Background: Hyperkalemia is a commonly encountered problem in dialysis patients with end-stage renal disease. In this study we evaluated the effect of mineralocorticoid therapy (fludrocortisono acetate) on serum potassium level in the serum of hyperkalemic end-stage renal disease patients. Methods: Fourteen patients on hemodialysis receiving fludrocortisone acetate (FCA) 0.1 mg/day were observed for 2 months periods. Consecutive monthly biochemical profiles were compared for the druration of the pre-and post-treatment of FCA. Result: Fourteen patients with mean age (±SE) of 51.5 years (4 males and 10 females) and mean hemodialysis period of 51.9 months were studied. Mean serum potassium levels significantly fell (p<0.05) during the post-FCA period (5.2±0.66 mEq/L) compared with potassium levels during the pre-FCA (5.8±0.43 mEq/L) period. Pre-and post-FCA values were not different for sodium, chloride, protein, albumin, AST/ALT, glucose, blood nitrogen, creatinine, phosphate and calcium. Conclusions: FCA appears to decrease serum potassium value in patients with end-stage renal disease. These results suggested that FCA could be effective to treat hyperkalemia without any adverse effect in patients undergoing hemodialysis.

Pmpose: To investigate the characteristics of Myers-Briggs Type Indicator (MBTI) in premedical students of one medical college and to compare the personality profiles of them with those of other studies which involved the K-orean university students and other country population. Mateiials and Methods: The MBTI was used to measure the personality profiles of premedical students at the Center for Teaching & Leaming of Chosun University. One hundred and twenty five premedical students participated in this study and the MBTI profiles of them were compared to those of K-orean university students (1,441 persons), i.e. their potential patients and those of the United Kingdom (UK.) Population (1,634 persons) and a sample of UK- doctors (313 persons) of one medical college involved in other studies. Results: The premedical students had a preference for Introversion (62%) rather than Extraversion (38%), Sensing (70%) rather than Intuition (30%), Thinking (66%) rather than Feeling (34%), and Judging (57%) rather than Perceiving (43%). There were more Thinking (66% vs 57%, p=0.071) in the premedical students than in K-orean university students with borderline significance. There were significantly more Thinking (66% vs 46%, P=0.000) and more Introversion (62% vs 48%, p=0.002) than in UK- adult population. Also there were significantly more Sensing (62% vs 48%, p=0.002), significantly less Judging (57% vs 68%, P=0.034), and more Introversion (62% vs 53%, 0=0.094) with borderline significance than in UK doctors. But no difference was shown in Thinking between the premedical students and UK- doctors, Conclusion: The personality profiles of the premedical students in this study differed in Thinking with borderline significance from K-orean university students and significantly differed from the UK adult population in Thinking and Introversion showing the cultural difference. No difference of Thinking between the premedical students and UK doctors despite of cultural difference suggests the correlation between the Thinking and medical professional choice.

Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 1-15, 2004. The purpose of this study was to investigate the kinematic variables of the upper part of the body for 8 elderly men during walking. For this study, kinematic data were collected using a six-camera (240Hz) Qualisys ProReflex system. The room coordinate system was right-handed and fixed in space, with righted orthogonal segment coordinate systems defined for the head, trunk, and pelvis. Based on a rigid body model, reflective marker triads were attached on the 3 segments. Three-dimensional Cartesian coordinates for each marker were determined at the time of recording using a nonlinear transformation(NLT) technique with ProReflex software (Qualisys, Inc.). Coordinate data were low-pass filtered using a fourth-order Butterworth with cutoff frequency of 6Hz. Three-dimensional angles of the head, trunk, and pelvis segment were determined using a Cardan method. On the basis of each segment angle, angle-angle plot used to estimated the movement coordinations between segments. The conclusions were as follows; (1) During the support phase of walking, the elderly people generally kept their head the flexional and abductional posture. Particularly, the elderly displayed little internal/external rotation. (2) The elderly people showed extensional and external rotation postures in the trunk movement. Particularly, It showed the change from adduction into abduction at the heel contact event of the stance phase. (3) The elderly people showed almost same pelvis movement from the flexion into extension, from the abduction into adduction, and from internal rotation into external rotation at the mid stance and toe off of the stance phase.

