      • Prednislolne이 골조직에 미치는 영향에 관한 형태학적 연구

        송혜정,김무강,김원식,이영호 충남대학교 의과대학 지역사회의학연구소 1988 충남의대잡지 Vol.15 No.1

        To study the effects of corticosteroids to the bone tissues, author grouped young(3 weeks affter birth) and adult ICR mouse by dosage, injected intramusculaily prednisolone, a series of corticosteroids, to posterior leg during 6 weeks per day, obtained femurs and tibias, measured the lengths of tibias and femurs. The portions of the distal end of tibial crests were cross-sectioned, general H-E stain was perpormed. The adjacent distal portions of femoral neck were sectioned longitudinally, observed endosteal surface by scanning electron micrscope The results were followings: 1. The adult group injected by large dosage (0.56mg/100g body weight/day) and the young group injected by small dosage(0.14mg/100g body weight/day) from 3 weeks after birth were significantly shorter than the normal group according to statistics. And the adult group injected by small dosage (0.14mg/100g body weight/day) was not different from normal group according to statistics. 2. In the light microscopic sutdy, the adult group injected by large dosage decreased in bone mass of compact bone severely, the adult group injected by small dosage changed a little grade. The young group injected by small dosage from 3 weeks after birth was not severe in bone change, but bone thickness decreased. 3. In the scanning elctron microscopic study, the adult group injected by large dosage and the young group iniected by small dosage from 3 weeks after birth decreased in trabeculae. The trabeculae of the adult group injected by small dosage were decreased slightly. 4. Integrating above all, the changes by prednisolone injection osteoporosis, of young period were more severe than those of adult, too.

        미세유화약물송달시스템을 이용한 로바스타틴의 생체이용률 향상

        윤복영,강복기,정상영,이영원,이시범,황성주,육순홍,강길선,이해방,조선행 한국약제학회 2002 Journal of Pharmaceutical Investigation Vol.32 No.4

        A self-microemulsifying drug delivery system (SMEDDS) was developed to increase the dissolution rate, solubility, and ultimately bioavailability of a poorly water soluble drug, lovastatin. SMEDDS was the mixtures of oils, surfactants, and cosurfactants, which emulsify under conditions of gentle agitation, similar to those which would be encountered in the gastro-intestinal (GI) tract. Various types of self-emulsifying formulations were prepared using four types of oil (Capryol 90, Lauroglycol 90, Labrafil M 1944 CS and Labrafil M 2125), two surfactants (Cremophor EL and Tween 80), and three cosurfactants (Carbitol, PEG 400 and propylene glycol). The efficiency of emulsification was studied using a laser diffraction size analyzer to determine particle size distributions of the resultant emulsions. Optimized formulations selected for bioavailability assessment were Carpryol 90 (40%), Cremophor EL (30%) and Carbitol (30%). SMEDDS containing lovastatin (20 mg and 5 mg) were compared to a conventional lovastatin tablet (Mevacor^? , 20 mg/tab) by the oral administration as prefilled hard gelatin capsules to fasted beagle dogs for in vivo study. The area under the serum concentration-time curve from time zero to the last measured time in serum, AUC_0→24h, was significantly greater in SMEDDS, suggesting that bioavailability increase 130% and 192% by the SMEDDS, respectively. The self-emulsifying formulations of lovastatin afforded the improvement in absolute oral bioavailability relative to previous data of lovastatin tablet formulation. These data indicate the utility of dispersed self-emulsifying formulations for the oral delivery of lovastatin and potentially other poorly absorbed drugs.

