Ununited Anconeal Process (UAP) is defined as a disease of young dogs due to developmental abnormality in which there is a seperation of the anconeal process from the diaphysis of the ulna, leading to a front leg lameness and secondary osteoarthritis. A six -year-old German Shepherd dog was presented because of intermittent right front leg lameness. Diagnosis was made of ununited anconeal process with moderate osteoarthritis by radiographic examination. Surgical removal of ununited anconeal process and curettage of osteoarthritic growth within the elbow joint relieved significant clinical signs despite of size and age of the dog.

As exchanges between countries become more active, new threats such as drugs, illegal imports of food and medicines, and terrorism are present all over the world. From this, increased border security that protects people's safety is becoming a new issue. The activities of special purpose dogs that detect these threats in advance are becoming very important. One of the obstacles in securing superior individuals is musculoskeletal disorders which interfere with the work of special purpose dogs. In order to search for genes associated with these genetic disorders, we conducted genomic analysis using linkage disequilibrium information and investigated genetic characteristics to know heterozygosity and inbreeding status in the population. In this study, two breeds (Malinois, Shepherd) of army dogs and three breeds (Malinois, Shepherd, Retriever) from public databases were used for comparison. The 170K SNP marker panel was used for this study. In the principal component analysis, it was confirmed that clusters were formed for each breed. The number of effective populations differed for each cultivar, but this was due to the difference in numbers of individuals for each breed used for the analysis. The results of heterozygosity decay analysis showed that heterozygous alleles decreased with each generation. In the army dog group, if the population number is maintained properly, the frequency of allele genotype will not decrease significantly.

A strain of Brucella showing the characteristics of Br. suis was isolated from a 55 day-old aborated fetus of a German Shepherd and the cause of the abortion was considered due to brucellosis. A considerable number of dog sera collected at the slaughter house in Taegu city showed antibody titers of 1:80 or more to Br. suis, and serum from the aborted dog 1:320 to Br. suis in titer.

A 5-year-old male German shepherd dog was presented with a 4 day-history of anorexia and depression. Abdominal radiographs showed a large soft tissue mass and loss of serosal detail. Ultrasonographs revealed splenomegaly with the lacy pattern parenchyma, perivenous hyperechoic region at the splenic hilum, and loss of splenic venous flow. Computed tomographic findings included the enlarged non-enhanced spleen except perivenous region at the splenic hilum and a whirled soft tissue mass at the splenic hilum. Exploratory laparotomy confirmed the diagnosis of splenic torsion. Ultrasonographic findings including lacy appearance, hyperechoic perivenous echogenicity and absence of splenic blood flow and CT findings including no or minimal enhancement of the spleen and a whirled appearance of splenic pedicle could be useful for diagnosing isolated splenic torsion in the dog.

Using the CFD method, the pressure drop in 6 cyclone dust collectors of different shape were calculated. And the results were compared with results of the conventional theories. Equations of Shepherd and Lapple (1939, 1940), First (1950), Alexander (1949), Stairmand (1949), Barth (1956) were used in the theoretical calculation. In CFD calculations, we used standard k-epsilon model for analysis of turbulent flow, fluid is $25^{\circ}C$ air, the velocity at inlet is 10 m/s and the temperature is $25^{\circ}C$. In CFD analysis results, the pressure distributions along the flow showed similar patterns in different cyclone shapes. But the pressure drop distributions estimated on the conventional theories had big difference in different cyclone shapes. Only First's theory and CFD analysis showed similar results.

A three-year old intact female German shepherd dog weighing 32kg was presented with the history of regurgitation and vomiting. Physical examination revealed a thin body condition, hoarse voice, hypersalivation, and pelvic limb weakness. In radiograph, meagaesophagus was identified. The neostigmine challenge test was positive. The titer of acetylcholine receptor (AChR) antibody was 1.58 nmol/L (reference range, <0.6nmol). Therefore, the dog was diagnosed to be suffering with chronic generalized form of acquired myasthenia gravis and followed by treatment with pyridostigmine bromide, 1mg/kg, q12 hrs. Treatment improved the pelvic limb weakness, however intermittent regurgitation and vomiting persisted. This resulted in aspiration pneumonia f3r which antibiotics were administered However, the dog was euthanized due to poor management and owner's request.

This study was performed to collect the basic data of DEA 1.1 in four small breed (Maltese, Shih-tzu, Poodle, Yorkshire terrier) and in three large breed (German shepherd, Labrador retriever and Jindo) dogs in the Daejeon area. 105 dogs from 7 breeds (Maltese=20, Shih-tzu=19, Poodle=15, Yorkshire terrier=11, German shepherd=10, Labrador retriever=10, Jindo=20) were selected and tested using the dog blood typing Kit$^{(R)}$ (Korea Animal Blood Bank Inc., South Korea). The prevalence of DEA 1.1 was 83%, that of DEA 1.2 was 17%, and there was no DEA (-) blood type identified in this study. Prevalence according to breeds was Maltese (DEA 1.1, 85%; DEA 1.2, 15%), Shih-tzu (DEA 1.1, 95%; DEA 1.2 5%), Yorkshire terrier (DEA 1.1, 91%; DEA 1.2, 9%), Labrador retriever (DEA 1.1, 90%; DEA 1.2, 10%). One hundred percent of DEA blood type 1.1 was discovered in all of the Poodles and German shepherds, and a higher prevalence of DEA 1.2 was found (DEA 1.1, 40%; DEA 1.2 60%) in Jindo dogs. The prevalence of DEA 1.2 in the Jindo dogs was significantly higher than in other breeds (P<0.01). German shepherds and Labrador retrievers may be more suitable as donor dogs than Jindo dogs in the Daejeon area. Larger scale studies are necessary from more dogs and other areas in South Korea.

Primary renal tumors are uncommon in dogs with prevalence rate of approximately 1%. Renal carcinoma originating from epithelium of proximal convoluted tubules are more likely to be affected to Middle-aged dogs (average age, 8y), males about twice as often as bitches. A 10-year-old, female, German Shepherd dog with history of anorexia, vomitting and hematuria was referred to the Animal Disease Diagnostic Division in Animal and Plant Quarantine Agency. The dog was necropsied and several organs were collected, fixed in 10% phosphate-buffered formalin, embedded in paraffin wax and sectioned for histopathology. Grossly, the kidneys were bilaterally enlarged ($18{\times}12{\times}8cm$; left, $18{\times}10{\times}8cm$; right). The numerous cysts varying sizes from 3 to 6 cm in diameter were protruding from the surface of both kidney. A large nodule ($10{\times}6{\times}6cm$) was discovered between cardiac and diaphragmatic lobe in the right lung. Immunohistochemical examination revealed strong positive reaction to cytokeratin and ki-67 in the nuclei of the epithelial tumor cells. But showed negative reactions to vimentin and CD10. Based on the pathological and immunohistochemical examination, we diagnosed as the bilateral renal cystadenocarcinoma in German shepherd dog.
