The present study has been performed to develop a PCR technology to identify human immunoglobulin(Ig) allotypes with restriction fragment length polymorphism(RFLP) using a probe. Genomic DNA were ampilified with PCR tecnology using primers from peripheral blood lymphocytes of 10 periodontal patiens, whose Ig allotypes have been pre-determined by serological tecnique using heagglutination technique. The result indicated that the RFLP patterns could successfully differentiate the Ig allotypes, which suggests that this technology can be developed as a tool useful for population genetics studies.

BACKGROUND: Direct antigen test (DAT) and culture are primary tests to diagnose infections by respiratory viruses, but are mainly available for the traditional viral pathogens such as respiratory syncytial virus (RSV), influenza virus, parainfluenza virus (PIV), and adenovirus in clinical laboratories. The objective of this study was to evaluate a multiplex reverse transcriptase-PCR method using Seeplex(TM) RV Detection kit (Seegene, Korea) for the detection of rhinovirus, coronavirus, and human metapneumovirus (hMPV). METHODS: From January to May 2007, nasopharyngeal aspirates (NPAs) from pediatric patients negative for culture and DAT of traditional viral pathogens were tested with Seeplex(TM). All the amplicons were directly sequenced and homology of the sequences was searched in the National Center for Biotechnology Information (NCBI) database. Patients' medical records were reviewed for clinical and demographic features. RESULTS: Forty-seven (26.4%) of 178 NPAs were positive: 18 rhinovirus, 15 hMPV, 4 RSV A, 3 coronavirus OC43, 3 influenza virus A, 2 adenovirus, 1 coronavirus NL63, and 1 RSV B. Based on maximum identity, each of the sequences indicating rhinovirus, hMPV, and coronavirus OC43 matched to the corresponding viruses with homology of 94-98%, 96-99%, and 98-100%, respectively. Seeplex(TM) positive patients were 0-11 yr old with a male:female ratio of 1.5:1. Clinical diagnoses included 9 pneumonia, 6 bronchiolitis, 2 cold, 1 asthma exacerbation for rhinovirus; 10 pneumonia, 4 bronchiolitis, and 1 clinical sepsis for hPMV; and 1 pneumonia, 2 croup, and 1 cold for coronavirus. CONCLUSIONS: Multiplex reverse transcriptase-PCR method using Seeplex(TM) RV Detection kit is a reliable test to detect rhinovirus, hMPV, and coronavirus. It may improve the diagnostic sensitivity for RSV, influenza virus, PIV, and adenovirus.

Quantitative measurement of BK virus DNA (Q-BKDNA) has been used for the early diagnosis and monitoring of BK virus-associated nephropathy (BKVAN). This study was designed to determine the BKDNA cutoff for the diagnosis of BKVAN. Between June 2005 and February 2007, 64 renal transplant recipients taken renal biopsies due to renal impairment submitted plasma and urine for Q-BKDNA. Eight BKVAN patients (12.5%) had median viral loads of 6.0 log(10) copies/mL in plasma and 7.3 log(10) copies/mL in urine. Among 56 non-BKVAN patients, 45 were negative for Q-BKDNA; 4 were positive in plasma with a median viral load of 4.8 log(10) copies/ mL, and 10 were positive in urine with a median viral load of 4.8 log(10) copies/mL. Receiver operating characteristic curve analysis showed that a cutoff of 4.5 log(10) copies/mL in plasma and a cutoff of 5.9 log(10) copies/mL in urine had a sensitivity of 100% and a specificity of 96.4%, respectively. A combined cutoffs of 4 log(10) copies/ mL in plasma and 6 log(10) copies/mL in urine had better performance with a sensitivity of 100% and a specificity of 98.2% than each cutoff of urine or plasma. QBKDNA with the combined cutoffs could reliably diagnose BKVAN in renal transplant recipients.

BACKGROUND/AIMS: Partial hepatectomy is considered as best treatment for selected HCC patients combined with liver cirrhosis. We conducted this study to assess the safety and effects of partial hepatectomy for HCC combined with liver cirrhosis and to identify the prognostic factors. METHODS: Retrospective analysis was performed for 115 HCC patients with liver cirrhosis who underwent hepatectomy in Korea Cancer Center Hospital from 1987 September to 2002 July. Median follow-up period was 30 months. RESULTS: In-hospital mortality rate was 0.87% (1/115 cases). 5-years overall and disease free survival rates were 59.3% and 44.75%, respectively. Fifty three patients developed recurrence and most common recurrent site was remnant liver (81.1%) and 3-year survival rate after recurrence was 33.4%. Independent prognostic factors for overall survival rate were TNM stage, multiplicity and venous invasion (p<0.05). CONCLUSION: Hepatectomy plays a significant role for HCC with compensated liver cirrhosis and is regarded as the effective treatment with acceptable mortality. However, recurrence rate is still high, so frequent follow-up study should be needed for early detection of recurrence amenable to effective treatment. For the high risk patients, further study should be followed to reduce the recurrence after hepatectomy, including surgical technique and adjuvant treatment.
