Routine urinalysis is a simple, economical, and useful test that facilitates the detection of urinary system diseases and monitoring of renal disease progression. It consists of 4 parts of specimen evaluation, gross examination, a dipstick urinalysis, and a sediment microscopic urinalysis. Urine specimens should first be evaluated in terms of acceptability, and thereafter, the gross appearance is examined for color, turbidity, and odor. In particular, a dipstick urinalysis is an easy and rapid test that provides information on the multiple physicochemical properties of the urine sample. Moreover, although a sediment microscopic urinalysis is time-consuming, it provides information on the cells, microorganisms, casts, and crystals. In the present report, the clinical significance of the routine urinalysis and the problems concerning interpretation are summarized.

The gross appearance, cellular constituents, and quality of mucin clot of synovial fluid from the normal tibiotarsal joints of 57 healthy Korean cattle were investigated. The results obtained were summarized as followings. 1. The gross appearance of the synovial fluid were quite clear without any minute particles of flocculent, colourless (78.95%) or slightly yellowish (21.05%), and it did not coagulate within the 24 hours after sampling. 2. The mean number of leucocytes for the entire group was $127.68{\pm}13.84/mm^3$ (SE) with a range of 0 to $627/mm^3$ for individual samples. In the total cell count no significance among the investigated age and sex categories was found. 3. The mean differential values for the groups ware: neutrophil, $9.36{\pm}1.67%$; lymphocyte, $57.66{\pm}8.34%$; monocyte, $24.70{\pm}2.22%$; eosinophil, $1.45{\pm}0.27%$; and macrophage, $5.83{\pm}1.13%$. No basophils were observed in stained smears of synovial fluid. 4. Normal mucin clot quality was recorded for 94.7% of the animals, but 5.3% were observed to have fair mucin clot quality. Quality of mucin clot was approximately equal for bulls, cows, and calves.

목 적: 악성 종양과 연관된 흉막삼출에서 혈액상을 보이는 빈도를 확인하고 혈액상 여부와 세포진 검사나 흉막조직 검사의 양성률 그리고 흉막액 CEA 양성률과의 연관 관계를 확인해 보고자 하였다. 또한 일반적으로 흉막액 CEA의 증가는 세포진 양성률과 밀접한 연관관계를 보인다고 하는데, 이에 대한 의미를 재조명하고자 하였다. 방 법: 1995년 3월부터 1996년 12월까지 연세대학교 의과 대학 세브란스 병원에서 악성 종양으로 진단된 환자중 흉막삼출이 발생한 98예를 대상으로 흉막액의 통상검사(pH, cell count, glucose, protein, LDH)와 함께 흉막액의 외견, 적혈구 수, CEA, 그리고 세포 조직학적 검사를 시행하였다. 결 과: 악성 종양과 연관된 흉막삼출의 44.9%에서 혈액상이었고 55.1%에서 장액상으로 나타났다. 흉막액의 적혈구 수가 $100,000/mm^3$ 이상 증가된 경우 흉막액 세포진 검사의 양성률은 42.8%였으며 흉막액의 적혈구수와 흉막액 세포진 검사의 양성률 그리고 CEA 양성률 등의 상호간에 연관관계는 없었다. 세포조직검사장 확진된 악성 흉막삼출의 경우 흉막액 CEA는 72.7%에서 10ng/ml 이상으로 증가된 소견을 보였고, 흉막액 CEA가 10ng/ml 이상으로 증가된 경우 새포조직검사의 양성률은 58.2%였다. 종양 진단후 흉막액이 발현되기까지의 기간과 흉막액 세포진 검사의 양성률, 흉막액 CEA의 양성률, 그리고 흉막액 적혈구수 등의 상호간에 연관관계를 발견할 수 없었다. 결 론: 소견을 악성 종양과 연관된 흉막삼출의 44.9%에서 혈액상보였으며 흉막액내 적혈구 수의 증가와 세포조직학적 검사의 양성률이나 CEA의 양성률간에 유의한 상관관계는 없었다. 흉막액 CEA의 측정은 세포조직학적인 양성률과 일치하지는 않았지만 일부 비종양성 흉막삼출에 의한 증가를 임상적으로 배제하면 흉막생검, 세포진 검사와 함께, 악성 흉막삼출의 진단적 접근에서 보조적인 역할을 감당할 수 있을 것으로 생각된다.

The ratio of the aged population over 65 in Korea comprises 5.7% of the total population in 1995, and 7.1% in 2001, and it is expected that it will be 14% in year 2023. Also, owing to the appearance of various layers of the aged, it is necessary to prepare various programs and facilities for the aged who are healthy and economically capable in order for them to spend their life in an abundant and rewarded way. Andthere is a rising necessity not only to recognize the value of existence for the existing elderly welfare facilities but to prepare new elderly welfare facilities considering comprehensive elderly welfare as well. Especially, even though elderly welfare centers continue to provide for the aged both in a low-income class and a common class various service programs and activity programs, there still is a poor structure in terms of spatial dimension in detail to comply the service. Accordingly, we believe that it is necessary to have a comparative study on elderly welfare centers in Japan as elderly welfare facility that advances about 30 years ahead. For this purpose, this study compared the spatial structures of application programs according to facility regulations and their gross spatial classification focusing on elderly welfare centers in Japan and those of Korea. Based on this, this study intends to present basic materials for interior space planning when establishing elderly welfare centers founded on space dimension and structure along with the gross space in elderly welfare centers in Korea in the future.