페그인터페론과 리바비린 병합요법은 만성 C형 간염의 일차 치료법이다. 저자들은 만성 C형 간염 환자에서 페그인터페론 과 리바비린 병합 요법 중에 발생한 벨마비 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 환자는 5년 전부터 만성 C형 간염을 앓아온 48세 남자이며, PEG-IFN α-2a 135μgm 피하주사 주1회와 하루 1200㎎의 리바비린을 투여하였다. 치료시작 후 9개월째 환자는 오른쪽 안면의 근력약화를 호소하였으며 벨마비로 진단되었다. 페그인터페론과 리바비린 병합요법을 지속하면서 관찰하였다. 환자의 벨마비는 페그인터페론 치료를 중단하지 않았음에도 3개월후 증상이 회복되고 이후 벨마비 재발 없이 현재 경과관찰 중이다. 만성 C형 간염에서 페그인터페론과 리바비린 병합 요법시 벨마비의 발생 가능성을 염두에 두어야 하겠다. A Case of Bell's Palsy Associated with Combination Therapy of Pegylated Interferon Alfa-2a (PEG-IFN) and Ribavirin for Chronic Hepatitis C Virus Infection Pegylated interferon alfa(PEG-IFN α) and ribavirin therapy is the first line treatment for chronic hepatitis C. Mild complications of the therapy are common, but more serious complications are rare. We report here a case of Bell's palsy that occurred in a patient with chronic hepatitis C virus infection during combination therapy of PEG-IFN α-2a and ribavirin. The patient was 49-year-old man with chronic hepatitis C (genotype 1b) for 8 years. He had compensated liver cirrhosis with splenomegaly. Therapy with PEG-IFN α- 2a 135mcg/week and ribavirin 1200mg/day was initiated. After 9 months of the therapy, the patient showed a loss of muscular tone on the right side of his face. A diagnosis of Bell's palsy was made. The Bell's palsy resolved over 3 months despite continuation of the combination therapy.

본 연구는 하수 종말 처리에 의해 발생되는 하수 슬러지를 잔 골재(경량골재)로 사용하여, 폴리머 콘크리트를 제조하여 그 때의 역학적 성질에 대하여 검토하였다. 하수 슬러지는 5일간 110±5℃에서 수분함량 0.1%미만으로 건조한 후 파쇄하여 No.4∼No. 200 번체의 잔골재 표준 시방서 기준에 부합되도록 사용하였다. Pellet는 보통 회전pan에서 만드나, 본 실험에서는 수동으로 제조하였다. 제조한 하수 슬러지 경량 골재는 평균 겉보기 비중은 1.58(g/㎤), 단위용적중량은 1.98(t/㎥)으로 KS F 2534의 경량골재의 절건비중과 단위용적에 따른 분류에 의하면 중위급(medium weight) 경량골재에 속하는 것으로 측정되었다. 또한 잔 골재 중 하수 슬러지 경량 골재를 0%, 5%, 10%, 15%, 20%, 25%, 30%로 치환하여 그때의 압축, 휨, 인장강도를 측정하였다. 그 결과 하수 슬러지의 증가에 따라 강도 감소를 보였으나, 일반 경량콘크리트 제조 또는 단열용 콘크리트 블록 제조에 사용이 가능하다고 사료된다. 그러므로 앞으로 건조수축, 크리이프 특성 및 내구성에 관한 연구가 더욱 심도 있게 이루어져야 폐자원인 하수 슬러지를 이용한 건자재의 개발이 가능하리라 판단된다. In this study, the polymer concrete was produced by using the lightweight aggregate that had been manufactured using the sewage sludge and its physical properties were experimentally examined. Experimental results show that when the portion of sewage sludge lightweight aggregate in the fine aggregate increases, slump values decreases. Also, the compressive, the flexural and the tensile strengths decrease when the portion of sewage sludge lightweight aggregate increases. Although its strengths decreases, the sewage sludge lightweight fine aggregates is thought to be used for construction materials.

저자들은 1996년 7월에 강원도 춘천지역에서 농사업을 하는 60세 남자의 좌측 안결막에서 총 10마리의 유백색 선충을 적출하였다. 적출된 충체를 형태학적으로 관찰한 결과 Thelazia callipaeda Railliet et Henry, 1910으로 동정하였으며, 그 성적은 다음과 같다. 관찰된 유백색의 충체는 암놈 7마리, 숫놈 3마리였으며 충체의 크기는 암놈 11.91∼12.77×0.25∼0.26㎜, 숫놈 8.83∼9.32×0.24∼0.25㎜ 였다. 암놈과 숫놈의 구강 깊이는 각각 0.023∼0.026, 0.022∼0.023㎜이고, 충체전단에서 식도-장 접합부까지의 길이는 각각 0.58∼0.60, 0.56∼0.58㎜이었다. 표피소극의 배열은 전단부위에서 ㎜당 260∼290열이고 중앙부위에서 ㎜당 203∼207열 정도의 갯수가 관찰되었다. 그리고 암놈의 자궁내에는 coil상의 성숙된 유충이 관찰되었고 숫놈의 배설강구 전방의 유두수는 8쌍이었다. 이상과 같이 암수 충체에 대한 형태특징을 분석한 결과 Thelazia callipaeda로 동정되었다. The authors presented the human Thelaziasis case in Korea, with the review of the literatures. The patient was 60-year-old farmer who had lived in Chunchoun since birth. He complained lacrimation and foreign body sensation of the left eye. Total 10 worms, appeared to be slender milky-white nematodes, were extracted from the left upper conjuctival sac by authors. Micrograph morphological features are as follows: Three male worms are 8.83∼9.32㎜ in length, 0.24∼0.25㎜ in width, 259∼263 cuticular striations per mm, and showing cloaca with spicules. seven female worms are 11.91∼12.77㎜ in length, 0.25∼0.26㎜ in width, 259∼289 cuticular striations per mm, and vulva opening locating anterior to esophago-intestinal junction. From the above findings, these nematodes were confirmed as Thelazia callipaeda Railliet and Henry, 1910.
