김하정,박희명 한국임상수의학회 2015 한국임상수의학회지 Vol.32 No.6

A 7 year-old intact female black spotted and white hair Shih-tzu dog visited for screening of vital condition and was suspected multifocal alopecia on physical examination. On dermatologic examination, alopecia with patches on black spot area, generalized seborrhea sicca, and bacterial infection were detected. Additionally, melanin clumping in the hair shafts on the alopecic area was detected by microscopic examination. Based on the signalment and dermatologic examination, black hair follicular dysplasia was diagnosed. To our best knowledge, this the first case report of black hair follicular dysplasia in Shih-tzu.

권희정,최원진,이동국,데이비드탄,현창백 한국임상수의학회 2015 한국임상수의학회지 Vol.32 No.5

Peritoneal dialysis (PD) is a treatment for renal failure and acute poisoning, and uses the patient's peritoneum in the abdomen as a membrane across which fluids and dissolved substances are exchanged from the blood. In this study, we evaluated the therapeutic efficacy and complications of automated peritoneal dialyzer (APD) in dogs with renal failure. PD was performed in 10 dogs using a swan neck catheter (Neonatal, Coviden) and automatic APD. The efficacy for each dog was assessed by calculating urea reduction ratio (URR) and creatinine reduction ratio (CRR). Mean concentrations of pre-dialysis creatinine and blood urea (BUN) were 7.09 ± 3.84 and 145.8 ± 48.5, respectively. The mean number of peritoneal dialysis cycles applied was 6 ± 1 cycles. Peritoneal dialysis resulted in a significant decrease in BUN concentration in 7/10 dogs, while a significant decrease in creatinine concentration in 9/10 dogs. The mean of URR was higher than that of CRR (0.39 ± 0.16 vs 0.38 ± 0.13). The mean CRR and URR per dialysis cycles were 0.064 ± 0.023 and 0.065 ± 0.023, respectively. Complications found in this study were catheter occlusion, subcutaneous dialysate leakage, septic peritonitis, hypoalbuminemia and overhydration. This study found PD using a swan neck catheter and APD machine showed acceptable efficacy for successful peritoneal dialysis in dogs. However, close monitoring is required to minimize the risk of complication.

이인,이정우,최수영,한우석,이기자,이영원,최호정 한국임상수의학회 2015 한국임상수의학회지 Vol.32 No.2

Tei-index has been reported as one of reliable echocardiographic factors for evaluating cardiac function in human and small animals. In this study, Tei-index were measured and evaluated with other echocardiographic parameters in normal thirteen beagle dogs and thirty-one dogs with mitral valve degeneration. Normal range of Tei index with tissue Doppler obtained at septum and left ventricular free wall was 0.58 ± 0.07 and 0.60 ± 0.07, respectively. The values between septum and left ventricular free wall did not show significant difference. Tissue Doppler derived tei index showed better reproducibility and significantly lower values than the results obtained by pulsed wave Doppler. Tei index obtained in either method increased with the progression of clinical signs. Therefore, the increase of Tei index in dogs with mitral regurgitation is thought to be an useful factor reflecting left ventricular dysfunction.

Evaluation of Diuretic and Hemodynamic Effect of Extract from Akebia quinata Decaisne in Dogs

한숙희,김예원,현창백 한국임상수의학회 2012 한국임상수의학회지 Vol.29 No.3

Treatment for heart failure is directed to reduce atrial volume overload by diuretic agents, to lessen ventricular pressure overload by vasodilatory agents and to increase myocardial performance through inotropic agents. Of those cardiac therapeutics, diuretic agents are the most important to control heart failure in dogs, although long-term use often causes detrimental side-effects such as acute renal failure and electrolyte abnormalities. Thus, this study was designed to find a new diuretic agent from medicinal herbs which has better diuretic effect and less unfavorable complications in dogs. In a preliminary study performed with 5 normal healthy dogs, the extract from Akebia quinata Decaisne showed mild to moderate diuretic effect (0.3-0.5 potency of furosemide 2 mg/kg) and minimal changes in serum chemistry and electrolyte. Although the study population was not large enough and study period was not sufficient enough, this study found a good alternative diuretic agent which can replace or reduce the use of furosemide in dogs with heart failure.

황용현,김민경,박정현,진소영,박기태,이희천,이재훈 한국임상수의학회 2013 한국임상수의학회지 Vol.30 No.6

An eight-year-old, castrated male, Poodle dog was presented with a bite wound in the neck region. Clinical examination revealed non-ambulatory signs of tetraparesis with deep pain, and upper motor neuron changes in all limbs. Fractures of the transverse process of C1 and the dorsal spinous process of C2 were observed on the radiographs and the computed tomography (CT). Conservative therapy was performed for 1 week. However the neurological problems were not alleviated until 7 days after injury. The owners agreed to perform surgical stabilization. The surgical stabilization was performed 7 days after presentation. Ventral stabilization was performed with screws, K-wires and bone cement. The dog stood up independently after 4 weeks and was able to walk 6 weeks postoperatively. In this report we suggest that using combined stabilization techniques are effective for this type of cervical fracture in which the dorsal and ventral structures of the vertebra are severely disrupted.

