Pilomatricoma was histopathologically diagnosed in a 2.5-year-old male Alaskan malamute. The patient was referred to Chungnam National University, Veterinary Medical Teaching Hospital with solitary, firm and well-circumscribed mass at shoulder. Grossly, the mass was dome shaped to tumor like and 10 x 8 x 5㎝ in size. Some lesions had gritty or bony consistency and was chalky when sectioned Histopathologic feature included mumerous clusters of tightly arranged, basaloid cells with evenly distributed chromatin and ghost cells were characterized by a central unstained zone. The ghost cells often become calcified and osseous metaplasia was also present.
Purpose : The purpose of this study was to evaluate the effect of nutritional support with enteral liquid supplement in cancer patients receving chemotherapy for possible benefit in nutritional, immunologic and golbal function of patients. Patients and Methods : From October 1995 to February 1997, 30 advanced cancer patients receving chemotherapy were divided two roups. The Nycare group, in addition to normal diet, Nucare^R enteral supplement was given for 1week right after chemotherapy for the duration of 2 chemotherapy cycles. Control group received only normal diet without parenteral fluid supplement for 2 chemotherapy cycles. Results : Median ages were 53 end 56 years for Nucare group and Contrl group respectively. Performance scores was less than 2 by ECOG scale. All patients were stage Ⅲ or Ⅳ. The physical parameters, such as weight, arm muscle circumference(AMC) and triceps skin fold(TSF) were decreased in both groups after 2 cycles of anticancer therapy. but it was less severe in Nucare group(p<0.05). Serum transferrin was maintained in mild deficit state in Nucare group, whereas it aggravated form mild to moderate deficit in Control group(p<0.05). Serum albumin level increased in Nucare group without statistical significance. but it decreased from normal to mild deficit in Control group. Serum total protein did not change significantly in Nucare group. but in Control group, serum total protein was decreased from 7.24±0.9 to 6.52±0.5(P<0.05). Total lymphocyte count did not change significantly in both groups. Conclusion : This study shows that the nutritional support with Nucare^R was effective in the prevention of nutritional deficit status in patients receving a nticancer chemotherapy.

Osteosarcoma is a primary malignant tumor arising most often in the long bone, but rare in jaw bone. Especially osteogenic sarcoma of the mandible is a rare tumor, comprising less than 0.5% of all head and neck tumors. Osteosarcoma occurs cheifly in young persons, and presenting very survival rates. Histopathologically this tumor can be classified three types, osteoblastic, fibroblastic, chondroblastic and classified from low grade to high grade by anaplasia or mitosis of the tumor cells. Sometimes, the exact diagnosis of osteosarcoma is difficult especially in low grade osteosarcoma, even if clinical or radiographical findings suggest to osteosarcoma. So suspcious to malignant bone tumor in clinical or radiological findings, biopsy should be taked from deep portion and multiple area, and sharing the patient history and radiographs with pathologist will assist in the development of the diagnosis. We report a case of low grade osteosarcoma on the mandible initially difficulty in accurate diagnosis. The patient visited our hospital for routine dental treatment but radiographic findings displayed ill-defined radiolucency with osteoid formation on the mandible. Final diagnosis was difficulty in initial biopsy but subsequent biopsy taked from deep portion presented infiltrative growth and mitosis of the tumor cell in some area with small osteoid bone formation, so we could reach final diagnosis as low grade sarcoma. We treated this patient with bloc resection of the mandible and immediate reconstruction with iliac corticocancellous block.
Non-Hodgkin's 림프종의 약 40%는 결절외(extranodal) 림프종으로 대개 위장관에서 발생하며 이들 중 점막 연관 림프조직(mucosa-associated lymphoid tissue: MALT)에서 기원한 림프종은 MALT 림프종으로 분류된다. 위 외의 부위에서 원발성으로 발생하는 MALT 림프종은 매우 드물지만 실제 거의 모든 신체 장기에 발생하는 것으로 알려져 있는데, 가장 흔한 부위인 위 외에도 폐, 갑상선, 침샘, 눈물샘에 발생하고, 드물게 안구, 유방, 방광, 신장, 흉선 등에도 보고된 바 있다. MALT 림프종은 오랜 기간동안 원격 전이하지 않고 국소 병변으로 남아 있는 특징이 있어 치료 방향 또한 국소 병변의 치료에 집중되며, 예후도 림프절 기원의 림프종에 비해 양호한 것으로 알려져 있다. 본 저자 등은 자궁 내막에 원발성으로 발생한 MALT 림프종 1예를 경험하였기에 문헌 고찰과 함께 이를 보고하고자 한다. Mucosa associated lymphoid tissue (MALT) lymphoma can rarely develop primarily in extranodal sites other than stomach which is the most common site for it. Other rare primary sites are small intestine, colorectum, esophagus, lung, thyroid, salivary gland, lacrymal gland, breast and skin. MALT lymphoma represents a distinct clinicopathologic features: it is usually localized to their original site for a long time and shows much more favorable prognosis than lymphoma at other site, but some MALT lymphoma can arise simultaneously or successively in different organ or give rise to another MALT lymphoma of other organ and can be multifocally disseminated or recurred. We report a very rare case of high grade B-cell lymphoma of mucosa associated lymphoid tissue (MALT) of the uterine endometrium, which was confirmed by immunohistochemical assay.
