal keratinocytes after X-ray irradiation. X-ray or UVB irradiation increased the production of 1-deoxysphingosine in a reconstituted 3-dimensional (3D) skin model. Interestingly, treatment with a physiological lipid mixture (multi-lamellar emulsion contained pseudoceramide), which can strengthen the epidermal permeability barrier function, resulted in decreased 1-deoxysphingosine formation in a reconstituted 3D skin model. Further investigation using a hairless mouse model showed similar preventive effects of physiological lipid mixture against 1-deoxysphingosine formation after X-ray irradiation. An increased level of 1-dexoysphingosine in the stratum corneum was also observed in lesional skin of atopic dermatitis. Conclusion: 1-deoxysphingosine might be a novel biomarker of skin barrier dysfunction and a physiological lipid mixture treatment could prevent 1-deoxysphingosine production and consequent skin barrier dysfunction.

Reduction of Deviation Angle During Occlusion Therapy: In Partially Accommodative Esotropia with Moderate Amblyopia

( Bo Young Chun ),( Soon Jae Kwon ),( Sun Hwa Chae ),( Jung Yoon Kwon ) 대한안과학회 2007 Korean Journal of Ophthalmology Vol.21 No.3

Purpose: To evaluate changes in ocular alignment in partially accommodative esotropic children age ranged from 3 to 8 years during occlusion therapy for amblyopia. Methods: Angle measurements of twenty-two partially accommodative esotropic patients with moderate amblyopia were evaluated before and at 2 years after occlusion therapy. Results: Mean deviation angle with glasses at the start of occlusion treatment was 19.45±5.97 PD and decreased to 12.14±12.96 PD at 2 years after occlusion therapy (p<0.01). After occlusion therapy, 9 (41%) cases were indications of surgery for residual deviation but if we had planned surgery before occlusion treatment, 18 (82%) of patients would have had surgery. There was a statistical relationship between increase of visual acuity ratio and decrease of deviation angle (r=-0.479, p=0.024). Conclusions: There was a significant reduction of deviation angle of partially accommodative esotropic patients at 2 years after occlusion therapy. Our results suggest that occlusion therapy has an influence on ocular alignment in partially accommodative esotropic patients with amblyopia. Korean Journal of Ophthalmology 21(3):159-162, 2007
