The purpose of this study was to determine the health behaviors and nutritional status related to dyslipidemia in Korean middle-aged adults (between 50 and 64 years old) from the Korean National Health and Nutrition Examinations Survey data (2007~2010). A total of 4,721 subjects were analyzed in this study. The subjects were divided into three groups (normal, borderline, and dyslipidemia) according to serum lipid levels. Parameters included in this study were drinking and smoking, anthropometric parameters, blood and nutritional parameters. The latter parameter included food/nutrients intake. All data was adjusted by sex, region, education level, and age. General linear model and logistic regression model were used for statistical analysis. The dyslipidemia group was comprised of more men than women. By contrast, the borderline group was comprised of more women than men (p<0.001). No significant differences were observed for other general characteristics. There were more smokers and drinkers(drinking per time) in the dyslipidemia group (p<0.05). Anthropometric data showed significant difference, ie, height (p<0.05), weight, body mass index, waist circumference, percent body fat, and blood pressure were higher in the dyslipidemia group (p<0.001). Only blood urea nitrogen showed no significant difference among groups. The HbA1c (p<0.01), fasting blood glucose, GOT, GPT, creatinine levels were higher in the dyslipidemia group (p<0.001). So it is required for the management of obesity in dyslipidemia group. The dyslipidemia group ate less sea food (p<0.05). The nutrients intake of energy and protein, thiamin, riboflavin, niacin, calcium, phosphorus were lower in the dyslipidemia group (p<0.05). Therefore, to lower dyslipidemia prevalence rates, it is necessary to increase the intake of foods containing ${\omega}-3$ fatty acids. We also suggest a meal management program and nutritional education to recognize the risk of dyslipidemia, especially for people such as the individual in the borderline and dyslipidemia study groups.

Purpose : Adenoviruses(Ad) have been shown to play an important role in the etiology of severely acute respiratory diseases, particulary in infants and young children, and the occurrence of fatal outcome and chronic pulmonary sequelae in association with adenoviral infection has been a cause of great interest and concern. This report presents the resul of a retrospective analysis on 30 cases of lower respiratory infection from which adenovirus was isolated. Patients & Methods : The 30 patients in this study represent all detected cases of adenovial infection out of 240 children who were admitted to Sang Sung Medical Center between February to June 1996 showing signs and symptoms of lower respiratory tract infection. The diagnosis of adenovirus infection was based on microscopic visualization of typical cytopathic effect in HEp-2 tissue culture and used monoclonal Ab with nasopharyngeal aspiration. Results : The male/female ratio was 2:1 and the majority of age range was below 36months. Clinical diagnoses in all 30 patients were pneumonia(n=21), bronchitis and Bronchiolitis(n=5) and ARDS(n=4). We recieved the most of patients in the month of May. The chief complaints were fever(93.3%) and cough(80%) and extrapulmonary symptoms were diarrhea(n=5), seizure(n=4), abdominal pain(n=1). The mean duration of fever was $11.95{\pm}6.54$days. Physical examination on admission were crackles(73.3%), coarse breathing sounds(60%), hepatosplenomegaly(33.3%), decreased brething sounds(30%). In WBC counts, 8cases were below $4000/mm^3$ and 14 cases were above $10,000/mm^3$. In platelets counts, 4cases were below $150,000/mm^3$ and 10 cases were above $450,000/mm^3$. 21 cases were above 1 in CRP. GOT and GPT were abnormal in some cases. Chest X-ray revealed diffuse pulmonary infiltration(n=15), pleural effusion(n=6), consolidation(n=4) and hyperaeration(n=3). Seven patients were treated at the peditric intensive care unit with respiratory support and high dose of gammaglobulin. However, one patients died even through he was treated with NO ventilation and high frequency ventilation. Conclusion : Those with adenoviral pneumonia and respiratory infection having long fever duration and symptoms like bacterial pneumonia must be carefully differentiated in order to provide proper treatement and preventive measures due to possible fatal outcome.

The X-linked inhibitor of apoptosis (XIAP) is a member of a novel family of inhibitors of apoptosis and has several BIR domains (BIR1, BIR2, and BIR3) and a carboxy-terminal RING zinc-finger. Since suppressionof apoptosis is fundamentally important for carcinogenesis and tumor growth, we investigated the expression and function of XIAP in DEN-induced carcinogenesis using rat model. Wistar rats were injected intraperitoneally with DEN at a dose of 50 mg/kg in twice a week for 12 weeks (Group II) and 16 weeks (Group III) followed by the recovery periods, respectively. The evaluation of DEN-induced carcinogenesis carried out the blood, RT-PCR, histopathological and western blot analysis. The level of blood chemistry including GOT/GPT, albumin, and total bilirubin were significantly exchanged comparing to control and Group I/Group II. The expression of albumin and collagen mRNA were significantly exchanged (P<0.05) in both groups. In addition, AFP mRNA expression decreased more after recovery periods than Group II. XIAP was expressed constitutively in normal rat liver as well as DEN-induced Groups I and Group II. In addition, XIAP expression increased more in Group I with 4 weeks recovery periods than Group I. However, XIAP expression shown to increase in Group lI, otherwise, it was decreased in Group II with 10 weeks repair periods. Taken together, these results suggest the alteration of XIAP expression could be involved in hepatocellular carcinogenesis.

