Osteoporosis is a medical condition of global concern, with increasing incidence in both sexes. Bone mineral density (BMD), a highly heritable trait, has been proven a useful diagnostic factor in predicting fracture. Because medical information is lacking about male osteoporotic genetics, we conducted a genome-wide association study of BMD in Korean men. With 1,176 participants, we analyzed 4,414,664 single nucleotide polymorphisms (SNPs) after genomic imputation, and identified five SNPs and three loci correlated with bone density and strength. Multivariate linear regression models were applied to adjust for age and body mass index interference. Rs17124500 (p = 6.42 × 10−7), rs34594869 (p = 6.53 × 10−7) and rs17124504 (p = 6.53 × 10−7) in 14q31.3 and rs140155614 (p = 8.64 × 10−7) in 15q25.1 were significantly associated with lumbar spine BMD (LS-BMD), while rs111822233 (p = 6.35 × 10−7) was linked with the femur total BMD (FT-BMD). Additionally, we analyzed the relationship between BMD and five genes previously identified in Korean men. Rs61382873 (p = 0.0009) in LRP5, rs9567003 (p = 0.0033) in TNFSF11 and rs9935828 (p = 0.0248) in FOXL1 were observed for LS-BMD. Furthermore, rs33997547 (p = 0.0057) in ZBTB and rs1664496 (p = 0.0012) in MEF2C were found to influence FT-BMD and rs61769193 (p = 0.0114) in ZBTB to influence femur neck BMD. We identified five SNPs and three genomic regions, associated with BMD. The significance of our results lies in the discovery of new loci, while also affirming a previously significant locus, as potential osteoporotic factors in the Korean male population.

The pathogenic and non-pathogenic microorganism have been isolated from the indoor airborne, the closest environment of human beings. Our purpose were to investigate the distribution of fungi and bacteria in indoor airborne sampled from 7 locations in Namseoul University for 2 months from September to October, 2010. The isolated bacteria were identified by Gram stain and biochemical test using VITEKTM system, also The fungus were identified by LPCB. The experiment on microorganism concentration of indoor air carried out and the average of total microorganism was measured. When airborne bacteria were isolated and identified. The isolation rates of Gram positive cocci, Gram positive bacilli, Gram negative bacilli, and Gram negative cocci were 38.3%, 22.4%, 2.7%, 0%, respectively. In Gram positive cocci, the most strains were identified as Micrococcus spp. In Gram positive bacilli, the most strains were identified as Bacillus spp. The frequently isolated fungi were Aspergillus sp, Penicillium sp, Alternaria sp, Rhizopus sp, Mucor sp. respectively. Further systematic studies are necessary with an emphasis on species identification. Key Words : Microorganism, Fungus, Indoor Airborne, Micrococcus, Aspergillus

The distributed species and number of viable microorganisms in drinking water were monitored according to water dispenser maintenance. our purpose was to investigate the distribution of bacteria in drinking water dispenser. To analyze possible dispenser contaminations sampling were performed from 14 locations in Namseoul University for 3 months from March to May, 2010. The isolated bacteria were identified by Gram stain and biochemical test using VITEKⅡ systems. The microorganism concentrations around the water discharge areas were measured and the average of total microorganisms was determined. The number of bacteria were measured by McFarland turbidity. The water and water discharge areas were separated and identified. The isolation rates of Gram positive cocci and Gram negative bacilli were 56.5%, 17.4% respectively. The frequently isolated bacteria were Staphylococcus epidermidis, Enterobacter aerogenes, Enterbacter sakazakii, Alcaligenes faecalis, Acinetobacter baumannii, Staphylococcus hominis, respectively. Further systematic studies are necessary with an emphasis on species identification. Key Words : Microorganisms, Water Discharge Areas, Drinking Water, McFarland