        기분 장애 환자에서 나타나는 불특정 CAG 삼핵산 반복서열의 확장

        손성은,임신원,이소영,황혜진,진동규,박정의,김도관,김이영 대한신경정신의학회 2000 신경정신의학 Vol.39 No.2

        연구목적: 기분장애는 그 원인과 발생기전은 아직 밝혀져 있지 않고 있지만, 과거부터 유전적 요인이 질병의 발생과 중요한 연관성을 가지고 있다고 알려져 있다. 특히 양극성 정동장애는 가족력이 있는 경우에 발병될 가능성이 높고, 같은 가족 내에서 발생했을 때 세대가 내려감에 따라서 발병시기가 점차 빨라지며 증세가 심해지는 경향이 있어서 그 유전적 배경에 대해 많은 의문이 있어 왔다. 연구자들은 다양한 증상의 기분장애 환자들의 DNA에서 불특정 CAG 삼핵산 반복(trinucleotide repeat. TNR) 정도를 분석함으로써 TNR 확장이 기분장애의 유전과 관련되는지 살펴보았다. 방법: 환자 군은 DSM-Ⅲ-R 진단기준에 의거하여 양극성 정동장애(N=55), 주요우울장애(N=67) 환자들을 선발하였다. 정상인(N=89)은 정신과적 병력이 없고 다면성 인성검사상 정상의 profile을 나타내는 병원 종사자, 학생 및 건강의학센타 방문자들 중 선발하였다. TNR의 확장은 genomic DNA를 순수분리한 후, (CTG)₁□의 oligonucleotide를 □-□□P-ATP로 방사선 표지하여 반복서열 확장 탐지법(repeat expansion detection)으로 측정하였다. 집단간의 비교를 위해 Mann-Whitney U 검증을 실시하였다. 결과: DNA에서 관찰되는 불특정 CAG 삼핵산 반복 길이의 평균은 양극성 정동장애에서 169.8bp(S.D=58.6), 주요우울장애에서 167.5bp(S.D=63.9)로서 대조군 178.7bp(S.D=56.5)과 비교하였을 때 유의미한 차이는 관찰되지 않았다. 각각의 환자군을 가족력이 있는 군과 없는 환자군으로 나누어 대조군과 비교하였을 때도 유의미한 차이는 관찰되지 않았다. 결론: 불특정 CAG 삼핵산 반복서열 확장이 양극성 정동장애 환자와 주요우울장애 환자들의 유전 양식에 영향을 미친다는 가설을 뒷받침하지 않는다. Objectives: The genetic facotrs have been suggested for the etiology of mood disorders but the mode of inheritance is complex. Increased severity and an earlier onset of the bipolar and major depressive disorder over generations within families(Anticipation) were reported. In order to test the hypothesis that trinucleotide repeat expansions underlie the genetic basis of Bipolar and major depressive disorders, we have analyzed the extent of CAG reapeats in genomic DNA from mood disorder patients. Methods: 55 bipolar disorder, 67 major depressive disorder patients were recruited accord-ing to the DSM-Ⅲ-R criteria. 89 normal controls were recruited from the medical personnel, students and the visitors to the health services center who had no history of psychiatric illness and show normal profile of MMPI. The genomic DNA of patients and controls was analyzed by use of the (CTG)□ oligonucleotide and the repeat expansion detection(RED) method. The Mann-Whitney U test was used to compare the distribution of the number of CAG repeats among the groups. Results: when the bipolar disorder, major depressive disorder patients were compared with the control group, no significant differences were observed. Conclusions: Our results do not support the hypothesis that expanding CAG repeats are causing the observed genetic anticipation in bipolar disorders and major depressive disorders.

        Effect of DREAMMO<SUP>®</SUP> Scalp Lotion on Hair Growth Promotion in an Alopecia Model of C57BL/6 Mice

        Seung Ho Lee,Hwa Jeung Lee,In Jeoung Baek,Jung Min Yon,Sang Yoon Nam,Beom Jun Lee,Young Won Yun,Yun-Bae Kim,Seock Yeon Hwang,Jin Tae Hong 한국실험동물학회 2006 Laboratory Animal Research Vol.22 No.1

        Scalp hair loss has increased recently in young-aged people as well as middle-aged people, and although there are no serious in health problems, scalp hair loss may significantly affect a variety of psychological and social experiences and the individual's quality of life. DREAMMO scalp lotion is composed of several plant extracts which are known to be used as oriental medicine to prevent hair loss or promote hair growth in alopecia. This study was carried out to investigate the effect of DREAMMO scalp lotion on hair growth in an alopecia model of C57BL/6 mice. Mice were divided into three experimental groups including control, DREAMMO scalp lotion and 3% Minoxidil (MXD). The test compounds were topically treated with 0.2 ㎖ per mouse per day for 4 weeks. The hair growth was determined photographically and histologically in an alopecia model of C57BL/6 mice. After 3-4 weeks, DREAMMO scalp lotion significantly increased hair growth compared to the controls in the dorsal skin of C57BL/6 mice. DREAMMO scalp lotion also promoted the elongation of hair follicles than the controls. These results suggest that DREAMMO scalp lotion has a hair growth activity and can be useful for the treatment of alopecia.

        흰쥐에서 심정지후 Pentoxifylline이 뇌의 허혈-재관류 손상에 미치는 효과

        정시경,김영민,오동렬,최경호,박승현,이운정,박규남,유은영,이원재,김세경 大韓應急醫學會 1999 대한응급의학회지 Vol.10 No.2

        Background: Two major events occurring in the cerebral hemodynamics after successful resuscitation from cardiac arrest are reactive hyperemia and postischemic hypoperfusion. In this study, we examined the effect of Pentoxifylline(PTX) on the rat brain following cardiac arrest. Methods: Fourteen rats were anesthetized and artificially ventilated. Cardiac arrest was produced by chest compression and clamping of tracheal tube for 3 minutes in ketamine anesthetized rats. Circulation was restored by standard cardiopulmonary resuscitation methods. In 7 rats, PTX 10mg/kg was infused at 10min after cardiac arrest(PTX group). In the other 7 rats, same amount of normal saline was infused(control group). Results: In both groups, hemodynamic variables, neurologic deficit(ND) score and histopathologic findings of hippocampal CA1 neurons were observed. Hemodynamic variables and ND score were not significantly different between two groups. Delayed ischemic neurons of hippocampal CA1 were decreased in PTX group(2.2±2.4%) compared with control group(9.1±1.2%). Conclusions: We conclude that PTX prevented development of delayed ischemic neurons in hippocampal CA1 after cardiac arrest. PTX may be useful in emergency situations following cardiac arrest.

