Porcine circovirus (PCV) is a small, nonenveloped virus that contains a single-stranded circular DNA genome of about 1.76kb and belongs to the family circoviridae. The PCV-2 has been incriminated as the cause of post-weaning multisystemic wasting syndrome(PMWS), an emerging disease in pigs. In the present study, a PCR assay was applied to detect PCV-2 in tissue samples. The presence of PCV-2 antigen in the porcine tissues was confirmed by indirect immunofluorescence(IIF) with PCV-2 specific monoclonal antibodies. And then DNA extracted from PCV-2 positive tissues was used as a template. One oligonucleotide primer suitable for PCR was selected from a published PCV-2 sequence(Genbank). Amplified PCR product was detected the same fragment lengths of 416bp as a control. Based on these results, it was suggested that the PCR is a simple and sensitive method for support diagnostic purposes.

The purpose of this study was sero-epidemiological survey of porcine reproductive and respiratory syndrom(PRRS) in Dangjin area. 411 samples from 26 pig farms were analyzed by enzyme linked immunosorbant assay (ELISA). The data indicate that 66% of the pigs and 92% of the farms showed sero-positives to the PRRS virus. Sows showed 58% of sero-positive rate and fattening pigs showed 85% of sero-positive rate. The rate of sero-positive in boars was 63%. No significant regional differences were detected in sero-epidemiological survey.

Background: To investigate the best surrogate marker for insulin resistance in the non-diabetic middle-aged population in Korea. Methods: This study was performed from February to April 2003-2005 in adults over 40 years of age living in Chungju City, South Korea, selected by stratified random cluster sampling. We analyzed the data from a total 6,149 non-diabetic subjects that completed a survey consisting of anthropometric measurement and blood chemistry. We defined the highest quartile of the homeostasis model for insulin resistance (HOMA-IR) as the insulin resistant group in our study population. We also analyzed the correlation of various anthropometric (body mass index, waist circumference, waist to hip ratio, waist to height ratio) and biochemical parameters (total cholesterol to HDL cholesterol ratio, non-HDL cholesterol level, triglycerides to HDL cholesterol ratio and level of triglycerides) with insulin resistance using simple and multiple regression analysis for detecting the insulin resistance group. Results: By simple regression analysis, among the anthropometric parameters including the body mass index, waist circumference, waist to hip ratio, waist to height ratio, and the biochemical parameters, including the total cholesterol to HDL cholesterol ratio, non-HDL cholesterol level, triglyceride to HDL cholesterol ratio and triglycerides level, the body mass index was the best surrogate marker for insulin resistance (95% CI 1.215-1.262). The cut-off value of the body mass index was 24.6 kg/m2 (male; 24.7, female; 24.6 kg/m2), with a sensitivity of 62.6% and specificity of 66.9%. Multiple logistic regression analysis for insulin resistance also gave the same results. Furthermore, the cut-off value of the body mass index for the metabolic syndrome as defined by NCEP-ATP III was also 24.1 kg/m2 (male; 24.0, female; 24.2 kg/m2). Conclusions: Our study results suggest that the body mass index was the best surrogate marker for insulin resistance of a non-diabetic population and its cut-off value was approximately 24 kg/m2.
