1. 목적 급성백혈병의 화학요법에 있어서 관해유도 요법시에 보다 더 강력한 항암화학요법을 시행하고 골수억제의 회복을 위하여 말초혈액에서 채취한 조혈모세포의 투여로 그 효과를 증대시키고자 시도하였다. 2. 방법 관해유도 화학요법후에 골수억제시기로부터 회복단계로서 백혈구감소증이 호전도면서 단핵세포가 증가될 때에 말초혈액에서 조혈간세포(stem cell)로 인정되고 있는 CD34+세포의 함유량이 1% 이상되는 시기를 찾아내고 그 때부터 평균 4차례의 단핵구를 분리채집을 하여 -74。C에 냉동보관하였다가 제2차 화학요법후에 해동시켜서 정맥주입하였다. 3. 결과 대상 급성백혈병환자는 6명에 23회의 조혈간세포를 함유한 단핵구 채집을 시행하였고 유효한 단핵구의 채집은 4례에서 가능하였고 2례에서는 유효한 채집이 못되었다. 채집효율은 39.0-74.5%로서 평균 49.8%였다. 채집 후에 혈액학적 변화는 혈색소의 약간 감소 (평균 1.34g/dl)와 혈소판의 감소 (평균20.25%)를 나타내었다. 해동 단핵구를 투여할시에 일과성인 불쾌감, 기침, 흉부압박감, 호흡곤란 등이 있었다. 4. 결론 자가골수이식에서 자기말초혈액조혈간세포이식으로 관심이 이행되는 현시점에 자가조혈간세포를 채집하여 수혈하는 기술이 확립되는 기초를 이루었다고 본다. 이번 대상들은 재발된 금성백혈병들에 시행하였으나, 향후에는 초발시에 제일차 관해유도 화학요법 과정에 시도해야할 것으로 생각한다. Object: Peripheral blood stem cells(PBSC) were collected after remission induction chemotherapy and reinfused after intensified chemotherapy in order to increase the chemotherapeutic efficacy. Method: Collection of mononuclear cells (MNC) was started when CD34+ cells above 1% and WBC above 1,000/ul with mononuclear cell percentage above 30%, the collection procedures were done 2-6 time in each patient of total 6 cases. The collected MNCs were stored in - 750C and reinfused after thawing in the water bath at 370C Results: Twenty three collection procedures from the 6 cases of acute leukemia had made effective MNC collection in 4 cases and mean collection efficiency was 49.8%(from 39.0% to 74.5%). Hematological changes after the procedure were mean reduction of hemoglobin 1.34g/dl and mean 20.25% of decreased platelet count. There were noticed transient symptoms of discomfort, coughing, chest tightness and dyspnea in association with the infusion of stored cells. Conclusion: The basic process for the peripheral blood stem cell transplantation (PBSCT) was accomplished with this supportive care for the consolidation chemotherapy of acute leukemia. Effective PBSCT would be warrented with more qualified process and high does chemotherapy. (Korean J Blood Transfus 6(2) : 41~47,1995)

박경식,이승현,최석영,박태규,이동화,이찬우,정성복,이인규 啓明大學校 醫科大學 1997 계명의대학술지 Vol.16 No.3

부신피질 자극호르몬 단독결핍은 국내에서 7례만이 보고된 희귀 질환이며 병인 및 경과 등 아직 불분명한 측면이 많다. 이는 질환지체의 희귀성도 있지만 치료후 자연경과에 대한 장기적인 추적검사가 이루어진 경우가 드물기 때문이기도 하다. 저자들은 비특이적인 전신증상을 주소로 내원한 폐경기후의 56세 여자 환자에서 자가면역질환의 증거없이 고프로릭틴혈증을 보인 부신피질 자극호르몬 단독결핍 1례를 경험하고 1년간의 부신피질호르몬 대치요법후 추적검사를 실시하였기에 문헌 고찰과 함께 보고하는 바이다. Isolated ACTH deficiency is a rare disorder which shows secondary adrenal insufficiency with normal states of other pituitary hormones. A 56-year-old postmenopausal woman complaining general weakness and intermittent mental confusion presented negligible serum cortisol and ACTH level with hyperprolactinemia and mild hyponatremia. Rapid ACTH stimulation test did not show significant increase of serum cortisol level. Combined pituitary stimulation test showed negligible response of cortisol and ACTH, and slightly decreased response of prolactin and gonadotropin. But the responses of TSH and GH were normal. There was no evidence of organic pituitary of hypothalamic lesion in brain MRI and antithyroid autoantibody was not detected in serum. After receiving 12 months of glucocorticoid replacement therapy, she skipped the medicine for 3 weeks and we performed follow-up endocrinologic tests. Serum ACTH and cortisol level was also negligible and prolonged ACTH simulation test showed normal response of serum cortisol. CRF stimulation test showed no response of serum ACTH. Basal prolactin level was decreased to near normal and combined pituitary stimulation test showed normal response of prolactin with slightly blunted response of TSH and GH. We concluded that the case was nonautoimmune origined isolated ACTH deficiency which was accompanied by hyperprolactinemia and resultant deficiency of gonadotropin, so we report this case with review of literatures.

