A 9-year old female Shih Tzu dog was presented to the Veterinary Medical Teaching Hospital of Seoul National University with a history of chronic intermittent anorexia and vomiting of 4-year duration. She visited 3 years ago with the same clinical signs but has not been treated regularly due to waxing-waning course. On the physical examination, no specific findings were found. CBC, serum chemistry, radiography, ACTH stimulation test, evaluation of serum T4 and TSH concentration were performed. Hypoadrenocorticism was diagnosed with the ACTH stimulation test. And then, secondary hypoadrenocorticism was diagnosed with ACTH stimulation test, pre-ACTH aldosterone concentration, endogenous ACTH concentration. As electrolyte concentrations were normal, glucocorticoid (0.15 mg/kg bid PO) alone was administered. She has recovered from the clinical signs and has been doing well. It is suggested that the differentiation of secondary hypoadrenocorticism from primary hypoadrenocorticism is important as the secondary hypoadrenocorticism occurs rarely and the symptoms are non-specific with normal electrolyte concentrations.

A 7-year-old, spayed female, Yorkshire terrier dog with polyuria/polydipsia (PU/PD), interdigital edema, pruritus and abdominal enlargement was referred to the Veterinary Medical Teaching Hospital of the present university. Pituitary-dependent hyperadrenocortisim (PDH) was diagnosed by clinical signs, physical examination, laboratory examination (complete blood count, serum chemistry, urinalysis, ACTH stimulation test and high dose dexamethasone suppression test) and diagnostic imaging (radiography, ultrasonography and computed tomography). Clinical signs were improved after trilostane treatment, and maintenance therapy with trilostane still continued after successful induction therapy. Trilostane can be used as an alternative to mitotane therapy in hyperadrenocortisim in dogs.

A two-month-old female Yorkshire terrier was referred to the Veterinary Teaching Hospital, College of Veterinary Medicine, Kyungpook national University. The patient was presented with a history of dyspnea, cough, exercise intolerance and abdominal distension, but she was appetence. In physical examination the puppy was coughed on slight tracheal compression. Rectal temperature, pulse and respiratory rate were normal, and grade 3/6 systolic murmur heard at the left heart base. The murmur was crescendo-decrescendo. Electrocardiography showed sinus arrhythmia, right-ventricular hypertrophy pattern, and right axis deviation. Thoracic radiography revealed cardiomegaly, bulging of the main pulmonary artery, and enlarged left side heart. Abdominal radiography revealed abdkominal distention. Echocardiography showed hypertrophy of right ventricle and turbulence in the pulmonary artery in parasternal oblique view. Subvalvular pulmonic stenosis was diagnosis based upon the clinical signs, physical examination, electrocardiography, radiography and echocardiography. We treated the patient with furosemide, enalapril and $\beta$-blocker. After the clinical signs of cough, abdominal distension and dyspnea were disappeared, she was on just $\beta$-blocker for prevention of occurrence of congestive heart failure. Now she was recovered her health, and she is not on any medication.

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 2-year-old female mixed dog(weighing 4.3 kg) was referred to the Veterinary Teaching Hospital, Kangwon National University, with primary complaints of exercise intolerance, nocturnal coughing and heart murmur. Diagnostic studies revealed bi-lateral holosystolic murmurs on phonocardiogram, over-riding aorta, pulmonic stenosis, ventricular septal defect, atrial septal defect, biventricular hypertrophy, and subaortic stenosis in diagnostic imaging studies. Based on the diagnostic findings, pentalogy of Fallot(POF) with subaortic stenosis(SAS) was tentatively diagnosed. This is the first case report of POF complicated with SAS in a dog in Korea.

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.

Dirofilaria immitis parasitizes mainly in the pulmonary arteries and in the heart of dogs and cats. The parasite is also of public health importance, because it often elicits nodules in the pulmonary parenchyma and in the subcutaneous tissues, or sometimes parasitize itself in the eyes of human. In this study, we investigated the prevalence of heartworm infection among 165 dogs on three breeding farms in the vicinity of Seoul, Korea. Of 165 dogs, 83 dogs (50.3%) were infected with the parasite, as revealed by an antigen-detecting test using the peripheral blood. Of these, 23 dogs (20.2%) contained microfilaria using the peripheral blood, which are potential source of transmission to uninfected animals and to humans in the endemic area. None of infected dogs showed any clinical signs associated with the disease. Since the three farms were located in the vicinity of Seoul, the unexpectedly high infection rate could imply that the possibility of exposure of both animals and humans living in the metropolitan Seoul area to the parasite is higher than in the other area of Korea.

A Persian chinchila (2 years old, intact female) and a Korean domestic shorthaired cat (3 months, intact male) were referred to the Veterinary Medical Teaching Hospital of Chungnam National University with tachypnea. The two cats were diagnosed as feline infectious peritonitis (FIP) by blood and blood chemical examination, radiographic examination, RT-PCR and electrophoresis analysis of pleural effusion. Thromboxane synthetase inhibitor (Ozagrel HCl, 5 mg/kg, twice a day) was administered to the Persian chinchila and Korean domestic shorthair for 13 days and 16 days, respectively. Pleural effusion disappeared after treatment with Ozagrel HCl. Further study is needed to establish a new application protocol of Ozagrel HCl for FIP cases.

A 10-year-9-month-old spayed female Shih Tzu was presented with ocular discharge and corneal opacity to Veterinary Medical Teaching Hospital of Seoul National University. Complete ophthalmic examination revealed bilateral keratoconjunctivitis sicca accompanied by the severe corneal neovascularization and edema in the right eye (OD). Ultrasound biomicroscopy incidentally showed an iridociliary mass located at 6~7 o'clock in the OD. No evidence of metastasis was observed on thoracic and abdominal radiography. Enucleation was selected and performed on the OD, considering the risk of metastasis or recurrence. Non-invasive and pigmented iridociliary adenoma was confirmed on histopathological evaluation.

A six-year-old intact female Bull Terrier dog (weighing 17 kg) was referred to the Veterinary Teaching Hospital with exercise intolerance and occasional syncope as the primary complaint. Diagnostic studies revealed a rare case of atrial flutter with complete heart block and aberrant ventricular activation from the ectopic focus, possibly due to idiopathic dilated cardiomyopathy. Although the dog was responded with cardiac medication for right-sided heart failure and anti-arrhythmic agent (dofetilide), the dog died suddenly of cardiac arrest after 11 months of treatment.
