The newly developed diagnostic method with application of $^{113}Sn-^{113m}In$ cow system ($^{113}Sn:\;T\frac{1}{2}$ 118 days, $^{113m}In:\;T\frac{1}{2}$ 1.7 hrs, 390 Kev, Single ${\gamma}$) has the remarkable advantages such as increased diagnostic ability by single large dose administration of $^{113m}In$ with no subsequent radiation hazard and shortened examining time. We reformed the research of following scope with the use of developed $^{113}Sn-^{113m}In$ cow (25 mCi) generator: The sizes of particles produced under various conditions were investigated, and possibility for application to the scannings of various organs such as brain, liver, lung, bone marrow and blood pool etc. were studied. Results: $^{113m}InCl_3$ solution eluted from diluted HCl solution (pH 1.5) passed through $^{113}Sn-^{113m}In$ generator, and there can be produced various sized particles of colloidal indium. And there observed the state of distribution of $^{113m}In$ in each organ which showed many differences according to the particle sizes of colloidal indium. The results are stated as follows: 1. The adjustment of pH is the most important factor in making the desirable particle size of colloidal indium. The colloid for blood pool showed the highest level as 7.1%/gm blood, at pH 1.7, the colloid of pH 3.5 for liver scanning showed the highest level, 88.4%, in the liver, the colloid pH 6 showed the highest level, 3.1%, in the spleen, and the colloid of pH 11.0 showed the highest level, 85.3%/gm, in the lung. 2. The colloid for liver scanning made with NaCl-NaOH system showed the highest liver uptake at pH 7.2, and at either higher or lower pH than 7.2 showed decrease of liver uptake more or less. 3. The activity of $^{113m}In$ eluted through $^{113}Sn-^{113m}In$ generator indicated over 90% in the initial 4 ml, and particularly 88.1%-86.0% in the initial 2 ml. 4. The incubation time, tempertaure and mechanical irritation related to colloid formation and coating of colloid were not the definite condition of influence.

연구배경: 식세포인 호중구나 단핵세포는 생체 외실험에 사용하기 위한 세포분리법인 플라스틱 표면부착만으로도 세포활성화가 일어나 이후의 실험결과에 영향을 주고 이 과정에 염증반응과 관련된 물질의 유전자 전사 및 부착분자가 연관되어 있는 것으로 알려져 있다. 폐의 주된 면역세포인 폐포대식세포도 대부분 플라스틱 표면부착에 의해 세포를 분리하므로 사람의 폐포대식세포가 표면부착 자체에 의해 활성화되고 여기에 염증관련 유전자 및 부착분자가 관여하는지를 알아보기 위해 연구를 시행하였다. 방법: 적어도 한 쪽 폐가 정상인 사람에서 기관지폐포세척술을 통해 얻은 폐포대식세포를 대상으로 표면부착이 미치는 영향을 얄아보기 위해 부유상태와 부착상태에서 각각 시간에 따른 lL-8, SOD 및 CD11/CD18 mRNA 발현을 Northern blot analysis로 분석하였고 PMA와 fMLP로 추가 자극했을 경우 차이를 보이는지 알아 보았다. 결과: 1) 플라스틱 표면에 부착시킨 폐포대식세포는 염증 또는 면역에 관계되는 IL-8 mRNA 및 SOD mRNA의 발현이 부착시간 정과에 따라 증가하여 부착 8시간후에 최대로 나타났으나 CD18 mRNA 발현은 부착에 의해 증가되지 않았다. 2) 이런 mRNA의 증가는 PMA에 의해서는 부착여부와 관계없이 유도되었지만 fMLP에 의해서는 부착된 세포에서만 유도되었다. 결론: 이상의 결과로 플라스틱 표면부착에 의해 폐포대식세포에서 염증매개성 물질의 유전자발현이 증가되며 이는 표면부착에 의한 세포 활성화와 관계가 있을 것으로 생각된다. Background: Neutrophils or monocytes separated in vitro by the adherence to plastic surface are known to be activated by surface adherence itself and subsequent experimental data might be altered by surface adherence. Adhesion molecules and gene transcription of the inflammatory mediators are known to be associated in this process. To evaluate whether adhesion molecule and transcriptional activation of the inflammatory substances are also involved in the activation of human alveolar macrophage by the adherence procedure, we designed this experiment. Method : Bronchoalveolar lavage was performed in the person whose lung of either side was confirmed to be nonnal by chest cr and alveolar macrophage was harvested. To measure the expression of Interleukin-8(IL-8) mRNA, manganese superoxide dismutase(SOD) mRNA and CD11/CD18 mRNA in human alveolar macrophage of both adherence state and suspension state, Northern blot analysis was done at 0, 2, 4, 8 and 24hrs after the adherence to plastic surface and during suspension state. Then, phorbol myristate acetate(pMA) and N-formyl-methionyl-leucyl-phenylalanine(fMLP) were added respectively in the same experimental condition. Result : 1) Human alveolar macrophages in the adherent state induced IL-8 mRNA and SOD mRNA expression which was maximal at 8 hours after the adherence to plastic surface. But we could not observe the upregulation of CD18 mRNA by surface adherence. 2) PMA induced these mRNA expression both in the adherent cell and the nonadherem cells, but the induction of mRNA expression by fMLP occurred only in the adherent cells. Conclusion: These results suggest that adherence of huamn alveolar macropahge is an important cell-activating event that may play a critical role in the modulation of lung inflammatory respones.

We report a rare case of primary tracheal malignent melanoma documented by careful clinical examination. Differentiation between primary and metastatic malignant melanoma is very difficult We conclude that this tracheal tumor is a primary malignant melanoma based on characteristic pathologic features and the exclusion of the possibility of spontaneous regression of the primary site by patient's history and physical examination.