        반복적인 경련을 동반한 아이소니아지드(Isoniazid) 중독환자의 치험 1례

        이환,오동렬,정시경,김영민,이운정,김세경,이원재,최경호 大韓應急醫學會 1999 대한응급의학회지 Vol.10 No.2

        Isoniazid(Isonicotinic acid hydrazide) is an antimicrobial drug used since 1952 as a first line agent for the prophylaxis and treatment of tuberculosis. Isoniazid is well known for problems in population having a high prevalence of isoniazid use for prophylaxis or treatment of tuberculosis. But intentional or accidental isoniazid overdose is uncommon. The ingestion of toxic amounts of isoniazid causes recurrent seizures, profound metabolic acidosis, coma and even death. In adults, toxicity can occur with the acute ingestion of as little as 1.5g of isoniazid. Doses larger than 30mg per kg often produce seizures. When ingested in amounts of 80-150mg per kg or more, isoniazid can be rapid fatal. 40-year-old woman having previous pulmonary tuberculosis ingested 7gram of isoniazid(140mg/kg) to attempt suicide approximately 30 minutes prior to visit to our emergency medical center. She had recurrent generalized tonicclonic seizures and metabolic acidosis. We report one patient treated with pyridoxine, which was equivalent to the amount of isoniazid ingested and administered as a intravenous dose and oral dose

        응급실 내원 환자의 만족도 평가 및 관련 요인에 대한 연구

        서강석,감신,박정배,이정헌,김종근,윤영국,곽경숙,이원기,우석정 大韓應急醫學會 1998 대한응급의학회지 Vol.9 No.4

        Background: To examine the influencing factors on patients' satisfaction in the emergency department(ED) for quality assurance. Methods: Patients who visited to the ED were prospectively investigated from November 1 to December 31, 1997. Authors developed questionnaire to investigate influencing factors on patients' satisfaction. A Chi-square test and LISREL 7.0 were applied for statistical analysis. Results: Patients' satisfaction was significantly related to physical environment variables, accessibility variables, kindness of hospital personnel variables, and patient's trust for doctors variables. In path analysis, willingness for revisit was influenced by patients' satisfation, accessibility, physical environment, patients' trust for doctors in order, and willingness for recommendation was influenced by accessibility, patients' satisfaction, and kindness of hospital personnel in order. Conclusions: The influencing factors on patients' satisfaction are physical environment, accessibility, kindness of hospital personnel, and patient's trust for doctors. Willingness for revisit and willingness for recommendation are influenced by patients' satisfation. In spite of some limitations, the results of this study can be used as a baseline information for exploring the influencing factors on patients' satisfaction. Further comprehensive research efforts should be made on the study of patients' satisfactoin in the ED.

        응급센터에서 기관내 삽관을 시행하지 않은 호흡곤란 환자의 동맥혈 이산화탄소분압과 호기말 이산화탄소분압의 연관성분석

        김형국,박승현,오동렬,박규남,이원재,황두영,최승필,이운정,정시경,김세경 大韓應急醫學會 1998 대한응급의학회지 Vol.9 No.4

        Background: The end-tidal carbon dioxide tension(ETCO₂) is defined as a partial pressure of carbon dioxide at the end of an exhaled breath. The purpose of this study is to determine the correlation between ETCO₂and arterial carbon dioxide tension(PaO₂) in nonintubated patients with respiratory distress in emergency department(ED). Methods: A prospective non-blind study was performed in ED of our university hospitals. Participants included all nonintubated adult patients with respiratory distress requiring arterial blood gas analysis. ETCO₂was measured with a capnography monitor during tidal volume breathing. ETCO₂were recoreded at the time of arterial blood gas sampling. The correlation between ETCO₂and PaCO₂was analyzed in all patients and in subgroups by simple linear regression. Results: Sixty patients were enrolled. In all patients, ETCO₂was 5.72mmHg lower than PaCO₂and correlated well with PaCO₂(r²=0.716). ETCO₂correlated best with PaCO₂in patients who were either acidotic or non-smoking. Conclusion: ETCO₂correlate well with PaCO₂in nonintubated patients with respiratory distress in ED. ETCO₂may be sufficient to reflect PaCO₂in selected patients and obviate the need for repeat arterial blood gas determination.
