The objective of this study was to evaluate the efficacy of an imidacloprid 10% and flumethrin 4.5% polymer matrix collar against the developmental stages of Haemaphysalis longicornis infesting dogs using the hair from treated dogs in a semi-in-vitro assay set. When incubated with 0.5 g of the hair collected from the dogs installed with the drug-embedded collar after 10 days, average death rate of the larval, nymphal, and adult H. longicornis was 21.5%, 77.9%, and 100% at 30 min, 1 hr, and 2 hr, respectively. This study showed the larval stages as well as the nymphal and adult stages of H. longicornis ticks are killed upon contact with the hair from dogs treated with the collar within 2 hr.

Tracheal collapse is a common respiratory disease in dogs. There are many ways to treat tracheal collapse, one of which is the use of an intraluminal stent. In this study, we divided 21 dogs into two groups and implant conventional stents and new nitinol stents. Comparison of two groups was based on following, feature of stent fracture, form of stent migration, clinical sign improvement, complication and prognosis. Approaching was established via C-arm under spontaneous breathing and placing a stent at the site of collapse. Using radiographic images, determine stent size accurately. For a comparison of identical condition, all intraluminal stents were placed 10 mm caudal from larynx to 10 mm cranial from carina. In this study, new nitinol stents improve the problems of conventional stents and may be effective in the treatment of tracheal collapse in small dogs.

The purpose of this study was to evaluate the clinical and imaging characteristics of canine splenic tumors and to establish guidelines for the presurgical assessment of splenic tumors in dogs. Fifty-seven dogs that underwent total splenectomy for the treatment of splenic tumors were evaluated by examining medical records, hematologic results, diagnostic imaging results, and histopathologic results. The maximum lesion size from ultrasonography was significantly different between malignant and benign tumors (p = 0.002). There was a correlation between tumor margination and type of splenic tumors (p = 0.045). Precontrast lesion attenuation on computed tomography was significantly different between splenic malignant and benign tumors (p = 0.001). The mean ${\pm}$ SD precontrast lesion attenuation of malignant tumors was $40.3{\pm}5.9$ Hounsfield units (HU), and for benign tumors, it was $52.8{\pm}6.8HU$. In conclusion, some variables of the imaging examination could be used to distinguish the type of splenic tumor. Based on the study results, using a diagnostic flowchart would be effective in increasing the survival rate of patients with splenic malignant tumors. In addition, fine needle aspiration or magnetic resonance imaging prior to surgical exploration and histopathologic examination may be useful in achieving a more accurate diagnosis.

In three dogs showing cerebellar ataxia, the onset of clinical signs varied from a young age of five months to age 13 years. Qualitative magnetic resonance imaging (MRI) revealed various degrees of cerebellar atrophy, and a tentative diagnosis of cerebellar cortical degeneration was made. Quantitative analysis using the brainstem to the cerebellar cross-sectional area ratio (BS:CBM ratio) and T2-signal intensity histograms were obtained to perform an objective evaluation. These techniques have the advantage of being easy and fast to evaluate. These quantitative analyses revealed the severity of cerebellar cortical degeneration in the three dogs as mild, moderate, and severe. Dogs 2 and 3 were identified as abnormal on the relative cerebrospinal fluid (CSF) space using T2-signal intensity histograms but were normal on the BS:CBM ratio. This suggests that the T2-signal intensity histograms may have higher sensitivity than BS:CBM ratio.

Two dogs presented with bilateral pattern-forming corneal opacity. Treatment with topical immunosuppressants was initiated after a complete ophthalmic examination. The response to treatment was assessed by analyzing serial images using slit-lamp biomicroscopy and spectral domain optical coherence tomography (SD-OCT). Both dogs responded to topical immunosuppressants; however, the lesions recurred once the treatment was abated or withdrawn. The most effective immunosuppressant in both dogs was 0.03% tacrolimus ointment. Early and continuous treatment with topical immunosuppressants may be necessary to improve corneal clarity and prevent scarring. SD-OCT could provide useful structural information regarding presumed immune-mediated keratitis and aid in monitoring treatment response.

A total of 1,024 sera were collected from cattle(227), pigs(465), chickens(257) and dogs(75) raised or slaughtered in Daejeon metropolitan city from April to September 2002. Japanses encephalitis virus(JEV) antibodies in sera were detected by the haemagglutination inhibition test. The prevalence rates of JEV antibodies were 99.1 %, 54.0 %, 63.0 % and 98.7 % in cattle, pigs, chickens and dogs, respectively. In case of cattle and dogs, the monthly antibody-positive rates were as high as 85.7∼100.0 % and there were no differences among six months. In case of pigs, the monthly antibody-positive rate showed the lowest in April(6.4 %) and the highest in July(100.0 %) and it remained above 50 % during the summer-time. In case of chickens, the monthly antibody-positive rate was 100.0 % in July & August, 80.5 % in June, 40.0 % in May, 7.5 % in September and 5.0 % in April in order and there were distinct differences in seasons.

A preliminary survey for classification of coccidia isolated from domestic animals and poultry was broadly conducted by the morphological aspects of the $o{\ddot{o}}cysts$. The number of animals and birds used in this survey were 762 chickens, 30 rabbits, 37 goats, 18 swine, 39 cattle, 8 dogs, 132 ducks, 23 deer and 15 horses.

The effects of continuous administration of tiletamine-zolazepam(T-Z) on the blood, liver and kidney of dogs were evaluated. The drug was repeatedly administered into ten mongrel dogs intramuscularly at dose of 10mg/kg for every seven days. Hematology(PCV, WBC, RBC, TP, Fibrinogen) and serum chemistry(ALT, AST, BUN, Creatinine) were monitored for 14 days postinjection. No significant changes in PCV values, total RBC counts and plasma total protein values was found. Total WBC counts and fibrinogen values were significantly increased from 2 days to 7 days postinjection. There was no significant change in ALT, AST, BUN and creatinine levels. All animals were euthanized and necropsied at 14 days postinjection. No gross lesion and pathologic lesion was found on liver and kidney in necropsy finding.

Clinical usefulness of somatosensory evoked potentials (SSEP) as a prognostic tool was evaluated with three dogs showing clinical signs associated with intervertebral disc diseases. Prior to measure SSEP, history taking, physical examination, radiological study and neurological examination were performed. In case 1, poor prognosis was predicted because deep pain was not observed and loss of sensory function was observed in SSEP. And the clinical signs persisted with the conservative treatment. However, in cases 2 and 3, good prognoses were predicted by normal conduction velocity in SSEP that meant the presence of sensory function. The clinical signs of cases 2 and 3 disappeared at days 18 and 13 after treatment, respectively. These results suggest SSEP be used clinically as a prognostic tool in dogs with intervertebral disc diseases.
