An 11 kg, 7-year-old male pug dog with lameness and tumor of the 2-3rd interdigital portion of the right forelimb was referred to the Veterinary Medical Center of the Tokyo University. On the clinical examination findings, the tumor size was $3{\times}3 cm but alopecia and necrosis were not found. On the radiological findings, a bone lysis was found in the phalanges of digit II of the right forelimb but pulmonary metastasis was not found. The mass was removed with metacarpal bone. Histopathological examination of the mass revealed highly differentiated hemangiopericytoma. Two weeks after the operation, the dog was irradiated by orthovoltage radiation. The source of irradiation was 300 kV, 4mA, 4Gy and a focal spot to skin distance of 40 cm using 1.0 Cu, 1.0Al filter. The radiation therapy was performed twice a week for 5 weeks. The dog showed no recurrence and no metastasis. It was thought that the surgery and radiation therapy treatment was quite a useful method to treat a canine heman-giopericytoma.

A six-year-old, female Jin-do dog was referred for the recurrence of vaginal prolapse. Less than 7 months previously, the dog with the vaginal prolapse had been treated with hormone therapy because ultrasonography had identified a single follicular cyst in the left ovary. Three months after the first visit, the dog came into heat and the vaginal prolapse recurred. Ultrasonography showed multiple follicular cysts in both ovaries and radioimmunoassay detected a plasma estradiol-$17{\beta}$ concentration of 13.3 pg/ml. Treatment involved the repositioning of the vaginal prolapsed, ovariohysterectomy and the resection of the protruding tissue. The dog had been completely recovered two months later after the treatment.

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.

A 1-year-old castrated male Schnauzer dog was presented with heart murmur. Auscultation revealed systolic murmur located at the left heart base (grade 5/6). There were no remarkable findings on thoracic radiographs. Two-dimensional echocardiography revealed subaortic tunnel-like obstruction at the entrance to the left ventricular outflow tract. Anterior mitral valve leaflet appeared to be tethered to septum with minimal motion. Chordae tendineae was abnormally thickened. Color Doppler analysis revealed turbulent flow starting below the aortic valve. Mitral regurgitation was presented during systole. Spectral Doppler recordings revealed high velocity flow through the aorta and mitral regurgitation. Based on echocardiographic examination, the dog was diagnosed with subaortic stenosis concurrent with mitral dysplasia. The patient was medicated with ${\beta}-blocker$ and diuretics. It has been doing well without apparent clinical signs at 2 year after the diagnosis.

A 17-year-old neutered male Miniature Pinscher dog presented with a mass on the left side of the submandibular region. Fine needle aspiration revealed malignant epithelial cells from the salivary gland but no evidence of metastasis was found on radiography, ultrasonography, or computed tomography. The cervical mass was surgically resected, and the histopathological examination confirmed adenocarcinoma of the mandibular salivary gland. Seven months after the initial diagnosis, the dog is alive without any clinical signs. This report describes the clinical findings, cytology, diagnostic imaging, and histopathological characteristics of a mandibular salivary gland adenocarcinoma in a Miniature Pinscher dog.

A 6-year-old intact male Maltese dog presented with a history of blindness and ataxia. Neuro-ophthalmic examination revealed dilated pupils with absent pupillary light reflexes and menace response in both eyes. Mild peripapillary edema was noted in the fundus of the right eye. After magnetic resonance imaging, the dog was provisionally diagnosed with meningoencephalitis of unknown etiology. Follow-up funduscopy was performed to monitor the condition of the optic discs for three years. Despite of the treatment with prednisolone, the optic nerve progressed to atrophy and the dog couldn't restore vision.

A 39 kg, 7-year-old male Labrador Retriever dog with a 3-month history of epistaxis, sneezing, and nasal discharge was referred to the Veterinary Medical Center of the Tokyo University. On the plain X-ray and computed tomography (CT) of the head showed increased density of the soft tissue in the left nasal cavity and the tumor infiltrated to nasal septum. The tumor mass removed by rhinotomy. Histopathological examination of the mass revealed adenocarcinoma. Four weeks after the surgery, the radiation therapy was performed twice a week for f weeks. 4 months after surgery, the dog had a recurrence in nasal cavity and administered carboplatin 300 mg/$m^2$ twice. However, the tumor had no response to chemotherapy, additional surgery and additional radiation therapy, and the dog was euthanized at the owner's request. At necropsy, metastatic proliferation was confirmed in the lung, lymph nodes and nasal cavity.

We present the case of a 49-year-old man with a dog bite on his right index finger at the mid-phalanx level. The finger was severely contaminated by the dog bite but, the amputation margin was clean. We replantated the stump. His finger was recovered very successfully 12 months later. It is recommended that in these types of cases, replantation of the severed finger should proceed even if the amputated finger was contaminated by the dog bite, unless there are other factors that prevent replantation.

This report describes a dog infected with Hepatozoon canis, the first canine infection in the Republic of Korea. A 2-year-old intact male Maltese dog presented with anorexia and depression. Physical examinations revealed mild dehydration and hyperthermia ($39.8^{\circ}C$), and blood analysis showed pancytopenia. Diff-Quik staining of blood smear specimens showed the presence of ellipsoidal shaped structures (gamonts of H. canis) within a small number of neutrophils. Real-time PCR analysis using whole blood confirmed infection by H. canis. The clinical condition of the dog improved after symptomatic treatment and administration of doxycycline. Although a molecular epidemiologic survey in Korea showed H. canis infection of dogs, to our knowledge this is the first report of a dog infection in Korea molecularly shown to be H. canis.

A 2-year-old, female, American cocker spaniel dog presented for a 1-year history of severe ascites, exercise intolerance, tachypnea. At that time, she was in an emergency state. First, the dog was stabilized with oxygen therapy. A diagnosis of cardiac problem was made from history, auscultation, radiograph, ECG, and echocardiography. Jugular pulsation was palpated and a harsh, systolic murmur of tricuspid regurgitation was prominent at the right cardiac apex. Tricuspid valve dysplasia (TVD) was confirmed with echocardiography, accompanying enormous myocardial hypertrophy. The clinical signs had been improved for 8 months with careful therapy and periodic abdominocentesis, and ascites was well controlled. The situation, however, became worse quickly in a week because the client did not follow our management schedule. Finally, she died due to dyspnea and shock. After the spontaneous death, necropsy and histopathological examination were performed and when we opened the thorax, a significantly large heart was observed. On histopathological findings, grossly myocardium appeared pale initially, then progressed to yellow and white. Microscopically, there was an extensive hemorrhage along with loss of myocardial striations. Interstitial fibrosis and various degenerative alterations in myocytes were also present.
