This study was performed to evaluate the ultrasonographic findings of ethylene glycol intoxication. Ten healthy mongrel dogs which was administered with ethylene glycol, were evaluated in terms of clinical findings, hematological findings, blood chemistry, and ultrasonographic and histopathological findings of kidney. The results obtained through these experiment could be summarized as follows : 1. Typical clinical symptoms such as vomiting, initial apprehension, depression, thirst, dehydration, tremor, anorexia, hematuria, anuria, weakness, weight loss, flaccid paralysis, tachypnea, coma, and death, were revealed after administration of ethylene glycol. 2. Special symptom of bloody diarrhea was occurred by administration of ethylene glycol. 3. After administration of ethylene glycol, PCV was decreased continuously(p<0.01), and total leukocyte count was increased gradually, revealed the highest value at day 5 and thereafter decreased. 4. Remarkable changes of ultrasonographic findings such as high echo intensity of renal parenchyma and emergence of halo in corticomedullary junction, were revealed after administration of ethylene glycol. Early(hour 8) enlargement and late(day 3) enlargement were observed in kidney(p<0.01). Especially, late enlargement was observed concurrently with the elevation of BUN and creatinine values. 5. Calcium oxalate crystals, metabolites of ethylene glycol, were observed in histopathologic findings of kidney. Also, degeneration and necrotic exfoliation of epithelial cells were recognized in addtion to swelling of renal tubules.

2 Cases of nephrotomy for removal of calculi in dog were referred to veterinary teaching hospital of Konkuk University. In case 1, a 5 year-old, castrated male Yorkshire Terrier dog was referred because of intermittent hematuria, pain in urination for one month. Hematologic and chemical examination showed mild increased BUN and CPK. Radiographic findings revealed radiopaque materials in the urinary bladder, urethra, and left kidney. Retrograde hydropropulsion was performed to move the calculi into the bladder, and cystotomy was done to remove calculi. Nephrotomy was performed to removal of the calculi from the left renal pelvis and calyx. After operation renal function were recovered and preserved. In case 2, a 5 year-old, neutral female Schnauzer dog was referred because of persistant vomiting, anorexia, and celialgia for 20 days. Hematologic and chemical examination showed stress leucogram, moderate azotemia, hypercalcemia, hyperphosphatemia, and increased ALP. Radiographic findings revealed enlargement of the left kidney and radiopaque materials in the both of the kidneys. On excretory urography, left kidney was no pyelogram. On ultrasonography, renal tissue was very thin and distended renal pelvis appeared. Nephrectomy of nonfunctional left kidney and nephrotomy for removal of calculi from the right renal pelvis and calyx were done. One week after operation, renal and hepatic functions were recovered. So, in cases of renal calculi, it is necessary that renal calculi are extracted actively as far as the patient's body condition endurable.

Renal venous thrombosis (RVT) in neonatal period is a rare disease and usually complicated to clinical situations with reduced renal blood flow and hypercoagulability ; like acute blood loss, sepsis, shock, and birth asphyxia. RVT should be suspected in sick babies with hematuria, anemia, thrombocytopenia, enlarged kidney and acute renal failure. And the diagnosis can be confirmed by renal ultrasonography. We report two cases of neonatal renal venous thrombosis with review of literatures. One case, associated with E. coli sepsis, recovered completely, and the other, follwed respiratory distress in the neonate, revealed permanent renal functional impairment.

소아들의 여러 신장 질환 특히 만성신장병은 초기에는 뚜렷한 증세나 징후를 나타내지 않고 단독 단백뇨 또는 현미경적 혈뇨로만 나타나는 경우가 많다. 이런 신장 질환을 발견하기 위하여 소변검사는 여러 장단점에도 불구하고 간단하고 비용이 적게 드는 검사로서 선별검사에 이용하게 되었다. 우리나라에서는 신장 질환의 조기 발견을 위한 학교 집단소변검사가 1998년에 개정된 학교신체검사규칙에 근거하여 전체 초 중 고등학생을 대상으로 실시되었다. 그 이후에 많은 연구와 보고들이 학교 집단소변검사가 만성신질환의 조기 발견에 유용할 것이라고 하였지만 아직도 여기에 대한 이견이 있을 뿐만 아니라 비용 효과 등에 대하여서도 충분한 의견 일치를 얻지 못하였기에 코호트 연구 등의 장기적인 관찰적 역학 연구가 반드시 필요하다. 이를 위하여서는 신장학자들의 지속적인 연구뿐만 아니라 제도 개선 및 개발들이 반드시 동반되어야 할 것이다.

