The extracts of hoelen was evaluated for protective effects against the adverse effects of a high fat diet. Mice were divided into four groups; normal diet (control), high fat (HF) diet, high fat+water extract (HF+WE) and high fat+ethanol extract (HF+EE) and fed for 4 weeks. Food calorie consumptions were not significantly different between groups. Weight gain was significantly lower in HF+EE than the high fat group. Also, liver weight was significantly lower in HF+EE than the control group. The weight of epididymal fat tissue was 1.4 fold higher in high fat groups than control group. The concentration of serum triglyceride, total cholesterol and LDL-cholesterol increased in high fat group, but decreased by hoelen ethanol extract administration. Also serum HDL-cholesterol was decreased in the high fat group, but increased by the hoelen ethanol extract administration. Liver triglyceride and total cholesterol were not significantly different among groups. These data suggest that hoelen ethanol extract administration improves the serum lipid profiles of mice.

Purpose: In order to clarify the carcinogenesis mechanism from chronic atrophic gastritis toward gastric cancer, we measured the pepsinogen I and II and compared their ratio with several clinical findings. Materials and Methods: We measured the preoperative serum pepsinogen I and II by using a radio-immunoassay and compared their ratio with several clinical findings, such as tumor size, mucinous vs non-mucinous tumor, cell differentiation, tumor location, depth of invasion, lymph-node status, Lauren's classification, and peritumoral atrophy in 103 consecutive patients with gastric adenocarcinomas who had received resections at Bundang CHA Hospital during the period from July 2003 to February 2005. Results: There were significant differences in the serum pepsinogen I/II ratio between patients with mucinous vs non-mucinous tumors (n=4 vs 9 and mean pep I/II=1.29 vs. 2.99, p=0.0288), with tumor size more than and less than $10cm^2$ (n=55 vs. 48 and mean pep I/II=2.64 vs. 3.24, p=0.0491), and with or without peritumoral atrophy (n=94 vs. 9 and mean pep I/II=2.83 vs. 3.89, p=0.0466). In patients with peritomoral atrophy, the pepsinogen I/II ratio was also lower in larger tumors (n=48 vs. 46 and mean pep I/II=2.44 vs. 3.23, p=0.0083). Well-differentiated carcinomas showed significantly lower serum pep I/II ratios than signet-ring-ceil types. There was no correlation between serum pep I/II ratio and tumor location, depth of invasion, lymph-node status, or Lauren's classification Conclusion: We proved the existence of a correlation between serum pepsinogen level and musosal atrophy, but these results are not sufficient for clinical application of serum pepsinogen level as a screening tool for gastric cancer.

The purpose of this study was to investigate the effects of sports massage in the recovery period after maximal exercise on heart rate(HR), oxygen uptake(OU), and blood lactate(BL) of ssireum players. The participants of this study were consisted of 24 ssireum players in university team(UT) and business team(BT). The first experiment had a rest recovery period for 20 minutes after the maximal exercise, and the second experiment gave a sports massage was performed the order of abdominal, waist and lower legs in a prone position for 20 minutes. The interaction effects of massage treatment and recovery period in HR showed a higher recovery ability in both the UT and BT when the massage treatment was given 10 minutes after recovery than when it was not given. The main effects of recovery period showed in all variables of HR, OU, and BL. The main effects of BL on massage treatment was significant low in both the UT and BT when the massage was given. And, the main effects of OU was significantly lower only in the BT. In conclusion, compared sports massage treatment on ssireum players after maximal exercise positively affected the recovery mechanism of HR, OU, and BL than the rest recovery method.

The purpose of this study was to investigate the effect of Saengmaeg-san intake on blood lipids and arteriosclerosis index in male tennis players. Seventeen male tennis players enrolled in university were assigned to a Saengmaeg-san intake group (n=9) and a placebo control group (n=8) according to whether they took Saengmaeg-san during 4-week high-intensity tennis training. Tennis training was conducted 5 times a week for 4 weeks, and the exercise intensity was performed at 70-90% of the spare heart rate. The intake of Saengmaeg-san was 110ml at a time before breakfast, before, during, during, and after exercise, and after dinner, a total of 7 times, 770ml per day. For all data, mean and standard deviation were used. Two-way repeated measures ANOVA was used to examine the effect of time and treatment, and Pearson's Correlation was used to examine the relevance of differences in blood lipid responses after treatment. As a result of this study, the Saengmaeg-san intake group significantly improved blood lipids (triglyceride, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol) and arteriosclerosis index, and there was a significant correlation appeared between ∆TG, ∆LDL-C, and ∆TC. As a result, the intake of Saengmaeg-san during high-intensity training of male college student tennis players can have a positive effect on blood lipids and arteriosclerosis index, suggesting that it can be an effective sports drink as an exercise supplement.

This study tried to suggest the applicapability of soy protein supplementation and treadmill running exercise for the replacement theraphy on negative effects to estrogen metabolism in menopause. This study was analyzed the effects of 8 week soy protein supplementation and treadmill running exercise on the changes of body composition, blood concentrations of glucose, insulin, triglycerides, C-reactive protein (CRP) and estradiol, estrogen receptor gene expression of liver in ovariectomized rats. Ovariectomized groups showed the increasing responses of body weight, body fat percentage, and blood concentration of triglycerides, but these groups showed the decreasing responses of blood estradiol level and estrogen receptor gene expression in liver. Ovariectomized groups showed the positive responses of blood concentrations of lipid markers, insulin, estradiol, and estrogen receptor gene expression of liver except bone mineral contents after 8 week soy protein supplementation and treadmill running exercise. I could find the positive effects of 8 week soy protein supplementation and treadmill running exercise on the estrogen and lipid metabolism in ovariectomized rats, but this study could not confirmed the detailed replacement program of exercise intensity, duration, and soy protein volume for estrogen metabolism in ovariectomized rats.

흡연은 각종 암의 발병율을 높이고 동맥경화증, 혈전증과 같은 관상심장질환의 주요 발병요인이 되는 것으로 알려져 있다. 흡연자에게 보여지는 지질과산화작용에 의한 LDL의 산화는 구리나 철과 같은 항산과 관련 무기질에 의해 촉진되며, 특히 구리는 매우 연관성이 높은 물질로 보고되었다. 따라서 흡연자의 혈중 무기질 함량의 측정은 항산화 능력과 심혈관계 질병의 진단 및 예후 판정에 민감한 지표로 사용할 수 있을 것으로 사료된다. (중략)
