Eleven years old cocker spaniel referred to Veterianry Medical Teaching Hospital, Seoul National University was diagnosed as pheochromocytoma. The patient was transferred to the hospital after hit by car and the main clinical signs were tachypnea, tachycardia, edema of hindlimb and lethargy. On ultrasonographic examination, hyperechoic foci was detected and it was invaded into the caudal vena cava. Venography showed the filling defect and local dilation of the caudal vena. The diagnosis of pheochromocytoma is challenging due to the nonspecific clinical signs and severe concurrent disease in dogs. This report describes one dog with invasive pheochromocytoma in which radiography, ultrasonography and venacavography were key diagnositc tools. Ultrasonography was a usuful method for assessment of size, shape and margination of the tumor and invasiveness to the major vessels.

A 12-year-old spayed female Cocker Spaniel was presented with vomiting, diarrhea, depression, and hyporexia of 3-day duration. Microscopic examination of the abdominal fluid from a dog showed basophilic, amorphous to fibrillar materials without bile pigments or crystals. Total bilirubin concentration of the fluid was 19 times higher than the serum bilirubin concentration and exploratory laparotomy revealed a ruptured gallbladder and mucoceles in the abdominal cavity. Rupture of gallbladder mucoceles may cause atypical bile peritonitis in which mucinous material is observed instead of bile pigment.

A 16-year-old, 7.4 kg, castrated male Cocker Spaniel presenting anorexia and weight loss was referred due to a splenic mass, and total splenectomy was performed to resolve clinical signs. Following surgery, the dog developed mild hyperkalemia (6.27 mmol/L) without any clinical symptoms. Further investigations were conducted to determine the cause of hyperkalemia. The serum-plasma potassium difference was measured (1.05 mmol/L), and pseudohyperkalemia was diagnosed. The cause of pseudohyperkalemia was considered as thrombocytosis after splenectomy. The dog did not receive any specific treatment to lower blood potassium. To our knowledge, we report the first case of post-splenectomy pseudohyperkalemia in a dog.

A 10-year-old spayed female Cocker spaniel weighing 6.64 kg was presented with a sign of syncope. Electrocardiographic findings revealed pathologic atrioventricular (AV) block alternating 3rd degree AV block, non-responsive to atropine. Before pacemaker implantation, several anti-hypertensive medications were administered, but there was no improvement. After pacemaker implantation, the heart rate and systemic arterial systolic blood pressure were immediately improved. This is the first report on the resolution of an AV block and malignant systemic hypertension after a pacemaker implant in veterinary medicine.

1년령의 암컷 잉글리쉬 코커스파니엘 견이 3개월 병력의 구토와 구토물의 재섭취, 그리고 체중감소로 내원하였다. 이 환자는 일반혈액 검사, 혈청화학 검사, 방사선 검사, 복수 분석, 담즙산 농도 측정, 탐색적 개복술, 그리고 사후 부검을 통한 간 생검으로 만성 간염 및 간경화증으로 진단되었다. 혈액 검사상 경미한 빈혈, 경미한 간효소치의 상승, CK치의 상승, 저알부민혈증을 동반한 저단백혈증이 관찰되었다. 복수는 분석을 통해서 누출성 복수인 것으로 판명되었다. 담즙산 농도를 측정해 본 결과(fasting; $174.4{\mu}mol/L$ and postprandial; $198.4{\mu}mol/L$)로부터 간기능 부전을 강하게 의심할 수 있었다. 방사선 검사상 복수가 관찰되었고 결국 탐색적 개복술을 실시하여 좌측엽 부위의 간 위축, 장간막 혈관 구조들의 팽창된 소견이 관찰되었다. 간 좌측 후엽모서리 부위에서 봉합법을 통해 생검을 실시하였다. 간 조직의 조직병리학적인 검사 결과 간 세포의 괴사, 동양 혈관의 확장, 동양 혈관 내 호중구의 침착, 그리고 간 세포질의 공포화 등이 관찰되었다. 환축은 저단백 사료 급여 그리고 특수보조제 (ursodeoxycholic acid, prednisolone, vitamine E and interferon)등을 사용하여 관리했다. 구토와 복수는 치료 후 사라졌다. 환축은 정기적으로 혈액 검사, 혈청 화학 검사, 방사선 검사 등을 실시하였다. 이 환축은 내과적인 치료를 받으며 18개월간 생존하였다가 폐사하였다. 사후 부검을 실시했고 조직병리학적인 검사가 시행되었으며 그 결과 간세포에 림프구의 침윤된 진행성의 간경화증으로 판정되었다.

