In this work, imaging and study of elastic property of the living cell was performed. The motivation of this work was to seek the possibility of exploiting Young’s modulus as a disease indicator using Atomic Force Microscope (AFM) and also to gain fundamental understanding of cell mechanics for applications in medical nanorobots of the future. L-929 fibroblast adherent cell was used as the sample. Imaging condition in cell culturing media environment was done in very low speed (20 μm/s) compared to that in the ambient environment. For measuring the Young’s modulus of the living cell, AFM indentation method was used. From the force-distance curve obtained from the indentation experiment the Young’s modulus could be derived using the Hertz model. The Young’s modulus of living L-929 fibroblast cell was 1.29 ± 0.2 kPa.

In this work, imaging and study of elastic property of the living cell was performed. The motivation of this work was to seek the possibility of exploiting Young's modulus as a disease indicator using Atomic Force Microscope (AFM) and also to gain fundamental understanding of cell mechanics for applications in medical nanorobots of the future. L-929 fibroblast adherent cell was used as the sample. Imaging condition in cell culturing media environment was done in very low speed ($20{\mu}m/ s$) compared to that in the ambient environment. For measuring the Young's modulus of the living cell, AFM indentation method was used. From the force-distance curve obtained from the indentation experiment the Young's modulus could be derived using the Hertz model. The Young's modulus of living L-929 fibroblast cell was $1.29{\pm}0.2$ kPa.

( Hyung Il Kwon ),( Eun Jin Kim ),( Hyun Woo Kim ),( Hyun Chul Park ),( Jeong Eun Kim ),( Joo Yeon Ko ),( Young Suck Ro ) 대한피부과학회 2013 대한피부과학회 학술발표대회집 Vol.65 No.2
Background: Cyclosporine (CS) has been used for various skin diseases including psoriasis and atopic dermatitis. However, dermatologists are reluctant to use CS in clinics because of the adverse effects. Objectives: To investigate the adverse effects of CS for dermatological uses. Methods: A retrospective study of 1,335 patients with CS treatment was performed. Results: 15.6% of patients showed adverse effects. Gastrointestinal (GI) symptoms were the most common adverse effect. Other adverse effects included hypercholesterolemia, hypertrichosis, headache, hypertension, hypertriglyceridemia in order of frequency. Hypercholesterolemia was more often in men, but GI symptoms and hypertrichosis in women. Hypercholesterolemia, hypertriglyceridemia and GI symptoms were more common in adults, but hypertrichosis in young. GI symptoms and headache occurred more often within three months of CS treatment, but hypertension, hypercholesterolemia and hypertriglyceridemia after three months. Hypertrichosis was more often in group with low initial dose. GI symptoms occurred more often with lower CS cumulative dose group and hypertension and hypertriglyceridemia in higher CS cumulative dose group. Conclusion: Comparing to previous studies, the frequency of adverse effects of CS was proven to be low. Therefore, in dermatologic field, we suggest that CS is relatively safe with periodic follow-up.

Agranulocytosis, one of the major side effects of antithyroid a gents, probably occurs in less than 0.25% of cases treated with antithyroid agents. It usually occurs within the first several weeks or months after the initiation of therapy, when drug dosage is higher. Most reported cases of agranulocytosis have occurred during the first 3 months of therapy. We describe here a rare case that did not experience the side effect for 6 years of antithyroid agent treatment but presented with agranulocytosis in one month after re-exposure. It suggests that the major side effect such as agranulocytosis can occur in patients who had undergone prior uneventful antithyroid drug therapy.
Allylthiopyridazine 유도체 합성 및 간보호 효과
권순경,이은방,김미경,박영남 德成女子大學校 藥學硏究所 1998 藥學論文誌 Vol.9 No.1
Allylthio group of the sulfur compounds of garlic oil plays an important role for prevention and treatment of hepatic diseases to be introduced by toxic substances or carbon tetrachloride. Thus allylthio group as a pharmacologically active group was introduced into pyridazine nucleus and a substituent such as halogen or alkoxy was also introduced into the para-posi-tion of allylthio group. Three allylthiopyridazine derivatives were synthesized and their hepatoprotective activities were screened in rat. Under the three compounds (6, 7, 8), 7 and 8 (methoxy-, ethoxy-substituent) are hepatoprotective, but 6 (chloro-substitu-ent) is negative.

