To evaluate the safety and efficacy of Pd withdrawal followed by recombinant alpha- Interferon 2b therapy. Nine patients were given a single daily subcutaneous injection of ^α-Interferon at a dose of 3 x 10 exp(6) units/day for first weeks and thrice weekly for next 15 weeks (maintenance) after pd tappered over 6 weeks. To evaluate the efficacy of therapy, we measured serum aminotransferase activities monthly during and after therapy, and also measured serm HBsAg, HBeAg and DNA probe before and after therapy. To evaluate the safety of therapy, all patients checked peripheral blood WBC, Hemoglobin, Platelet, BUN and Creatinine. The results were as follows : 1. In control group, the normalization of s-AST & ALT level, negative seroconversion of DNA probe & HBeAg were observed in 1/12(8%) & 7/10(17%), 0/10(0%) & 0/12(0%) at 6 months later, and maintained response in 1/11(9%) & 1/11(9%), 2/9(22%) & 2/11(18%) until 1 years later. 2. In treatment group, Serum AST and ALT returned to normal in 8/9 & 8/9 cases (89%) after 1 montns Tx. (mean serum AST : 33±8, ALT : 34±12 IU/ml) and maintained to normal response in 5/9(56%) & 6/9 cases(67%)after 6 months Tx. (mean s-AST : 55±43, ALT : 66±84 IU/ml), 3/9(33%) & 4/9 cases(44%) after 1 years Tx. It was statistically significant reponse except s-AST of after 1 years Tx. 3. In treatment group, s- HBeAg returned to normal in 3/9 cases(33%) after 1 months Tx., and maintained to normal response in 1/7 & 1/4 cases among follow up patients in after 6 & 12 months Tx. Serm DNA probe level were observed significantly negative seroconversion in 8/9 cases(89%) after 1 months Tx. (p<0.003), and maintained to negative response in 2/6 & 1/3 cases after 6 & 12 months Tx. 4. Serum AST, ALT, HBeAg and DNA probe were not significantly correlated with therapeutic response in relation to histologic diagnosis. 5. Fever and myalgia were noted in 9(100%) & 6(67%) cases. Headache, mild hair loss, anorexia, nausea, facial flushing & diarrhea were noted in few cases. Peripheral WBC(3cases) & platelet counts(3cases) were decreased transiently. This study shows that Pd withdrawal followed by recombinant alpha Interferon 2b therapy may be safe and effective in decrease the level of s-DNA probe, transaminase activity, loss of HBeAg and less adverse effect of clinical and hematologic examinations in patients with CAH type B. But it was necessary for study with large number of patients, more prolonged follow up duration and more strict control study.

용접공에서 혈중 중금속 농도와 혈장중 Malondialdehyde, α-tocopherol 및 적혈구내 Superoxide Dismutase 활성도에 관한 연구

이원진,장성훈,황천현,천병철,김해준 大韓産業醫學會 1998 대한직업환경의학회지 Vol.10 No.2

We investigated the association between the oxidative stress and the concentration of heavy metals in blood among welders. The study subjects were male manual CO₂welders(N=127) exposed to several heavy metals. The age distribution was from 20 to 63(GM=33.7) and the geometric mean(GM) of work duration was 4.2 years. We analyze the level of blood lead, cadmium, manganese and chromium which was related with the oxidative stress in the animal studies. Blood selenuim, plasma malondialdehyde(MDA), plasma α-tocopherol and erythrocyte superoxide dismutase(SOD) were analyzed as biological markers of the oxidative stress. The results of univariate analysis showed that the plasma MDA was significantly correlated with α-tocopherol(r=0.327) and blood selenium(r=0.313) concentration. But we could not find out any relationship between the erythrocyte SOD activities and those metal concentrations. Neither smoking nor alcohol consumption was related to the level of heavy metals and the oxidative stress biomarkers. As the results of multiple regression analysis with stepwise selection method, 1) the change of MDA level were dependent with the level of α-tocopherol and blood selenium concentration(R²=19.7), 2) the plasma α-tocopherol level was dependant with MDA and blood chromium concentration(R²=15.6), 3) in case of erythrocyte SOD activity, only the duration of work was significantly selected.

민병근,이창화,안준호,천두욱,김헌수 울산대학교 의과대학 1994 울산의대학술지 Vol.3 No.2

The application of neuroleptics to schizophrenic and other psychotic patients in the early 1950's led to the therapeutic revolution into the psychiatry, on the other hand neuroleptic-related adverse effects did frequently occur. The authors experienced 2 cases of rabbit syndrome producing by rare complication of neuroleptic medication. Two cases were examined for the rabbit syndrome by the description of Villeneuve(1972) and Sovner and DiMascio(1977). The reciprocal coordination test and the finger-tapping technique to worsen the symptoms also were applied to two patients. The authors emphasized two issues of rabbit syndrome as follows. First, though the literature search showed that the majority of patients presented with rabbit syndrome which is usually seen after a prolonged exposure to neuroleptic medication with the more potency in the middle or elderly aged are over 45 years old, we suggest that this syndrome might be linked to the younger age factor and the low potency thioridazine in our patient. Second, the rabbit syndrome is in the importance of the clinical practice because of being readily reversible with antiparkinsonian agents or anticholinergic drugs. In addition, recognizing this condition and differentiating it from tardive dyskinesia helps in the choice of the proper treatment of orofacial disorders following neuroleptic medication for the long time.

