This study was carried out to compare the residual antibiotic materials in muscles of slaughter cattle and swine from slaughterhouses in Seoul from 2000 to 2001 by EEC-4-plate method, Charm Il and HPLC method. 1. Residual antibiotic materials were detected from 95 samples(0.8%) by EEC-4-plate and 57 samples(10.2%) by Charm Il. The final HPLC method determined the positives are 43(45.3%) and 27(47.3%) respectively. 2. The detection ratios were 45% by EEC-4-plate and 47% by Charm Il. 3. Seventy samples were classified as tetracyclines 56(75.7.4%), sulfonamides 10(14.9%), β-lactam 6(8.1%) chloramphenicol 1(1.4%). Three of them were confirmed to be positive simmultaneously for tetracyclines, sulfonamides and chloramphenicol. 4. The highest residual concentration of chlortetracycline, oxytetracycline, sulfamethazine, sulfadimethoxine, sulfaquinoxaline, penicillin, ampicillin and chloramphenicol were 0.34, 11.29, 68.16, 0.13, 4.0, 0.12, 0.4 and 0.04ppm, respectively.

This study was performed to make helpful standard for discrimination of cows from heifers by uterine and ovarian section inspection. A total of 3,736 heifers and 249 cows were inspected from January to November 2006 in Karak Market Slaughter house. Firstly, it was obvious that non-corpus albicans were observed in almost heifers(3,597/3,736, 96.3%), but there were distinctive corpus albicans in all cows(249/249 100%). Secondly, another evident was that the length and diameter of the horn in uterus was below 30㎜ in 94.5%(3,267/3,736) heifers, but above 30㎜ in 90.4%(225/245) cows, and it was easy to distinguish between right and left horn by difference of size in 87.6%(218/249) cows. Thirdly the diameters of pelvic cavity was below 220㎜ in 96.8%(3,615/3,736) heifers, but was over 200㎜ in 85.1%(212/249) cows. Fourthly another difference was found in second sacrum union condition and 13th thoracic vertebral process`s states. In case of heifers, it was distinctive five lines in each second sacrum, but it was non-distinctive or united in the same each lines of the sacrum in cows. Fifthly in the results of 13th thoracic vertebral colors, the ratio between red color and white color was 7:3 in heifers(3,385/3,736, 90.6%), but that was 2:8 in cows(199/249, 79.9%). Consequently, it was possible to use the method which discriminated cows from heifers by uterine and ovarian section inspection in large scaled field slaughter house.

This study was performed to establish the discrimination of the corpus albicans that were formed after normal parturition and abortion in Holstein, The corpus albicans were obtained from 504 cows and 506 heifers slaughtered in the Agricultural Cooperative`s Livestock Products Joint Market of Seoul City from March 2007 to October 2007. The difference in a gross examination (morphology, fibrogenesis, deposit state, color, and size) among the fixtures that exist in their ovaries was investigated. All of the cows had corpus albicans in their ovaries: 423 cows (83.9%) had less than three corpus albicans, 81 (16.1%) had more than four. In the heifers, however, 463 (91.05%) had no corpus albicans, 39 (7.7%) had one, and four (0.8%) had more than two. In the types of corpus albicans 73.2% of the cows had oval-type, 14.4% had circular-shaped, 12.4% had irregular-type. In the aborted heifers, however, oval-type appeared in 88.6% and circular-shaped appeared in 11.4%, and no irregular-type was found. There was no significant difference in the fibrogenesis and size of corpus albicans between cows and aborted heifers. However, slight difference in the color of the corpus albicans was observed between two types. In conclusion, it is not easy to discriminate by gross examination of ovary between cows and aborted heifers in the slaughter house.

This study was conducted to investigate the prevalence rate for rabies antibody (PRRA) of dogs near the Pukhansan National Park and in some other districts in Seoul Metropolitan city. From April to July 2000, a total of 414 serum samples were taken from dogs for breeding (92), pet dogs (62), and unclaimed/stray dogs (62). Rabies virus antibodies were detected by neutralizing peroxidase-linked assay (NPLA). Of 414 sera tested, 145 (35%) were positive to rabies virus antibody. PRRA in Pukhansan National Park area and in the other districts of Seoul city were 34.8% and 35.4%, respectively. There was no significant difference in the prevalence rate between these two districts. PRRA in pet dogs, unclaimed/stray dogs, and dogs for breeding were 39.5%, 35%, and 27.2% respectively. PRRA in dogs from residential areas, apartments, animal hospitals, and farms were 32.5%, 60%, 35.3%, and 26.7% respectively. Especially, the dogs reared in apartments had a significantly higher seroprevalence (60%) than those in residential or farm areas. PRRA in less than 1 year, 1~<2 years, 2~<3 years, and over 3 years old dogs were 14.7%, 40.4%, 38.4%, and 53% respectively, and overall 35% in the dog population. In addition, we found that dogs less than 1 year of age had lower antibody prevalence than those over 1 year of age. It was concluded that enhancement of vaccination is important in the prevention of the rabies, and that rabies vaccines should not be less supplied than the population of the dog.

To demonstrate the prevalence of Toxocara spp. eggs in public playgrounds in Seoul city, sand samples collected from March to October in 2000 were examined. Of 1,812 sand samples from 302 playgrounds surveyed, Toxocara canis eggs were detected in 38 sands from 22 place(7.3%). Sand samples in public parks were more contaminated (10%) with the eggs than those in apartment complex area(7.1%) and in residential area(6.8%). Toxocara canis eggs were mostly found in sands in the spring and autumn but were not found in summer. To prevent the comtamination of Toxocara spp. eggs in the public places, the control of dogs and cats wandered do out there will be needed.