천경아,조인호,원규장,이경희,이형우,현명수,이재태,이규보 영남대학교 의과대학 2002 Yeungnam University Journal of Medicine Vol.19 No.2

Purpose; Ga-67 scintigraphy has been used for the evaluation of tumors, especially lymphoma. Recently, Tl-201 and Tc-99m MIBI were also used to tumor imaging. Tl-201 and Tc-99m MIBI had better physiologic characteristics than Ga-67, so we studied 32 biopsy proven lymphoma patients (male 24, female 8, mean age 46 years) with Ga-67, Tl-201 or Tc-99m MIBI and compared the scan findings. Materials and Methods: Twenty-three of 32 patients were injected 74-111 MBq (2-3 mCi) of Tl-201, before chemotherapy and imaged with dual-headed SPECT (Prism 2000, Picker, USA) at 30 minutes after injection. Delayed images were obtained after 3 hr in 8 patients. Twenty seven of 32 patients were injected 740 MBq (20 mCi) of Tc-99m MIBI and imaged at 30 minutes after injection. 111-185 MBq (3-5 mCi) of Ga-67 was injected in 12 patients and imaged at 48 and 72 hours after injection. Twenty eight patients were diagnosed as non-Hodgkin's lymphoma and others were Hodgkin's lymphoma. Results: Twenty patients were positive on Tl-201 scan and 3 patients showed negative findings. One of these 3 patients, Tc-99m MIBI and Ga-67 scan were positive. Twenty two patients were positive on Tc-99m MIBI scan and 5 patients showed negative findings. One of these 5 patients, Tl-201 was positive and 2 were positive on Ga-67 scan. Ten of 12 patients showed positive findings on Ga-67 scan. The sensitivity of these agents were 83.3%, 87.0% and 81.5% for Ga-67, Tl-201 and Tc-99m MIBI, respectively. The sensitivity was highest in Tl-201 scan, but there were no significant differences among three tests. In this study, there was no significant difference of uptake ratios between early and delayed images of Tl-201. Conclusion: Scintigraphy with Tl-201 and Tc-99m MIBI in lymphoma patients have similar sensitivity with Ga-67.

