        조수철,김재원,신민섭,황준원,한상원,박관현,이상돈,김경도,김건석,서홍진,이유식,정재용,김영균,문두건,남궁미경,한창희,조원열,김영식,배기수,이종국,정우영,신의진 大韓神經精神醫學會 2005 신경정신의학 Vol.44 No.6

        Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

        정원모,주관식,황한렬,정원균 연세대학교 자연과학연구소 1986 學術論文集 Vol.17 No.-

        동일한 선원에 대한 감마-감마, 감마-내부전환전자 각상관관계 실험을 통하여 변형핵인 ^152Sm의 혼합비(δ)와 121.8keV전이의 내부 전환전자 입자매개변수(b_2)를 결정하였다. 감마선을 검출하는데는 두대의 Ge(Li)검출기를 내부전환전자를 검출하는 데는 표면장벽형검출기를 사용하였다. 실험을 통하여 다음과 같은 결과를 구하였다. 244.7 keV-121.8 keV ; δ =-0.012±0.007 688.6 keV-121.8 keV ; δ =17.4±3.01 964.0 keV-121.8 keV ; δ =9.51±1.93 1112.0 keV-121.8 keV ; δ =12.30±2.05 1408.0 keV-121.8 keV ; δ =0.16±0.07 964.0 keVγ-121.8 keVe_K ; b_2=1.66±0.26 1408.0 keVγ-121.8 keVe_K ; b_2=1.63±0.10 1408.0 keVγ-121.8 keVe_L ; b_2=0.99±0.13 혼합비는 PPQ(Pairing-Plus-Quadrupole)모델과 IBA(Interacting-Boson-Approximation)모델로부터 얻은 이론값과 비교하여 보았고 또한 입자매개변수값이 이론값과 큰 차이가 있는 것으로 보아 변형핵의 저에너지 E_2 전이에서 ‘anomaly’가 있는 것으로 추정된다. The mixing ratios (δ) and the internal conversion electron particle parameters (b_2) of the 121.8keV transition in deformed ^152Sm nuclei were determined by comparing the γ-γ and γ-e angular correlation measurements made with the same source. The experimental apparatus was constructed with a surface barrier detecter for electrons and two Ge(Li) detectors for gamma rays. The following results were obtained. 244.7 keV-121.8 keV ; δ =-0.012±0.007 688.6 keV-121.8 keV ; δ =17.4±3.01 964.0 keV-121.8 keV ; δ =9.51±1.93 1112.0 keV-121.8 keV ; δ =12.30±2.05 1408.0 keV-121.8 keV ; δ =0.16±0.07 964.0 keVγ-121.8 keVe_K ; b_2=1.66±0.26 1408.0 keVγ-121.8 keVe_K ; b_2=1.63±0.10 1408.0 keVγ-121.8 keVe_L ; b_2=0.99±0.13 The results are compared with the theoretical values derived from the Pairing-Plus-Quadrupole model and from the Interacting-Boson-Approximation model, and an 'anomaly' was found in the low-lying E_2 transition for deformed ^152Sm nuclei.

      • Ki-67이 Luminal B형 유방암 환자의 예후에 미치는 영향

        류동원,최우식,이충한 고신대학교 의과대학 2010 고신대학교 의과대학 학술지 Vol.25 No.1

        배경: Ki-67는 세포의 분열지수로서 특히 세포분열초기 나타나는 것으로 알려져 있다. 그래서 Ki-67의 분열지수가 높은 경우 조기 재발 및 예후와 관련되어 있다는 보고가 있다. 본 연구에서는 본원의 자료를 토대로 Ki-67의 분열지수가 예후에 영향을 미치는지를 알아보고자 한다 방법: 2001년 1월부터 2005년 12월까지 본원에서 유방암으로 수술을 받은 679명의 환자를 대상으로 후향적으로 조사를 하였다. 술후 조직병리학적 보고서를 토대로 조사하였다. Ki-67의 수치를 기준으로 10%이하군, 10%에서 20%군, 20%이상군으로 나누었다. 세군사이의 임상병리학적 요소의 분포를 비교하였으며 Kaplan-Meier를 이용하여서 생존율을 분석하였다. 결과: 환자들의 평균나이는 46세였으며, 평균종양의 크기는 3.2cm였다. 20%이상군에서 진행성 유방암환자의 비율이 높았다.(p=0.007) 특히 림프절의 전이정도와도 관련이 있었다.( p=0.003) 그러나 Ki-67과 생존율과는 의미있는 관련성을 없었다.( p=0.6112). 결론: 본원의 조사에 따르면 Ki-67은 진행성 유방암과 호르몬 수용체 음성과는 밀접한 관계를 가지고 있었으나 생존율에는 영향을 미치지 않았다. 그러나 본조사는 추적기간이 짧고 조사 규모가 크지 않아서 향후 계속적으로 추적 관찰한다면 더 의미있는 결과과 나올것이다. Background: Ki-67 expression has been considered to be a reliable marker for assessing tumor cell proliferation. The aims of the ourstudy were to assess the correlationbetween Ki-67 expression and clinocopathologic factors and to analyze the effect of Ki-67 expression on survival rate. Methods:The study subjects, 679 women with breast cancer, were a subset of patients operated at OOO hospital from Jun 2001 to Dec 2005.Patients are grouped into 3 categories according to Ki-67 determined in surgical specimens. Clincopathologic factors were compared with 3 categories of Ki-67. Chi-squared tests were used for statistical analysis. Kaplan–Meier estimates are presented for thesurvival function, and differences in survival were analyzed usingthe log rank test. Results: The median age was 46yrs, and median tumor size was 3.2cm. The strong correlation was observed between tumor staging and Ki-67 staining(p=0.007) and Group III(more than 20% staing) showed more advanced N-staging(p=0.003). The number of patients with estrogen receptor negative was higher in Group III(p=0.001) and that with HER-2 receptor positive was also higher in Group III(p =0.001) comparing with other groups. The univariate analysis for prognostic factors associated with DFS revealed that both the tumor groupas T1, T2, T3 or T4 and lymph node as N0, N1, N2 or N3 were statistically significant(p=0.0003 and p=0.0015 respectively) but the Ki-67 staining as <10%, 10~20%, >20% was statistically not significant(p=0.6112). The univariate analysis for prognostic factors associated with OS revealed that Tumor staging and N-staging was statically significant(p=0.003 and p=0.0015 respectively). Conclusions: According to our study, Ki-67 positive groups was associated with more advanced staging, ER-negative, PR-negative and HER-positive respectively. But there is no significant association between Ki-67 staining and 5-year disease free survival rate including overall survival rate.