The Exon 2 Deletion of the COMMD1 Causing Copper Toxicosis in Bedlington Terriers in Korea

김윤기,김소연,윤영민 한국임상수의학회 2015 한국임상수의학회지 Vol.32 No.1

This study was performed to survey prevalence of Copper metabolism domain containing 1 (COMMD1) mutation using molecular diagnostic method in a population of Bedlington terriers in Korea. COMMD1 gene (formerly MURR1) functions as a regulator of sodium transport and copper metabolism. The deletion of exon 2 of the COMMD1 gene causes copper toxicosis in Bedlington terriers. Bedlington terriers with this autosomal recessive disorder were shown to have the elevated liver copper levels due to genetic derangement in the biliary copper excretion pathway. DNA samples were extracted from whole blood collected from 257 Bedlington terriers (109 males, 148 females) of pet dog clubs in Korea. A multiplex PCR was carried out to detect of exon 2 deletion of COMMD1 gene. In this study, it was possible to know the existence and prevalence of exon 2 deletion of COMMD1 in Bedlington terriers in Korea. Of the 257 samples, 131 (51%) were wild type homozygous for the normal COMMD1 gene, 108 (42%) were heterozygous, having both normal and mutated copy of the COMMD1 gene. The eighteen (7%) were mutant type homozygous. The results of genetic analysis could help establish proper management strategy and selective breeding program to prevent COMMD1 mutation in Bedlington terriers in Korea.

정주현,최민철 한국임상수의학회 2015 한국임상수의학회지 Vol.32 No.4

A 12-year-old castrated male miniature Schnauzer had anorexia, vomiting, lethargy, and fever for four days. The dog had leukocytosis, thrombocytopenia, hypoglycemia, hypoalbuminemia, hyperbilirubinemia, increased hepatic enzymes on hematologic and biochemical examinations. On abdominal ultrasonographs, there was an enlarged gallbladder with hyperechoic irregular wall thickening. Echocardiography showed vegetative change and regurgitation of aortic and mitral valves. E.coli was identified through ultrasound guided percutaneous cholecystocentesis and bile culture. Bacterial cholecystitis and concurrent endocarditis were diagnosed. The dog was recovered from sepsis with antibacterial and aggressive supportive therapy.

김태환,홍수빈,김민경,신정인,장윤설,이재훈 한국임상수의학회 2015 한국임상수의학회지 Vol.32 No.6

An 11-year-old intact female miniature poodle presented with a four-month history of hemorrhagic effusion. The patient was alert on physical examination, although muffled heart sounds were noted upon auscultation of the right hemithorax. The radiographic finding was pleural effusion. Ultrasonography revealed cystic changes in both ovaries and several nodules in the liver. A refractory opacity in the right lung field, as visualized with computer tomography (CT), was diagnosed as right middle lung lobe torsion with a collapsed bronchus. Five days after diagnosis, a right fifth intercostal thoracotomy was performed to remove the right middle lung lobe; the right middle lung lobe was grossly shrunken as a result of chronic lung lobe torsion. Ovariohysterectomy was also performed. Histopathologic examination revealed papillary adenocarcinoma in both ovaries and suspected metastasized ovarian adenocarcinoma cells in the lung lobe. The patient recovered favorably and had been doing well up to two months post-surgery. However, after four months, the dog presented with respiratory difficulty. The radiographic findings were pleural effusion and collapse of the right cranial and left caudal lung lobes. Malignant cells of epithelial origin were observed in the pleural effusion. The tumor cells were suspected to be metastasized cells from the previously resected lung lobe. Although cancer treatment was recommended, the suggestion was suspended and the dog was discharged from hospital. This was a case of lung lobe torsion that had occurred because of hemorrhagic effusion due to tumor. Although ovariohysterectomy and lobectomy were performed, there was a relapse of hemorrhagic effusion because of metastasized tumor from the previously resected lung lobe.

고규련,홍경화,김재훈 한국임상수의학회 2015 한국임상수의학회지 Vol.32 No.6

A 1-year-old female hedgehog was presented with subcutaneous mass in the right forelimb. Grossly, an elevated subcutaneous mass approximately 4 cm in diameter was located in forelimb. Central dark brown area was surrounded by peripheral milky white zone in the cut surface of mass. Histopathologically, numerous neoplastic cells formed irregular cords or sheets in dermis. Most of neoplastic cells showed palisading features to basement membrane with or without central caseous necrosis. These neoplastic cells showed invasive tendency to adjacent tissues. According to immunohistochemistry, the neoplastic cells demonstrated strong positive signals for pancytokeratin, and negative for vimentin. Based on the gross, histopathology and immunohistochemistry, this mass was diagnosed as basal cell carcinoma in a hedgehog.