This study was conducted to investigate the dietary effects of germinated and fermented (with Monascus pupureus) soybean screenings (GFS) on growth performance and meat quality in broiler chicken. A total of 750 1-day-old Ross ${\times}$ Ross male broiler chicks were randomly allocated into five groups (five replications with 30 birds each) and fed experimental diets for 5 wks as follows: Group 1, negative-control (antibiotics-free diet); Group 2, positive-control (negative-control with 10 ppm of Avilamycin); Group 3, negative-control with 0.3% GFS; Group 4, negative-control with 0.5% GFS; Group 5, negative-control with 1% GFS. The final body weight of each group fed a diet containing 1% GFS was significantly higher than that of the negative-control group. The feed conversion ratios of all groups fed diets containing GFS and the positivecontrol group were significantly improved compared to the negative-control group during the whole period (p<0.05). The relative weights of various organs along with the activities of serum glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) were not influenced by the dietary treatments. The levels of total serum cholesterol in groups fed diets containing 0.5% and 1% GFS were more significantly lowered compared to those of the control groups without GFS (p<0.05). There were no significant differences in the cecal microflora profiles among the groups. Further, the dietary treatments did not influence the physico-chemical properties of the edible meat, including the shear force, pH, meat color (CIE $L^*$, $a^*$ and $b^*$), and content of malondialdehyde (MDA). Cooking loss of breast muscle in the groups fed GFS was significantly lowered compared to that of the negative control group (p<0.05). These results indicate that dietary GFS could improve growth performance in broiler chicken and may affect meat quality in some instances.

본 연구는 EP사료와 MP사료를 공급한 강도다리의 성장과 혈액성분의 변화 조사를 통해 강도다리 양식에 대한 기초 자료를 제공하고자 수행되었다. 실험 개시 전과 종료 후에 강도다리의 무안측 생체무늬를 사진 촬영하여 개체 인식 가능성을 확인한 바, 생체 무늬의 큰 변화가 관찰되지 않아 향후 강도다리를 비롯한 넙치류에서의 개체 인식 수단으로 활용 가능할 것으로 여겨진다. 증중량과 일간 성장률은 MP 사료 시험구가 EP사료 시험구보다 높았으며, 혈액성분 중 삼투압과 관련된 전해질 농도, 코티졸 농도, 간장 건강도 지표, 영양 지표 등은 시험구 간 차이가 나타나지 않았다. 그러나 공급 사료의 지질 함량이 상대적으로 많았던 MP사료 시험구의 혈중 유리지방산 농도가 높게 나타나, 증중량이나 일간 성장률이 높았던 것과도 관련이 있을 것으로 여겨지며, 수온이 낮은 수역에 주로 서식하는 강도다리가 지질을 에너지원으로 효과적으로 활용한다는 것을 확인할 수 있었다. 두 사료 시험구에서 모두 일간 성장률이 큰 그룹이 낮은 그룹에 비해 혈중 유리지방산 농도가 높았던 것에 대한 상관성에 대해서는 향후 더욱 상세한 검토가 필요할 것으로 생각한다.

