The purpose of this study was to examine the sport commitment behavior of participants in Leisure sport and Exercise, to investigate the relationship between participant`s personality and his sport commitment behavior, and to analyze the relationship between passional sport participants and personality factors. In order to do this, first, we classified the total subjects into groups according to sport commitment, and analyzed the difference in personality factors according to the degree of sport commitment. In doing this, we used the `Questionnaire of Sport Commitment` developed by Jung(1997), and used the ` Questionnaire of Personality` officially approved by Korea Guidance, which was first developed in the name of NEO-PI-R by Costa and McCrae (1992c), was translated into Korean and examined by Lee(1995), and was reexamined again by An and Lee(1996). The subjects totalled 442 persons(321-mail, 121-femail) who participating in leisure sport and exercise sport (swimming, baseball, tennis, paragliding, health). The age of subjects ranged from 18 to 49. We used the t-test in analysis of the differences of personality factors according to degree of sport commitment (high commitment, low commitment). We used the correlation in analysis of the relationship of Big-5 factors and sport commitment factors. The results of statistical analysis are as follows : First, the participants in the high sport commitment is higher than one in the low sport commitment in extraversion, openness of experience, agreeableness, conscientiousness and impulsiveness of neuroticism, while the participant in the low sport commitment is higher than one in the high sport commitment in neuroticism factors. To the conclusion, the active sport-participants in more stable in personality, is more extroversive, open to experience, agreeable and conscientiousness than passive sport-participant. Therefore the personality make influences the degree of participation in leisure sport and exercise.

The inhibitory effects of diol, triol and total saponins isolated from red ginseng on the lipoperoxide formation in vitro and in vivo were studied and correlated with anti-aging. To this end, antioxidant activity, induction period and lipoperoxide were measured by the methods of electron donating ability(EDA), peroxide value(POV) and thiobarbituric acid (TBA) value. Also superoxide dismutase (SOD) and peroxidase activities were measured by the pyrogallol autoxidation method (ΔA 420 ㎚/min) and initial velocity(ΔA 436 ㎚/ min), respectively. Diol and triol saponins were fractionated by Kiesel gel column chromatography (CHCl₃ MeOH-H₂O, 65:35:10, lower phase) and identified using authentic ginsenosides. The compositions of diol and triol saponins were analyzed by high performance liquid chromatography(HPLC). The comparative experiments of EDA, TBA value and induction period in vitro were carried out, and it was proved that triol saponin was more effective than diol saponin. This may be explained by the structural feature that triol saponin in contrast with diol saponin does not have glycoside linkage at the C₃ OH residue of 20(S)protopanaxatriol, and the hydroxyl group of C₃-position in triol saponin seems to be closely related to the antioxidative action. From the comparative study of diol and triol saponins on intraperitoneal (i.p.) and/or oral (p.o.) administrations, it was found that triol saponin was more effective than diol saponin in the inhibitory effects on the lipoperoxide formation of liver, kidney and blood. From the comparative experiments of superoxide dismutase(SOD) activity for both the i.p. and p.o. administrations, it was similarly indicated that the triol saponin group showed remarkable inhibitory effects in comparison with the diol saponin group. This may be due to the scavenger of superoxide radical (O₂^-·) by SOD in liver. In particular, the orally administered group showed more stronger inhibitory effects on the lipid peroxidation in comparison with the intraperitoneally administered group, suggesting that the continuous oral administration was more effective than the temporary administration. The peroxidase activity also showed a similar trend to the SOD activity in vitro and in vivo experiments.

