An indirect immunofluorescent antibody test was applied to survey the antibody prevalence on five canine viruses including canine distempervirus(CDV), canine parvovirus(CPV), canine coronavirus(CCV), canine adenovirus type-2(CAV-2), canine parainfluenzavirus(CPIV) in dogs. The period studied was from October 1992 to June 1993. A total of 80 dog sera was collected from veterinary clinics in Kwangju and Seoul, and examined for the presence of virus antibodies. Immunofluorescent antibodies(IFA) to all viruses were present in a high percentage of 80 sera tested. Seventyfive(93.8%) showed detectable IFA against CPV, 67(83.8%) against CDV, 51(63.8%) against CCV, 42(52.5%) against CPIV and 34(42.5%) against CAV-2. These suggested that all viruses were endemic in the communities. IFA levels against each virus were also distributed fairly irregularly. IFAs for CDV and CPV were detected more frequently with a relatively high incidence in vaccinated group less than 1 years of age. IFAs for CAV-2 were detected more frequently with growing age. In the correlation of clinical signs and antibody prevalence, dogs that showed hematochezia and vomiting had high titers in the positive sera is noteworthy, particularly for CDV and CPV. The significance between dogs those who had diarrhea, dyspnea and salivation and those viruses were obscure.

Upper canine is described as 'cornerstone' of maxilla, and its importance is implicated by long root and good alveolar support. The incidence of impaction of upper canine is the second most frequent next to the third molar because it takes a long period of time to develop, and has a complicated path of eruption, and erupts lately. Generally, the patient who has a palatally impacted canine visit the clinic primarily due to a missing of canine after 12-13 years old. Palatally impacted canine is different from labially impacted canine in its cause and treatment process. It is due to malposition or anomalous lateral incisor rather than arch length deficiency. Once the impaction is identified, the first stage of the treatment is to localiz the lesion by radiographic examinations or others and according to severity, orthodontic traction, or transplantation should be considered, and comprehensive diagnosis and treatment plan of malocclusion should be estsblished. Properly managed impacted canine can provide funtion and esthetic through proper diagnosis and treatment of extraction of canine is not indicated.

This study was performed to determine the etiological agents in concurrent disorders in gastrointestinal and respiratory tract. Most of dogs had clinical signs including nasal and ocular discharge, coughing, vomiting, and diarrhea. Of the 22 dogs, seropositive rates of each virus were 54.5% (12/22) against canine distemper virus, 90.9% (20/22) against canine adenovirus 1, 36.4% (8/22) against canine adenovirus 2, 18.2% (4/22) against canine parvovirus, 81.8% (18/22) against canine hepatitis virus and 59.1% (13/22) against canine coronavirus. Canine distemper virus and canine parvovirus infection were 54.6% (12/22) in histopathological examination. In addition, mixed infections of canine distemper virus and adenovirus 2 were 9.1% (2/22). While simple infection of canine adenovirus 2 were 9.1% (2/22). E coli and Staphylococcus spp were isolated in facts as a rate of 72.7% (16/22) and 40.9% (9/22), respectively. Conclusionally, it is also estimated that environmental stress might be one of the causative factors.

To predict eruptive path of maxillary canine, 13 male and 11 female malocclusions were longitudinally studied for 4 years. And to study frequency and distribution of impaction of maxillary canine, 1500 malocclusions were studied. The path, velocity and duration of maxillary canine eruption were determined by periodic angular and linear measurement using periodic orthopantomograms and cephalograms. The following results were obtained. 1. Maxillary canine was erupted with $14.5^{\circ}$ distal tipping from initial stage $98.1^{\circ}$ to final stage $83.6^{\circ}$ of axial inclination on orthopantomogram. 2. Eruptive velocity of maxillary canine was fastest on stage 4, and mean eruptive velocity was 10.5mm per year on stage 4. 3. Eruption of maxillary canine was completed 12 year 5 months in male and 11 years 8 months in female. 4. To predict the duration for eruption completion by position of maxillary canine on cephalogram, regression equation was obtained. 5. Frequency of impaction of maxillary canine was 1.47% in malocclusion and more frequent in male. Distribution of buccal and palatal, right and left impaction was no different, but unilateral impaction was more frequent.

For the monitoring of six viral disease (CIV: canine influenzavirus, CPIV: canine parainfluenzavirus, CHV: canine herpesvirus, CPV2: canine parvovirus type 2, CCoV: canine coronavirus, CNV: canine norovirus) inspections, a total of 300 samples were collected nasal or feces from the companion dogs of animal hospital (n=98) and the abandoned dogs of animal shelters (n=202) in Gwangju, Korea. Using PCR and RT-PCR, CPV2, CPIV and CHV were detected in 55 (18.3%), 11 (3.7%), 1 (0.3%), respectively. CPV2 was highly detected in May, October and November. and CPIV was highly detected in November. But those agents were not detected the virus in March and July. Based on the results of the investigation continuous monitoring for companion and abandoned dogs will be required.

The dog frontal sinus may represent an alternative model dental implant research; its topographical resemblance to the maxillary sinus renders it a potentially favorable experimental environment. The aim of this study was thus to elucidate the anatomical configuration of the canine frontal sinus and histological characteristics, and to determine whether it could be a new canine experimental model for dental implant research. Twenty-four sides of canine frontal bones were harvested. The distance from the nasion to the emerging point of the lateral aspect of the canine frontal sinus was measured with the aid of Lucion software. The thicknesses of the canine frontal sinus wall were measured, and the two specimens stained with hematoxylin and eosin. The mean distance from the nasion to the emerging point of the lateral aspect of the canine frontal sinus was 16.0 mm. The mean thicknesses of the canine frontal bone at 3, 6, 9, 12, and 15 mm lateral to the midsagittal plane were 2.3, 2.7, 3.2, 3.8, and 3.7 mm, respectively. The canine frontal sinus was lined with pseudostratified ciliated columnar epithelium. These data suggest that the canine frontal sinus is a suitable alternative to the canine maxillary sinus as a model for studying various sinus augmentation protocols.

Permanent canine are very important teeth in point of function as well as esthetic. Therefore impaction of canines is a frequently encountered clinical problems. The incidence of impaction ranges between 1-3%. The cause of canine impaction can be result of ectopic position of tooth germ, defect of dental follicle, early loss or delayed exfoliation primary canine, space problem, supernumarary teeth, cyst, odontoma, Impaction frequently involves further complication such as root resorption of adjacent teeth, cyst formation and migration of the neighboring teeth. Various treatment modalities include extraction of primary canine, surgical opening and orthodontic traction, autotransplantation, surgical extraction of impacted canine.

Endometrial tissue is a known source of mesenchymal stem cells (MSCs). We isolated canine endometrial stem cells from canine endometrial tissues using an enzymatic method and confirmed the immunophenotype of mesenchymal stem cells and multilineage differentiation. Canine endometrial tissues were obtained from canine ovariohysterectomy surgery and isolated using 0.2% collagenase type I. We measured the immunophenotype of stem cells using flow cytometry. To confirm the differentiation ability, a trilineage differentiation assay was conducted. In this study, canine endometrialderived MSCs (cEM-MSCs) were isolated by enzyme treatment and showed a spindle-shaped morphology under a microscope. Moreover, cEM-MSCs showed a trilineage differentiation ability. In this study, the canine endometrium was a good source of MSCs.
