The purpose of this study was to investigate the effects of cucumber beverage intake on fluid-regulating hormones and CRP in amateur marathoners between the ages of 47~49. Among research subjects, 8 male middle-aged marathoners who have completed the full marathon course over 5 times and who have run for over 50 months were selected. In two marathon races, they received firstly water and secondly cucumber beverage: 10 ml before the race, 50 ml every 5 km, and 200 ml after the race, adding up to 10 drinks and 710 ml in total amount of beverage taken. For statistics, one-way ANOVA within the group was conducted through SPSS 12.0; for post-examination, Duncan was utilized; and for inter-group examination, an independent t-test was used. Before, right after, and after the marathon, the cucumber beverage intake group had a significantly decreased serum ADH concentration compared to the water intake group. Both the cucumber beverage and water intake groups had significantly increased serum rennin levels before, right after, and after the marathon. Both the cucumber beverage and water intake groups had significantly increased aldosterone before, right after, and after the marathon. CRP levels didn't show change. In conclusion, intake of cucumber beverage during a marathon race was found to help with fluid-regulating hormones. This research has attempted to continue to study the influence on hormones that control body fluids.

The purpose of this study was to compare the shaping ability of three Ni-Ti file systems used by dental students or the experts and consequently to aid in choosing a proper systems for educational courses of dental students and beginners. Fifty students and ten dentists who have clinical experience over two years prepared 180 simulated root canals in resin blocks with three Ni-Ti systems; $ProFile^{(R)}\;(PF),\;HeroShaper^{(R)}\;(HS),\;K3^{TM}\;(K3)$. After preparation, the Ni-Ti files were evaluated for distortion and canal preparation time was recorded. The images of pre- and post-instrumented canals were scanned and superimposed. Amounts of increased canal widths, deviation, and centering ratio were calculated at apical 1, 3 and 5 mm levels and statistical analysis was performed The results were as follows : 1. HS showed the shortest preparation time and instrumented canal width in K3 was significantly larger than other groups (P<0.05). 2. At 1 and 3mm levels, all groups had outward deviation. In student group, at the 1mm level, PF had the least deviation (P<0.05). 3. In the centering ratio, the PF had the best centering ability compared to the others at 5mm level. At 1 and 3mm levels, HS and PF had better abilities than K3. Student group had better ratio than the expert at 3mm level with PF (P<0.05). Based on the results, it is surmised that the $ProFile^{(R)}$ is the safest and most ideal instrument for students and beginners.
