The study was carried out to investigate the pathogenicity of EHV isolate to hamsters and mice and immunogenicity of experimentally produced. vaccine were evaluated in the horses. Hamsters infected. intranasally with $LC_1$ isolate showed symptoms of nasal discharge, conjunctivitis and body weight loss during the observation period of 12 days after infection, while only slight depression and body weight loss were noticed with mice infected with $LC_1$ indicating that hamsters are more susceptible to the virus. Antibody titer of mice and hamsters were gradually increased to highest level of 1:2560~10240, 1:640~1280, respectively, at 7~12 days post vaccination. Horses immunized against $LC_1$ killed vaccine reached to maximum antibody titer of 1:20480 around 4 weeks after 1st vaccination and declined after 12 weeks post vaccination. No significant antibody increase were detected after 2nd vaccination. Mean body temperature and mean total leukocyte counts remained within normal range and no adverse reaction were noticed after vaccination.

To establish a laboratory animal model for study on development of diagnostic methods for infectious bovine rhinotracheitis virus(IBRV), experimental infection of the virus to rabbits immunosuppressed with dexamethasone(DX) were carried out. Results obtained throughout the experiments were as follows. When lymphocyte activity was measured by lymphocyte transformation to phytohaemagglutinin in parallel with total and differential leucocyte counting, both groups treated with 2.0mg DX once and 1.0mg DX daily showed marked immunosuppression between 5 to 72 hrs. after administration. The degree of suppression of lymphocyte activities was more remarkable in the latter group. IBRV PQ7 strain at $10^{7.5}\;TCID_{50}/0.2ml$ was inoculated into conjunctival sacs of rabbits immunosuppressed with DX and non-treated. During 3 weeks observation, the immunosuppressed groups revealed mild conjunctivitis, viremia and virus recovery by 33.3 to 100%, whereas the DX nontreated group showed viremia and virus recovery with no clinical conjunctivitis by one of three rabbits(33.3%). In conclusion, it was indicated that experimental infection of IBRV PQ7 strain to rabbit was limited in prerequisite to immunologic modification by administration of immunosuppressive drugs.

This study investigated the status of soft contact lens wear in college students. The results were as follows: 1. The most prevalent age of initial contact lens wear was 19 years or 20 years, with an age distribution in females from as early as 10 years to 20 years. 2. For almost all subjects, the test clinic for the contact lens wear assessment and purchase of the contact lenses was an optical shop. 3. The main advantage for most male subjects was use for sports, whereas most female subjects used contact lenses for cosmetic reasons. 4. The most common side-effects experienced due to contact lens wear were red eye, foreign body sensation, and eye pain. 5. The most frequently reported eye disease caused by contact lens wear was conjunctivitis, with only few subjects experiencing keratitis. 6. Following treatment for the side effects of contact lens wear, most subjects hoped to re-use the previous contact lenses, some subjects wanted to change to new contact lenses, and others subjects refused further contact lens wear.

The purpose of this study is to investigate allergic diseases related to allergy caused by the exposure to indoor and outdoor sources of air pollution in primary schools. The symptoms questionnaire of allergic diseases based on the International Study of Asthma and Allergies in Childhood (ISAAC) was completed by the participants. The past and present status of asthma, allergic rhinitis, eczema, and allergic conjunctivitis were investigated by providing a questionnaire to all the participating children. Questionnaires were sent to a total of 61,350 children from 438 primary schools. A total of 40,522 children responded to the questionnaire, which represents a 66.1% return rate. Volatile Organic Compounds (VOCs), $\underline{A}$ldehydes, and Particulate Matter ($PM_{10}$) were measured and analyzed from October to December of 2006, in 82 primary schools. The final study population comprised 35,168 children with complete data which excluded incomplete questionnaire responded by 5,354 children. Based on the survey, the level of indoor air contamination did not appear to be high, but 27.2% of the schools evaluated had exceeded the $PM_{10}$ level specified by the school health guidelines ($100\;{\mu}g/m^3$). The overall mean concentration of formaldehyde was $22.07\;{\mu}g/m^3$ and 1.0% of schools (1 school) exceeded the $100\;{\mu}g/m^3$. Statistically significant relationships have been observed between indoor air quality and prevalence rate of allergic rhinitis and conjunctivitis of primary schools in Korea.