POV에 의한 유효기간(誘導期間)은 이들 가수분해물(加水分解物) 홍삼(紅蔘)사포닌보다 훨씬 높았으며 prosaposenin>panaxatriol>panaxadiol의 순이었다. in vivo에서 복강(復腔)(i. p.) 및 경구(經口)(p.o.) 투여(投與)에 의한 생체내(生體內) 과산화지질생성(過酸化脂質生成) 억제효과(抑制效果)는 대조군(對照群)에 비(比)해 훨씬 효과적(效果的)이었으며, 홍삼(紅蔘)사포닌과 비교(比較)했을 때 간장(肝臟)과 신장(腎臟)에는 거의 비슷한 효과(效果)를 나타냈지만 혈액(血液)에서는 이들 가수분해물(加水分解物)이 홍삼(紅蔘)사포닌보다 훨씬 효과적(效果的)이었다. 효소활성(酵素活性)으로서 superoxide dismutase 활성(活性)을 in vitro에서 비교해 보면 이들 가수분해물(加水分解物)이 $24.2{\sim}36.4%$의 과산화지질생성(過酸化脂質生成) 억제효과(抑制效果)를 나타내고 있어, 홍삼(紅蔘)사포닌의 12.1%보다 $2{\sim}3$ 배(倍)의 효과(效果)를 나타내고 있었고, in vivo에서는 복강(復腔)(i. p.) 투여(投與)에서는 $12.9{\sim}22.2%$. 경구(經口)(p.o.) 투여(投與)에서는 $11.2{\sim}21.6%$의 높은 활성(活性)을 나타내고 있었다. 단 peroxidase 활성(活性)은 복강(復腔)(i. p.) 투여(投與)에서는 $129.0{\sim}188.6%$, 경구(經口)(p. o.) 투여(投與)에서는 $111.4{\sim}139.6%$의 활성(活性)을 나타내고 있었다. The inhibitory effects of red-ginseng saponin hydrolyzates (prosapogenin, panaxadiol and panaxatriol) on lipoperoxide formation in vitro and in vivo were investigated and correlated with anti-aging. Saponin hydrolyzates showed the electron-donating ability (EDA) of 12.88 - 19.76% to DPPH in vitro, and the ability was distinctively decreased in order of prosapogenin, panaxatriol and panaxadiol. The induction period of saponin hydrolyzates, which was measured by the method of peroxide value (POV), was much longer than red-ginseng saponin and decreased in order of prosapogenin, panaxatriol and panaxadiol. The inhibitory effect of saponin, hydrolyzates in vivo was remarkably greater than control. In contrast to red-ginseng saponin, almost similar inhibitory effect in rat liver and kidney was observed, whereas they were much more effective than red-ginseng saponin in blood. The superoxide dismutase (SOD) activity of saponin hydrolyzates in vitro was also measured, and the inhibitory effect of saponin hydrolyzates was found to be 24.2-36.4% and 2-3 times greater than that of red-ginseng saponin (12.1%). Saponin hydrolyzates showed the inhibitory effects of 11.2-21.6% and 12.9-22.2% in oral and intraperitioneal administrations, respectively. It was also found from the measurement of peroxidase activity that the inhibitory effects of saponin hydrolyzates were 111.4-139.6% in oral administration and 129.0-188.6% in intraperitoneal administration.

紅蔘과 白蔘의 抗酸化作用에 의한 老化抑制作用을 究明하기 위하여 80% ethanol extract 및 水飽和부탄올로 移行한 saponin을 試料로 하여 in vitro 및 in vivo 實驗을 통하여 紅蔘과 白蔘의 老化抑制作用을 比較하였다.<br/> DPPH에 대한 電子供與能(EDA), TBA value 및 peroxide value에 의한 過酸化脂質生成抑制作用, superoxide dismutase 및 peroxidase의 活性測定등으로 紅蔘과 白蔘의 老化抑制作用을 比較환 結果, 紅蔘은 長期間에 걸친 連續投與에서 白蔘보다 過酸化脂質生成抑制作用. superoxide dismutase 및 peroxidase의 活性을 有意性있게 增加하였다. 生體內 實驗에서 紅蔘이 白蔘보다 老化抑制作用이 현저한 것은 蒸蔘 및 加工處理中 saponin pattern의 變化에 起因하며 白蔘의 PT/PD ratio가 0.401인데 反해 紅蔘의 PT/PD ratio가 0.561로서 triol saponin이 增加되었기 때문이다. The inhibitory effects of the extract and crude saponin of red and white ginsengs on lipoperoxide formation in vitro and in vivo were studied and correlated with anti-aging. To this end, antioxidant activity, induction period and lipoperoxide were measured by the methods of EDA, POV and TBA value. And also superoxide dismutase and peroxidase activity were measured by pyrogallol autoxidation method (ΔA 420/min) and initial velocity(ΔA 436/min), respectively.<br/> From HPLC analysis, the PT/PD ratio of red and white ginsengs was found to be 0.561% and 0.401%, respectively, and red ginseng increased the PT/PD ratio in comparison with white ginseng. The EDA activity of red ginseng was higher than that of white ginseng; red ginseng showed stronger antioxidative effect than white ginseng.<br/> The inhibitory effect of red ginseng was lower than that of white ginseng during the induction period. It was proved that high molecular coloring substance was deeply related to the initial stage of lipoperoxidation.<br/> There was no significant difference between red and white ginsengs in both in vitro and intraperitoneal administration experiments, and red ginseng was more effective than white ginseng in long-term administration. And also inhibitory effect on lipoperoxide formation was mainly occurred in liver, suggesting that the function of liver played an important role in anti-aging actions.<br/> From the measurement of superoxide dismutase(SOD) activity for both ginseng groups intraperitoneally and orally administered, it was found that red ginseng group administered extract and crude saponin showed remarkable inhibitory effects in comparison with white ginseng. In particular, orally administered group showed more stronger inhibitory effect on lipid peroxidation in comparison with intraperitoneally administered group. It was also found that. the continuous oral administration was more effective than temporary administration.<br/> Red ginseng was more notable anti-aging effect in comparison with white ginseng in vivo, and this may be due to the increase of SOD activity in rat-liver. Peroxidase activity also showed similar trend to SOD activity in vitro and in vivo experiments.<br/> Red ginseng was not only superior to white ginseng for preservation but also for biochemical and pharmaceutical efficacy.
