To consider the iliac fossa as the vascular anastomosis site of kidney transplantation for the short-term study of acute rejection in pigs. Twelve domestic pigs weighing 39~48 kg underwent heterotopic renal allgraft transplantation. The experimental animals were divided into 2 groups in terms of renal vascular anastomosis site; the external iliac artery and vein were used in iliac fossa model (n = 6), the abdominal aorta and the caudal vena cava inferior to the kidney were used in abdominal cavity model (n = 6). Renal function was evaluated by daily measurement of plasma creatinine and BUN concentrations. The experiments' health including postoperative complications was also assessed daily for 8 days after transplantation. After euthanazation gross and histopathologic analysis was performed. All six pigs in iliac fossa model developed neuropraxia and lameness of the ipsilateral pelvic limb. However, no necrosis was observed in any pigs. In the abdominal cavity model, durations of both the surgical operation and the vascular anastomosis were significantly longer than those in the iliac fossa model. Furthermore, ischemia injury of the transplanted kidney was increased in abdominal cavity model, which induced accelerated-acute immune response from day 4 after transplantation. Despite of pelvic limb complication, the iliac fossa model showed more advantages including not only less ischemia time related to easy vascular anastomosis, but also less immune response during the acute rejection period. The results indicate that the iliac fossa model may be appropriate to the study of acute rejection in porcine kidney transplantation.

Three dogs that had a history of abdominal distension were referred to the hospital. All were female with unilateral involvement. History and clinical signs were nonspecific. Abdominal radiographs demonstrated that the abdomen of all cases was filled with large masses. At laparotomy, all masses were kidney tumors with invasion around tissue. The tumors were soft, irregular, creamish and confined within the capsule. One case had liver metastasis. Another case was found to have adrenal gland metastasis. One case had caudal vena cava invasion. A ureteronephrectomy was performed unilaterally in all cases. In the microscopic appearances, all the tumors had malignant features with nuclear pleomorphism and amount of necrosis. Three cases were diagnosed as renal carcinomas.

An-11-year-old male Shih-tzu was admitted to emergency care unit of Haemaru Referral Animal Hospital with signs of dyspnea, anuria and depression. There were abnormalities on complete blood count and serum chemistry included leukocytosis with mild left shift, mild azotemia, and increased ALT activity. Fluid therapy(0.9% saline, 40 ml/hr) and antibiotics were immediately initiated. The patient began to vomit after 5 hours' rest and pale mucous membrane, bradycardia, and hypertension were noted. Abdominal ultrasonography revealed enlarged left adrenal gland and thrombus in caudal vena cava(CVC). Result of ACTH stimulation test was normal. Cytology of ultrasound-guided FNA smears showed numerous naked nuclei, which was suggestive of adrenal medullar tumor. Concentrations of 24 hour urine metanephrine and normetanephrine was moderately increased compared to those of a control dog. Adrenal mass was surgically removed, and biopsy of the CVC mass was obtained. After surgery the patient began to recover but the dog acutely developed cardiopulmonary arrest and died. On histopathology the adrenal mass and biopsy of the CVC mass were consistent with pheochromocytoma. On electron microscopic view norepinephrine specific granules were found in the cytoplasm of tumor cells.

Dirofilaria immitis, the causative agent of canine heartworm disease, inhabits mainly in the pulmonary arteries and the heart of dogs and cats, causing circulatory and respiratory disorders. Although diagnosis of the disease is based on the presence of microfilaria in the peripheral blood or of specific antigens released from the adult worms into the peripheral blood, the severity of the infection and the assessment of disease progression are based on the clinical signs and radiographic image analysis. We analysed 12 mixed-bred Jindo dogs naturally infected with Dirofilaria immitis without any clinical signs and compared the radiographic images of the heart and the lung with the number of adult worms at necropsy. The dorsoventral radiographs of 12 infected dogs revealed that the right caudal lobar pulmonary arteries (RCaLPA) were dialated in 66.7% of dogs, whereas the main pulmonary artery segment was enlarged in 50.3% of dogs. The cranial lobar pulmonary arteries (RCrLPA) were dilated or pruned in 33.3% of dogs. All dogs displayed the interstitial lung pattern, while the vertebral heart size (VHS) was of normal range. Although a range of 9 to 166 adult worms (av. 45.6) was found in the pulmonary arteries, in the heart or in the vena cava, no correlation with the radiographic findings and/or with the clinical signs was observed.

Two dogs referred to Veterinary Medical Center, Chungbuk National University diagnosed as multiple extrahepatic portosystemic shunt were reported. The first dog was a 20-month-old, 8 kg, male Cocker spaniel with history of peritoneal effusion, diarrhea, anorexia and stunted growth. The second dog was a 3-year-old, 13.4 kg, male Jindo with a history of severe depression. Hematologic examination of first dog revealed mild microcytosis and nonregenerative anemia. All of 2 cases, serum chemical values showed increase of serum ammonia, ALP, r-GTP and glucose. In survey radiography, microhepatia was apparent. In the color Doppler ultrasonographic examination, the first dog revealed a dilated tortuous vein communicating with caudal vena cava was observed near the left kidney and the second dog revealed numerous shunting vessels ventral to L5 and L6. Transcolonic portal scintigraphy of the first dog confirmed the presence of portosystemic shunt. In intraoperative jejunoportography, the first dog showed single congenital extrahepatic portosystemic shunt and multiple acquired extrahepatic portosystemic shunts. The second dog showed multiple acquired extrahepatic portosystemic shunts. In these dogs, the presence of congenital and acquried portosystemic shunts and histopathologic findings were considered to represent a combination of multiple extrahepatic portosystemic shunts and noncirrhotic portal hypertension or portal vein hypoplasia.

A 12-year-old Standard Poodle presented with intermittent weakness and occasional dyspnea at the Veterinary Medicine Teaching Hospital of Kangwon National University. A grade of 4 out of 6 systolic murmur with an irregular tachycardic rhythm was auscultated on both sides of the chest. Systolic blood pressure was 140 mmHg. Panting was noticed in the hospital, but there was no crackle sound. Blood analysis revealed mild increases in liver panel levels (alanine aminotransferase 149 [reference interval, 19-70] U/L; and alkaline phosphatase, 185 [reference interval, 15-127] U/L) and severe increases in cardiac biomarker levels (n-terminal pro-brain natriuretic peptide, 4169 [reference interval, 50-900] pmol/L; and cardiac troponin I, 0.22 [reference interval, 0.03-0.12] ng/mL). On electrocardiography, irregularly irregular supraventricular tachycardic rhythm with an f-wave and no distinct p-wave was observed. Generalized cardiomegaly with an enlarged right atrium and left ventricle was confirmed on thoracic radiography. Moreover, hepatomegaly and an enlarged caudal vena cava were observed. Echocardiographic evaluation revealed a fibromuscular diaphragm in the right ventricle. Because of the obstructive lesion in the right ventricle, the right atrium and ventricle were enlarged (right atrial area index, 38.82 cm²/m² [reference interval, 4.2-10.2 cm²/m²]; right ventricle end-diastolic area index, 14.152 cm²/m² [reference interval, 4.9-10.92 cm²/m²]). Accordingly, the patient was diagnosed with double-chambered right ventricle (DCRV). Pimobendan, furosemide, enalapril, diltiazem, and S-adenosylmethionine (SAMe) were prescribed, and all symptoms were relieved. DCRV is a right-sided congenital heart defect resembling pulmonic valve stenosis. If symptoms are not severe, medical therapy can be facilitated without surgery or the balloon dilation.
