Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

Background: Pulmonary tuberculosis is a great public health problem in Korea. Early detection of Mycobacterium tuberculosis (M. tuberculosis) in clinical samples becomes more and more important in the control of tuberculosis. Recently, molecular methods have been applied to early detection of M. tuberculosis. Methods: To elucidate the effectiveness of nested polymerase chain reaction (PCR) in early diagnosis of pulmonary tuberculosis, we peformed Acid-fast bacilli (AFB) stain, AFB culture, and nested PCR on 84 sputa. Results: 8 (9.5%) specimens were positive by AFB stain, 17 (20.2%) by AFB culture, and 15 (17.9%) by nested PCR. Using AFB culture as standard method, the sensitivity of AFB stain and nested PCR was 47.1% and 82.4%, respectively. The specificity of AFB stain and nested PCR was 100% and 98.5%, respectively. Conclusions: Nested PCR was more sensitive than AFB stain and had shorter processing time(24-48hrs) than AFB culture. So it may be effective to use nested PCR in order to detect M. tuberculosis when AFB smear Is negative.

The Anti-cancer Effect of Oriental Medicine Chung-Ri-Ja-Gam-Tang in the Mouse with Metastatic Lung Cancer. Proceedings of International Symposium on East-West Medicine, Seoul. 231-243, 1999.-The oriental medicine Chung-Ri-Ja-Gam-Tang is an herbal medicine which has been used for pulmonary diseases and known as having immune stimulatory effects. It has been known effective in lung cancer. So we studied the effects and the mechanisms of this herbal medicine it the mouse with metastatic lung cancer. The metastatic lung cancer of the mouse was produced with melnoma cell line(B16BL/6).5×10□/mouse tumor cells were injected intravenously to the CDF1 mouse via tail vein. The mice were divided 4 groups. The first group was treated with 50mg/kg extract of Chung-Ri-Ja-Gam-Tang per oral for 10 days after cancer cell injection, second group treated with saline after cancer cell injection, the third group with medicine without cancer cell, and the last group with saline only. After 10 days treatments some of the mice were scarificed and the lung and spleen was removed. The survival duration, weight change, the number of metastatic cancer nodule of the lung, the NK cell activity, the capacity of cytokines(INF-γ,INF-α,IL-2) production and the proliferation activities of mouse lymphocytes were measured. The surival times of the group 1 mice were longer and the weight loss was less than the group 2 significantly. The number of the metastatic nodule of the lung were decresed in the group 1 than the group 2. The production of INF-γ,was increase in group 2 than group 3 and 4, IL-2 production was increased in group 1 than group 2,3,4 significantly. There was no difference in TNF- α production and proliferation activity of lymphocyte in each group. The NK cell activity was significantly increased in group 1 than group 2,3,4. We conclude that the Chung-Ri-Ja-Gam-Tang has the effect of increasing the NK cell activity of the CDF1 mouse with metastatic lung cancer(B16BL/6). And it is suggested that the increased production of the IL-2 is the mechanisms of enhanced NK cell activity.

Background: The aim of this study was to determine whether the conventional subcostal approach is suitable for emergency pericardiocentesis in patients with cardiac tamponade or impending cardiac tamponade. Methods: This study was a prospective, observational study conducted at the emergency department of a tertiary hospital, Patients who had symptomatic pericardial effusion and who needed emergency pericardiocentesis in the emergency department were included in this study. We measured the epicardium-to-pericardium distance at the subcostal, parasternal, and apical area with two-dimensional echocardiography to determine the appropriate puncture site for pericardiocentesis. An epicardium-to-pericardium distance of more than 1.0 cm was considered as the primary safety factor in determining the Puncture site for pericardiocentesis. The skin-to-pericardium distance was considered as secondary safety factor. Results: Ninety-five consecutive patients(55 males and 40 females; total mean age: 53 year old) with cardiac tamponade or impending cardiac tamponade were enrolled in this study. The puncture site for pericardiocentesis, as determined by echocardiography, was the subcostal area in 43 patients(45%), the apical area in 40 patients(42%), the left parasternal area In 11 patients(12%), and the right parastemal area in one patient(1%). Pericardiocentesis failed in 2 patients(2%) with the subcostal approach and in one patient(1%) with the apical approach. The average epicardium-to-pericardium distance was 31 ±21 mm in patients with the subcostal approach and 21±8 mm in patients with other approaches. There were no differences in the amount of pericardial fluid and in the intraperical pressure among patient groups according to puncture site. There were two procedure related complications: a puncture of the right ventricle with the subcostal approach and a ventricular tachycardia with the apical approach.