정신분열병 환자에서 사회인구학적 특징과 종교에 따른 정신병 치료방법에 대한 선호도

이창민,이종일,신경희,이민규,김태현 大韓神經精神醫學會 2001 신경정신의학 Vol.40 No.5

연구목적 : 종교가 정신분열병 치료에 도움을 주기도 하지만 정신병 치료방법에 대한 잘못된 개념을 심어주어 환자의 치료순응도에 나쁜 영향을 미치기도 한다. 그러므로 종교에 따른 정신병 치료방법에 대한 선호도를 조사하여 종교가 정신분열병 치료에 미치는 영향을 알아보고자 이 연구를 시행하였다. 방 법 : DSM-Ⅳ에 의해 진단 받았으며 GAF score가 41이상은 정신분열병 환자 102명을 대상으로 하였다. Allport와 Ross의 내재적-외향적 종교성향척도를 이용하여 종교성향을 설문 조사하였으며 정신병 치료방법(초자연적 치료, 원시적 약물치료, 심리적 치료, 종교적 치료, 생물학적 치료)에 대한 선호도를 설문 조사하였다. 수집된 자료에서 사회인구학적 특성과 종교성향 그리고 정신병 치료방법의 관계를 비교 분석하였다. 결 과 : 1) 정신분열병 환자는 생물학적 치료와 심리적 치료에 가장 높은 선호도를 보였으며 다음으로 종교적 치료와 원시적 약물치료에 높은 선호도를 보였다. 2) 기독교를 믿는 환자군은 종교적 치료에 유의한 선호도를 보인다. 3) 내재적 성향의 환자군이 반종교적 성향의 환자군에 비해 심리적 치료에 유의하게 높은 선호도를 보였다. 그리고 친종교적 성향의 환자는 초자연적 치료, 심리적 치료 그리고 종교적 치료에서 유의하게 높은 선호도를 보였다. 결 론 : 전반적으로 종교성향과 정신병 치료방법은 유의한 상관관계를 보이지 않았다. 그러나 종교성향은 특정한 교리나 사상을 반영하기보다는 개인의 성격을 반영하는 경향이 있으므로 종교과 정신병 치료방법이 전혀 무관하다고 할 수 없다. 환자들은 종교적 치료와 원시적 약물치료에 상당한 선호도를 보이고 있으며 특히, 기독교를 믿는 환자군은 종교적 치료에 유의한 선호도를 보인다. 그러므로 환자와 가족에게 정신분열병에 대한 정신교육을 지속적으로 시행해야 한다고 여겨진다. Objectives : Religion may be beneficial to the treatment of schizophrenia, but religion frequently have bad influence on drug compliance because religion give false concept of the treatment of psychosis. We investigated the influence of religion on the treatment of schizophrenia by assessing the preference for the treatment of psychosis to religion. Methods : 102 patients of schizophrenia who were diagnosed by DSM-Ⅳ and above 41 scores of GAF score were selected. We assessed religious orientation with the Intrinsic and Extrinsic Religious Orientation Scale and assessed the preference for the treatment method of psychosis(supernatural treatment, primitive medicinal treatment, psychological treatment, religious treatment, biological treatment). The relationship among the variables of demographic data, religious orientation, the treatment method of psychosis were analyzed. Results : 1) Schizophrenic patient showed first preference for biological treatment and psychological treatment and they showed second preference for religious treatment and primitive medicinal treatment. 2) Protestant showed preference for religious treatment. 3) Patient group who have intrinsic religious orientation showed more preference for psychological treatment than patient group who have antireligious orientation. Conclusions : Generally the relation between religious orientation and the treatment method of psychosis was not significant. But it couldn't be said that religion and the treatment method of psychosis was not related because religious orientation was not related with religious ideology but was related with personality. Schizophrenic patient showed more preference for religious treatment and primitive medicinal treatment and specifically, protestant showed preference for religious treatment. Therefore, we suggest that it is necessary to give persistent education about schizophrenia to patients and their family.

이규철,유근민,김경석,박홍태 울산대학교 1996 공학연구논문집 Vol.27 No.2

본 연구에서는 주위 환경 열화에 따른 복합절연재료의 절연특성과 수명을 향상시키기 위해 고온에서 흡습량을 변화시켰을 때와 탈습량을 변화시켰을 때 흡십시료와 탈습시료의 전기적 특성 및 기계적 특성을 조사하였다. 유리섬유 각층의 흡습상수는 각각 1층에서 0.0117, 2층에서 0.0123, 3층에서 0.0152를 나타냈다. 전기적 특성 및 기계적 특성은 복합재료의 흡습에 따라 크게 떨어졌다. 70℃에서 습기가 완전히 건조되어도 흡습전의 전기적 및 기계적 특성을 얻기가 어려운 것으로 나타났다. 수분에 의해 발생한 복합절연재료내에 존재하는 많은 결함들은 에폭시 메트릭스와 필라사이에 존재하였다. The electrical and mechanical properties of moisture absorbed and moisture desorbed specimens were investigated to improve the insulating characteristics and the reliability of composite materials against environment aging. Moisture absorption constants with the layers of glass fiber showed 0.0117 in 1 layer, 0,0123 in 2 layer and 0.0152 in 3 layer, respectively. Although moisture was removed at 70℃, it was impossible to obtain the initial electrical and mechanical properties. Many defects induced by moisture were observed at the interface between epoxy matrix and filler in composite materials.
