A 1-year-old intact male Russian blue cat was admitted with a history of depression, partial anorexia, vomiting and dysuria. Through the blood analysis, ultrasonography and urinalysis, this cat was diagnosed as feline lower urinary tract disease with cystitis. Despite antibiotic therapy the cat showed stranguria and urinary catheterization were repeated several times. One week after, this patient appeared depression, hyperthermia and leukocytosis. Ultrasonography revealed a small amount of hypoechoic fluid around the right kidney and bacteria were found in the urine. The amount of the right subcapsular fluid was increased and bacteria were found in the fluid. On the excretory urography, leakage of contrast media were detected. The right kidney was surgically removed and suppurative fluid between the renal parenchyma and the thickened capsule was identified. After surgery, subcapsular abscess of the right kidney associated with pyelonephritis was confirmed histologically and this cat recovered without complications.

We report the case of a 14-year-old girl, diagnosed with atypical thrombotic microangiopathy (TMA). The patient presented with persistent fever, nausea, and newly developed peripheral edema. Her laboratory findings indicated chronic anemia with no evidence of hemolysis, thrombocytopenia, or elevated serum creatinine level. A few days after hospitalization, acute renal failure and fever worsened, and proteinuria developed. On day 40 of hospitalization, she experienced a generalized tonic seizure for 5 min, accompanied by renal hypertension. Brain magnetic resonance imaging revealed posterior reversible leukoencephalopathy syndrome. After steroid pulse therapy, a renal biopsy was performed because of delayed recovery from thrombocytopenia. The biopsy findings showed features of thrombotic microangiopathic hemolysis with fibrinoid change restricted. Current diagnostic criteria for TMA have focused on thrombotic thrombocytopenic purpura and hemolytic uremic syndrome, and diagnosis is based on the clinical presentation and etiology, with the consequence that idiopathic and atypical forms of TMA can be overlooked. Developing effective tools to diagnose TMA, such as studying levels of ADAMTS13 or testing for abnormalities in the complement system, will be the first step to improving patient outcomes.

Purpose: The purpose of this study was to examine the effect of absolute bed rest(ABR) on occurrence of bleeding, discomfort and back pain after kidney biopsy. Method: This study was the nonequivalent control group posttest design. The experimental group was allowed to stay in beds for 18 hour-bed rest(BR) after 6 hour-ABR while the control group was allowed to stay ABR for 24 hours. Results: No bleeding sign was showed for all the patients. Discomfort of voiding, eating, ABR in the control group appeared at a higher level. Three subjects in the control group needed nelaton catheterization, whereas no catheterization was required in the experimental group. There was no significant difference in back pain. However, the control group used more pain killer with significant difference. From these results. Conclusion: There was no significant correlation between ABR time and bleeding. On the other hand, the discomfort of the experimental group appeared at a lower level by reducing ABR time. Therefore, Reduction of ABR time after kidney biopsy would be more efficient way for patients.

Purpose : There have been numerous researches on urine ${\beta}_2$-microglobulin (${\beta}_2$-M) concerned with primary nephrotic syndrome and other glomerular diseases, but not much has been done in relation to pediatric age groups. Thus, our hospital decided to study the relations between the analysis of the test results we have conducted on pediatric patients and renal functions. Methods : Retrospective data analysis was done to 102 patients of ages 0 to 4 with renal diseases with symptoms such as hematuria, edema, and proteinuria who were admitted to Chung-Ang Yongsan Hospital and who participated in 24-hour urine and urine ${\beta}_2$-M excretion test between January of 2003 and January of 2006. Each disease was differentiated as independent variables, and the statistical difference of the results of urine ${\beta}_2$-M excretion of several groups of renal diseases was analyzed with student T-test by using test results as dependent variables. Results : Levels of urine ${\beta}_2$-M excretion of the 102 patients were as follows : 52 had primary nephrotic syndrome [MCNS (n=45, $72{\pm}45{\mu}g/g$ creatinine, ${\mu}g/g-Cr$), MPGN (n=3, $154{\pm}415{\mu}g/g-Cr$), FSGS (n=4, $188{\pm}46{\mu}g/-Cr$], six had APSGN ($93{\pm}404{\mu}g/g-Cr$), seven had IgA nephropathy ($3,414{\pm}106{\mu}g/g-Cr$), 9 had APN ($742{\pm}160{\mu}g/g-Cr$), 16 had cystitis ($179{\pm}168{\mu}g/g-Cr$), and 12 had HSP nephritis ($109{\pm}898{\mu}g/g-Cr$). IgA nephropathy (P<0.05) and APN (P<0.05) were significantly higher than in other renal diseases. Among primary nephrotic syndrome, FSGS with higher results of ${\beta}_2$-microglobulin test had longer treatment period (P<0.01) when compared to the lower groups, but no significant differences in Ccr, BUN, or Cr were observed. Conclusion : IgA nephropathy and APN groups showed significantly higher level of ${\beta}_2$-M excretion value than other groups. Although ${\beta}_2$-microglobulin value is not appropriate as an indicator of general renal function and pathology, it seems to be sufficient in the differential diagnosis of the UTI and in the prediction of the treat-ment period of nephrotic syndrome patients.

