BACKGROUND: The recently developed nucleic acid amplification methods may provide us with very sensitive, specific and rapid tests for the detection of M. tuberculosis. So the aim of this study was to compare the commercial Amplicor M. tuberculosis kit and our in-house polymerase chain reaction (PCR) with the conventional culture and direct AFB staining method. Materials and METHODS: Among the total of 2,340 clinical specimens, 1,314 sputum samples were tested for the presence of M. tuberculosis by Amplicor PCR and 1,026 sputum samples were tested by in-house PCR performing with resin matrix preparation and DNA extraction, synthesized primer pair, detection using agarose gel electrophoresis. RESULTS: One hundred-seventeen specimens were positive by Amplicor PCR, 105 were positive by in-house PCR, 185 were positive by culture. The sensitivity of the Amplicor PCR for all of the specimens and for smear-positive and smear-negative specimens was 92.9%, 97.9% and 88.2%, respectively after discrepant analysis. The sensitivity of the in-house PCR for all of the specimens and for smear-positive and smear-negative specimens was 80.0%, 93.6% and 65.5%, respectively after discrepant analysis. The specificity of the Amplicor PCR and in-house PCR for all of the specimens was 97.9% and 99.0%, respectively. CONCLUSIONS: Amplicor PCR was more sensitive than in-house PCR, but there was another problems such as high false positive rate and high cost. So PCR may certainly become very useful in microbiological laboratories if PCR method is selected according to the laboratory conditions.

We report a case of weak subgroup A in a patient diagnosed as myelodysplastic syndrome. The patient's red cells was typed as O and his serum had anti-B. Red blood cell antibody screening test was negative. Am was confirmed by adsorption-elution test and saliva study.

The purpose of this study is to estimate the nutrient intakes and food habits among preschool children in Kyungjoo city. The subjects were 210 preschool children, aged 4-6 years. Measurements of the weight, height, chest circumference, and head circumference of the children were conducted. And general home environment and factors related to eating habits for preschool children were collected using a questionnaire that included information about family income, parents' education and occupations. The average weight-length index (WLI) for the subjects was 103.9%. Using the WLI, 20.0% of the preschool children were underweight, 48.6% were normal, 19.0% were overweight, and 12.3% were obese. On the Rohrer index, 13.8% of the preschool children were underweight, 38.5% were normal, and 47.7% were over weight or obese. The average daily intake (% of RDA) of energy and each nutrient was 1323.5 kcal (81.3%), Ca 484.3 mg (80.7%), Fe 7.05 mg (88.1%), vitamin A 420.0 RE (105%), vitamin B1 0.76 mg (95.0%), vitamin B2 0.87 mg (87.0%), and vitamin C 53.1 mg (106.2%), respectively. In particular, older subjects had lower intake in RDA % of calcium and iron. The energy intake ratio from snacks was much higher than the recommended level of the preschool children. With regard to frequency of regularity of breakfast, 1.9% of preschool children skipped every morning and 7.6% of the children skipped more than 5 per week. With regard to the intake frequency of vegetables, fruits, complex carbohydrates, and milk, 13.3%, 19.9%, 22.8%, and 41.8% of the children ate more than 5 times per week. The eating habit score was positively correlated (r = 0.18, p < 0.05) with household income. This study suggests that nutrition education to increase fruit and vegetable consumption for preschool children should be emphasized. Also a nutrition education program is needed to enhance consuming calcium and iron intake for adequate growth.
