This study sought to examine whether physical activity level is associated with health belief-related weight control, exercise self-efficacy, and exercise adherence intention in Korean adolescents. As participants in the survey, a total of 652 male and female participants were recruited from junior high schools in Seoul. Statistical analyses were performed using SPSS Statistics program. The perceived benefit of health belief-related weight control was higher than other variables including perceived severity, barrier, and susceptibility in both genders. Female junior high school students were more susceptible to weight control behavior than male participants. In addition, the perceived benefit and barrier of weight control behavior were positively and negatively related to exercise adherence intention, respectively, in both male and female students. However, health belief was not correlated with physical activity level. These results indicate that positive health belief and weight control behavior may contribute to augmenting intrinsic motivation to exercise, but not genuinely increasing exercise participation. In contrast to health belief, the high level of exercise self-efficacy was found to be correlated with increases in exercise adherence intention and physical activity level. Therefore, education and guidance at home and in school are certainly required to establish desirable health belief and enhance exercise self-efficacy, which lead adolescents to maintain their healthy weight through regular physical activity.

The selective cleavage of phenylsilane by triflic acid gives silyltriflates. The removal of phenyl groups in $Ph_3SiH$ and carbosilane polymer $(Ph_2SiCH_2CH_2CH_2)n$ with one to two equiv of triflic acid leads to formation of mono- and disubstituted silyltriflate ester bonds. Reaction with allylmagnesium bromide produces corresponding derivatives with good yields. An organosilane dendrimer with allylated carbosilane polymer has been synthesized up to G3 using repetitive allylation hydrosilylation cycles.

The silyltriflates$(Ph_{3-n}SiH(OTf)_n)$have been produced by the reaction of triphenylsilane and triflic acid$(CF_3SO_3H)$at low temperature. These highly reactive compounds are a valuable reagent for the synthesis of numerous new functional substituted silane derivatives. The reaction of silyltriflates with alkenyl- and alkynylmagnesium bromide as well as organolithium compounds gave new silanes$Ph_2SiHR(R=\;C(CPh,\;CH=CH_2,\;CH_2CH=CH_2,\; (CH_2)_2CH=CH_2,\;(CH_2)_3CH=CH_2)$in high yields. The hydrosilation of prepared alkenyl- and alkynylsilanesPh_2SiHR$in the presence of a platinum catalyst(Pt/C) at high temperature$(200{\circ}C)$gave carbosilane polymers$((Ph_2SiCH=CPh)_n$and$(Ph_2Si(CH_2)m)n;\;m=2∼4, n{\ge}10)$along with five- and six-membered silaalkane ring compounds derived from intramolecular hydrosilation reactions. All of the prepared compounds are confirmed by NMR, UV, IR and mass spectroscopy as well as elemental analysis.

우리나라가 고령화사회에서 고령사회로, 고령사회에서 초고령사회로 도달하는 시간이 각각 22년과 10년으로 추정되며 선진국에 비해 진입속도가 빠를 것으로 보고 있다. 고령화인구에 따라 일상생활은 물론 지역사회에서의 활동, 더 나아가서는 직업활동을 할 수 없는 기억장애현상인 노인성 치매가 더욱 문제시된다. 따라서 본 연구에서는 우리나라에서 정신 건강 관련하여 이미 이용되고 있거나 민간에서 구두로 알려진 식품 총 100종을 선정하고, 메탄올 추출물에 대하여 prolyl endopeptidase에 대한 활성 저해율을 측정하였다. 그 결과, 40 ppm 농도에서 도토리가 96.0%로 가장 높은 활성 저해율을 보였고, 산딸기가 92.0%, 호두가 73.0%로 나타났으며, 그 외의 나머지 식품들은 56.1%인 녹차를 제외하고는 모두 50% 미만의 수준이었다. 본 연구결과 PEP에 비교적 특이적으로 작용하는 저해제로서 도토리와 산딸기를 확인할 수 있었고, 현재까지 개발되고 보고된 합성 peptide인 PEP저해제와는 달리 천연 식품이란 점에서, 앞으로 이 식품들이 항치매 예방 기작 구명에 유용하게 이용됨과 동시에 치매의 예방을 위한 기능성 식품으로서 이용될 수 있을 것으로 기대된다. This study was performed to find natural foods with high anti-dementia effects from natural plant resources which have been used for mental health. We screened inhibitors of prolyl endopeptidase which could be implicated in the processing of Alzheimer's disease, the principal part of dementia. One hundred natural foods were examined for prolyl endopeptidase inhibitors. Out of them, methanol extract of Acorns and Raspberry inhibited more than 90% of prolyl endopeptidase activity at 40 ppm. Also, methanol extract of Walnut inhibited 73% of prolyl endopeptidase activity at the same concentration. Therefore, the result suggests that these natural foods may have the potential to be used for preventing and treating dementia like Alzheimer disease.

