A 10-year-old mixed male dog, weighed 4.2kg, was referred to an animal hospital in Pusan. Clinical signs were generalized alopecia, cough, cardiac murmur, dehydration, and right side cryptorchidism. Testis was surgically removed, fixed in formalin and submitted to Diagnostic Laboratory, Chonbuk National University. Grossly, right testis was enlarged. A bulging tumor mass of right testis was homogeneous and grayish white in cut surface, but left testis was normal. Microscopically, no border lines of tubules were formed and the cells grew diffusely, forming sheets with scant supporting stroma. Tumor cells were fairly uniform in size and round or polyhedral, and had discrete cellular lines. The nuclei were large and of variable size, and ovoid, round, vesicular but the cell cytoplasm was scanty. Mitotic figures were common. And giant cells and vacuolated histiocytes were scattered, which is called starry sky appearance. This is the case of seminoma with diffuse type in a mixed dog.

한재철 ( Jae Cheol Han ),한규삼 ( Kyu Sam Han ),이성희 ( Sung Hee Rhee ),마쓰다기꾸 ( Kiku Matuda ),임병무 ( Byung Moo Rim ),임채웅 ( Chae Woong Lim ) 한국가축위생학회 2001 韓國家畜衛生學會誌 Vol.24 No.1
Hepatic coccidiosis was occurred in a rabbit farm in Chonbuk province. Clinically, rabbits showed anorexia, diarrhea, dehydration, and depression, subsequently died 3-5 days after onset of clinical signs. Grossly, multifocal white spots or lines on the liver surface were observed. Histopathologic lesions included hyperplasia of bile duct epithelium with infiltration of inflammatory cells such as plasma cells and granulocytes, which represents chronic pericholangitis. Different developmental stages of Eimeria stiedae were observed inside the epithelium of biliary system. This is the case of hepatic coccidiosis in rabbits.

급식패턴에 따른 성장기 개의 신체지수(BCS)에 대한 조사 및 고찰
조성진,마쓰다 기꾸,이성호,박영석,김병수 충남대학교 형질전환복제돼지연구센터 2007 논문집 Vol. No.10
Feeding Puppy at the first 6 months is substantially important and give effects on general health status during whole life of the animal. Concerning to feeding method, any one of free choice feeding, time limiting feeding, amount limiting feeding is usually selected by owners. We surveyed recent 3 years' 1251 veterinary medical records in a local private veterinary hospital and selected all cases (661) that visited the hospital from 0 to 6 months of age. The followings were investigated: sex, breed, present feeding style, whether Body Condition Score (BCS) was low or not, whether client education on feeding style was done or not. The results showed: (1) small breeds that occupying 66.3% were most often fed time-and-amount limited, and (2) the restricted feeding was significantly related to low BCS. Owner pre-education about feeding should be encouraged especially on small breeds.

골절단을 이용한 급속 치아이동 후 치수 및 치주조직 변화
강경화,김은철,이선경,임채웅,마쓰다 기꾸,태기출,김상철 대한치과교정학회 2004 대한치과교정학회지 Vol.34 No.2
본 연구는 골절단을 이용한 치아-치조골 분절의 급속 치아이동 후 치수, 치주인대 및 치조골의 변화를 유성견에서 평가하고자 하였다. 하악 제4소구치의 근심, 원심, 치근단 부위에서 피질골을 절단하여 치아-골 분절을 형성하고 하악 제3소구치를 발거하면서 협측, 설측 부위의 피질골을 삭제하였다. 1주 휴지기 부여에 따라 휴지기군과 비휴지기군으로 나누어 치아의존형 견인장치로 6일 동안 견인하고 강화기를 거친 후 0주, 1주, 2주, 4주, 6주, 8주에 희생시켜 치수, 치주인대 및 치조골의 조직 변화를 임상적, 방사선적, 조직학적 및 면역화학적으로 평가하여 다음과 같은 결과를 얻었다. 1. 치아이동 양과 강화기 동안의 조직 치유 양상에서 휴지기 유무에 따른 차이는 없었다. 2. 견인측에서 골형성은 강화기 8주까지 계속되었는데 강화기 1-2주에 가장 활발하였으며 6-8주간의 변화는 적었다. 3. 비휴지기군의 강화기 1주에서 치조골 흡수 및 파골세포 출현, 염증세포 침윤이 가장 많았으며, 특징적으로 파상아세포가 압박측의 치주인대와 치수 내에 나타났다. 4. TGF-β는 치조골의 골기질 및 골모세포, 파골세포, 치수 내 파상아세포에서 강양성 발현을 보인 반면 치수, 백악모세포, 무세포성 백악질에서 경미한 양성 발현을 나타내는 부위 특이성이 있었다. 5. TGF-β는 견인측 치주인대의 치조골에 인접한 혈관 및 치주인대세포, 골모세포에서 강화기 초기 1-2주에 주로 발현되었으며 6주 이후에는 발현이 크게 감소하였다. The movement of tooth-bone segments by osteotomy can simultaneously shift tooth and surrounding alveolar bone in a relatively short period. The purpose of this study was to evaluate the tissue changes in pulp, periodontal ligament, and alveolar bone in rapid tooth bone movement with osteotomy. The mandibular 3rd premolar of a dog was extracted and cortical bones of the buccal and lingual area were eliminated, and then cortical bones around the mesial and distal area of root, and below the root apex of the mandibular 4th premolar were osteotomized. After a one week latency period, a tooth-borne distraction device was activated for 6 days. And pulp, periodontal ligament and alveolar bone were evaluated clinically, radiologically, histologically and immunohistochemically at 0, 1, 2, 4, 6, 8 weeks of the consolidation period and conclusions were reached as follows. 1. Latency period didn't affect total amount of tooth movement and healing process of tissue during consolidation period. 2. Bone formation continued through 8 weeks of consolidation in distracted side, with a high peak at 1-2 weeks, and the lowest at 6-8 weeks of consolidation. 3. At 1 week of consolidation, alveolar bone resorption, osteoclast appearance and inflammatory cell infiltration were the most active, and dentinoclasts characteristically appeared on the pulp and pressure side of the periodontal ligament. 4. The expression of TGF-β was area-specific, as it was strong-positive at bone matrix, osteoblast, osteoclast of alveolar bone, and dentinoclast inside pulp, but weak in pulp, cementoblast and acellular cementum. 5. The expression of TGF-β was generally observed at the initial 1-2 weeks of consolidation at vessels, periodontal ligament cells, and osteoblast near alveolar bone on the distraction side of the periodontal ligament, and was significantly decreased after 6 weeks of consolidation.
