In a kenel of 62 dogs, 33 were diagnosed as infected dogs Brucella canis by serological test and blood cultures in a large kennel in Chonnam area. Twenty eight of 33 dogs were treated with combined antibiotics therapy consisting of tetracycline and dihydrostregtomycin. After the first treatment, all dogs became abacteremic and serologic titers declined. Abortion due to B canis infection could be prevented by antibiotic therapy during pregnancy. However, sequential antibiotics therapy for 4 weeks did not eradicate B canis from affected bitch. According to results of serological and blood culture tests, effect of antibiotics treatment respectively revealed that 17 of the originally infected dogs were cure with second therapy schedule at 2 months and 27 of that with 6 months after second therapy.

This study was investigated of the bone healing capacity by autologous fibrin glue in experimental bone defect dogs. The autologous fibrin glue manufactured just before the experiment was mixed with the concentrated fibrinogen from whole blood of the experimental dog and bovine thrombin. The experimental group was constituted with seven dogs. The experimental osteotomy was performed 5 mm length in bilateral region of proximal diaphyseal fibulae. The defected regions of experimental group were filled with the autologous fibrin glue by duploject. The experimental regions had been radiographed biweekly for 16 weeks to observe new bone formation and union. Bone alkaline phophatase (BALP) in all groups was evaluated biweekly till the end of the experiment to determine osteoblast activities. New bone formation had been observed in five regions of three dogs at four weeks after the experimental treatment and in two regions of one dog at ten weeks. The other seven regions of the experimental group and control group were not observed new bone formation until the end of the experiment. BALP value in four dogs observed new bone formation was increased to 97.10 IU/L (453.96%) at two weeks after the experimental treatment. The results of this experiment were suggested that the autologous fibrin glue was moderately effective in new bone formation in dogs.

This study examined the therapeutic effects of aromatherapy for the treatment of otitis externa in dogs. Eleven dogs with otitis externa were examined. The control group (5 dogs) was treated with susceptible antibiotics, and the experimental group (6 dogs) was treated with aroma-oil applied topically to the ear canal. The aroma-oil contained 10 ml sweet almond oil, 0.3 ml bergamot oil, 0.2 ml lavender oil, 0.1 ml tea tree oil and 0.1 ml roman chamomile oil. The blended aroma-oil (0.1 ml) was applied to the ear canal twice daily for 2 weeks. The authors examined the changes in the clinical signs, bacterial count in discharges, total WBC count and neutrophil/lymphocyte ratios in the two groups. The bacterial cell counts in the experimental group were significantly lower at one (p < 0.01) and two weeks (p < 0.05) after treatment than the control group. These results suggest that aromatherapy is an effective and practical treatment for otitis externa in dogs.

This study was purposed to make the referenced range of stomach antral contraction strain in 50 dogs using 2-dimensional speckle tracking. In addition, the strain results were compared among body condition scores to reveal the correlations of obesity among the subjects of the study. Finally, the medetomidine group that was comprised of 10 dogs was compared with the normal group to identify the medetomidine pharmacologic effect in the stomach antral contraction. Clinically healthy 50 dogs were recruited for the study. In an ultrasonographic examination, the stomach antrum region was scanned, and at least one cycle of antral contraction was recorded. The peak strain of antral contraction in healthy dogs was 58.2 ± 20.47% (mean ± SD). The obesity group showed a high strain result and there were significant correlations between the body condition score (BCS) 2, BCS 3 groups and BCS 8 group. The medetomidine group revealed a low strain result and was significantly correlated with normal group. Two-dimensional speckle tracking was useful to the evaluation of stomach motility disorders.

Seven cases of canine babesiasis were observed by clinically, hematologically and immunologically in the Kyungbook and Pusan area from May 1961 to October 1963. And a survey was conducted on the rising pups for their babesia, infection in the broken out districts of the disease. The results obtained were as follows: 1. Severe cases of canine babesiasis due to the same agent have been encountered in various breed, of dogs in widely separated location in the Kyungpook and Pusan area. 2. The principal symptoms oserved in infected dogs were severe anemia, weakness, inappetence, moderate fever or subnormal body temperature, increased respiration and pulse, palpitation, icterus, hemogrobinuria and redish yellow defecation. 3. Of hematological findings, decrease in erythrocytes count, hemoglobin content was evident and severe anemic changes occured which were associated with macrocytic anisocytosis. The differential leucocytes counts showed a tendency to increased monocytes and decreased monocytes and decreased basophil. 4. The principal anatomic chabges observed in two cases of infected dogs were severe anemic and icteric changes, markedly enlarged spleen, and enlarged liver with distended gall bladder. 5. Haemaphysalis bispinosa was suspected as being the principal vector of the infection. 6. It was suspected that chronic canine babesiasis would prevailed widely in Kyungpook and Pusan area, and that dogs are raised in such infected environment usually suffer only from the mild, chronic form, which may be practically symptomless, while imported dogs usually suffer from the acute form of the disease.