A 12-years-old Maltese (castrated male) dog with jaundice and purulent discharge from the shoulder was referred to the Veterinary Medical Teaching Hospital of Chungnam National University. A physical and laboratory examination revealed that the mucosa of the conjunctiva and the sclera were icteric, and the liver functional enzyme level and the total bilirubin level were increased. Duodenal caudal deviation caused by suspected masses in diameter of about 2 cm was shown by radiographic and ultrasonographic examinations. Using fine needle aspiration (FNA) and computed tomography (CT), the dog was diagnosed with alimentary lymphoma. The dog was treated with chemotherapy. Hematuria was discovered and dysuria occurred because of sterile hemorrhagic cystitis, which is a unique complication resulting from the use of cyclophosphamide.

A case of multicentric high grade T cell lymphoma is reported in a 5-year-old male Maltese dog with generalized lymphadenopathy. The dog showed depression, anorexia, blindness, jaundice, arrhythmia, and hematuria for 8 months. Complete blood count and chemistry profile revealed anemia and increased alanine transferase, alkaline phosphatase, total bilirubin, and total cholesterol. Grossly, most of lymph nodes, spleen, and liver were enlarged and neoplastic masses were occupied in these tissues. Histologically, massive accumulation of small noncleaved neoplastic lymphocytes with high mitotic figures was observed in all lymph nodes and spleen. Infiltration of neoplastic lymphocytes was also noted in the lung, liver, kidney, eye, skin, muscle, and bone marrow of femur. Immunohistochemistry revealed that tumor cells were CD3-positive and but CD79a-negative, consistent with T-cell lineage. In our best knowledge, this is the first report of multicentric lymphoma clarified the origin of tumor cells in Korea.

A 5-year-old female lion-head rabbit weighing 2 kg was brought to a local animal hospital with hematuria. Radiography showed a mass in the uterus, which was removed by ovariohysterectomy. Macroscopic examination showed several masses in both uterine horns. These masses, which invaded the deep uterine walls, were firm to the touch, and their cut surfaces were greyish-white in color. Histopathologically, these masses were nonencapsulated and were composed of spindle cells arranged in cellular, large interlacing bundles or streams. The tumor cells had elongate nuclei with prominent nucleoli, granular chromatin and eosinophilic cytoplasm. Moderate anisocytosis and anisokaryosis were observed. Severe and extensive inflammation and necrosis were present within the masses. Immunohistochemically, the neoplastic cells were positive for vimentin, desmin, and α-smooth muscle actin, but negative for cytokeratin. These uterine masses were diagnosed as leiomyosarcoma. To our knowledge, this is the first report of a uterine leiomyosarcoma in the rabbit in Korea.

A diffuse alveolar hemorrhage is a rare manifestation in microscopic polyangiitis. Recently we experienced a case of diffuse alveolar hemorrhage associated with microscopic polyangiitis, which was diagnosed with the typical clinical manifestations, ANCA and a renal biopsy. A 71 year old female was admitted complaining of coughing and dyspnea. A chest X-ray, HRCT and BAL revealed a diffuse alveolar hemorrhage. A diffuse alveolar hemorrhage was noted during a bronchoscopy. She also had proteinuria, microscopic hematuria and mild azotemia. The renal biopsy showed necrotic glomerulonephritis without immune complex deposits or granuloma. Under the diagnosis of microscopic polyangiitis, she was treated with steroid pulse therapy, and prednisolone with cyclophosphamide subsequently. She showed marked improvement in the clinical manifestations.

About 8 year-old castrated male Yorkshire terrier was presented for evaluation of dysuria, stranguria, hemtauria, and pollakiuria. On history taking, dysuria first was observed three months ago and these signs were waxed and waned. Physical examination revealed mild left perineal swelling. On routine laboratory examination, no significant findings were identified. Positive contrast urogram identified peritoneal herniation of urinary bladder. Urinalysis showed proteinuria and hematuria. Urine sediment revealed epithelial cells, white blood cells and rod-shaped bacteria. Pseudomonas aeroginosa was isolated from urine obtained through cystocentesis, and had resistance against fourteen antibiotics. Cystitis caused by P. aeruginosa concurrent with cystolithiasis and perineal hernia was diagnosed. Cystotomy, herniorrhaphy and EDTA-Tris solution lavage of bladder were performed. The patient was recovered to normal condition 2 days after treatment. Two weeks later, bacterial culture of urine was negative and any abnormality in ultrasonogram and urinalysis was not observed except calcium oxalate dihydrate crystals.