This study was conducted to determine the cause and prevalence of occupational skin disease in dental technicians working in Seoul, Korea. and to investigate the relation between these work condition and skin disease of the hand, wrist and forearm. This study was based on the Nordic occupational skin questionnaire(NOSQ), a self-administrated questionnaire which was modified to investigate the dental technician's occupational factors in domestic circumstances. The number was distributed to 500 dental technicians who participated in annual continuing education for dental technicians of the Seoul metropolitan area in April 2006. Of the subjects, 62(30.4%) had eczema and 70(32.9%) had urticaria, as diagnosed. Of the subjects with the symptoms of urticaria, 30 complained of atopic dermatitis, 65 complained of allergic rhinitis, 56 complained of allergic conjunctivitis, and 18 complained of asthma. The group with atopic history had a higher frequency of eczema or urticaria than the group without atopic history. From multiple regression analysis, the group who had a history of atopic dermatitis also had high symptom rates of eczema. The group who had a history of allergic rhinitis and allergic conjunctivitis had high symptom rates of urticaria. The urticaria symptom rates were higher in those wearing gloves than those who did not for the type of work.

Background: Chlamydophila felis, formerly known as Chlamydia psittaci var. felis, is frequently associated with ocular, respiratory, and occasionally reproduction tract infections. Even though the infection is sometimes asymptomatic, it potentially results in a latent immunosuppressive infection. Objective: This study aimed to identify occurrences of feline chlamydophilosis, rarely reported in cats in Indonesia. Methods: The observation was conducted in three cats with clinical signs of Cp. felis infection, particularly relapsing conjunctivitis. The cats' histories were recorded based on owners' information. Conjunctival swabs were sampled for cytology examination and molecular assay detection. A phylogenetic tree was generated using MEGA-X software to reveal group clustering. A post-mortem examination was performed on the cat that died during an examination. Results: Cp. felis was detected in both cytological examination and polymerase chain reaction assay. The phylogenetic tree demonstrated that the Cp. felis isolated in this study clustered with several other isolates from the other countries. Cp. felis can be isolated from cats with different clinical manifestations and levels of severity. The chronic fatal infection demonstrated interstitial broncho-pneumonia under histopathological examination. Conclusions: Molecular assay of Cp. felis is always recommended to obtain a definitive diagnosis of feline chlamydophilosis since the disease can have various clinical manifestations. Even though it may be subclinical and is often not fatal, an infected cat may be a carrier that could spread the pathogen in the surrounding environment. Serious disease management is suggested to avoid high costs associated with regularly relapsing disease.

A survey was performed on the outbreak of listeriosis in a Korean native goat in Animal Breeding Station of Gyeongsang National University, Chinju, Korea. Clinical signs in the affected goat were fever, dullness, inappetence, nasal discharge, slobbering, dysphagia, circling, incoordination, recumbency, unilateral facial paralysis, torticollis, dyspnea, spasmodic paddling movement of the limbs and death at 6 days after onset. No significant gross lesions were seen. The histopathological lesions were consisted of perivascular edema and cuffs by round cells and microabscess with infiltration of neutrophils, lymphocytes and macrophages in the cerebrum. Gram-positive organism was observed in the microabscess lesions. Listeria monocytogenes was isolated exclusively from the brain tissue by cultural examination and the lesions induced by experimental infection with the isolate were characterized by severe conjunctivitis in rabbit and hepatic necrotic foci in mouse. This seems to be the first report of listeriosis in Korean native goat.
