Purpose: Traffic accidents are increasing due to the development and increment of transportation. Previous studies on analysis of the correlation between environmental factors and traffic accidents have rarely been reported. The purpose of this study is to analyze the correlation between rainfall and traffic accidents including accident mechanism, incidence, and trauma severity of patients. Methods: A retrospective review was conducted in 851 trauma patients who visited the emergency department (ED) after a traffic accident from January 2013 to December 2013; 248 patients due to a traffic accident when it was raining, and 603 patients when it was not raining. Demographic data, clinical data, and meteorological data (rainfall, daily mean air temperature, daily mean wind speed) in Busan were investigated. Results: The incidence of traffic accidents was one-second and the injury severity score of patients was two points higher on rainy days. In addition, the length of hospital stay was three days longer (p=0.037), and the prognosis was poor in the rain group. Comparison of severe injury sustained over rain, injury time, and accident mechanism showed approximately a 3-fold odds increased rate of severe injury on rainy days (OR 2.55, 95% CI: 1.11-5.83, p=0.004) and a seven-fold odds increased rate of pedestrian traffic accidents (OR 7.26, 95% CI: 3.52-9.26, p<0.001) compared with car traffic accidents. In addition, a four-fold increased odds of night time (OR 3.79, 95% CI: 1.98-7.25, p<0.001) compared with day time accidents on rainy days. Conclusion: The incidence of traffic accidents and injury severity of patients increased on rainy days. Therefore, we suggest expansion of the scope of the emergency and trauma team activation for proper treatment on rainy days.

Background: The treatment of rheumatoid arthritis still depend on conserve therapy in major. Recent studies report that n-3 polyunsaturated fatty acids(PUFA) could modulate the incidence and progress of arthritis. The purpose of this study was to investigate the effects of n-3 PUFA on the development of collagen-induced arthritis in rats. Materials and Methods: Female Louvain rats were used for this experiment. Rats were randomly assigned into either normal(m=8) or collagen-immunized groups, and collagen immunized groups were divided into control(n=8, normal diet) and n-3 PUFA(n=8, 5% n-3 PUFA in diet) groups. One week after feeding n-3 PUFA to rats, they were immunized with type II collagen emulsified in incomplete Freund's adjuvant into tail and back. Development of arthritis was confirmed by x-ray and microscopic examination. Results: Incidence of arthritis at the 5th week after immunization was 38% in control and 0% in n-3 PUFA. Rats with arthritis showed edema in hind paws and inflammation in synovial membrane of the knee joint. Plasma glucose and insulin were not changed by both of immunization and diet. Plasma triglycerides and cholesterol concentrations were decreased by n-3 PUFA. Conclusion: n-3 PUFA may prevent or treat collagen-induced arthritis in rats. Further studies are needed for action mechanism of it.
