        食用油脂는 健康維持에 必須的인 營養素이다. 그러나 食用油脂는 脂肪을 構成하는 脂肪酸의 種類와 攝取하는 量에 따라 健康을 保衛하는 必須的인 食品의 成分이 되기도 하고 有害한 影響을 끼칠 수도 있어서 脂質代謝와 關連된 疾病 뿐만아니라 老化를 促進하고, 乳房癌, 大腸癌等의 癌發生과도 關連된 것으로 밝혀져 있다. 本 硏究는 우리生活環境에서 食用으로 接할 수 있는 10種의 油脂에 對한 免疫生物學的인 活性에서 究明한 結果 對照群인 참기름食餌群에 比해 올리브유食用群은 全般的으로 體液性 및 細胞性免疫을 有意性있게 增加시켰으나, 大食細胞의 活性과 末梢循環白血球數는 有意性없는 減少를 보였고, 動物性 油脂인 牛脂食餌群과 植物性 油脂인 옥수수기름食餌群, 들기름食餌群, 米糠油食餌群, 大豆油食餌群, 菜種油食餌群 및 고추씨기름食餌群에서는 全般的으로 體液性 및 細胞性免疫, 大食細胞의 活性 및 末梢循環白血球數를 有意性있게 減少시켰다. This study was performed to investigate the effects of edible oils and fats on the immunobiological responses in ICR male mice. Ten groups of experimental diets, such as sesame oil diet, beef tallow diet, lard oil diet, olive oil diet, corn oil diet, perilla oil diet, rice polishing oil diet, soybeen oil diet, rape seed oil diet, and red pepper seed oil diet were fed adlibitum to the ICR male mice for 27 days. The results of this study were summarized as followings. 1. Both humoral and cellular immune responses, phagocyte activity, and number of leukocytes in sesame oil group were increased. However, the increasing rate of body weight and the weight retios of spleen and thymus to body were generally decreased. 2. Hemagglutination titer(HA) and rosette forming cell(RFC) of the beef tallow group and the lard group were significantly lower than the sesame oil group(P<0.01), but the lard group significantly increased Arthus reaction and delayed type hypersensitivity(DTH)(P<0.01). 3. Arthus reaction, DTH, and RFC of the olive oil group were significantly higher than the sesame oil group(P<0.01). 4. DTH of the corn oil group was significantly higher than the sesame oil group(P<0.01) whereas phagochyte activity was significantly lower(P<0.01). But no statistically significant differences were found between the two groups in the humoral immune response. 5. HA, PFC, DTH, RFC, phagocyte activity, and number of leukocytes of the perilla oil group and the rice polishing oil group were significantly lower than the sesame oil group(P<0.01). 6. Both humoral and cellular immune responses, phagocyte activity, and number of leukocytes of the soybeen oil group, the rape seed oil group, and the red pepper oil group were significantly lower than the sesame oil group(P<0.01).

      • 마우스에 있어서 Olive Oil의 食餌가 免疫反應에 미치는 影響

        안영근,박병철,김정훈,이상근,박영길 원광대학교 식품약품안전성연구소 1991 食品藥品安全性硏究 Vol.4 No.-

        This study was performed to investigate the effect of olive oil diet on the immune response in ICR male mice. Experimental diets of 4 groups were fed ad libitum to the ICR male mice for 27 days. The results of this study were summarized as followings: 1. 10% Olive oil diet group as compared with the control diet group significantly decreased liver weight rate but significantly increased hemagglutination titer (HA), Arthus reaction, delayed type hypersensitivity reaction (DTH), rosette forming cell (RFC), and phagocyte activity. 2. 20% Olive oil diet group as compared with the control diet group significantly increased body weight gain, liver weight rate, and HA but significantly decreased Arthus reaction, DTH, RFC, phagocyte activity, and peripheral circulating white blood cell (WBC). 3. 30% Olive oil diet group as compared with the control diet group significantly increased liver weight rate but significantly decreased body weight gain, Arthus reaction, plaque forming cell (PFC), DTH, RFC, phagocyte activity, and WBC. The results showed that the increase of olive oil doses significantly decreased humoral and cellular immune responses, phagocyte activity, and WBC.

