A 18-month-old, 35.3 kg, intact male Cerman shepherd dog with a history of non-weight bearing lameness in the right hindlimb was referred to Veterinary Teaching Hospital, College of Veterinary Medicine, Kyungpook National University. On physical examination, pain response was elicited. Laboratory abnormalities were not present. Radiographic examination revealed areas of increased opacity in the medullary cavity and accentuation of trabecular patterns of the affected bone. This dog was treated with analgesics and lameness was resolved without pain.

A case of ovarian teratoma is reported in a 11-year-old female Korean Jindo dog. Grossly, the left ovary was markedly enlarged ($5{\times}4{\times}4 cm in size$) and contained several cystic spaces filled with hairs and yellowish, fragile deratinous material on cross section. Histological observation of the hair and keratin containing cystic structures lined by stratified squamous epithelium, mature adipose tissue, and bone and cartilage is compatible with a diagnosis of ovarian teratoma, pyometra was also present in this dog. This is believed to be the first report on canine ovarian teratoma in Korea.

This study aimed to determine of osseointegration following dental implantation in the dog mandible using bone scintigraphy. Five mongrel dogs, weighing approximately 8.5 kg and averaging 1.8 years of age, without active periodontal disease were used. During the entire study period, all dogs were fed a soft commercial diet and water ad libitum to minimize functional loading of the implant. Titanium alloy implant systems 10 mm in length and 4 mm in diameter were chosen for insertion. Twelve weeks prior to implantation, the second and third left mandibular premolars in each dog were extracted for the dental implant insertion. Before the dental implantation procedures and 0, 4, 8, and 12 weeks after the insertions, clinical observation, radiography and bone scintigraphy were conducted. The scintigraphy was obtained using a large field of view gamma camera equipped with a paralled-hole, low-energy collimator about 3 hours after intravenous injection of Tc-99m-MDP (8 mCi/dog) to the dogs. There were not inflammation sign after insertion of dental implants on the mandible in dogs. Implants were slightly movable at the first and fourth weeks, and there was no mobility after 8 weeks. Twelve weeks after dental implantation, the bone uptake scintigraphy of peri-implant bone was similar to that of normal alveolar bone, indicating that peri-implant bone was completely regenerated by new bone. In conclusion, we recommend stable implant fixation with alveolar bone for the accurate and safe repair of teeth loot due to decacy, trauma or peridontal disease. Titanium alloy implants were optimal due to their biocompatibility.

Elbow hygroma and hypertrophic osteodystrophy were diagnosed in Doberman referred to Veterinary Teaching Hosptial of Chungbuk national University. Physical examination, plain radiography, and bone scan were performed in the patient. The radiography revealed soft tissue swelling on the caudal region of the elbow and irregular radiolucent zone involving the metaphysis subjacent and parallel to the distal radial and ulnar physes. The bone scan of the forelimbs revealed increased uptake in region where the soft, fluid-filled mass on the elbow was present. But the radiolucent areas (the distal radial and ulnar physes) were seen normal bone uptake. Therefore, hypertrophic osteodystrophy ruled out the diagnosis. $^{99m}Tc-MDP$ scan is suitable to routine clinical use for soft tissue inflammation and bone lesions detection.

Installation periods of implants in Mx. and Mn., is related to pattern of bone formation. The purpose of this study was to observe histologic response in osseointegration at root formed implant-tissue interface at Mx. and Mn., the other is comparison of osseointegration level between Mx. and Mn. at 8 weeks. In this study, unilateral upper & lower molars were extracted in dog. After allowing to heal for 4 months, two kinds of osseointegrated implants Swedevents, Corevents-were inserted in dog. The specimens were treated by conventional method. The interface zones between bone and implant were investiigated using X-rays, light microscope. The following results were obtained from this study. 1. Around titanium implants that were installed in Ma and Mn., Radio lucencies don't exist 2. There are not inflammation and mobility of titanium implants that were installed in Mx. and Mn. Most of implant surface are covered by bony tissued partly by bone-marrow tissues. 3. Titanium implants installed in Mx, in contrast to same implants in Mn., shows more coverage by bone marrow tissue and lack of apposition lamellar bone, which lead to the assumption that bone formation in Mn. is faster than in Mx.

