  • 高麗人蔘抽出液의 효과를 관찰하고자 실시되었다. 대조군은 15일 동안에 관찰되었으며 인삼투여군은 Sarcoma-180에 감염된 마우스에 인삼추출액을 매일 경구투여하여 15일째에 관찰 비교하였다. 그 결과는 아래와 같다. 1) 肉腫癌쥐에 있어서 癌감염후 15일간 赤血球와 血小板의 수에는 有意性變化가 없었으나, 白血球는 初期에 증가되다가 中期 이후부터는 급격히 감소하였다. 그러나 人蔘抽出液處理群에서는 심한 감소현상은 나타나지 않았다. 이는 白血球가 生體防禦의 작용을 한다는 이론에 人蔘抽出液이 이를 보조해 준 것으로 판단된다. 2) 肉腫癌쥐의 血淸蛋白은 非選擇性 蛋白漏出型 血淸蛋白盆畵像을 보였다. 人蔘抽出液處理群에서도 비슷한 현상을 보였으나 對照群에 비하여 심하지는 않았다. 이는 人蔘抽出液이 肉腫癌쥐에 肉腫癌의 發育에 있어서 약간의 遲延性 내지는 免疫性을 가지게 하는 것으로 사료된다. 3) 肉腫癌쥐에 있어서의 serum cholesterol의 함량은 中期까지는 증가되다가 末期에서는 감소되었다. 그러나 人蔘抽出液處理群에서는 약간의 증가현상을 보였다. 末期에 감소되는 현상은 여러 가지 원인중 특히 攝食量의 부족에 기인되는 것으로 추측되는바, 인삼추출액이 담癌體에 대하여 약간의 耐性을 가지게 함으로서 攝食量이 줄지 않음에 기인되는 것으로 추측된다. 4) 肉腫癌쥐의 serum total lipid는 癌이 진전됨에 따라서 증가되었다. 그리고 $\\alpha-, \\beta-$lipoprotein은 감소현상을 보였으나 pre $\\beta$-lipopotein은 급격히 증가되었다. 人蔘抽出液處理群에서는 對照群에서의 初期의 값을 보여주었다. 이러한 현상 역시 人蔘抽出液이 위와 같은 이론에 의해서 生體를 보호해 준 것으로 추측되며 肉腫癌에 대하여 약간의 耐性을 갖게한 결과로 판단된다.

  • The aims of this study were to identify the mothers educational needs when they have children who have had open heart surgery in congenital heart disease, to identify the children's characteristics with this problem, and also to provide the basic information on the development of the educational program for the mothers. The subjects of the study were 101 mothers of children and their children hospitalized with congenital heart disease in pediatric wards of G. University Hospital in Inchon and S. Hospital in Puch on from June to November 2000. The study used a Likert-type questionnaire with 39 questions which was based on a previous questionnaire developed by Lee Mi-ryun(1989) for adult open heart surgery patients. The reliability of the questionnaire was Cronbach' ${\alpha}$=.9375. The data were collected directly from mothers of the patients in wards. The t-test, ANOVA was adopted for the data analysis. The key results of the study are as follows : 1) The average age of the children was 32.90 months. The majority of the children are male and weighted 3.0-3.5Kg at birth. Most of the children had VSD(29.7%), and 10.9% of children had a family history of heart disease. 2) An average score of 4.62 out of a maximum of 5.00 was recorded for the educational needs of the children's mother. The highest score of 4.69 was for home care after discharge followed by a score of 4.67 for diagnosis and prognosis on congenital heart disease. And pre-post operation care scored 4.51. The mean scores of single-question items of educational need were, in order, 4.81 for immunization after operation, 4.80 for recovery process, and 4.77 for prognosis of the disease. The score of 4.18 for measurement of intake and output was the lowest. 3) The analysis on the children's mothers educational needs by social-demographic characteristics such as sex, age of patient and mother, economical status, educational status, number of child, hospitalization times, and hospitalization cause showed no significant difference statistically, but there was a significant difference between mothers with jobs and with out jobs.

