        Background : Arterial blood gas analysis is the most comon exam in intensive care unit. In this study, the frequency of blood gas analysis and the amount of blood loss after Blood Gas Analysis in Intensive Care Unit were observed. Methods : From November 1999 to February 2000, 115 patients admitted to intensive care unit at Soonchunhyang university Kumi hospital were studied prospectively for the frequency of blood gas analysis and the amount of blood loss after blood gas analysis in Intensive Care Unit. Results : The mean value of frequency of blood gas analysis was 6.41±6.49 and the mean value of amount of blood loss after blood gas analysis was 0.78ml. This was lower than that of other foreign reports. The patients with ventilator therapy above 24 hours showed higher frequency of blood gas analysis than that of not applied ventilator patients. Pulse oxymetry was applied to all patients and the frequency of blood gas analysis was decreased due to the use of strict pulse oxymetry. Conclusion : Doctors and nurses in intensive care unit keep in mind that adequate blood sampling is needed for the decrease of blood loss. Education and protocol for the decrease of blood loss after arterial blood gas analysis may be necessary.

      • 대학생 흡연자의 금연경험에 따른 건강신념차이

        구정일,김민정,김동희,백정희,안현실,은가희,우혜령,이명희,이수현,김수지 이화여자대학교 간호과학대학 2003 이화간호학회지 Vol.- No.37

        It has been generally known that smoking is one of the worst factor increasing disease and mortality in human health since in 1950's and nowadays. But regardless of various proofs about social or economical problems due to smoking, current smoking rate has not been decreased in our country. Until now, most of tobacco use and its addiction researches have been focused on the adolescent or adult women smokers not on the university students. Therefore, the purpose of this study was to investigate smoking cessation of university smokers and analyze the health belief-perceived sensitivity, severity, benefits and barriers- difference, then to provide basic data for effective smoking cessation strategy for university smokers. The subjects were comprised of 181 university smokers from 15 universities in Seoul. The data were collected by structured questionaires. The questionaires were designed to measure general characteristics, smoking cessation and health belief, based on Ahn(2003)'s result on the Study of Smoking attitude, Behavior and Smoking Cessation of Adult Male and Lee(1987)'s result on Relationships Between the Health Belief Model and Smoking Habits. The data were collected from May 5 to 16. The collected data were analyzed by SPSS program. The actual number, percentiles, means, standard deviation, t-test and ANOVA were done. The result of this study were as follows; 1. The general characteristics of the subjects of this study The range of age was from 18 to 34 and the averaging age was 23. The subjects of this study were 141 males and 40 females. The religions were Christianity 25.4%(46), Buddhism 12.7%(23), Catholic 23.2%(42), no religion 37.0%(67). The residential forms were living with family 59.1%(107), cooking food for oneself 28.7%(52), dormitory 5.0%(9), boarding house 1.7%(3). Smoking starting age were university 43.1 %(78), high school 29.8%(54), middle school 14.9%(27), in the army 6.1 %(11), elementary school 1.1 %(2). 2. The smoking cessation of the subjects 80% of current smokers showed quitting smoking decision and 20% have not tried. The frequency of quitting smoking decision were from 1 to above 8 and mean was 3.06. As for smoking cessation plan, 54.7%(99) current smokers answered yes, 3.9%(7) said no, 35.4%(64) had no idea and 6.1 %(11) didn't answer. As for the reason of never quitting smoking decision, 71.42%(25 among total 35) have no need to quit smoking and the others said difficulty of smoking cessation. As for the main reason of smoking cessation decision, 54.7%(99) answered for the health, 7.2%(13) family advice, 15.5%(28) girl/boy friend's advice, 1.7%(3) to save money. As for the reason to fail smoking cessation, 56.7%(68) were will-lack, 17.5%(21) stress, 15%(18) smoking mood, 10%(12) withdrawl symptom. As for the smoking cessation method, 85.0%(125) were oneself-will, 2.7%(4) way acquired by mass-media, 2%(3) doctor's prescription, 2%(3) religion's help, 0.7%(1) smoking cessation school. As for the difficulty in smoking cessation, 42.2%(62) were drinking meeting, 23.1 %(34) no alternative of stress release, 12.2%(18) withdrawl symptom, 11.6%(17) having nothing to do, 7.5%(11) friend's encouragement. As for the most difficult cigarette to quit, 67.8%(99) were all-day smoking except the first smoking in the morning, 32.2%(47) the first smoking in the morning. 3. Health belief as for general characteristics Gender - The total point in benefits showed higher in male(28.5177) than female(26.6750). There was significant difference(t=.778, p<.05). The total point in health belief showed higher in male (105.8298) than female(l00.5000). So there was significant difference(t=.345, p<.05). Age - There was significant difference in benefits between age(10's-25.83, 20's-28.39, 30's-32.00)(F=3.73, p<.05). Smoking starting age - There was significant difference in total point of sensitivity and health belief(sensitivity F=4.00, p<.Ol, health belief F=2.843, p<.05). As for sensitivity, subjects who started smoking in the army showed the highest(33.36) and ones in high school showed the lowest(26.96). The total point in health belief showed the highest in elementary school(l19.00) and the lowest in high school(100.98). 4. Health belief as for smoking cessation There was significant difference in health belief as for smoking cessation(t=0.189, p=0.OO2). Sensitivity point showed higher in smoking quitting trial smokers(29.2) than non-trial smoker (26.9). Severity point showed higher in trial smokers (30.7) than non-trial smokers(28.9). Benefit point showed higher in trial smokers(28.6) than non-trial smokers(26.2). There was no significant difference in barriers point.