본 연구에서는 갱년기 완화 연구에 앞서 처치 대상자를 폐경 이후로 한정하여 난소절제를 통해 폐경을 유도한 암컷 흰쥐를 대상으로 효모 가수분해물의 안전성 평가를 하였다. 효모 가수분해물을 8주 동안 아급성 처치한 후 관찰한 결과 갱년기 모델 쥐에서도 건강한 쥐와 마찬가지로 이전 연구와 같이 효모 가수분해물은 체중, 식이 섭취를 비롯해 임상적 소견과 혈액 생화학적 분석, 그리고 장기 무게 및 조직 병리학적 분석에서 안전한 것으로 평가되었다. 이에 효모 가수분해물은 폐경기 동물 모델에서 아급성으로 처치 시 독성을 일으키지 않는 것으로 생각된다.

Background Radiation-induced skin injury is a dose-limiting complication of radiotherapy. To investigate this problem and to develop a framework for making decisions on treatment and dose prescription, a murine model of radiation-induced skin injury was developed. Methods The dorsal skin of the mice was isolated, and irradiation was applied at single doses of 15, 30, and 50 Gy. The mice were followed for 12 weeks with serial photography and laser Doppler analysis. Sequential skin biopsy samples were obtained and subjected to a histological analysis, immunostaining against transforming growth factor beta (TGF-${\beta}$), and Western blotting with Wnt-3 and ${\beta}$-catenin. Increases in the levels of TGF-${\beta}$, Wnt, and ${\beta}$-catenin were detected after irradiation. Results All tested radiation doses caused progressive dermal thickening and fibrosis. The cause of this process, however, may not be radiation alone, as the natural course of wound healing may elicit a similar response. The latent appearance of molecular and histological markers that induce fibrosis in the 15 Gy group without causing apparent gross skin injuries indicates that 15 Gy is an appropriate dose for characterizing the effects of chronic irradiation alone. Thus, this model best mimics the patterns of injury that occur in human subjects. Conclusions This animal model can be used to elucidate the gross and molecular changes that occur in radiation-induced skin injury and provides an effective platform for studying this adverse effect without complicating the process of wound healing.

The use of human vessels at the beginning of microsurgery training is highly recommended. But vessels with the appropriate length for training are not often obtained. Whether these vessels may be reused for training has not been reported. Accordingly, we harvested vessels from discarded tissues in lymph node dissection and demonstrated that vascular anastomosis training using the same human vessels several times is possible by placing the vessels in a freezer and defrosting them with hot water. Vascular walls can be stored for microsurgical training until about 4 years after harvest, as shown in the gross appearance and histologic findings of our preserved vessels. We recommend the technique presented here for the long-term reuse of human vessels for microsurgery training that closely resembles real procedures.

Objectives : In order to investigate the toxicity of rats after oral administration of Eumcheonyijin-tang extract. Methods : The experimental animals were subdivided into control, short term administration group, and long term administration group. With changes of gross appearance, the histological changes of liver and kidney were observed. Blood chemical indexes used in this study were AST, ALT, total bilirubin, albumin, BUN and creatinine in serum. Results : In the long term administration group, histological changes were detected in the liver as centrolobular disposition of fatty tissue(adipose cell), and in serum test, AST, ALT increased at 21 days after administration group, serum total bilirubin were increased 21, 28 and 35 days after administration group. So it seems to induce toxicity. Kidneys of the long term administration group revealed histological changes : increasing of connective tissue and pyknosis of glomerulus cell were observed at 28 days after administration group, and in serum test, significant changes of albumin, BUN, and creatinine were admitted. So it seems to induce toxicity. Conclusions : In long term administration of Eumcheonyijin-tang toxicity was induced.

This benign canine histiocytoma was the most common single tumor type, followed lipoma, adenoma, soft tissue sarcoma, mast cell tumor and lymphosarcoma [2]. Canine cutaneous histiocytoma (CCH) most commonly occur as solitary lesions, head and pinnae are prefermential sites, that undergo spontaneous regression. The histologic appearance varies greatly, depending on the age of the lesion and the degree of necrosis and secondary inflammation. The age-specific incidence rate for CCH drops precipitously after 3 years, although histiocytomas occur in dogs of all ages [5]. Their etiology and pathogenesis are unknown. This case reports the gross and histopathological findings of canine cutaneous histiocytoma of observed in a young dog with localized calcification of lingual muscle. (omitted)
