Recently there are increasing numbers of people participating in sports activities. Accordingly, the rate of sports injuries is increasing as well. In this light, this study was conducted to investigate the extent of acute damage and its forms by examining the current state of patients with sports injuries. This research study was conducted between January of 2008 and December of 2010 in Chosun University Hospital through retrospective review of the medical records of patients with sportsrelated injuries. The total number of patients with sports injuries who visited the emergency center was 887. The number of male patients was 726 (81.85%), far more than the number of female patients (18.15%). More than half of the patients, accounting for 419 (47.23%), had injuries on their face; second and common parts, in which injuries occurred, were upper and lower body, accounting for 146 (16.45%) and 193 (21.75%), respectively. The majority of patients did not undergo surgical treatment. Only 113 (12.73%) patients underwent surgical treatment. In addition, more than 80% of them were not hospitalized but 170 of them needed to be hospitalized. Most sports injuries occurred in young male patients. This can interrupt participation in sports activities for a long time and result in lower quality of life. Hence proper preventative measures and scientific treatment methods are needed.

Wild rice might have previously unidentified genes important for disease resistance and stress tolerance in response to biotic and abiotic stresses. A set of subtractive library was constructed both from leaves of wild rice plants, Oryza grandiglumis (CCDD, 2n=48), treated with fungal elicitor and from wounded leaves. A partial fragment that was homologous to PR10 genes from other plant species was identified via suppression subtractive hybridization and cDNA macroarray. The obtained full-length cDNA sequence (OgPR10) contains an open reading frame of 480 bp nucleotide, encoding 160 amino acids with a predicted molecular mass of 16.944 kDa and an isoelectric point (pI) of 4.91. The multiple alignment analyses showed the higher sequence homology of OgPR10 with PR10 genes identified in rice plants at amino acid level. The OgPR10 mRNA was not expressed by treatment with wounding, jasmonic acid, and salicylic acid, but markedly expressed in leaves treated with protein phosphatase inhibitors cantharidin and endothall, and yeast extract. In addition, the expression of OgPR10 mRNA was induced within 72 h after treatment with probenazole, one of well-known chemical elicitors, and reached the highest level at 144 h. Heterologous expression of OgPR10 caused growth inhibition and seedling lethality in E. coli and Arabidopsis, respectively. Chemically induced OgPR10 expression with glucocorticoid-mediated transcriptional induction system further reconfirmed its lethality on Arabidopsis seedling. In addition, OgPR10-expressing rice plants, Oryzae sativar were resistant against the infection of rice blast fungus, Magnaporthe grisea. These results indicate that OgPR10 is involved in probenazole- and microbe associated molecular patterns-mediated disease resistance responses in plants and is a potential gene for developing disease resistance crop plants.

A new soybean cultivar for soy-paste, “Mansu”, was developed from the cross between ‘Suwon 192’, which was tolerant to disease, late maturing and high yielding, and ‘Suwon 196’ which was early maturing and large seed by soybean breeding team in the Yeongnam Agricultural Research Institute (YARI) to make new variety having large seed and high yielding. A promising line, SS97213-2B-3SSD-39-1-1, was selected and designated as the name of ‘Suwon 236’. It was characterized by regional yield trials (RYT) for three years from 2004 to 2006 and released as the name of “Mansu”. It has a determinate growth habit, purple flower, grey pubescence, pale green seed coat, yellow cotyledon, large spherical seed (26.5 grams per 100 seeds). Maturity date is 4 days later than the check cultivar, Taekwang. The average yield of Mansu was 2.93 ton per hectare in the regional yield trials (RYT) carried out for three years from 2004 to 2006 which was 7 percent higher than that of the check cultivar, Taekwang.
