Among the lymphoreticular infiltrative disorders of the lung, the primary pulmonary lymphomas are rare, and secondary lung involvement of mediastinal lymphomas are more common. Histopathologically, the majority of primary pulomonary lymphomas are small cell lymphomas which have favorable outcomes, and the remainder are more aggressive non-small cell lymphomas, the majority of which are of large cell type. The majority of the primary pulmonary lymphomas are of B cell originating from bronchus associated lymphoid tissue. It is important to differentiate the primary pulmonary lymphomas from benign lymphoreticular infiltrative disorders, such as pseudolymphoma or lymphocytic interstitial pneumonitis. Especially, primary T-cell lymphomas of the lung show polymorphic lymphocytic infiltrations, which make it even more difficult to differentiate from benign infiltration. Diagnosis of the T-cell lymphoma requires immunohisto-chemical stain showing monoclonal T cell proliferation. Primary pulmonary lymphomas of T-cell origin are rarely reported, and almost all of the cases reported had grave prognosis. we report a case of primary pulmonary lymphoma of non-small cell type with liver involvement, which, despite of T-cell origin, had a chronic clinical course and was suggested to evolve from angiocentric immunoproliferative lesion to frank T-cell lymphoma.

Endobronchial lipoma is a rare, benign neoplasm of the large bronchi, which makes up about 0.1 percent of all lung tumors. It can uce irreversible parenchymal lung damage or bronchiectasis if diagnosis and treatment are delayed. The treatment of endobronchial lipoma is early removal and surgical procedures depend on the status of distal parenchymal lung damage. We experienced a case of endobronchial lipoma in 53 year-old female patient, which caused total collapse of left lung and save left lung by enucleation of tumor via bronchotomy.

There are several reasons to take X-ray in case of inpatients. Some of them who cannot ambulate or have any risk if move are taken portable X-ray at their wards. Usually, in this case, many other people-patients unneeded X-ray test, family, hospital workers etc-are indirectly exposed to X-ray by scatter ray. For that reason I try to be aware of free space scatter dose accurately and make the point at issue of portable X-ray better in this study. kVp dose meter is used for efficiency management of portable X-ray equipment. Mobile X-ray equipment, ionization chamber, electrometer, solid water phantom are used for measuring of free space scatter dose. First of all the same surroundings condition is made as taken real portable X-ray, inquired amount of X-ray both chest AP and abdomen AP most frequently examined and measured scatter ray distribution of two tests individually changing distance. In the result of measuring horizontal distribution with condition of chest AP it is found that the mAs is decreased as law of distance reverse square but no showed mAs change according to direction. Vertical distribution showed the mAs slightly higher than horizontal distribution but it isnt found out statistical characteristic. In abdomen AP, compare with chest AP, free space scatter dose is as higher as five-hundred times and horizontal, vertical distribution are quite similar to chest AP in result. In portable X-ray test, in order to reduce the secondary exposure by free space scatter dose first, cut down unnecessary portable order the second, set up the specific area at individual ward for the test the third, when moving to a ward for the X-ray test prepare a portable shielding screen. The last, expose about 2m apart from patients if unable to do above three ways.

Castleman 씨 병 9 예에 대한 임상적 고찰

김성규,한지숙,김세규,이원영,장준,정소영 대한내과학회 1996 대한내과학회지 Vol.51 No.1

Castleman's disease is a rare disease characterized by proliferation of follicle and capillary of lymph nodes. This disease consists of localized or systemic(or multicentric) forms by clinical manifestations and hyaline-vascular type or plasma cell type, histologically. Specific causes of this disease are not known, but some suggest that chronic inflammatory reaction or abnormal immunologic reaction of lymph odes to exogenous stimuli. Complete surgical resection cures most localized forms, but systemic forms often have progressive clinical courses despite of corticosteroid or systemic combination chemotherapy. We report those clinical characteristics with a brief review of literature in 9 cases of Castleman's disease including 3 systemic forms.

The objective of this study is to find out the optimum conditions and characteristic of zinc-nickel alloy electrodeposition in an alkaine bath. The results show that it is known from the polarization curve that nickel in the zinc-nickel bath is deposited at -1.0V. Also, increasing the nickel concentration in the bath increases the nickel content in the alloy deposit. Increase in current density from 0.2 to 0.5A/d㎡ decreases the nickel content in the alloy deposit, significantly. Electroplating of zinc-nickel alloy in an alkaine bath appears anomalous codeposition, zinc being the less noble metal deposit in preference to the more ncble nickel. Temperature within the range of 50℃ has no appreciable effect on the content of nickel in the alloy deposit. But the nickel content in the alloy deposit increase dramatically in the range of more than 60℃. Generally, the nickel content of alloy deposit obtained from an alkaline bath maintains below 10 wt% under the following optimum conditions; Zn conc. 10g/l·Ni conc. 0.8-1g/l·Triethanolamine 40g/l·Room temperature Current density 6-10A/dm₂.

Pulmonary carcinosarcoma is an exceedingly uncommon malignant tumor with less than 100 cases reported to date. Carcinosarcoma of the lung, histologically, consists of intermingling elements of carcinoma (usually squamous cell type) and sarcoma (usually spildle cell type). We experienced a pulmonary carcinosarcoma case of 76-year-old man smoker with hypertrophic osteoarthropathy. The tumor, 12 × 8 × 8 cm sized, was located in the lower lobe of the left lung without endobronchial invasion, Lightmicroscopically, the tumor is composed of an area of tubular structure of adenocarcinoma and spindle cells of sarcoma. In immunohistochemical stain, the tumor consists of tubular structure that reveal positive for cytokeratin and the spindle cells for vimentin. So we report this case of carcinosarcoma of the lung with a literature review.

The extraction characteristic and stoichiometric relation for the solvent extraction of indium from acid solution was studied with D2EHPA(di-2-ethylhexyl phosphoric acid). The results showed that the extraction efficiency of indium increased with increasing pH of solution and D2EHPA concentration at the same pH condition. Also the extraction aspect and efficiency of indium in the HCI solution were similar to that in the sulfuric acid solution. The presence of SO^(2-)₄ and NO₃ would not affect the extraction of indium while Cl^- caused considerably the lowering of the indium extraction resulting from the formation of ligand complexes between Cl^- and indium in the solution. Generally, the optimum conditions for the extraction of indium appeared to be above 0.36M/L [R₂H₂] of D2EHPA and pH 0. On the other hand, the indium was extracted by non-solvated form like [InR₃] with D2EHPA and the extracted species were not associated with each other. The extraction relation would be as follows : [In^(3+)]_(aq) + 3/2[R₂H₂]_(org) = [InR₃]_(org) + 3[H^+]_(aq). The equilibrium constant for the reaction was found to be 12.531.

Intensity-modulated radiation therapy (IMRT) is believed to be one of the best radiation treatment techniques. IMRT is able to deliver fatal doses of radiation to the tumor region with minimal exposure of critical organs, It is essential to have a comprehensive quality assurance program to assure precision and accuracy in treatment, due to the character of IMRT. We applied quality assurance technique to the Eclipse treatment planning system and sought to determine its effectiveness in patient treatment planning. An acrylic phantom, film, and an ionization chamber were used in this study.