  • It is important to asess the risk factors of parenting and provide early intervention for promotion of the maternal caretaking ability. The purpose of the study was to identify the maternal burden of caretaking, the supporting and the educational need for the caretaking activities of the mother of infant. Sixty three mothers of infants who visited the wellbaby clinic of S university hospital and one health center during the period of November 1st, to 30th in 1996 comprised the subjects of this study, Data were gathered through the instruments that were developed by researcher. Statistical analysis of this study was used ANOVA and Pearson correlation. The results were as follows : 1) The mean score of the maternal burden of caretaking was 22.06. The maternal burden of caretaking was significantly high in the mothers who had vaginal delivery compare with the mothers who had caeserean section and in the muthers who gave artificial feeding compare with the group of breast or mixed feeding. 2) The mean score of the support need for the caretaking activities was 30.69. The support need for the caretaking activities was significantly high in the mothers who had the second child, compare with the mothers who had first or third child. And the support need for the caretaking activities was significantly high in the mothers who had caretaking help compare with the mothers who had no caretaking help. The specific subjects of 'mother-infant interaction', 'immunization' and 'prevention of accident' on the support need for the caretaking activities were relatively high. 3) The mean score of the educational need of caretaking activities was 29.3. The educational need of caretaking activities was significantly high in the mother who had the second child compare with the mothers who had first or third child. And the educational need of caretaking activities was significantly high in the mothers who had caretaking help compare with the mothers who had no caretaking help. The specific subjects of 'mother-infant interaction', 'emergency care' and 'prevention of accident' on educational need of caretaking were relatively high. 4) The maternal burden of caretaking was not correlated with the support need or the educational need of caretaking activities. But the support need of caretaking activities was significantly correlated with the educational need of caretaking activities. 5) The support and educational need of caretaking activities were significantly high in the mothers who wanted home care for caretaking their infants. Through the study, it was found that there is considerable maternal burden of caretaking as well as the support and educational need on the caretaking activities in the mothers whose child is young. Therefore developing the systematic and effective program is needed to meet the mother's need. The results of this study will be useful resources to develop the program. On the other hand, it can be recommanded that home health care will be one of the approach to support the mothers caretaking activities.

  • CD40L를 발현하는 KU812세포와 CD40를 발현하는 항원 특이적 B 세포의 배양을 통해 IgE 클라스 스위치가 유도된다. 본 연구자는 체외면역법에 의해 건강인의 말초혈액을 이용하여 쌀 알레르겐 특이적 IgM 항체를 생성하는 B 세포주를 수립하였다. 본 연구에서는 KU812세포에 의한 쌀 알레르겐 특이적 IgE 항체의 유도를 시도하였다. 배양 전, 쌀 알레르겐 특이적 B 세포주, RA9G11과 PMA와 ionomycin을 6시간 처리하여 활성화된 KU812세포에서 CD40와 CD40L 발현량을 flow cytomerty를 통화여 각각 확인하였다. RA9G11세포와 활성화된 KU812세포는 높은 수준의 CD40와 CD40L를 각각 발현하였다. 쌀 알레르겐 특이적 IgE항체 합성 유도를 위해, 여러 가지 농도의 IL-4 존재하에, RA9G11세포와 활성화된 KU812세포를 12일 동안 배양하였다. IgE 정상영역의 mRNA 발현량과, 쌀 알레르겐 특이적 IgE 항체 생성 세포가 모든 조건에서 확인되었으며, 특히 50U의 L-4 농도 하에서 같은 비율의 RA9G11과 활성화된 KU812세포를 배양했을 때, IgE 합성이 가장 높았다. 따라서 활성화된 KU812세포에 의한 쌀 알레르겐 특이적 IgE 합성은 알레르기 질환의 치료 및 예방에 관한 연구에 기여할 것으로 사료된다.

  • 본 연구를 통하여 규칙적인 수영 트레이닝이 체중의 감소를 일으켰으며(온수 및 냉수), 특히 냉수 훈련이 큰 감소를 나타내었다. 온수 훈련군에서는 $INF-\gamma$의 감소를 유발하여 림프구의 증식을 Th0에서 Th2 쪽으로 유도한다는 사실을 알 수 있었으며, 이로 인해 결핵균을 감염시켰을 경우 오히려 폐와 비장에서 결핵균의 수가 현저히 증가하는 사실을 알 수 있어, 수영 훈련군에게서의 결핵균 감염 시 대조군에 비해 균수가 현저히 증가함을 알 수 있었다. 하지만 냉수 훈련군에서는 통제군에 비해 $INF-\gamma$의 현저한 증가를 보여, 결핵균 감염 시 폐에서 결핵균 수가 감소함을 확인 할 수 있었다.

  • Experimental autoimmune encephalomyelitis (EAE) is an inflammatory disease in the murine central nervous system (CNS) and has long been used as an animal model for human multiple sclerosis. Development of EAE requires coordinated expression of a number of genes that are involved in the activation and effector functions of inflammatory cells. Galectin-3 (Gal-3) is a member of the betagalactoside- binding lectin family and plays an important role in inflammatory responses through its functions on cell activation, cell migration or inhibition of apoptosis. We investigated the functional role of Gal-3 in EAE mice following immunization with myelin oligodendrocyte glycoprotein $(MOG)_{35-55}$ peptide. During the peak stage of EAE, the localization of Gal-3 in inflammatory cells markedly increased in subarachnoid membranes and perivascular regions of CNS. In contrast, Gal-3 was weakly detected in cerebrum and spinal of the recovery stage of EAE. Consistent with this finding, western blot analysis revealed that Gal-3 expression was significantly increased at the peak stage while it was slightly decreased at the recovery stage in the CNS. In addition, the population of $CD11b^{+}$ macrophage expressing Gal- 3 in spleen of EAE mice was markedly increased compared with control mice. In fact, most of activated macrophages isolated from spleen of EAE mice expressed Gal-3. Taken together, our results demonstrate that the over-expression of Gal-3 in activated macrophages may play a key role in promoting inflammatory cells in the CNS during EAE.
