The purpose of this study was carried out an epidemiological survey on the prevalence rate of the canine heartworms in Seoul City and the districts of Pa-Ju, Seong-Nam and Po-Chon in Kyonggi province of Korea from September 1994 to the end of September 1995. The blood samples from 292 male and 193 female dogs (pet, 363 ; fighting dogs, 60 ; working dogs, 62) were examined for the adult heartworms cuticle antibodies using the enzyme-linked immunosorbent assay (ELSA) kits. The test was designed to detect the antibodies of the host against the specific cuticle antigens produced with the adult heartworms.

The objective of this study was to investigate the effect of different slag silicate fertilizers on rice by determining the changes in available SiO2, absorbed amount of silicate. Silicate use efficiency, and milled rice yield at Jeonbug series in Honam plain area from 1990 to 2001. The content of 0.5 N-HCI extractable SiO2 in iron refinery slag silicates followed in order of precedence (from lowest to highest); granular quenched slag (GQS), powder quenched slag (PQS), powder air-cooled slag (PAS). And PQS had the most excellent fineness. Absorbed amounts of T-N, K2O in grain and straw of rice increased with the application of silicate fertilizers. By application of silicate fertilizer, the absorbed amount of silicate in rice straw increased by 165, 139, 153 kg ha-1 in GQS, PQS, PAS formulation types as compared with control (704 kg ha-1), respectively. However, the differences of these formulations did not showed the significance as 843~869 kg ha-1. The absorbed amount of silicate in grain also increased by 15~21 kg ha-1 as compared with control (196 kg hi-1), however, it was not differences according to formulation types. Silicate use efficiency was the highest in PQS (42.2%) and the lowest in GQS (27.1%) at the first year, and at the second year, it increased by 44.9 and 35.4% in PAS and GQS but decreased to 24.7% in PQS. In case of PAS which maintained at the first and second years and decreased a little at the third year, it showed small variation than others for the silicate utilization. The number of spikelet per square meter of percent ripened grain increased as the increasing of application level of silicate fertilizer. The thousand grain weight of brown rice increased as the increasing of amounts of silicate fertilizer. Milled rice yield increased by 2% in GQS, 5% in PAS and PQS as compared with the control, respectively.

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.