본 연구는 새송이 버섯을 첨가하여 만든 어묵이 체내 지질 대사와 효소 활성에 미치는 영향을 알아보고자 수컷 Sprague-Dawley 흰쥐 30마리를 대상으로 고콜레스테롤(1%)첨가 기본식이, 30% 일반어묵 첨가 식이와 40% 새송이 버섯 첨가 오징어 어묵 식이를 급여하였다. 평균 식이 섭취량은 대조군, 일반 어묵군, 새송이 버섯 첨가 오징어 어묵군에 따른 각 군 간의 유의적인 차이는 볼 수 없었다. 체중 증가량과 식이효율은 대조군에 비해 실험군 모두 유의적으로 감소하는 경향을 보였다. 혈장 중성지질과 총 콜레스테롤, 동맥경화지수(A.I), GOT, GPT 수준은 대조군이 새송이 버섯 첨가 오징어 어묵군에 비해 유의적으로 높게 나타났다. HDL-콜레스테롤의 경우 새송이 버섯 첨가 오징어 어묵군이 대조군과 일반 어묵군보다 낮게 나타났고, 간조직의 콜레스테롤 및 중성 지방 농도는 유의적으로 차이가 없는 것으로 나타났다. 혈장과 간조직 TBARS 수준은 대조군보다 새송이 버섯 첨가 오징어 어묵군에서 유의적으로 낮은 수치를 보였다. 항산화 효소 활성도에서 SOD활성도는 대조군과 일반 어묵과의 유의적인 차이가 없었으며, CAT활성도는 대조군보다 새송이 버섯 첨가 어묵이 유의적으로 높게 나타났으며. GPx활성도 역시 유의적으로 높게 나타났다. 이 결과들을 종합해 보면, 고콜레스테롤혈증 흰쥐에서의 새송이 버섯 첨가 오징어 어묵은 전반적인 지질대사 개선과 함께 SOD, CAT, GPx와 같은 항산화 효소의 활성을 증가시켜 항산화 방어계에도 긍정적인 효과를 나타냄으로써 앞으로 고콜레스테롤 혈증 예방 등의 혈관 순환기 계통 질병을 예방하기 위한 식품으로써의 활용이 기대된다.

Background and Objectives: Subacute necrotizing lymphadenitis or Kikuchi's disease has now become recognized in many parts of the world as a well-defined clinicopathologic entity. It typically affects cervical lymph nodes of young women, and subsides spontaneously within a few months without recurrences. The purpose of this study is to report the clinicopathologic finding, radiologic finding and many laboratory tests to elaborate the criteria that are useful in distinguishing this entity from inflammatory disease, granulomatous disease, lymphoma, malignant disease. Material and Methods: Authors evaluated 22 patients, who were diagnosed as subacute necrotizing lymphadenitis on excisional biopsy or fine needle aspiration cytology with retrospective chart review. Results: The patient population consisted of 21 women and 1 men. The mean age was 25 years old(range 17 to 42 years). All patient had palpable neck mass and associated fever, headache, weight loss, otalgia, diarrhea, night sweating. and associated disorder is dermatitis, hepatitis B, SLE, Hashimoto's thyroiditis, albinism et al. The multiple bilateral involvement of cervical lymph node was 20 cases(91%) and multiple unilateral 18 cases(82%), multiple bilateral 2 cases(9%). Solitary involvement was 2 cases(9%), mean size of involved lymph node was 2.0cm. In laboratory tests, leukopenia 17 cases(72%), elevated ESR 12 cases(54%), elevated GOT, GPT 3 cases(13%). In CT finding, lymph nodes enhanced in homogeneous fashion, and there was no evidence of central necrosis. Conclusion: Subacute necrotizing lymphadenitis, Kikuchi's disease may be easily confused clinically, pathologically, radiologically with malignant lymphoma, inflammatory disease, granulomatous disease. We should consider open biopsy of lymph node in the patient which had unilateral multiple cervical lymph node and in laboratory tests, were leukopenia, elevated ESR, especially in young women. otherwise, result of fine needle aspiration biopsy is nonspecific, excisional biopsy is recommended in order to differentiate other disease.

Streptozotocin(STZ)으로 유도된 당뇨 쥐에서 마늘, 양파 등 Allium 속(屬) 식물에 함유되어 있는 N-acetyl cysteine(NAC), S-allyl cysteine(SAC), S-ethyl cysteine(SEC) 및 S-methyl cysteine (SMC) 등 organocysteine 화합물이 혈당과 포도당 내성 및 혈장과 간 조직의 지질 농도에 미치는 영향을 살펴보았다. NAC, SAC, SEC 및 SMC 등 cysteine 화합물 투여는 STZ 당뇨로 인한 다음, 다식, 다뇨 및 체중 감소 증세를 일부 개선시키고, 내당능을 향상시키는 결과를 보였다. 당뇨 쥐에 있어서 cysteine 화합물의 투여는 혈장 총 콜레스테롤과 중성지질 농도에는 큰 영향을 미치지 않았으나, HDL-cholesterol의 농도의 증가와 LDL-cholesterol 농도의 감소를 통해 전반적으로 동맥경화 유발지수를 개선시키는 결과를 보였으며, 간 조직 중성지질 농도를 낮추어 당뇨군의 지방간 증세를 완화시킴과 아울러 혈장 GOT, GPT 활성을 감소시켜 간 보호 효과를 보였다. 이들 결과를 볼 때 NAC, SAC, SEC 및 SMC 등 cysteine 화합물은 STZ에 의해 유도된 당뇨 쥐에 있어 당대사 조절과 함께 지질대사 조절을 통해 지질대사 이상으로 인한 합병증 유발을 완화시킬 수 있는 가능성이 있다고 사료된다.