        Background : The inflammation is an important feature of atherosclerotic lesions, and peripheral monocytosis is known to be associated with increased coronary events and poor prognosis in acute myocardial infarction (AMI). The aim of this study was to determine the significance in clinical and angiographic outcomes, success rate of the percutaneous coronary intervention (PCI) and major adverse cardiac events and event-free survival rate after PCI according to the value of peripheral monocyte on admission. Methods : A total of 127 patients with AMI who underwent PCI between June 2000 and June 2001 at Chonnam National University Hospital were divided into two groups: Group I (n=63, 61.7±10.9 years, male 71.4%) with normal monocyte count (<900/㎣, mean value=536±202/㎣) on admission and Group Ⅱ (n=64, 61.7±13.4 years, male 78.1%) with elevated monocyte count (≥900/㎣, mean value=1,140±260/㎣) on admission. Results : Baseline ejection fraction was lower in Group Ⅱ than in Group Ⅰ (Group Ⅰ; 53.3±13.0% vs Group Ⅱ; 45.0±11.7%, p=0.014). The value of C-reactive protein, troponin-T and troponin-I was higher in Group Ⅱ than in Group Ⅰ (Group Ⅰ; 2.8±1.9 mg/dL, 1.98±1.53 ng/mL, 18.3±17.7 ng/mL vs Group Ⅱ; 5.3±5.0 ㎎/dL, 3.34±2.54 ng/mL, 43.1±24.0 ng/mL, p=0.034, 0.020, 0.006, respectively). The incidence of target lesion revascularization was higher in Group Ⅱ than in Group I during hospitalization and during 6-month clinical follow-up after PCI (1.6% vs 12.5%, 19.0% vs 31.3%, p=0.012, 0.015, respectively). The event-free survival rates were lower in Group Ⅱ than in Group Ⅰ during hospitalization and during 6-month follow-up after PCI (96.8% vs 84.4%, 71.4% vs 53.1%, p=0.006, 0.008, respectively). Conclusion : Peripheral monocytosis is associated with LV dysfunction and higher incidence of target lesion revascularization and worse mid-term event-free survival during hospitalization and at 6 months after PCI in patients with AMI.

      • 중ㆍ고년여성의 하지 근 기능과 요부 및 대퇴근 횡단면적의 상관관계

        김창근,이수경,권영우,박정배 한국체육대학교 체육과학연구소 2001 국제학술대회논문집 Vol.20 No.1

        The purpose of the present study was to investigate the relationship between isokinetic muscle function and muscle cross-sectional area (CSA). Twelve women participated in the present study, divided young (n=6, 23.7±1.9 year) and elderly women (n=6, 60.3±6.8 year). Isokinetic strength (power, strength, endurance) and CSA (psoas major and thigh muscles) measured with dynamometer and computerized tomograph, respectively. Cross-sectional area of psoas major muscle in elderly group revealed markedly smaller than in young group, but thigh muscle was not the case. Muscle CSA in young women correlated between power and endurance and psoas major muscle, as well as between muscle strength and CSA of thigh muscle. But no correlation occurred between strength and cross sectional area, except endurance which was highly correlated between CSA and endurance. In conclusion, aging decreases muscle function and CSA. Partially muscle strength correlated with muscle CSA in young women, but no correlation occurred in elderly women. Further study needed to elucidate the exact mechanism related to aging muscle with muscle density and neuromuscular function.

        Previously, Gum Metal (Ti-24(Nb + Ta + V)-(Zr, Hf)-O (at%)) exhibiting an ultralow Young`s modulus, ultrahigh strength and super elasticity was developed by Saito et al., who proposed that three electronic magic numbers, an average electron/atom (e/a) ratio of 4.24, an average bond order (Bo) of about 2.87, and an average “d” electron-orbital energy level (Md) of about 2.45 eV, should be satisfied simultaneously to obtain such “super” properties. The purpose of this study was to find new alloy systems possessing those properties and to examine the effect of beta equivalent content ([Mo]eq) on Young`s moduli of new alloys having the same three electronic numbers mentioned above. It was found that not only three electronic numbers but also [Mo]eq should be considered to obtain a similar Young`s modulus and hardness with respect to the Gum Metal.

        Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.

        Background and aim:Allergic skin test and serum specific IgE are major tools in the diagnosis of atopy. Many factors influence the results of those two studies. We evaluated the correlation between the responses of allergic skin test and the level of specific IgE as related aging process. Methods:234 atopic asthma patients were enrolled and divided into 3 different groups according to their ages. All subjects were performed allergic skin test and measured serum specific IgE. We used only two common antigens, D. farinae and D. pteronyssinus. Results:Positive rates on allergy skin prick test and serum specific IgE reduced as increasing of subject's ages with showing significant agreement rates of results of both tests among 3 different age groups. Conclusion:The aging process may make, not only decrease of the specific cutaneous responses, but decrease of the production of antibodies, and immunologic activities itself.