        This study was performed to investigate the effects of peking-duck extracts added with medicinal herbs(DJ) on the intoxication of heavy metals (Hg, Pb, Cd, As) in rats. Sprague-Dawley rats weighing 150±15g, were randomly assigned to 5 groups: basal diet only in normal control group(NCG); basal diet and heavy metals without DJ injection in heavy metal control group(HMC); basal diet, heavy metals and DJ(3㎎/㎖) injection in heavy metal low duck juice group(HMLD), basal diet, heavy metals and DJ(30㎎/㎖) injection in heavy metal middle duck juice group(HMMlD); basal diet, heavy metal and DJ(300㎎/㎖) injection in heavy metal high duck juice group(HMHD). Hg and As was injected by 50ppm and Cd and Pb by 25ppm for 17days. Also DJ oral feeding was conducted for 28days. The result of this study were as follows: Food intake and body weight gain in heavy metal administered groups were lower than those of NCG. Liver, kidney and testis weights were not significantly different among 5 groups. GOT, GPT and BUN activities were significantly reduced in DJ treated groups as compared to HMC. DJ showed the suppressing effect on the accumulation of Hg, Pb and Cd in serum, liver and kidney. Fecal Hg and Cd excretions increased with DJ feeding. The results suggested that DJ may have some protective effects on Hg, Cd and Pb intoxication by reducing the accumulation m tissues and increasing excretion. This study also showed the effective way of using duck-extract and its application to the oriental medicine.

        Elevated extracellular calcium ions promote proliferation and migration of mesenchymal stem cells via increasing osteopontin expression

        Lee, Mi Nam,Hwang, Hee-Su,Oh, Sin-Hye,Roshanzadeh, Amir,Kim, Jung-Woo,Song, Ju Han,Kim, Eung-Sam,Koh, Jeong-Tae Nature Publishing Group UK 2018 Experimental and molecular medicine Vol.50 No.11

