The prevalence of canine heartworm(Dirofilaria immitis) infection in 150 mixed-breed dogs(male : 54, female : 96) from February to December 1997 was investigated by using antigen test kit(ICT $GOLD^{TM}$ HW, Synbiotics, USA) based on immunochromatographic assay in Inchon city. Also, gross and histopathological findings of an antigen positive dog were carried out. The results were summarized as follows ; 1. Four dogs were positive from 150 tested dogs(2.7%). They were all more than 2 years old and infection rates in male and outdoor dogs was higher than those in female and indoor, respectively. Species of infected dogs were Pug(2) , German Sheperd(1) and Great-dane (1). 2. Regional infection rates were closely related with housing system in the city. 3. Pathological findings of antigen-positive dog was excessive enlargement, congestion and hemorrhage of lung and D immitis in heart and histologically hemosiderin, hypertrophy of pulmonary alveoli wall and irregular hypertrophy of pulmonary artery inner wall. Microfilaria was observed in pulmonary artery and arteriole, ventricle and splenic artery.

Observations were made on the infection rate of common internal parasites in dogs in Kwangju area from January to March, 1982. Dog's stools were collected from veterinary hospitals, houses, intensive dog-rearing places and sidewalks. On the basis of egg counting, the following results were obtained; 1. Of 464 fecal samples, 73.5% were appeared as positive. 2. Dogs from veterinary hospitals and intensive dog-rearing places have higher infection rates than others. 3. Of the parasites detected, Toxocara canis was the most commonly encountered (23.7%). 4. Ascarids, flukes and coccidia were more prevalent in pups than in mature dogs, whereas bookworms were detected less often in young dogs than in older ones. 5. There were significant (p<0.01) differences among age categories for all parasites except tapeworms.

This study examined the efficacy of apitoxin for the treatment of otitis externa in dogs. Ten dogs with otitis externa were allocated randomly to two groups. The control group was treated with the susceptible antibiotics and the experimental group was injected with apitoxin into the tragus subcutaneously. There were no significant differences in the clinical scores, blood WBC counts and neutrophil/lymphocyte ratios between the control and experimental groups. By 2 weeks, the bacterial cell counts were significantly lower in the experimental group than the control (p < 0.05). No adverse reactions were observed in any of the dogs during the study. This suggests that a topical injection of apitoxin is an effective treatment for otitis externa in dogs.

Clinical outcomes of dogs treated for end-stage otitis extema with total ear canal ablation (TECA) combining lateral bullar osteotomy (LBO) at Veterinary medical teaching hospital of Seoul National University from 2001 to 2003 were evaluated. In 14 dogs, 23 ears, the operation was successful in alleviating all clinical signs of otitis externa and media. The main complication after TECA combining LBO were facial nerve paralysis and the others were recurrent infection and the formation of fistula and cyst. Two cases were tumors. One was ceruminous gland adenoma and the other was squamous cell carcinoma. The operation successfully resolved the original problems in 100% (23 of 23) of the surgically treated ears of these dogs.

This survey was performed to investigate the seroprevalence of antibodies to Brucella canis in dogs from public animal shelters and breeding kennels in Incheon. A total of 402 dogs selected randomly were tested serologically by using immunochromatographic antibody test kit. None of 289 dogs in public animal shelters were sero-positive and 10 (8.9%) of 113 dogs in breeding kennels were sero-positive. 5 (4.4%) strains of Brucella canis were isolated from 10 sero-positive dogs' blood. Antimicrobial susceptibility test was carried out by Disk diffusion method. They were susceptible to tetracyclines, quinolones, aminoglycosides and combination amoxicillin with clavulanic acid.

This study was conducted to determine the serum cardiac troponin I (cTnI) concentrations in clinically normal (uninfected) Korean Jindo dogs and those infected with Dirofilaria (D.) immitis. Forty Korean Jindo dogs (22 females, 18 males) were obtained from two kennels in the Boryeong area of Chungnam Province and the Daejeon area, Korea. Significantly higher cTnI concentrations were observed in D. immitis-infected dogs than clinically normal dogs. cTnI testing in addition to thoracic radiography, echocardiography, and electrocardiography shows promise as an additional method for diagnosis of heartworm infection.

This study was performed to evaluate the effects of ocular bacteria and tear lactoferrin on the Tear Staining Syndrome(TSS) in poodle dogs. Staphylococcus, Klebsiella, Micrococcus and Pseudomonas were the most Prevalent microorganisms isolated in normal eyes of poodle dogs, whereas the predominant isolates in the poodle dogs with TSS were Micrococcus, Staptococcus and Staphylococcus. There were no significant differences between the normal and tear-stained poodle dogs in the quantity of tear lactoferrin. In vitro hair staining experiment, bacteria isolated from the eyes with TSS and lactoferrin didn't stain hair. The results have shown that either ocular bacteria or tear lactoferrins were not related to the TSS.

In 2001, eight small-sized dogs and three medium-sized dogs with or without clinical signs such as vomiting, dyspnea and enlargement of superficial lymph nodes were diagnosed as lymphoma by radiography, ultrasonography and cytology. Among them, six were female mainly over 7 years old and others were male around 4 years old. There were six cases of multicentric form lymphoma, three cases of mediastinal form, an alimentary and an extranodal form, respectively. Radiographic findings were enlarged cranial mediastinal lymph node, sternal lymph node, and tracheobronchial lymph nodes on thorax and hepatomegaly, splenomegaly, and enlarged sublumbar lymph nodes on abdomen. Ultrasonographic findings revealed enlarged abdominal lymph nodes and multifocal hypoechoic lesions on the liver. Especially, severe wall thickness of small bowel was observed in a dog with alimentary lymphoma. Three dogs were dead during chemotherapy, and three dogs were dead without any treatment. Three dogs did not return and two treated dog showed normal status. Radiography and ultrasonography, although not giving an final diagnosis for lymphoma, are useful for assessment and diagnosis of lymphoma.

This study was performed to find out how the training for overcoming the fear of and adapting to unfamiliar environments and noises, such as exposures at different levels to noises of a helicopter, affected German Shepherd dogs' characteristics to a specific condition. One hundred and nine German Shepherd dogs were tested in this study. There were no significant differences between genders, tasks, experiences boarding a helicopter, tempers and lengths of time spent with the handler in fearful scores. The dogs at different ages showed significant differences in their fearful scores at the time of the arrival of the helicopter(p<0.001) and approaching to it(p<0.01). In conclusion in the cases of the German Shepherd dogs, there's a need to re-examine the existing training methods for overcoming the fear of and adapting to unfamiliar materials and noises.

Two dogs were referred due to vomiting, depression and anorexia after ingestion of xylitol gum. Both dogs were presented with hepatic failure and one dog had concurrent renal failure. Aggressive supportive treatment was performed, but these dogs died. Necropsy of one dog revealed acute hepatic necrosis, severe renal damages, and hemoperitoneum. This case report demonstrates potential hazard of xylitol toxicity for dogs with clinicopathological and pathological findings.