This study was performed to investigate the effect of pork on the cadmium detoxification in rats. Ninety male Sprague-Dawley rats weighing $125.3{\pm}1.4g$ were divided into five groups based on cadmium treatment(0, 25, 50, 100, 250ppm) and five levels of Cd in AIN-76 purified diet had been fed for 8 weeks. Cadmium was supplemented with a form of $CdCl_2$.. During following 8 weeks of intoxication, casein was replaced by pork and the effect of pork on cadmium- detoxification was compared with casein. After 8 weeks of Cd intake had resulted in apparent cadmium intoxication; reduced growth rate, enlarged kidney and testis, decreased hematocrit value and hemoglobin content in response to the supplemented Cd levels in the diets. Discontinuing cadmium feeding, the body weights were relieved. Pork-fed groups seemed to have higher body weight than casein-fed groups. Hemoglobin content and hematocrit value became normal range at detoxification stage. The weights of liver, kidney, and testis were decreased along with cadmium intake. However, organ weight ratio was not affected by cadmium. Cadmium accumulation in liver and kidney showed a tendency to increase in the cadmium-exposed groups. The levels of metallothionein were also significantly elevated in the tissues of liver in response to the levels of Cd supplemented(p<0.05). Cadmium concentration in kidney was two times higher than that in liver. Cadmium removal rate of liver was higher than that of kidney. Cadmium accumulation of the pork-fed group was lower than that of casein. Especially, the factors which affected the cadmium contents in kidney were $Cd^{***}$ and $Cd{\times}pork^{***}$. Metallothionein(MT) was increased with cadmium, and MT was not likely to be affected by pork. Based on the findings from gross lesion, rats fed 250ppm of Cd were externally emaciated, had exposed penis and observed atrophies of kidney and testis. Histopathological observation seemed that the liver of groups feeding Cd supplemented diets showed cellular degeneration and accumulation of eosinophilic materials in the capillaries. In kidney, rats fed Cd diets had shown tubular epithelium degeneration and lesions of basophilic materials, while testis were weakened in numbers of spermatid and sporadically enlarged of giant cells. But the rats administered cadmium-detoxified diet supplemented pork for 7 weeks were shown individually decreased lesions compared with the rats supplied with casein diet.

It is well understood that liposarcoma is most common in soft tissue sarcomas. It usually develop proximally in the extremities and most patients are older than 50 years. We report a case of huge liposarcoma which develop on left thigh of 67-year-old man. There was no evidence of metastasis and the tumor was successfully removed by marginal resection. Patient's height is 153 cm and weight is 43 kg, but the tumor's size is $34{\times}20{\times}9\;cm$ and weight is 2.82 kg. The Mass is severely huge in compare with patient's height and weight. But, There are few reports regarding the correlation between tumor-size and pathologic differentiation. Pathological examination reveals a well differentiated liposarcoma. The patient is still asymptomatic at 6-months follow up.

Renal epithelioid angiomyolipoma (EAML) is a rare variant of angiomyolipoma (AML), with a prominent epithelioid component. EAML usually presents as a large heterogeneous soft tissue lesion with intratumoral hemorrhage and variable necrosis or cystic changes. We present a case of multiloculated cystic renal EAML mimicking renal cell carcinoma in a 64-year-old female. Intracystic massive hemorrhage, hyperattenuating wall and septa on an unenhanced study, and enlarged intratumoral vessels can be helpful imaging features for distinguishing renal EAML from renal cell carcinoma.

The study was conducted to analyze the extent of students' creativity through the use of scaffolding composed of different kinds of experience in making insights on problem solving and to investigate the function of a new scaffolding type which is not used in accomplishing a phase of activity but in having an insight. The students' achievements in problem solving given the scaffolding for on-site experience were compared with those given the scaffolding using stories. Also, the extent of creativity of the first- and sixth- grade students using the two types of scaffolding were investigated as they carried out picture completion task from TTCT. The results of the study showed that the control groups not given the scaffolding in post-test did not advance in creativity but experimental groups given the scaffolding showed improvement in some subordinate elements after scaffolding. Moreover, scaffolding using stories were more effective in enhancing the students' creativity than the scaffolding using on-site experience.

Wegener's granulomatosis is a systemic vasculitis of the medium and small arteries, as well as of the venules, arterioles, and occasionally large arteries, and primarily involves the upper and lower respiratory tracts and the kidneys. Renal symptoms of Wegener's granulomatosis are indistinguishable from those of vasculitis such as Henoch-$Sch\ddot{o}nlein$ purpura and microscopic polyangiitis. This case, though initially diagnosed as Henoch-$Sch\ddot{o}nlein$ purpura, was confirmed as Wegener's granulomatosis from a lung biopsy fifteen years after the initial diagnosis. We report this case with a review of the literature.