Lymphocytic infundibuloneurohypophysitis was known as a cause of idiopathic central diabetes insipidus. Until recent time, it is characterized into two groups. One has thickening of the pitutitary stalk, enlargement of the neurohypophysis and loss of hyperintense signal of the normal neurohypophysis, the other has only loss of hyperintense signal but not morphological change. A 51-year-old man presented with a one month history of polydipsia and polyuria. The interpretation of water deprivation test was compatible with complete central diabetes insipidus. Endocrinologic examination of the adenohypophysis hormones and its triple stimulation test were normal apart from thyroid stimulating hormone (TSH), which showed low response despite thyrotropin releasing hormone (TRH). Sellar MRI scan disclosed an loss of hyperintense singnal of normal neurohypophysis and about 10 mm-sized nodular mass lesion on neurohypophysis. However, thickness of the pituitary stalk was normal. Pathologic examination demonstrated diffuse infiltration of lymphocytes and plasma cells. No adenomas, menigitis, sarcoidosis or granulomas were present. We supposed that this case was an atypical type of lymphocytic infundibuloneurohypophysitis, which did not belong to any other part of two groups described above.(Korean J Med 61:168-172, 2001)

연구배경:최근 당뇨병의 새로운 치료법으로 시도되고 있는 췌도이식은 충분한 췌도수의 확보와 췌도생존율을 높이기 위한 면역억제제 사용이 제한점이 되고 있다. 본 연구의 목적은 이식 전 충분한 췌도 수의 확보를 위해 분리한 췌도를 냉동보존하는 방법을 확립하고 냉동보존한 백서 췌도세포의 시험관내 그리고 생체내 기능을 조사하였다. 방법:분리한 백서의 췌장소도를 48시간 배양한 후 한 시험관당 췌도세포 1000개씩 나누었다. 냉동보존은 6개의 시험관에 DMSO를 첨가한 후 초 냉각(supercooling), 핵화(nucleation)단계를 거친 후 99% isopropanol과 액체질소가 들어있는 dewer를 이용하여-0.25℃/분의 냉각속도로 -40℃까지 단계적으로 얼린후-70℃ 액체질소 탱크에 보관했다. 해동은 냉동시킨 vial들을 액체 질소 태으에서 꺼내 37℃ 항온조에 담가 급격히 해동시킨 후, 원심분리하여 상층액을 제거하고 각 vial에 0.75M sucrose 용액을 가한 후, 10% fetal calf serum이 함유된 RPMI 1640 media에서 배양하였다 각각 6개의 시험관에서 해동한 췌도들을 광학현미경 및 형광현미경하에서 췌도의 모양과 생존율에 대해 조사하고 인슐린 정적반응을 알아보았다. 또한 분리한 췌도를 냉동보존하지 않고 이식한 경우를 대조군(6마리)과 생체내 기능을 비교하였다. 결과:① 냉동보존후 획득한 췌도의 수와 생존율 해동후 획득한 췌도의 수는 해동시킨 당일날이 902±21, 24시간 배양 후에는 857±16, 72시간 후에는 817±18개로 점차 감소되었다. AO/PI 염색상 각 췌도의 생존율은 냉동 전을 100으로 하였을 때 해동당일, 24시간 후, 72시간 후가 각각 60±5, 80±5, 90±5%로 해동후 3일간 배양하였을 때 냉동전의 수준으로 회복하였다. ② 냉동보존후 췌도의 포도당에 대한 정적 인슐린 분비능:냉동직후 감소된 경향을 보였으나 해동후 3일간 배양한 췌도의 인슐린 분비는 냉동전과 통계적으로 의미있는 차이가 없이 냉동보존 전의 수준으로 회복되었다. ③ 냉동보존후 췌도의 포도당에 대한 동적 인슐린 분비능:냉동보존한 췌도를 해동후 3일째의 인슐린 동적 분비능은 냉동 전과 마찬가지로 자극 인슐린의 반응의 제1기와 2기가 잘 관찰되었다. ④ 냉동보존한 췌도세포 이식 후 혈당 변화:스트렙토조토신으로 유도된 당뇨병 쥐에 췌도이식 후 혈당은 냉동보존한 췌도이식군에서 대조군에 비해 혈당의 조절효과가 더 오래 지속되었다. 