A neutered male, 8-year-old, Pekingese, weighing 4.3 kg with a history of anorexia, sneezing, nasal discharge, and epistaxis for one month was referred. Soft tissue swelling around the nasal bone and small defects of the hard palate with a tiny round dark red mass were found on physical examination. The laboratory tests represented mild leukocytosis. On skull radiographs, soft tissue swelling and osteolytic change of the incisor bone, nasal bone, and maxilla were found. On computed tomography scan images, there was soft tissue attenuating opacity with calcified spots in the bilateral nasal cavities and frontal sinuses. Loss of nasal turbinate pattern and nasal septum was found. And destruction of the insicor bone, nasal bone, maxilla, hard palate, perpendicular palatine bone, and cribriform plate were identified. Nasal malignant melanoma was confirmed by nasal biopsy.

This study was performed to investigate the effects of electrical stimulation on femoral fracture healing in dogs. Eight healthy dogs from 4 to 5 $\beta^3$ were used in this experiment. In the treatment group, anode and cathode were connected to proximal and distal site apart from the fracture line by 2 cm and electrical stimulation was applied to the fracture site for l5minutes by 2 V, 25 Hz and for a month. The control group was connected to electrostimulator as the treatment group, but no electrical stimulation was applied. Various parameters were evaluated including radiograph and serum levels of total-ALP(TALP), bone-ALP(BALP) and osteocalcin. The radiography revealed more rapid callus formation in the treatment group than in the control by about a week. The total-ALP levels of the treatment group were higher than those of the control group from the 2nd to the 24th day(p< 0.05). The bone-ALP levels of the treatment group were significantly higher than those of the control from the 2nd to the 24th day(p< 0.05). The bone-ALP/ total-ALP ratios of the treatment group were higher than those of control throughout this experiment but there were no significance. There were no significance in the osteocalcin levels between two groups. In conclusion, the electrical stimulation on femoral fracture site was effective for bone healing in dogs.

A 12-year-old male poodle weighing 2.0 kg presented for evaluation of right thoracic limb lameness. The owner reported that the dog showed recurrent bilateral shoulder joint luxation after a car accident for a year. Recently, the left shoulder joint appeared well maintained, but right shoulder joint luxation was exacerbated. On physical examination, the dog showed non-weight bearing lameness on the right thoracic limb. Craniocaudal radiographic views revealed medial displacement of the right humerus. Mediolateral radiographic views revealed overlap of the glenoid cavity and humeral head. Muscle atrophy of the right thoracic limb, reduced biceps brachii muscle tendon tone, a tear of the medial glenohumeral ligament, and a rupture of the subscapularis tendon were identified intraoperatively. Transposition of the biceps muscle tendon was performed. However, at 7 days, there was evidence of right shoulder reluxation on radiographs. The second surgery was performed with two $2mm{\times}6mm$ cortical bone anchors and a $4mm{\times}6mm$ cancellous bone anchor placed in the cortical bone of the distal scapula and the cancellous bone of the proximal humerus respectively. Two scapular bone anchors were then connected with a humeral bone anchor using heavy nylon suture to minimize shoulder abduction range of motion. On radiographs right after surgery and 6 weeks after surgery, the affected limb revealed no evidence of medial shoulder luxation. At 6 months, no evidence of lameness was noted on the right thoracic limb.

Freeze-dried cortical bones of the goat were transplanted to the experimental fibular defect of 10 dogs for valuating the possibility of xenogeneic bone implantation and the specificity of BM(Bone Morphogenetic Protein). The . freeze-dried cortical bone eliminated antigens and defatted with chloroform and methanol were freeze-dried at $-80{\circ}C$ for preservation of BMP and then sterilized with 50 gas and storaged in room temperature. Ten freeze-dried cortical implants of the goat were transplanted in experimentally defected regions of bilateral fibula of 5 dogs in clinically normal. The transplanted region had been radiographed for observing state of bone union and BALPOone Alkaline Phosphatase) in the serum of the host was measured for valuating activity of oteoblast per 2 week-interval after transplant procedures. New bone formation had been observed early in one of ten regions around implants about the same time as autoimplant regions. It was incorporated with its host bone during 4-12 weeks after transplantation. In another 2 cases of 2 dogs, new bone formation and absorption of implant had been observed from 4 weeks but they were not incorporated completely until 20 weeks. The rest of the freeze-dried bone implants, 7 cases of 4 dogs had not been observed new bone formation nor absorption of implants. The freeze-drying method for implants means to not influence bone incorporation. Although less of union percentages the union form of this experiment were similar to alloimplantation and it may mean to block immunity reaction that disturbs the bone induction by BMP. It demonsknted that the possibility of the xenogenous bone implantation is recognized by reason of the low specificity of BMP between goat and dog.

Detection of wooden foreign body represents a clinical challenge. Wood is typically radiolucent, so wooden foreign bodies are generally cannot be seen on survey radiography. Failure to locate and remove foreign bodies can lead the patient to the long-term secondary inflammatory reactions or infections. The dog described in the present report ingested a wooden foreign body(cotton swab stick) a year ago. The foreign body remained in the intestinal tracts which were attached to each other due to the prior abdominal operation. The wooden piece in the intestine functioned as a nidus and inorganic matters were gathered forming calculus on the outer layer of foreign body. In the radiograph, the foreign body appeared to be a chicken bone which of it's inner area was more radiolucent than the outer layer. Because the wooden foreign bodies that have remained for long time in the intestinal tract can be seen like a bone by mineralization, the diagnosis of the wooden foreign bodies should be done prudently.

