Background : Enterococci are important cause of nosocomial infections. Recently, vancomycin-resistant enterococci (VRE) has been increasingly reported as significant nosocomial pathogens. Therefore, accurate identification of enterococcal species is a prerequisite step for the appropriate antibiotic treatment and epidemiologic surveillance. We wanted to know the usefulness of PCR method compared with Vitek automatic identification system. Methods : Totally 105 isolates were identified on the species level by Vitek (GPI card and software version R06.1), methyl-α -D-glucopyranoside test, and PCR methods. Results : Among 105 enterococcal isolates, 59 were identified as E. faecium, 11 E. faecalis, 6 E. gallinarum by Vitek. But 29 isolates (28%) were unidentified. Subsequently all of these isolates were analyzed by PCR, the results of which were as follows : 17 E. faecium, 5 E. casseliflavus, 7 E. gallinarum. Two isolates identified as E. gallinarum by Vitek were reidentified as E. casseliflavus by PCR and other methods far phenotypic characterization. Conclusoin : PCR method was more accurate and sensitive than Vitek for the identification of enterococci species. (Korean J Infect Dis 33:123∼127, 2001)

The <Cheong-San-Pyol-Gok> is the best prominent masterpiece of Songs and Poems of Koryo. And it has obtained good results than any other Koryosokyo. In spite of the previously various study, there has been diversities of opinion about word meanings, structure, the problems of presumptive authors, and the theme. We have had difficulty in analyzing the content and the theme because we have a little bibliography about <Cheong-San-Pyol-Gok> and the author and the written date was not known. There are four steps in composition (i.e. the introduction. the development of the theme, conversion and summing up) in side of structure, flowing of a poetical imagination and there are three parts in side of moving space. Finally I am proud of researching this work. I am sure that <Cheong-San-Pyol-Gok> is the best prominent masterpiece as though the author and the written date was not known.

This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.

Background: Relative tumor density (RTD) has been a standard method to compare skin cancer distribution by anatomical sites. RTD is a flawless tool to analyze soft tissue sarcoma (STS), a group of heterogenous malignant neoplasms with whole-body distribution. Objectives: This study aims to analyze RTD of STS in Korean cohort and provide a solid foundation to approach STS from different body sites. Methods: The biopsy data of 40 patients and a total of 41 sarcoma lesions was analyzed. RTD was calculated by dividing the proportion of tumors at a defined anatomical site by the mean proportion of the skin surface area. Body was classified into four anatomical sites of head and neck, trunk, upper limbs, and lower limbs. Results: Mean age of 26 men and 14 women was 64 years. The most commonly diagnosed sites of 41 lesions were lower limbs (n=16, 39.0 %) and trunk (n=12, 29.3 %). The sites with the highest RTD were head and neck (n=11, 2.98) and lower limbs (n=16, 0.98). The most common tumor in head and neck area was cutaneous angiosarcoma (n=7, 63.6 %). In terms of tumor type, Kaposi’s sarcoma (n=14, 34.1 %) was the most common, followed by dermatofibrosarcoma protuberans (n=12, 29.3 %). Conclusion: The concept of RTD paves the way to approach soft tissue sarcomas which show histological and topographical complexity.