      • Interleukin-2가 Mouse간의 인산염분해효소의 활성에 미치는 영향

        이규식,김원규,정호삼,강성섭 한양대학교 의과대학 1989 한양의대 학술지 Vol.9 No.1

        In recent years, interleukin-2, a lymphokine produced by antigen or mitogenstimulated lymphocytes, has been intensively with the development of immunooncology and chemoimmunotherapy of the malignant tumor. Interleukin-2 mediates antitumor effect by stimulating the proliferation of helperand cytotoxic T cells, augmenting the cytolytic activities of cytotoxic T-lymphocytes and differentiating T-lymphocytes into a lymphokine-activated killer cell in vivo. Thus interleukin-2 induces the therapeutic effects on various sarcoma and carcinoma and regresses the pulmonary, hepatic and peritoneal metastases of various tumors. Although interleukin-2 is very effective for the treatment of various malignancy, it develops many side effects including fever, chill, malaise, mental confusion, diarrhea, vomiting and oliguria and causes pulmonary, hepatic and renal toxicities. Especially interleukin-2 results in increase of capillary permeability with weight gain, pulmonary edema, and ascites. In this experiment, the author studied the effect of interleukin-2 on the mouse liver, histochemically observing the changes in the activities of alkaline phosphatase, acid phosphatase and adenosine triphosphatase. Male mice, DDY strain, weighing 20gm, were used as experimental animals. The experimental animals were sacrificed at 3, 6, 12, 24 and 48 hours after intraperitoneal administration of two milions unit of interleukin-2 per kilogram of body weight. The specimens obtained from the liver were fixed in 10% neutral buffered formalin solution for 24 hours at 4℃ and sliced at 16㎛ thickness in a frozen cryostat. The activities of alkaline phosphatase and acid phosphatase were observed by the Gomori's method and the activity of adenosine triphosphatase was observed by the Wachstein and Meisel's method for histochemical study. The results obtained were as follows. 1. The acid phosphatase activity was strong positive at 12 hours and 24 hours groups in the central and portal zones of the liver lobules, but weak positive and moderate positive at 48 hours group in the central and portal zones of the liver lobules, respectively. 2. The alkaline phosphatase activity was weak positive at 6 hours and 12 hours groups and moderate positive at 48 hours group in the central and portal zone of the liver lobules. 3. The adenosine triphosphatase activity was trace positive in the central zone and weak positive in the portal zone of the liver lobules at 6 hours group but moderate positive at 48 hours group in the central and portal zones of the liver lobules. Consequently, it is suggested that interleukin-2 induce degenerative changes of the hepatocytes of the mouse, but it is recovered with time.

      • Chlorambucil이 Mouse 심근 조직에 미치는 영향에 대한 실험적 연구

        박원학,정형재,이충식 충남대학교 의과대학 지역사회의학연구소 1989 충남의대잡지 Vol.16 No.2

        The cardiotoxic effects of high dosage (20㎎/Kg) of chlorambucil (CA) given inrperitoneal injection were evaluted for each time interval (1, 3, 4, and 14 day) in 162-days ald A/J Swiss Ablino mice. Histological alterations of myocarcium reveal thet during the early stage (3 day) of CA administration there is “wavy myocardium”. In CA adiministration for 7 days, myocardial changes included vacuolar degeneration and occur ence of contraction bands. More advanced myo-cardial lesions are characterized by myofibrillar loss, separation of intercalared disc and interstitial fibrosis. With lapse of time, these morphological changes were developed. In histochemical studies, the number of glycogen granules in myocardium showed decrease with time. Myocardial lipid deposition stained by Oil-red-O was significantly increase in vaculoar and perivacuolar region of mice receiving for 14 days of administration. Myocardial calcium concentration was a slight increase in 14 days administration. Significant increase of serum creatine phosphokinase preceded the severe histological alteration and CPK values returned to control ranges in 14 days of administration. This which was combined with the function of the myocardium at serum CPK level, may play an important parameter to cardiotoxicity.