목 적: 뇌사 공여자로부터 적출된 두개의 신장을 하나는 MMF(연구군)에 다른 하나는 AZA(대조군)에게 이식하여 공여자 차이로 인한 영향을 최소화 하여 두 약제가 신이식 후 초기 급성거부반응과 이식신 생존율에 미치는 영향을 비교 분석하고자 하였다. 방 법 : 1998년 4월부터 2000년 1월까지 성균관의대 삼성서울병원에서 시행된 신장이식 중 공여자의 양측 신장(34쌍)이 제공된 68예의 사체 신이식을 대상으로 각 쌍을 MMF군(34예)과AZA군(34예)으로 무작위 배정을 하였고 면역억제제는 3제요법을 시행하여, MMF군은 Cyclosporine,MMF, Prednisolone을 AZA군은 Cyclosporine, AZA, Prednisolone을 투여 하였다. 두 군간의 6개월 이내의 급성 거부반응의 발생률과 CMV 감염 발생률 그리고 1년 이식신의 생존율 등을 전향적인 방법에 의해 비교하였다. 결 과: MMF군과 AZA군 간에 성별, HLA 부적합, 냉무혈시간, 몸무게 등의 유의한 차이는 없었다. 급성 거부반응 발생 또는 치료실패는 각각 12예(35.3%)와 11예(32.4%)로 두 군간에 유의한 차이가 없었고(p>0.05), 1년 이식신의 생존율은 각각 91.2%, 97.1%였고 CMV 감염은 각각 1예와 3예로 차이를 보였으나 통계적 의미는 없었다. 결 론: MMF와 AZA, 두 신이식 군에서 약제로 인한 급성 거부반응 발생률의 차이와 이식신 생존율의 차이는 없었다. 이는 기존의 보고들과는 다른 결과로 사체신이식일 경우 공여자의요인이 신장이식의 결과에 많은 영향을 미친다는 것을 의미한다. 그러므로 사체신이식을 통한 비교 임상 시험을 시행할 때는 기존의 연구들에서 제시한 공여자 인자 외 다른 공여자 인자들에 대한 충분한 고려가 있어야 하겠다. Objective : In order to evaluate how immunosuppressive agents such as MMF and AZA would influence on the outcome of the graft kidney, we analyzed the incidence of acute rejection episodes and one year graft survival rate after minimizing influences of donor factors by grafting the same cadaveric donor kidney. Methods : From April, 1998 to January, 2000, sixty eight patients grafted by 34 cadaver donors were enrolled in our study. From the same donor, one was randomly assigned to the MMF group(n=34) who were treated with cyclosporine, MMF, prednisolone while the other kidney was assigned to the AZA group(n=34) with cyclosporine, AZA, prednisolone. We analyzed the incidence of acute rejection episodes and CMV infection within the first 6 months of renal transplantation and one year graft survival rate was studied prospectively. Results : There were no significant differences in sex, HLA mismatch, cold ischemic time, and patients' weight between two group. Acute rejection or treatment failure occurred in 35.3% in the MMF group by 6 months after transplant, compared with 32.4% in the AZA group without statistic significance(12/34 vs. 11/34, p>0.05). One year graft survival rate was 91.2% and 97.1%, respectively, and CMV infection was documented in 4 patients(1/34 vs. 3/34, p>0.05). Conclusion : There were no significant differences in the incidence of acute rejection episodes and one year graft survival rate between two groups. In contrast, previous studies showed that MMF could have lowered the incidence of acute rejection episodes and improved graft survival rate. This discrepancy in results might be explained that donor factors were important to cadaveric renal transplantation. Thus, we suggest that the influences of donor factors should be considered in further clinical study of cadaveric renal trans-plantation.
The height of buildings define the skyline of cities, and in recent years, building height control have been approached from urban design aspect to bring about harmonious townscape as well as provide identity of city. Yet in Korea, the building height control has remained based on the width of the road they face. This has resulted in many problems such as skyline control, high density developments in outlying areas, land-use problems and lack of city identity. This research examines the existing height control system, the problems inherent in it and reviews building height control in advanced industrialized countries. The paper examines various urban planning as well as site specific considerations in resolving the problems in the building height control system currently in use, and introduces a new direction in building height control based on the street block.
Pain modification is an important part of traditional acupuncture therapies. However, the idea of using acupuncture to alleviate pain has been greatly expanded in the last four decades. It has reached the level that acupuncture may be used as a substitute for conventional anesthesia. Surgical analgesia can be produced by methods involving peripheral or central stimulation, such as Acupuncture Analgesia (AA). The most common method is Electro-Acupuncture Analgesia (EAA), using a special electrostimulator attached to needles in acupuncture points. The major advantages of AA or EAA are its safety in high-risk patients and excellent post-operative pain relief, freedom from complications and enhanced healing which follows surgery under AA. The major disadvantages are the long induction period (10-40 minutes) and variable degrees of analgesia even in skilled hands. The mechanisms of AA involve stimulation of peripheral sensory nerve, spinal cord and supraspinal areas (thalamus, midbrain and hypothalamus). AA can be used effectively in dog. The method has its advantages and disadvantages.