Invasive pulmonary aspergillosis is a disease occuring predominantly in patients with defects in immunity such as neutropenia, hematologic malignancies or with defects in cell-mediated immunity. The isolation of Aspergillus from respiratory tract of normal host usually signifies tracheobronchial colonization, making this diagnosis difficult. There are isolated case reports occuring in normal hosts but most of them were diagnosed postmortem at autopsies indicating that early diagnosis of invasive aspergillosis in normal host is difficult. We describe here a case of invasive aspergillosis in a immunocompetent host diagnosed by lung biopsy which was successfully treated with Amphotericin-B. Invasive pulmonary aspergillosis should be included as one of the differential diagnosis if a patient with pneumonic consolidation does not respond to usual therapy, even if the patient does not have any defect in immunity.

목적 : 주요 기도의 악성 종양으로 인한 호흡기 증상은 적절한 조치를 취하지 않을 경우 때로는 환자의 생명을 위협할 정도로 위급한 경우가 있으며 환자의 삶의 질을 저하시키는 주요 원인이 된다. 이러한 호흡기 증상의 완화를 위하여 적용한 기관지 내시경을 이용한 고선량율 기관내 근접 조사 방사선차료의 단기 임상 관찰 결과를 보고하고자 한다. 대상 및 방법 : 1994년 12월부터 1996년 3월까지 원발성 또는 전이성 폐암으로 인한 기도폐쇄 와 이로 인한 주요 호흡기 증상이 있는 25명의 환자들에 대하여 고선량율 기관내 근접 조사 방사선치료를 시술하였다. 원발 병소는 비소세포성 폐암이 21례 ($84\%$), 원발성 기관암이 3례($12\%$), 재발된 식도암이 1례였다. 20명의 환자들에 대하여는 외부 조사 방사선치료를 병행하였으며, 급성 기도 폐쇄로 위급한 증상을 호소하였던 6명의 환자에 대하여는 응급 기관내 Laser 소작술을 먼저 시행하였다. 기관내 근접 조사 방사선치료는 모든 환자에서 각 3회씩 시행하도록 예정하였으며 모두 70회의 치료를 시행하였다. 결과 : 기관내 근접 조사 방사선치료의 전후로 조사한 주요 호흡기 증상은 기침, 호흡곤란, 각혈, 폐쇄성 폐렴이 각각 $88\%$ (22/25), $96\%$ (22/23), $100\%$ (15/15), $100\%$ (9/9)에서 호전되었으며, 환자의 일반 활동도 (ECOG performance score)는 전체 환자의 $56\%$에서 호전되었고 악화된 경우는 없었다. 관찰 기간 동안 15명이 사망하였으며 치료 개시로부터 사망까지 기간의 중앙값은 4개월 (범위: 1개월$\~$17개월) 이었고 10명의 생존자들의 생존 기간의 중앙값은 9개월 (범위: 5개월$\~$19개월)이었다. 치료 후 1년 이상 생존한 환자는 5명이었으며 이들 모두에선 원발 병소의 완전 관해를 확인할 수 있었다. 사망자들은 모두 원발 및 전이 병소의 진행으로 인한 경우였다. 대량 각혈로 사망한 경우는 4명이었으며 이 중 3명은 응급 기관내 Laser 소작술을 선행하였던 경우였다. 결론 : 기관지 내시경을 이용한 기관내 근접 조사 방사선 치료는 기도의 악성 병변시 호흡기 증상 및 환자의 활동도를 호전시키는 데 매우 효과적인 치료 방법이다. 저자들의 관찰 경험을 바탕으로 하여 기관내 근접 조사 방사선치료는 근치적 방사선치료의 국소 추가 방사선 조사의 한 방법으로 적용할 수 있을 것으로 판단된다. Purpose : Respiratory symptoms related with malignant airway disease have been the main causes of lowered qualify of life and also sometimes may be life-threatening if not properly managed. The authors report the short-term experiences of endobronchial brachytherapy for symptomatic malignant airway obstruction using high dose rate after-loading brachytherapy unit. Materials and Methdos : Twenty-five Patients with symptomatic malignant airway obstruction were treated with endobronchial brachytherapy between the period of December 1994 and March 1996 at Department of Radiation Oncology of Samsung Medical Center Twenty-one ($84\%$) were patients with non-small cell lung cancer, three with tracheal malignancies, and one with recurrence of esophageal cancer. Twenty Patients were given elective external beam radiation therapy, while six were given endobronchial laser evaporation therapy on emergency bases in addition to endobronchial brachytherapy. Three procedures for each patient were planned and total of 70 procedures were completed. Results : Improvement rates of major respiratory symptoms after endobronchial brachytherapy procedures were $88\%$(22/25). $96\%$(22/23), $100\%$ (15/15), and $100\%$(9/9) for cough, dyspnea, hemoptysis and obstructive pneumonia, respectively. ECOG performance scores were improved in $56\%$ of total patients group, while there was no case with worsened ECOG score. Fifteen patients died and the median interval from the start of treatment to death was 4 months (range: $1\~17$ months), while that of ten survivors was 9 months (range $5\~19$ months). There were five patients with controlled intrathoracic disease, who have survived over one rear. All deaths were associated with uncontrolled local and/or distant disease. Four Patients died of massive fatal hemoptysis, three of who received emergency endobronchial laser evaporation therapy before the start of endobronchial brachytherapy. Conclusion : Endobronchial brachytherapy has been confirmed as an excellent palliative treatment modality improving respiratory symptoms as well as patients' general performance status. Based on the current observations, use of endobronchial brachytherapy in curative setting as a boost technique may be warranted.