Generally, a vertical rolling process is used to achieve extensive width reduction in hot strip mill. However, it is impossible to avoid the defects such as dog-bone and edge-seam defect. The sizing press process has been developed in response to the defects mentioned above. Especially, this study is carried out to investigate the deformation of slab by two-step sizing press. The deformation behavior of slab in the sizing press process is more favorable than that in conventional vertical rolling edger. The FE-simulation is applied to predict the deformation behavior of the slab. In this paper, the several causes of the asymmetrical deformation are mentioned for the purpose of understanding of the anvil shape. Load, dog-bone and edge-seam defect are discussed in width sizing process considering the anvil shape. And to reduce the problems generated at rougher mill just after sizing press, these are studied in this paper. The deformation behavior of slabs and optimum anvil shape are obtained by rigid-plastic finite element analyses and neural network.

A 22-month-old female mongrel dog weighing 4.8 kg was referred with chief complaint of bite wounds and lameness. The patient showed non-weight bearing lameness on left hindlimb and lateral instability of intertarsal joint. On radiograph, proximal intertarsal luxation between calcaneus and fourth tarsal bone was diagnosed. To imitate the long collateral and calcaneoquartal ligament, bone tunnels were drilled in the distal calcaneus and proximal fifth metatarsal bone. The figure-eight suture was placed with 0.5 mm cerclage wire through the predrilled holes. At 2 weeks after surgery, the lameness of hindlimb was still present. However, the patient had weight bearing lameness for 4 weeks after operation and was able to walk and run without lameness at 5 weeks after surgery. This case report explains the successful correction of intertarsal luxation with a single figure of eight wire suture in case of luxation to the intertarsal joint.

The purpose of this study was to compare the bone formation, maturation around HA-and titaniumcoated dental implants in dog. 5 hydroxyapatite coated IMZ implants and 5 titanium coated IMZ implants were placed into the previously extracted site in the mandible of 5 adults dogs. All dogs were injected intravenously Tetracycline, Alizalin red S, and Calcein for bone fluorescent labelling, After the experimental period of 16weeks, the dogs were sacrificed and tissue samples around the implants were obtained. Microscopic observations(ligth, polariged and fluorescence microscope), morphometric analysis, line profile with EPMA, and quantitative analysis for Ca,P, and Ti were performed. The results were as follows ; 1. Bone maturations around the implants were relatively lower than those of natural teeth. No significant differences in bone maturation and remodeling patterns were observed between the two implants groups. 2. Calcification of bone surrounding the implants was initiated in 8-11 weeks for HA-coated implants, while it took 11 weeks or more for Ti-coated implants. 3. Bone-to-implants contact ratio of 82.63% was recorded for HA-coated group and 72.25% for titanium coated group, with no significant difference between the two groups. 4. Bone around the implants exhibited reduced quantity of Ca and P in the $100{\mu}m$ region relative to natural teeth, while the rest of the regions showed no statistical differences. No significant differences were found between the two implant groups. 5. There was a separation of HA layer from the implant core and subsequent infiltration of inflammatory cells into the resulting space in the HA-coated implants, and evidences of phagocytosis of HA particles by macrophages. Bone calcification was more rapid around HA-coated implants compared to titanium-coated implants, but HA coated implants did not show any significant differences either in the degree of calcification or the bone-to-implant contact ratio over Ti coated implants. HA coated implants may have complications associated with HA absorption and separation of HA layer from the implant core.

A five-month old female dog was presented to Teaching Anilmal Hospital, Gyeongasng National University for femur fracture. Previously the dog had been presented to a local hospital. Orthopedic and blood examinations were conducted. There was absent response of conscious propri- oception. The dog stood knuckled onto the digits and had hock dropped, but showed no117a1 values in WBC.RBC, Hb, PCV, BUN, Creatine, Glucose, Cholesterol, AST and ALT. Plain radioaraphs were taken and there were abundant periosteal reaction and malalignment of fragments. The dog was anesthetized and prepared for aseptic surgery. Joshi external fixator and half pins were applied(uni lateral). AT 8 weeks after surgery, the pins were removed from the bone. The fracture was well healed wish no evidence of original fracture line. but mild muscle atropy and shortening of femur were found.

A male German Shepherd dog, $2{\frac{1}{2}}$years of age, was admitted with sudden anemia, weakness, hyperpyrexia, anorexia and lethargy. The patient showed hypoplastic anemia, thrombocytopenia, absolute and relative lymphocytosis, absolute and relative granulocytopenia, hypoalbuminemia, slight hepatic disorder, slight azotemia, hematuria and proteinuria by the screening examination. The bone marrow aspiration smear showed high cellularity, severs infiltration of lymphoblasts and prolymphocytes, and mitotic figures of lymphoid cells. The liver aspiration smear demonstrated infiltration of lymphoblasts. Acute lymphoblastic leukemia was diagnosed as none of the superficial lymph nodes showed enlargement and marked functional disorder of important organs other than the liver was not found. The patient was treated with vincristine, cyclophophamide, predniosolone for chemotherapy and blood transfusion and either ampicillin or cefoperazone for supportive treatment. But the patient did not show marked remission and died 9 days after the start of the chemptherapy. The necropsy was not permitted.