This study was conducted to survey pathogens of canine coronavirus (CCV), canine distemper virus (CDV), canine influenza virus (CIV), canine parvovirus (CPV), severe fever with thrombocytopenia syndrome virus (SFTSV), Dirofilaria (D.) immitis, Giardia and antibodies against Anaplasma (A.) phagocytophilum, Borrelia (B.) burgdorferi, Brucella (B.) canis and Ehrlichia (E.) canis among stray dogs in Gyeonggi province. We collected 271 feces, 291 bloods, 311 nasal and ocular swab samples from 311 of dogs in the Gyeonggi province assistance dogs sharing center from January to December, 2019. Among canine infectious disease pathogens, Giardia was highly detected in 46/271 (17.0%) samples. Subsequently, CCV 10.3% (28/271), D. immitis 8.2% (24/291), CPV 4.1% (11/271), CDV 1.0% (3/311), A. phagocytophilum (antibody) 0.3% (1/291), E. canis (antibody) 0.3% (1/291) were detected. Based on the results, this study is expected to provide a useful reference for disease control and management of stray dogs.

Canine mammary gland tumors are the most common neoplasms in intact female dogs. Approximately half of all mammary tumors are malignant, and there is a risk of metastasis, which is associated with a poor prognosis. This study was to evaluate the prognostic factors of canine mammary gland tumors and the risk factors associated with the development of malignant tumors. From 2014 to 2020, 60 dogs with mammary gland tumors that underwent surgical treatment were evaluated in this retrospective study. Tumor size, TNM stage, and histopathological results were prognostic factors for 2-year survival after surgery. Every 10 mm increase in tumor size, increased the risk of death within 2 years after surgery 1.213 times. Dogs with TNM stage IV or V had 8.667 fold risk of death within 2 years after surgery. The 2-year survival rate for dogs with benign tumors was 90.2% and for malignant tumors was 67.3%. Tumor size is the most important prognostic factor for canine mammary gland tumors. As tumor size increased by 10 mm, the risk for development of malignant tumors increased by 1.487 times. Tumors larger than 30 mm are highly likely to be malignant, and metastatic evaluation and wide resection should be considered.

SDK (skin decontamination kit) is new skin decontaminant which is developed by ADD (Agency for defence development). In this study, four-week toxicity of SDK was investigated using beagle dogs and Sprague-Dawley rats. The beagle dogs and Sprague-Dawley rats were dressed topically seven days per week for 28 days, with dosage of 0, 0.25, 0.8 and 1 g/kg/day. respectively. Animals treated with SDK did not cause any death and show any clinical signs. They did not show any significant changes of body weight, feed uptake and water consumption. They were not significantly different from the control group in urinalysis, ocular examination and histopathological examination. In hematological and serum biochemical assay, there were no-dose-defendent changes. Therefore, SDK was not indicated to have any toxic effect in the beagle dogs and Sprague-Dawley rats when it was dressed topically below the dosage 1 g/kg/day for four weeks.

This study was performed to determine the effects of anastomosis on the internal diameter and wall thickness of jugular vein. Tro shepherd dogs were used for this experiment. In dog 1, xylazine(2 mg/kg) and ketamine(5.5 mg/kg) were injected intramuscularly for induction followed by enflurane(3%) anesthesia. In dog 2, acepromazine(0.03 mg/kg) and ketamine(5 mg/kg) were injected intravenously for induction followed by enflurane(3%) anesthesia. The dogs were heparinized(1 mg/kg) for the prevention of thrombosis. After jugular vein was exposed by incision of left cervical area, two Johns Hopkins bulldog clamps were clamped. Jugular vein was cut between two clamps, and it was reanastomosed using 5-0 silk. Ultrasonography was done along the jugular vein on both sides of each dogs 21 days after anastomosis surgery. The internal diameter and circumference of the vein in the anastomosis area were markedly reduced with thickening of the vein wall, but no thrombi were observed.