        <▼1><P>Supplementation of mesenchymal stem cells (MSCs) at sites of bone resorption is required for bone homeostasis because of the non-proliferation and short lifespan properties of the osteoblasts. Calcium ions (Ca<SUP>2+</SUP>) are released from the bone surfaces during osteoclast-mediated bone resorption. However, how elevated extracellular Ca<SUP>2+</SUP> concentrations would alter MSCs behavior in the proximal sites of bone resorption is largely unknown. In this study, we investigated the effect of extracellular Ca<SUP>2+</SUP> on MSCs phenotype depending on Ca<SUP>2+</SUP> concentrations. We found that the elevated extracellular Ca<SUP>2+</SUP> promoted cell proliferation and matrix mineralization of MSCs. In addition, MSCs induced the expression and secretion of osteopontin (OPN), which enhanced MSCs migration under the elevated extracellular Ca<SUP>2+</SUP> conditions. We developed in vitro osteoclast-mediated bone resorption conditions using mouse calvaria bone slices and demonstrated Ca<SUP>2+</SUP> is released from bone resorption surfaces. We also showed that the MSCs phenotype, including cell proliferation and migration, changed when the cells were treated with a bone resorption-conditioned medium. These findings suggest that the dynamic changes in Ca<SUP>2+</SUP> concentrations in the microenvironments of bone remodeling surfaces modulate MSCs phenotype and thereby contribute to bone regeneration.</P></▼1><▼2><P><B>Bone formation: released calcium could stimulate stem cells</B></P><P>Studies with mouse cells and bone samples indicate how calcium ions released during the normal turnover of bone promote the supplementation of stem cells needed to make new bone during routine “remodeling” and regeneration after injury. Our bones are degraded and remodeled continuously, requiring the controlled supplement of stem cells that create bone-forming cells called osteoblasts. Jeong-Tae Koh and colleagues at Chonnam National University, Gwangju, South Korea, exposed the relevant stem cells to increased concentrations of external calcium ions. This promoted cell proliferation and migration that allow the cells to support new bone formation. The research suggests this effect on stem cells may be achieved by calcium ions released directly from bone as it is naturally degraded. The findings may help researchers develop new ways to encourage bone regeneration after injury and surgery.</P></▼2>

      • Putrescine처리가 절화 카네이션 'Desio'의 화판 노화에 미치는 영향 : Ethylene 발생, ACC synthase, EFE 활성변화 Change of ethylene production and ACC synthase and EFE activities

        이인국,권혜정,손기철 建國大學校 附設 農業資源開發硏究所 1993 農資源開發論集 Vol.18 No.-

        절화 카네이션 'Desio' 품종의 화판 노화시 발생되는 에칠렌의 발생량은 계절에 따라 달라 2월경 채화된 것은 약 70nl/g·FW/hr를 나타내었으나, 7월에 채화된 것은 4.3nl/g·FW/hr 불과했다. 폴리아민 중 put의 10mM 처리는 EFE의 활성과 에칠렌의 발생을 억제시키고 화판의 노화를 지연시켰으나, 대조구나 put 1Mm의 처리구에 비해 높은 ACC synthase의 활성을 나타내었다. 한편, 1mM put 처리는 ACC synthase의 활성이 억제됨에도 불구하고 에칠렌이 생성되어졌다. 이러한 사실은 기작이 명확치 않으나 put처리가 에칠렌 생합성 과정중 EFE보다 ACC synthase의 활성에 직접적인 영향을 미치는 것을 나타내며, 내생 폴리아민의 농도에 따라 외생 폴리아민의 카네이션 화판의 노화에 미치는 영향이 다름을 나타낸다. Ethylene evolution on the senescence of petals of cut carnation cv. Desio was varied according to the cultural seasons, where 70 ul/g·fw/hr of ethylene was produced in Feb. harvest, but only 4.3 ul/g·fw/hr in July. Despite that 10mM putrescine treatment on the petals inhibited ethylene production and EFE activity, and delayed the senescence, it rapidly stimulated ACC synthase activity over those of control and 1mM putrescine treatment. In addition, ethylene was produced in the 1mM putrescine treatment even though ACC synthase acitiviy was inhibited. This fact indicates that purtrescine has influence on rather EFE than ACC synthase on the biosynthesis of ethylene and the effect of exogenous polyamines on the senescence is varied according to the level of endogenous polamines in the petals of cut carnation.

        A 5-year-old German Shepherd dog(intact male, 27kg) was admitted to the Veterinary Medical Teaching Hospital of Chungnam National University with the history of anorexia and vomiting. On physical examination, he was depressed and had abdominal distention. A complete blood count indicated leukocytosis and anemia. Radiographic findings included a large soft tissue mass in the middle to caudal abdomen and loss of serosal detail. Ultrasonographs showed splenomegaly with mixed ethoic parenchyma, hyperechoic area around the splenic hilus, and loss of venous flow. Computed tomography revealed enlarged spleen with partially enhanced parenchyma. Chronic isolated splenic torsion was diagnosed and splenectomy was performed. Histopathologic examination revealed chronic passive congestion of the spleen. He was recovered normally after surgery without any complications.