한국인 음주자들의 혈청 Gamma Glutamyl Transferase 활성도에 관한 연구

金輝俊,安智榮,金昌世 순천향대학교 1992 논문집 Vol.15 No.2

The enzyme r-glutamyl transpeptidase(GGT) catalyzes the hydrolysis of r-glutamyl peptides such as glutathione and the transfer of their r-glutamyl moieties to amino acids and peptides. Since GGT was discovered in 1950 by Hanes et al., it has been established as useful supportive liver function test in various hepatobiliary diseases. Since Zein et al. found in 1970 that serum GGt activities were markedly increased in chronic alcoholism, even though both transaminase and alkaline phosphatase(ALP) being normal, a number of studies have shown a elvations of GGT in alcoholism and good correlation between GGT and amount of alcohol intake. Recently, it has been suggested that serum GGT activity may have a value as a sereening test for alcoholism. This study was conducted on 459 male adults who were examined periodically for physical checkup at Chunan hospital of Soonchunhyang University College of Medicine in October, 1991, with structural questionaire about their drinking habits. Among 459 male adults serum GGT was determined in 236 healthy men consisted of 40 teetotalers and 196 drinkers assessed by history taking, physical examination, and liver function test. This study was attempted with following objectives : 1) to investigate a correlation between serum GGT activity and amount of alcohol intake(grams of pure ethanol per week) and between serum GGT activity and duration of alcohol intake by years, and 2) to investigate whether increased serum GGT activity reflects amount of alcohol intake and duration. The result obtained are as follows; 1) The means of serum GOT in 40 teetotalers and 196 healthy drinkers were 24.8±6.0 U/L and 25.1±5.3 U/L, respectively. The means of two groups showed no statistically significant difference at p >0.05. 2) The means of serum GPT in 40 teetotalers and 196 healthy drinkers were 23.7±8.2 U/L and 22.5±7.3 U/L, respectively. The means of two groups showed no statistically significant difference at p>0.05. 3) The means of serum GGT in 40 teetotalers and 196 healthy drinkers were 24.3±7.3 U/L and 38.9±20.3 U/L, respectively. The mean of serum GGT in healthy drinkers is higher than the mean of serum GGT in teetotalers. The means of two groups showed statistically significant difference at p<0.05. 4) In 196 healthy drinkers the increase of serum GGT activity was paralleled with increasing alcohol intake. Means of serum GGT activities of 5 groups classified by amount of alcohol intake showed statistically significant difference at p<0.05. But serum GGT activity was increased only in long-standing frinkers over 20 years according to duration of alcohol intake. 5) The probability of being a heavy drinker was increased with increasing serum GGT activity and presumably increased to 60% at 80U/L or more of serum GGT activity. 6) Serum GGT activity showed statistically significant correlation with amount of alcohol intake(r=0.3237) and weak correlation with duration of alcohol intake(r=1.1971).

Where no records are available at a site, a preliminary estimate may be made from relations between floods and catchment characteristics. Anumber of these characteristics were chosen for testing and were measured for those catchments where mean annual flood estimates were available. Although the improvement using extended data in regression of flood estimates on catchment characteristics was small, this may be due to the limitations of the regression model. When an individual short term record is to be extended, more detailed attention can be given; an example is presented of the technique which should be adopted in practice, particularly when a short term record covers a period which is known to be biassed. A method of extending the peaks over a threshold series is presented with a numerical example. The extension of records directly from rainfall by means of a conceptual model is discussed, although the application of such methods is likely to be limited by lack of recording raingauge information. Methods of combining information from various sources are discussed in terms of information from catchment characteristics supplemented by records, but are generally applicable to different sources of information. The application of this technique to estimating the probable maximum flood requires more conservative assumptions about the antecedent condition, storm profile and unit hydrograph. It is suggested that the profile and catchment wetness index at the start of the design duration should be based on the assumption that the estimated maximum rainfall occurs in all durations centered on the storm peak.

2003년 임상검체로부터 분리된 Extended-Spectrum β-Lactamase 생성 Escherichia coli와 Klebsiella pneumoniae의 조사

최영진,김휘준 순천향의학연구소 2004 Journal of Soonchunhyang Medical Science Vol.10 No.1

Background : Extended-spectrum β-lactamases(ESBLs) in gram negative organisms confer resistance to β-lactam drugs such as cefotaxime, ceftazidime and aztreonam. In recent years there has been an increased incidence and prevalence of ESBLs. Thus the purpose of this study was to survey E. coli and K. pneumoniae in order to determine the prevalence of ESBLs. Methods : 637 isolates E. coli of and 328 isolate of K. pneumoniae were collected in Soonchunhyang University Cheonan Hospital during January and December 2003. Isolates investigated for production of ESBLs and susceptible rates for antimicrobial agent by NCCLS methods. Result : ESBL producing E. coli and K. pneumoniae strains were 101 (15.9%) and 43 (13.1%) isolates. The common sources of ESBL producer were lower respiratory specimens and urine. ESBL-producers are more prevalent among isolates in ICU. ESBL producing isolates were lesser susceptible for gentamicin and ciprofloxacin. Conclusion : ESBLs producing E. coli and K. pneumoniae isolates were prevalent in hospital. ESBL-producer were isolated more frequently from lower respiratory specimens and urine, and were lesser susceptible for non-β-lactam drug. Increased incidence and prevalence of strains expressing ESBLs present therapeutic challenges.