A 6year-old intact male hound cross dog, weighing 23 kg, was presented to the Teaching Animal Hospital, Chonbuk National University with the history of gunshot wound at the left elbow joint. Survey radiographs of the affected elbow revealed the presence of a metallic bullet caudal to the olecranon processes and comminuted fracture of the proximal radius and ulna. The first treatment strategy included removal of the bullet and fixation of the radius and ulna using separate bone plates, bone screw, K-wire and surgical wire, was failed. The second treatment strategy included olecranon osteotomy and rigid immobilization of the elbow joint with a bone plate applied to the caudal aspect of the humerus and ulna along with autogenous bone grafts collected from the 13th rib. The optimal angle of the joint following arthrodesis of this case appeared to be 130°. This resulted in improving the case but after 60 weeks the plate was bent and there was exudation from the wound. The third treatment strategy was the same with the second except for that the bone autografts were collected from the proximal metaphyses of the ipsilateral humerus. This resulted in a successful arthrodesis 6 weeks after the surgery. Elbow arthrodesis with bone autograft resulted in acceptable function, but abnormal gait remained in the dog due to mechanical interference with the movement of the joint.

This paper presents a comparative evaluation of five different types of steel fibers used as reinforcing material in concrete beams. Two types of plain and RC beams were prepared to compare the relative flexural behavior. The fibers used were dog bone (paddled), both ends hooked. コ-type straight. crimped and wavy type with aspect ratio of 43 to 75. Fiber volume fraction of 1 to 2% were used while shear span to depth ratio (aid) and steel ratio p were fixed. Fiber reinforcement effect index Ef and effective toughness index Te were adopted to evaluate fiber reinforcing effects. The effect of fiber reinforcement on flexural strength is higher in plain beams than in RC beams. Hooked and dog bone type fibers were found to be more effective than the other type ones in enhancing the flexural strength and post-peak energy absorption capacity of concrete beams.

A white-yellowish 5-7 cm sized solid mass was observed in the mammary gland of a 7 years old poodle bitch. Mass was well-defined and metastasis was not observed. In microscopic findings, mass contained hyperplasia of glandular epithelial cells, proliferation of mucin-secreting myoepithelial cells and their stroma and formation of cartilage and bone. Bone marrow with fat and hematopoietic cells was observed. Based on the microscopic findings, the mass was diagnosed as benign mixed tumor of the mammary gland in dog.

A five-year-old spayed female Labrador retriever presented with right forelimb lameness one day earlier. Radiographs and computed tomography of the right shoulder joint revealed conspicuous enthesophytes, bone cyst, and bone fragment at the intertubercular groove. Magnetic resonance imaging showed a loss of continuity of the biceps tendon and inhomogeneous hyperintense signal of the surrounding soft tissue and moderate synovial fluid on T2- and proton density-weighted images with contrast enhancement on the postcontrast T1-weighted images. The dog was diagnosed with tenosynovitis and biceps tendon rupture with osteoarthritis based on a comprehensive evaluation of the computed tomography and magnetic resonance imaging features.

A 13-year-old neutered male Maltese dog presented to our hospital with lethargy and anorexia. Laboratory abnormalities included severe non-regenerative anemia (hematocrit, 12.9%; reticulocyte count 12.8 K/µL). The cytology of bone marrow revealed erythroid hypercellularity with mild myelofibrosis. Therefore, late-stage precursor-targeted immune-mediated anemia (PIMA) was diagnosed. Multimodal treatment including 2 immunosuppressant drugs (prednisolone and mycophenolate mofetil), antithrombic drug (clopidogrel), and blood transfusion was performed. The dog showed complete remission from PIMA, and the total duration of follow-up was 622 days. This is the first case report of canine PIMA managed successfully with prednisolone and mycophenolate mofetil in Korea.
