We describe the case of a Jindo dog that presented with a 2-month history of an abscess-like mass on the skin of the left hip. The patient was initially diagnosed with a suspected insect bite and was treated with a topical dressing. After observing no improvements, surgical debridement was done to remove the abscess. Nine days after surgery, the patient started showing severe anorexia, vomiting, lethargy, and oliguria. Azotemia was detected, and the patient was diagnosed with acute kidney injury. Ultrasonography depicted an abdominal mass (4.6 × 7.5 cm) in the right ureter, and severe hydronephrosis in the right kidney. The patient was euthanatized. Results of the necropsy, histopathologic examination, and immunohistochemistry for tumor cells, confirmed that the patient had developed hydronephrosis and disseminated histiocytic sarcoma which had metastasized to the lungs. To the best of our knowledge, this is the first report of acute renal failure produced by ureter invasion and urinary tract obstruction resulting from the abdominal mass of disseminated histiocytic sarcoma in dogs.

Objective : Gypsum fibrosum has been traditionally used in treatment of febrile diseases and recently been shown to have anti-inflammatory effect. Chronic renal failure has a serious clinical symptoms including proteinuria, azotemia, anemia, and hyperlipidemia and has characteristic histopathological changes, glomerular hypertrophy, infiltration of inflammatory cells, and crescentic sclerosis, We investigated the effects of gypsum fibrosum on renal functional and histopathological disorder in chronic renal failure rat model induced 5/6 nephrectomy. Methods : Using Sprague-Dawley rats, CRF was induced by 5/6 nephrectomy. The rats were divided into 3 groups, normal, conrol, and gypsum administered orally with gypsum fibrosum 500mg/kg/day. Body weight, 24 hr proteinuria, hematologic analysis, and histological morphologic changes were followed up after 8 weeks. The glomerular macrophage/monocyte infiltration, $TGF-{\beta}_1$, type IV collagen, and angiotensin II type1 receptor($AT_1$) were evaluated by immunohistochemistry. Resuls : In the CRF control group, functional parameters and histopathologic changes clearly indicated the development of CRF. 24 hr proteinuria significantly increased in the CRF control group over the normal group, and serum creatinine level was lower in the gypsum group than in the control group, LDL-cholesterol was significantly lower in the gypsum group than in the control group. Morphological investigations showed a variety of characteristic features of CRF, glomerular hypertrophy, increasing cellular density of glomerulus, deposition of extra-cellular matrix, fibrotic change, and glomerular sclerosis in the control group, but in the gypsum group, these features diminished significantly. In observation of renal type IV collagen and $AT_1$ expression, positive area significantly increased in the control group over the normal group, and it significantly decreased in the gypsum group compared to the control group. Conclusions : Our findings suggest that gypsum fibrosum inhibits $AT_1$ and type IV collagen expression in renal tissues and attenuates progression of glomerulosclerosis and interstitial fibrosis in chronic renal failure rats, which lead to amelioration of renal function. From these results, we suggest that gypsum fibrosum may have renoprotective effects and could be a useful remedy agent for treating chronic renal failure.

We experienced 7 cases of patients who were performed $^{99m}Tc$-methylene diphosphonate bone scintigraphy for the evaluation of diseases they had. Their bone scintigrams showed incidental radionuclide uptake in the gastrointestinal tracts and they had no special symptom or sign attributable to the findings. Case 1 showed radionuclide uptake in the stomach and both lung and the patient had suffered from hypercalcemia and azotemia. Case 3 and case 6 showed diffuse radionuclide uptake in the stomach and intestinal tract. Others showed diffuse or regional radionuclide uptake in the intestinal tracts. Radionuclide uptake in the gastrointestinal tract by $^{99m}Tc$-methylene diphosphonate is caused by a certain pathologic lesion but also can be seen in the normal gastrointestinal tract. So, one who reads bone scintigrams should be alert for the pathologic lesion in the gastrointestinal tract although one must interpretate with the concept of this normal variations.

It has been demonstrated that vanadate causes nephrotoxicity. Vanadate inhibits renal sodium potassium adenosine triphosphatase (Na, K-ATPase) activity and this is more pronounced in injured renal tissues. Cardiac cyclic adenosine monophosphate (cAMP) is enhanced by vanadate, while increased cAMP suppresses Na, K-ATPase action in renal tubular cells. There are no in vivo data collectively demonstrating the effect of vanadate on renal cAMP levels; on the abundance of the alpha 1 isoform (${\alpha}_1$) of the Na, K-ATPase protein or its cellular localization; or on renal tissue injury. In this study, rats received a normal saline solution or vanadate (5 mg/kg BW) by intraperitoneal injection for 10 days. Levels of vanadium, cAMP, and malondialdehyde (MDA), a marker of lipid peroxidation were measured in renal tissues. Protein abundance and the localization of renal ${\alpha}_1-Na$, K-ATPase was determined by Western blot and immunohistochemistry, respectively. Renal tissue injury was examined by histological evaluation and renal function was assessed by blood biochemical parameters. Rats treated with vanadate had markedly increased vanadium levels in their plasma, urine, and renal tissues. Vanadate significantly induced renal cAMP and MDA accumulation, whereas the protein level of ${\alpha}_1-Na$, K-ATPase was suppressed. Vanadate caused renal damage, azotemia, hypokalemia, and hypophosphatemia. Fractional excretions of all studied electrolytes were increased with vanadate administration. These in vivo findings demonstrate that vanadate might suppress renal ${\alpha}_1-Na$, K-ATPase protein functionally by enhancing cAMP and structurally by augmenting lipid peroxidation.

The kidneys play a vital role in the maintenance of normal body fluid volumes and in the composition of the extracellular fluid compartments. There are normally more than 2 million functioning glomeruli that regulate total body water and solute concentrations. As renal failure progresses, there is a decrease in the number of functioning nephrons. Chronic renal failure(CRF) is the consequence of a multitude of diseases that cause permanent destruction of the nephron. Azotemia is an elevation in blood urea nitrogen(BUN) and serum creatinine levels subsequent to a decreased glomerular filtration rate(GFR), which results in uremia. This loss of renal function can cause functional and metabolic abnomalities of body. For this problem, oral & maxillofacial surgeons have demanded to routinely treat patients with CRF. However, there has not been a reported case of orthognathic surgery by bilateral sagittal split ramus osteotomy(BSSRO) in patients with CRF, which can cause multiple complications in healthy patients. We report developmental mechanism of complication associated with CRF and preop. and postop. care of orthognathic surgery by BSSRO in Cl III patient with severe chronic renal failure.

A 73-year-old, previously healthy man presented with nausea, vomiting, diarrhea, dry mouth and febrile sensation 3 hours after eating boiled wild mushrooms. After admission, he showed progressive severe respiratory distress, pancytopenia, azotemia, hypotension, hypoxemia and consolidation of the entire left lung on chest radiography. With a preliminary diagnosis of necrotizing pneumonia, he underwent left pneumonectomy in order to remove all necrotic lung tissue. Lung histology showed extensive hemorrhagic necrosis, massive inflammatory cell infiltration, prominent proliferation of young fibroblasts and the formation of an early-stage hyaline membrane along the alveolar wall. Despite aggressive treatment, including mechanical ventilation, continuous renal replacement therapy and administration of granulocyte colony stimulating factor and broad spectrum antibiotics, he died on hospitalization day 13. Subsequently, the mushroom was identified as Podostroma cornu-damae. This is the first case of a histological evidence of lung involvement by Podostroma cornu-damae poisoning in Korea.