후지마비와 심부통각의 소실을 보이는 5 년령의 수컷 Cocker Spaniel이 내원하였다. 신체검사, 신경검사, 방사선검사와 컴퓨터 단층촬영결과 심부통각의 소실을 동반한 요추 2번과 3번 사이의 디스크 탈출증으로 진단하였다. 편측 추궁 절제술을 시행하여 감압술과 탈출된 디스크 물질을 제거하였으며 $1{\times}10^6$ 개의 동종 지방유래 줄기세포를 $50{\mu}l$ 생리식염수에 희석하여 손상된 척수에 직접 주입하였다. 수술 10주 후, 양쪽 후지 모두에서 심부통각과 운동기능이 완전히 회복되었으며 세포이식과 관련된 부작용은 현재까지 발견되지 않았다. 본 증례를 통해 심각한 정도의 디스크질환을 가진 환축에서 감압술과 병행된 줄기세포의 이식방법은 좀더 나은 예후를 기대하기 위한 치료방법들 중 하나로 고려해볼 수 있을 것으로 생각된다.

We aimed to identify genomic variations as well as the marker genes related with chronic mitral valve disease (CMVD) in Canis lupus familiaris using whole genome resequencing, which provides valuable resources for further study. Two ten-year old female Canis lupus familiaris English cocker spaniels were used for this study, one control and one who had been diagnosed as CMVD. For the whole genome resequencing, muscles from the left ventricular wall were collected from each dog. With the HiSeq DNA Shotgun library and $HiSeq^{TM}$ 2000 platform, whole genome resequencing was performed. From the results, we identified 5 million and 6 million variants in gene expression in the control and CMVD-diagnosed subject, respectively. We then selected the top 1,000 genes from the SNP, INS, and DEL mutation and 675 genes among them were overlapped for every mutation between the control and CMVD-diagnosed patient. Interestingly, in both groups, the intron variant (91.16 and 91.18%) and upstream variant (3.10 and 3.08%) are most highly related. Among the overlapped 675 genes, gene ontology for intracellular signal transduction is highly counted in INS, and DEL, and SNPs (35, 33, 31, respectively). In this study, we found that the COL and CDH gene families could be key molecules in identifying the difference in gene expression between control and CMVD-diagnosed dogs. We believe further studies will prove the importance of variants in key molecule expression and that these data will serve as a valuable foundation stone the study of canine CMVD.

Ninety-nine dogs diagnosed as tracheal collapse were reviewed for 2002-2003 year at Veterinary Medical Teaching Hospital, Seoul National University with clinical records and radiographs. Dogs were ranged in age from 1 to 15 years old (average 8.23 years old) and in weight from 1.2kg to 10.3kg (average 3.3kg). The population included 58 females (6 spayed) and 41 males (8 castrated). It is highly predominant in Yorkshire terrier (64, 64.6%) followed by Pomeranian (10, 10.1 %), Poodle and Chihuahua (8, 8.1%), Maltese (4, 4.0%), mixed breed (3, 3.0%), Cocker Spaniel and Pug (1, 1.0%). The incident rate of female dogs (59%) exhibited relatively higher than that of male dogs (41%). The most prevalent occurrence location was thoracic inlet (60%) of all and carina region (15%), intrathoracic trachea (14%) and cervical trachea (11 %) showed similar rate. Conclusively, tracheal collapse was observed in completely matured or old small breed dogs, largely Yorkshire terrier, on thoracic inlet primarily regardless of gender. These tendencies were apparently similar to previous reports.