Sarcoidosis is a multisystem granulomatous disease of unknown cause, characterized by enhanced cellular immune process at the sites of involvement. Three Cases of sarcoidosis involving vilateral hilar lymph nodes, skin and lungs were presented. Each case was confirmed by characteristic non-caseating granuloma in biopsied thoracic lymph nodes and skin. They had abonormal pulmonary function test, elevated serum angiotensin converting enzyme, hilar and mediastinal lymphadenopathy and compatible clinincal features of sarcoidosis.

This study was conducted with the need for preparing active measures of the central government and the local government to deal with low fertility and aging society issues and with the purpose of setting the related policy direction. The issues of recent low fertility and aging are experienced globally and the decline of population is detected in Korea as well. Therefore, multilateral efforts are taken to deal with the imminent phenomenon at the governmental level. Incheon Metropolitan City, with its population of 3 million, is one of the big cities in rapid progress of low fertility and aging phenomenon. While the total fertility rate of Incheon is 1.21 (Statistics Korea, 2015) which is the similar level with the national average, it is far below the population replacement level and has continuously been recording the low figures since 2000. Besides, the elderly population rate in 2014 was 10.3%, a 5.5% increase compared to the previous year. It is expected that the population aging would be accelerated for the next 30 years and it is forecasted that the elderly population rate of Incheon would reach around 30% by 2040. According to the survey results of general citizens on this population change, more than half of the respondents seriously recognized the shift to the low fertility and aging society and demanded the measures to deal with the issues. To set the policy direction in association with the central government within the local region, this study explores the tasks to deal with the policy and the demands for the policy in Incheon Metropolitan City. 본 연구는 저출산・고령사회 이슈에 대응하여 중앙정부와 더불어 지자체의 적극적 대책마련의 필요성과 정책방향성 수립을 위한 목적으로 시도되었다. 최근 저출산과 고령화의 문제는 전 세계적으로 경험되는 문제이며 또한 우리나라에서도 인구의 변화가 감지되고 있는 상황이다. 이에 정부차원에서 이미 저출산과 고령화 문제를 경험하고 대처하고 있는 선진국의 사례를 검토하면서, 다가올 현상에 대해 대응할 수 있기 위한 다각적 노력이 진행되고 있다. 인천시는 인구 300만 시대가 임박하는 상황에서 저출산과 고령화 현상이 빠르게 진행되고 있는 대도시중 하나이다. 인천시의 합계출산율은 1.21명으로 전국평균과 동일한 수준에 있지만 인구대체수준에는 크게 못 미치는 상황이며, 2000년 이래 지속적으로 낮은 수치를 기록하고 있다. 또한 2014년 노인인구 구성비는 10.3%로 전년대비 5.5% 증가되었으며, 향후 30년간 고령화가 빠른 속도로 진행될 것으로 전망되며 오는 2040년 인천의 고령인구비율이 약 30%로 예측되고 있다. 이러한 인구변화에 대해 일반 시민들에게 저출산・고령화 사회로의 변화는 실태조사결과 절반 이상이 심각하게 인지하고 있는 상황이며, 이에 대한 대책마련을 요구하고 있는 것으로 나타났다. 본 연구에서는 중앙정부와 연계성 있는 지역 내 정책방향 수립을 위해 인천시 사례를 들어 지역에서의 정책에 대한 시민체감도와 정책 수요, 또 정책대응의 과제를 살펴보고자 한다.
