BACKGROUND: The polymerase chain reaction(PCR) assay is rapid, sensitive analytical technique but has problem of high false-positive rate. We applied dUTP-UDG PCR (dU-PCR) method to prevent carryover contamination major source of high false positive in PCR assays, for detection of Mycobacterium tuberculosis. METHODS: The PCRs for detection of M. tuberculosis were performed with P1 and P2 primers based on IS6110 repeated sequence. FTC-2000 was used for capillary PCR and Uno-Thermoblock was used for heating block PCR. In order to evaluate the effect of dU-PCR controlling carryover contamination, PCRs were performed in the presence of UDG and the absence of UDG. To compare the sensitivity of usual dT-PCR with dU-PCR, chromosomal DNA of M. tuberculosis ranging 500pg to 0.5fg were amplified by dT-PCR and dU-PCR method using two different thermocycler, capillary and heating block type, respectively. RESULT: The dU-PCR using UDG prevented carryover contamination by amplicon DNA up to 500pg. By capillay PCR method, the lower limits of detectability of dT-PCR and dU-PCR were 0.5fg and 500fg, respectively, which indicates the sensitivity of dU-PCR was lower than dT-PCR. But by heating block method, the lower limits of detectability of both method of dU and dT-PCR were 0.5fg. So the sensitivity of dU-PCR was same as dT-PCR. CONCLUSION: The dU-PCR by heating-block method was sensitive test for detection of M. tuberculosis that effectively prevent carryover contamination by amplicon.

The three components of taxonomy are classification, nomenclature and identification. Traditionally, bacterial classification and identification were performed based on the morphology and the biochemical data of the bacteria. In newer theories, or so-called natural concepts, the relationships between bacteria are based on the overall similarities of both the phenotypic and genotypic characteristics. The polyphasic taxonomy, or current taxonomy, describes the integration of all of the available genotypic, phenotypic, and phylogenetic information into a consensus type of general-purpose classification. When routine identification methods that are based on the biochemical tests fail, alternative procedures such as complete 16s rRNA gene sequence analysis are required. Although the results of 16s rRNA gene sequence analysis have not been fully discriminatory to differentiate closely related species, they may guide the additional analyses that are required for species identification.

PURPOSE: Nowadays, concern about the care of one's offspring has been increasing due to increased active participation of wornen in society and having fewer children than in the past. Therefore, we performed a study to evaluate the rnajor fields of child care counselling and establish effective child care counselling. METHODS: We retrospectively analyzed 2,754 cases of child care counselling about sex ratio, distribution of age, major fields of concern and major questions of each field using personal computer communication from April 1994 to March 1999. RESULTS: Sex distribution was usually unknown. The most frequent questions concerned the infantile period, especially less than 6 months of age. Nutrition, digestive system, development and psychology were the major fields of child care counsellng. CONCLUSION: We conclude that the major period of child care counselling was during the infantile period, and there was a major concern about nutrition, development and psychology. But, more efforts and studies are needed to establish effective child care counselling.

A 5-year-old boy was admitted to the hospital with a high fever and abnormal gait. Magnetic resonance imaging showed extensive swelling of the quadriceps and adductor muscles around the right hip and anterior thigh. A duplex scan demonstrated a thrombus from the external iliac vein to below the popliteal vein. The blood culture revealed Streptococcus pyogenes. The patient was immediately treated with antibiotics and anticoagulants. Follow-up sonography demonstrated complete disappearance of the venous thrombosis. We report a case of streptococcal myositis complicated by deep vein thrombosis.

College and university foodservice dietitians have to be competent for playing a role as the future food service executive as well as the present foodservice administrator in the promising foodservice industry field. The study conducted a survey to examine training needs corresponding to educational contents for the purpose of helping them acquire a new knowledge related to self-development and duty through educational training. The results of this study suggested that training needs were differed by general characteristics of dietitians, operational characteristics of food services, and training subjects. A future study should develop systematic training strategies for dietitians.

c-erbB-2 oncogene is a normal cellular proto-oncogene coding transmembrane glycoprotein structurally similar to the epidermal growth factor receptor. Amplification of this oncogene in a variety of human adenocarcinomas has been reported and is particularly well documented in breast carcinoma. It has been suggested that amplification of this oncogene is indicative of poor prognosis and is valuable only second to the lymph node status. Using immunohistochemical staining for the c-erbB-2 protein, overexpression of this protein was analysed in 228 primary breast cancer specimens and the frequency of overexpression and the relationship between overexpression and the other established prognostic variables are evaluated. Ninty three cases out of 228 cases(40.8%) show postive oncoprotein overexpression and using the chi-squared test for a trend, a significant correlation was found between c-erbB-2 protein staining and the histological grade, lymph node status, and estrogen receptor status(P<0.05). No significant association was found between staining and the patient's age and tumor size. Most of the tumors with histological types known to have good prognosis showed negative expression. Above findings strongly suggest that expression of c-erbB-2 oncogene is another independent indicator of poor prognosis in breast carcinoma.

PURPOSE: This study was done to investigate the satisfaction with life in adolescents, and to identify factors affecting satisfaction with life for them. METHOD: The participants were 1,057 adolescents. Data was collected through self-report questionnaires which were constructed to include satisfaction with life, self-esteem, hostility and hopelessness. The data was analyzed using the SPSS program. RESULT: Satisfaction with life for adolescents was significantly different according to school type, grade, scholastic achievement, religion, monthly income of family, conversation with parents and conversation with friends. Satisfaction with life in adolescents correlated with self-esteem, hostility and hopelessness. Significant predictors influencing satisfaction with life in adolescents were self-esteem, hopelessness, school type, conversation with parents, monthly income of family and religion, and these predictors accounted for 37.8% of the variance in satisfaction with life. CONCLUSION: The above findings indicate that satisfaction with life in adolescents is influenced by self-esteem, hostility and hopelessness. Therefore when nursing interventions are developed to improve satisfaction with life in adolescents, these factors need to be considered.