전제천,김치홍,정의영,이창훈,김병균 한국어류학회 2002 韓國魚類學會誌 Vol.14 No.3

본 연구는 돌 가자미(Kareius bicoloratus)의 난발생에 미치는 수온과 염분의 영향을 알아보지 위하여 수행되었다. 5단계의 수온 조건 (7, 10, 13, 16 및 19℃) 및 5단계의 염분 조건(25, 30, 35, 40psu 및 현장해수 염분 : 33.6psu)에서 수정란을 발생시켜 발생 속도와 부화율 측정하였다. 수정란의 발생속도는 수온이 높을수록 빨랐으며, 수온(T: ℃)과 각 발생 단계별 소요시간(h:hour) 사이의 관계를 직선 함수에 회귀시켰을 때 각 발생단계별 관계식은 다음과 같다. 8세포기 : 1/h = 0.01441T - 0.02728(r^(2) = 0.998) 낭배기 : 1/h = 0.00269T - 0.00319(r^(2) = 0.997) 안포형성기 : 1/h = 0.00171T - 0.00053(r^(2) = 0.998) 심장형성기 : 1/h = 0.00121T - 0.00018(r^(2) = 0.995) 부화기 : 1/h = 0.00101T - 0.00266)(r^(2) = 0.998) 이상의 관계식으로부터 추정된 돌 가자미의 난 발생이 개시되는 생물학적 영도는 1.3℃이었다. 8세포기, 낭배기, 안포형성기. 심장형성기 및 부화기까지의 적산수온은 각각 72.9, 356.7, 525.8, 735.2 및 1156.7℃로 계산되었다. 수온은 부화율에 큰 영향을 미치는 것으로 나타났다(p<0.001). 부화율이 수온이 증가할수록 감소하였으며, 7℃일 때 부화율이 62.0%로 가장 높았다. 수온이 16℃ 이상일 때 기형어의 출현율이 증가하였다(p<0.05). 염분 또는 부화율에 큰 영향을 미치고 있었다(p<0.001). 염분에 따른 부화율은 자연해수의 염분인 33.6psu에서 54.1%로 가장 높았고, 이보다 낮거나 높은 경우에는 부화율이 감소하였다. 특히, 염분이 30psu 미만으로 감소할 경우 기형어의 출현율 증가하였다(p<0.04). 돌 가자미의 난 발생 및 정상적인 부화를 위한 조건은 산란시기의 수온과 염분에 가까울수로고 좋은 것으로 판단된다. This study was conducted to determine the influences of water temperature and salinity on the embryonic development of the stone flounder, Kareius bicoloratus as a part of research on the artificial seedling production of the fish. Embryos were incubated under five different temperatures (7, 10, 13, 16 and 19℃) and five different salinities (25, 30, 35, 40 psu and the ambient salinity: 33.6 psu) until they hatched. The required times for embryonic development decreased with increase of water temperature. The relationships between the water temperature (T: ℃) and required times (h: hour) for the embryo to attain each develop-mental stage were obtained by linear regressions as follows; 8-cell stage : l/h = 0.01441T-0.02728 (r² = 0.998) 50%-epiboly stage : Uh = 0.00269T-0.00319 (r² = 0.997) Optic vesicle formation stage : l/h = 0.00171T-0.00053 (r² = 0.998) Heart formation stage : l/h = 0.00121T-0.00018 (r² = 0.995) Hatching stage : l/h = 0.00101T-0.00266 (r²= 0.998) From these equations, the biological minimum temperature for embryonic development of K. bicoloratus was estimated to be 1.3℃. Cumulative water temperatures to reach 8-cell stage, 50%-epiboly stage, optic vesicle formation stage, hearth formation stage, and hatching stage were 72.9, 356.7, 525.8, 735.2, and 1,156.7℃, respectively. Water temperature affected significantly the hatching rate (p< 0.001). The hatching rate decreased with increase of water temperature. The highest hatching rate was 62.0% at 7℃. When the water temperature was higher than 16℃, the proportion of abnormal larvae increased (p < 0.05). Salinity also affected significantly the hatching rate (p< 0.001). The highest hatching rate was 54.1% at the salinity (33.6 psu) of ambient seawater. When the salinity was lower than 30 psu, the proportion of abnormal larvae increased ip < 0.05).

大學 Sports로서의 Tennis에 關한 考察 : 慶北大學校 學生을 中心으로 centered on the students in K.N.U.

金柄斗,李淳川 慶北大學校 1978 論文集 Vol.25-26 No.-

The result of Survey and analysis which are studied on tennis as college sports is as the folloiwing. 1) The students who take part in playing tennis as extra activity are almost low grade students such as freshmen and sophomore. Their career of playing tennis is ranging from a few month to one or two years, and they have no experience of taking part in official match. This survey show that tennis is the sports which every one enjoys including ladies and gentlemen. 2) when we see the motivation of their playing tennis, they play it not only as a recreation, and because it is suitable for their hobbies and aptitudes, but also they have obvious purpose of making friendes by playing tennis. They enjoy usually playing tennis by themselves or with their friend's couch, so it is difficult for them to learn playing tennis. 3) As enjoying tennis, this survey shows that it gives comfortable mind, and no obstruct effects physically and economically. 4) The time of playing tennis is usually an hour a day. The students who play tennis every three days or one a week spend two hours enjoying it. 5) Tennis players spend their everyday life satisfactorily, Tennis is very good to keep one's Health because it is not excessive sports phyically. 6) The expense which is needed in playing tennis is generally from their Sundries, They spend from five hundred won to threethousand won in a month. 7) Their parents pay a little or no attenion to the students' playing tennis even though they can discern everything and act for themselves. 8) Most of the students who are enjoying playying tennis are supposed to continue tennis actvity because it is popular and suitable sports for their health. For some students, their is a little possibility to stop playing tennis because sports facility such as tennis court, racket, tennis ball is not enough yet.