최영민,이승휘,김영미,이정호,전성일,이기철 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.1

목 적 : 산후우울증의 발생은 출산 직후부터 1년까지 지속될 수 있고 출산 이후에도 오랜 기간동안 발생 가능성이 있으며, 산후우울증을 단순히 선행하는 감정적 문제, 통제 소재, 사회적지지, 출산과 동반된 생리적 변인만으로 설명할 수 없다. 그러므로 산후우울증은 출산후 산모-영아 상호관계에서 겪게되는 어려운 영아의 기질, 산모가 영아를 양육하면서 겪게되는 양육 스트레스, 그리고 산모의 대처 방식과 연관이 있을 것이다. 본 연구는 산후우울증과 영아 기질, 양육 스트레스, 대처방식을 변인으로 하여 산후우울증과의 연관성을 평가하기위해 산후의 우울성향과 각 변인의 관계를 연구하였다. 방 법 : 연구의 대상은 1996년 7월 16일부터 8월 27일까지 인제 대학교 의과대학 부속 상계백병원 소아과 외래에 예방 접종을 위해 내원한 4개월에서 12개월 사이의 영아를 둔 산모 105명을 대상으로 하였다. Beck우울척도(BDI), 영아기질척도(EAS), 부모 양육스트레스 목록표(PSI), 대처방식척도(WCC)를 사용하여 산후의 우울성향과 이들 변인과의 연관성을 평가하여 다음과 같은 결과를 얻었다. 결 과 : 1) 어머니의 우울성향 점수는 영아의 기질중 부정적 정서성(r=.26 p<0.05), 과도한 활동성(r=.22 p<0.05)과 유의미한 상관 관계를 보였다. 영아의 사회성 척도와는 부적 상관이 있었으나 통계적으로 유의미하지는 않았다. 2) 어머니의 우울성향 점수는 양육 스트레스와는 정적 상관관계가 있었다(r=.44 p<0.001). 3) 어머니의 우울성향 점수와 대처방식과 유의미한 상관관계를 보이지 않았다. 4) 영아의 부정적 정서성과 양육 스트레스는 정적 상관관계가 있었으나(r=.49 p<0.001) 사회성, 활동성과의 상관관계는 유의미하지 않았다. 양육 스트레스와 대처방식과도 통계적으로 유의미한 상관관계를 보이지 않았다. 결 론 : 본 연구 결과, 산모의 산후 우울성향과 첫째, 영아 기질 중 정서성과 활동성이 연관관계가 있고 둘째, 양육스트레스와 연관이 있으나 세째, 대처방식과는 연관이 없었다. 이런 결과는 산후의 우울성향과 각 요인과의 연관성을 살펴볼 때 산후우울증에 더 중요한 영향을 미치는 것은 산모의 대처 방식이라는 어머니 측의 변인보다는 출산과 동반된 양육 스트레스 혹은 영아의 어려운 기질일 것이라고 추론할 수 있다. Objectives : This Study examined the relationship of depressive tendency in postpartum women with psychosocial factors such as infant temperament, parental stress and coping style. Methods : The subjects consisted of 05 postpartum women, each of whom had an infant aged 4 to 12 months. They were assessed on demographic variables and on measures of the depressive symptomatology, infant temperament, parental stress and the coping style using Beck Depression Inventory(BDI), the EAS temperamental survey, Parenting Stress Index(PSI), the Way of Coping Checklist(WCC). And then we assessed the relationship of depressive tendency in postpartum women with psychosocial factors. Results : The results were as follows : 1) Depressive tendency in postpartum women had significant relationship with emotionality(r=.26 p<0.05) and activity(r=.22 p<0.05) of infant temperament. 2) Depressive tendency in postpartum women had significant relationship with parenting stress(r=.44 p<0.001). 3) Depressive tendency in postpartum women had no significant relationship with coping style. 4) Parental stress had significant relationship with emotionality(r=.49 p<0.001) but did not have any relationship with sociability and activity of infant temperament. Parenting stress had no significant relationship with coping style. Conclusion : These results suggest that depressive tendency in postpartum women correlated with emotionality and activity of infant temperament correlated with parenting stress but not correlated with coping style. Infant temperament and parenting stress to child rearing are more significantly correlated with depressive tendency in postpartum women than coping style of postpartum women.

In choosing the appropriate antimicrobial agent for a given bacteria infection, the identity of the infecting organism and the information about the antimicrobial susceptibility of that must be considered. We analyzed antimicrobial resistance of the bacteria isolated from clinical specimens at Soonchunhyang chunan hospital in 2000 and 2001. Most of gram negative rods showed resistance for ampicillin and resistant rates of Enterobacteriaceae for 3rd generation cephalosporin were significant. Fluoroquinolone resistance rate was 75.9% in Acinetobacter baumannii. The ceftazidime, fluoroquinolone and imipenem resistant Staphylococcus aureus and penicillin resistance Streptococcus pneumoniae are prevalent. No Staphylococcus showed resistance for vancomycin was detected. Vancomycin resistant rate in enterococci was insignificant. To prevent the emergency of new resistance for antimicrobial agent and spreading of multidrug resistant bacteria, we believe that policy and action for prevention to hospital infection and appropriate use of antimicrobial agent are necessary.