결론:소동물에서 단계적 온도 하강법을 이용한 췌도세포 냉동보존법을 확립하였으며 이는 기능, 구조 및 생존율에 큰 이상을 보이지 않았으므로 장차 사람의 췌도세포 동종이식시 부족한 췌도세포수를 극복하고 면역반응을 줄일 수 있는 매우 유용한 방법이 될 것으로 판단된다. Background : Although islet transplantation has been attempted to reverse the state of diabetes, achieving a critical number of islets and modulating the immune response limit the success of islet transplantation. Cryo-preservation of islets offers many important benefits for islet transplantation by collecting islets with a wide variety of HLA phenotypes and islet MHC expression. The aims of this study was to determine the optimal conditions for cryo-preservation by using a controlled cooling method and to evaluate in vitro and in vivo functional properties of the cryo-preserved islets. Methods : Collagenase-isolated, Ficoll-purified islets were cultured for 48 hours. They were aliquoted into freezing tubes (1000 islets per tube), equilibrated with 2M dimethyl sulfoxide (DMSO) in three steps, supercooled, nucleated, and controll-cooled at rate of 0.25℃/min to - 40℃ prior to storage at - 196℃. Rapid thawing and removal of DMSO with 0.75 M sucrose preceded 48 hour of culture and the morphology, viability, glucose-induced insulin secretion, and in vivo function of rats transplanted with cryopreserved islets was reexamined. Results : ① Recovery was 90.2±0.2%, 85.7±0.1% and 81.7±0.1% immendiately after, 24 hours and 72 hours after thawing respectively. The viability was 60±5%, 80±5%, 90±5% immediately after, 24 hours and 72 hours after thawing respectively. ② The glucose-stimulated-insulin secretion (GSIS) tended to decrease immediately after thawing, but GSIS increase to the level of pre-cryopreservation 72 hours after thawing. ③ The in dynamic GSIS, the first and the second phase of insulin secretion were well preserved in islets cultured for 72 hours after thawing. ④ The cryopreserved islets were cultured for 3 days and transplanted into renal sub-capsular space of streptozotocin (STZ) induced diabetic rats. The duration of normoglycemia in the STZ-induced diabetic rats transplanted with cryopreserved islets was significantly longer than of the fresh islets. Conclusion : The optimal condition of cryopreservation using the controlled cooling method was established in rat pancreatic islets. This cryopreservation method can be a feasible approach for human islet transplantation (J Kor Diabetes Asso 26:64~74, 2002).
