Canine sarcoptic mite (Sarcoptes scabiei var. canis) is ectoparasite which burrow usually in the stratum corneum of the skin of dogs. Antigens from the burrowing mites induce humoral and cellmediated immune responses in the hosts. The effect of antigenecity induced by somatic antigens of house dust mite (Dermatophagoides pteronyssinus) isolated by continuous elution has been evaluated in canine sarcoptic mites infestation. Continuous elution was carried out in 7.5% SDS-PAGE to isolate proteins of common antigens from somatic antigens of house dust mite.

To assess anesthetic depth using quantitative electroencephalography (q-EEG), we recorded processed EEG (raw EEG) till 100 minutes in beagle dogs anesthetized for 60 minutes with tiletamine/zolazepam (n=5, TZ group), xylazine/ketamine (n=5, XK group) and propofol (n=5, PI group) by intermittent bolus injection. Raw EEG was converted into 95% spectral edge frequency (SEF) and median frequency (MF) through fast fourier transformation (FFT) method. 95% SEF value of TZ group was significantly higher (p less than 0.05) than the XK group from 10 minutes to 100 minutes. 95% SEF value of PI group was significantly higher (p less than 0.05) than the XK group from 10 minutes to 40 minutes, and significantly low (p less than 0.05) than XK group at 90 and 100 minutes.

In order to study about the lobule and layer formation and cell migration of the mouse cerebellum from at the birth to 15th day effected by 2.5, 5 and 10 Gy r-raddiation at the 19th pregnancy. The routine tissue preparation and staining procedure, Immunohistochemical staining method by the several antibody and western brotting method were utilized from the birth to the 15th day. The results were as followings. 1. The body and cerebellum weights were more slowly increase of the the 2.5 Gy, 5 Gy and 10 Gy irradiation group compare to the control group, and the health condition of the 2.5 Gy group was a little bad. but the 10 Gy group was more severe and begun to die from the 12th day after birth.

Proteomics is a useful approach to know protein expression, post-translational modification and protein function. We investigated the protein expression pattern and identity in chickens fed with the tissue culture medium waste after harvest of Korean wild ginseng (TCM-KWG) (Panax ginseng). Two groups (n=60/group) of day old broiler chickens were administered with 0 (control) and 0.8% (treatment) TCM-KWG through drinking water. After 5 weeks, we examined the protein expression pattern of fibularis longus and superficial pectoral muscle by Two-dimensional electrophoresis analysis. Interestingly, TCM-KWG treatment significantly increased five spot's density, and markedly reduced five spot's density in the muscles.

This study was carried out to investigate the antibiotic resistance pattern of Enterococcus spp. and Staphylococcus aureus (S. aureus) isolated from chicken feces. All isolates showed high resistance to erythromycin (E) and tetracycline (TE). Of the 63 Enterococcus faecalis (E. faecalis) isolates, 73.0% were resistant to E and 98.4% to TE. Of the 44 Enterococcus faecium (E. faecium) isolates, 50.0% were resistant to E and 95.5% to TE. Of the 52 S. aureus isolates, 57.6% were resistant to E and 96.2% to TE. The prevalence of two and three drugs resistance pattern were 28.6% and 17.5% of E. faecalis, 40.9% and 25.0% of E. faecium and 38.5% and 23.1% of S. aureus, respectively.

An immunochromatographic (IC) strip for the rapid detection of Salmonella spp. in the enriched sample was developed. Affinity purified Salmonella polyclonal antibody was conjugated with 40 nm colloidal gold particles which were prepared by citrate method in our laboratory. The antigen-antibody-gold complex was captured by Salmonella antibody attached to test line of nitrocellulose membrane during the capillary migration of sample. Specificity of the IC strip was calculated to be 100% (12/12) and sensitivity was 97.6% (41/42) in the test with pure cultured bacteria. Salmonella was artificially inoculated into raw pork macerated with enrichment broth.

Canine coronavirus (CCV) causes a mild gastroenteritis in dogs. The virus is highly contagious. Although the virus was isolated more than thirty years ago, canine coronavirus infection continues to be a widespread problem. Mixed infections with both CCV and canine parvovirus (CPV) are common. Four kinds of commercial killed CCV vaccines are available in Korea. All the commercial vaccines should pass the National Assay for Veterinary Biologicals prior to release. For the potency test of CCV vaccine, it is necessary to use CCV antibody free dogs. The test requires not only kennels but high cost. To develop easy, efficient and economic potency test method for killed CCV vaccine using laboratory animals, a series of experiments with rabbits and guinea pigs were carried out in this study.

This experiments was designed to observe the effect of period and dose of ingestion of grapes on renal failure in dog. After the dogs had been mixed of general feed, raisins from U.S.A and fresh grapes from Chile selling in Korea. We observed the clinical sign, and analyzed the blood and urine using by biochemical test. The experiment was executed by the two following groups. The experiment group 1. derived renal failure by supplying the mixed general feed with fresh grapes and dry grapes 15 g per weight kg, 2 times a day (AM 09, PM 21), the experiment group 2. executed to derive renal failure by supplying the mixed general feed with fresh grapes and dry grapes 40 g per weight kg, 2 times a day.

The present experiment was performed in order to know the anti-emetic effect of acupuncture, aquapuncture with metoclopramide and moxibustion on the xylazine induced emesis in dogs. The animals were devided into a control group (non-acupoint) and two experimental groups (BL-20 and LIV-13), respectively. Acupuncture, aquapuncture with metoclopramide (1 mg/kg) and moxibustion were applied to animals for 20 minutes before xylazine injection (2.2 mg/kg, IM). In acupuncture group, the emetic rates in BL-20 (16.7%) and LIV-13 (16.7%) were lower than that of control group (50%), respectively. In aquapuncture group, the emetic rates in BL-20 (16.7%) and LIV-13 (0.0%) were lower than that of control group (50%), respectively.

Olive flounder (Paralichthys olivaceus) is the major mariculture fish in Korea. The annual aquaculture production of olive flounder in Korea during the period of 2003 was 300,000 ton (2002 Statistics, Ministry of Maritime Affairs and Fisheries, Korea Government). Anesthetics is very necessary in aquaculture to minimize stress and damage during harvesting, grading, transportation, spawning induction and handling to fish. In the present study, isoeugenol as new anesthetic in marine fish, especially olive flounder, was examined to know the efficacy and proper concentration. As a result, olive flounder adult was exhibited sedation at 5 ppm at 10 and 15℃, and 7.5 ppm at 20℃, respectively.
