This study aimed to determine how aquarobic exercise affects obese women on body fat percentage as measured by body composition and blood pressure and vascular aging as measured by vascular function. The purpose is to provide exercise therapy guidelines for the development of body composition and vascular function in obese women. The subjects of the study were 24 obese women, divided into 12 AEG (Aqua Exercise Group) and 12 NEG (Non-Exercise Group), and compared and analyzed body fat, blood pressure, and vascular aging between groups and before and after. The exercise period was 3 times a week for 8 weeks, the exercise time was 50 minutes, and the intensity was 50 to 75% of HRmax. Results There was a significant decrease in body fat percentage after than before only in AEG (p<.001), and a significant effect was observed in Time (p<.001) and Time*Group (p<.001). Systolic Blood Pressure showed a significant decrease after than before only in AEG (p<.001), and a significant effect was observed in Time (p<.01) and Time*Group (p<.001). Diastolic Blood Pressure showed a significant decrease after than before only in AEG (p<.01), and a significant effect was observed in Time (p<.05) and Time*Group (p<.01). Vascular aging showed a significant decrease after than before only in AEG (p<.01), and a significant effect was observed in Time (p<.01) and Time*Group (p<.001). Therefore, aquarobics is an effective exercise in reducing body fat percentage, blood pressure, and vascular aging in obese women, and it is believed that it can be used as exercise therapy guideline data for the development of body composition and vascular function in obese women.

The purpose of this study is to investigate the effect of the jumping diet program, which is popular in GX exercise, on lifestyle - related factors and blood stress in obese middle - aged women. Subjects underwent a 40-minute-a-day exercise three times a week for eight weeks and to determine the difference between before and after exercise, a t-test of the corresponding sample was conducted and the following conclusions were drawn. The results of decreasing body weight and body fat percentage after exercise were found to be statistically significant. In addition, it was decreased in TC, LDL-C and TG, which are lifestyle-related factors, and HDL-C was increased, resulting in statistically significant results, and the fasting blood glucose level was maintained to be normal. And blood stress did not enter the normal range, but decreased, indicating a significant difference. Taken together, the jumping diet exercise program improves body composition items and lifestyle-related factors in obese middle-aged women and reduces blood stress. Although the duration of jumping exercise was relatively short, it was thought that improvement of body shape and lifestyle - related factors were obtained for middle - aged obese women through 30 minutes of high intensity exercise and muscle power supplementation exercise. If I continue this exercise for a long time, I think it is one of the exercise programs that can relieve middle age obesity and maintain health.

The purpose of this study was to investigate effects of walking exercise on body composition, insulin resistance, circulating concentration of diponectin, ghrelin and resistin in obese male university students. Subjects were divided into control group (n = 14) and walking exercise group (n = 13). Walking exercise was performed 4 times a week at the intensity of 65-75% HRmax (1-4 weeks: 65% HRmax, 5-8 weeks: 70% HRmax, 8-12 weeks:75% HRmax). And the change of body composition, blood glucose, insulin, HOMA-IR, adiponectin, ghrelin and resistin has been measured before and after 12 weeks of exercise. Statistical technique for data analysis was two-way ANOVA to determine the difference between before and after 12 weeks of walking exercise. As a result, body weight, BMI, and VO_2max were significantly improved during post-exercise. The change of adiponectin, ghrelin and resistin in experimental group was significantly changed after 12-week walking exercise. The present study provides the possibility that walking exercise may be a critical mediator to improve insulin resistance, concentrations of adiponectin, ghrelin and resistin in obese male university students.

The purpose of this study was to investigate the effect of walking program on plasma hs-CRP, interlukin-6 and TNF-α in obese middle-aged women. The subjects for this study were composed of twenty-three obese middle-aged women. The subjects were classified to two groups; control group(CG, n=13), walking exercise group(WEG, n=15). The WEG exercised for 12 weeks and were monitored for changes in BMI(body mass index), C-reactive protein(CRP), interlukin-6(IL-6), and tumor necrosis factor-alpha(TNF-α). The results of this study are as follow; BMI was significantly decreased in WEG after 12 weeks of walking exercise. CRP, IL-6, and TNF-α were significantly decreased in WEG after 12 weeks of walking exercise. CRP, IL-6, and TNF-α showed a significant correlation with BMI. In conclusion, the results of this study suggest that walking exercise can contribute to the better benefit in BMI, CRP, IL-6, and TNF-α for obese treatment.

목적: 국내에서 Helicobacter pylori를 제균하기 위해 사용되는 PPI 표준 삼제요법과 bismuth 포함 사제 요법은 적지 않은 제균 실패율은 보이고 있다. 이번 연구의 목적은 일차제균 치료에 실패한 환자에서 이차 치료로 bismuth 포함 사제요법과 삼차 치료로 rifabutin 포함 삼제요법의 H. pylori 제균율을 분석하고, 구제요법으로서의 역할에 대해 알아보고자 하였다. 방법: 2004년 7월부터 2006년 10월까지 중앙대학교 필동병원과 용산 병원을 내원하여 상부위장관 내시경 검사에서 H. pylori 감염 진단을 받고 PPI 삼제요법 치료에 실패한 52명의 환자를 대상으로 이차 bismuth 삼제요법을 시행하였다. 또한 이차 제균에 실패한 3명의 환자를 대상으로 rifabutin 포함 삼제요법으로 삼차 구제요법을 시행하였다. 또한 연령, 성별, 질환, 음주, 흡연, 그리고 NSAIDs 복용력에 따른 제균율을 분석하였다. 결과: Bismuth 포함 사제요법의 제균율은 84.6%였으며, rifabutin 포함 삼제요법의 제균율은 100%였다. 연령, 성별. 질환, 음주, 흡연, 그리고 NSAIDs 복용력에 따른 의미있는 통계학적 유의성은 보이지 않았다. 결론: Bismuth 포함 사제요법은 PPI 포함 일차 삼제요법 실패 후 이차 치료로 여전히 효과적이며, rifabutin 포함 삼제요법도 국내에서 이차 치료 실패 시 삼차 구제요법으로 사용되어질 수 있을 것으로 생각한다. Background/Aims: Proton pump inhibitor (PPI)-based standard triple therapy for Helicobacter pylori infection is widely used, but it has a considerable failure rate. The aim of this study was to evaluate the efficacy and tolerability of rescue therapies with a quadruple regimen and a rifabutin-based regimen for patients who experienced failure with PPI-based standard triple therapy. Methods: From July 2004 through October 2006, 52 patients for whom first-line triple therapy (PPI, amoxicillin and clarithromycin) had failed were included in this study. They were treated with a quadruple regimen for 7 days (PPI, bismuth, tetracycline and metronidazole) as a second-line therapy. For third?line therapy, a rifabutin-based regimen (PPI, rifabutin and amoxicillin) was prescribed for 14 days. The H. pylori status was determined before and at least 4 weeks after therapy by the 13C urea breath test or by endoscopy with antral and corpus biopsies for a rapid urease test, histological examination and culture. Results: The mean age was 52.6 years. Thirteen patients (25%) of the 52 patients were dropped. The eradication rate of the quadruple therapy was 84.6% (33/39). Three patients of the 6 failures with quadruple therapy were then treated with the rifabutin-based regimen. The eradication rate of the rifabutin-based therapy was 100% (3/3). Adverse effects (10.2%) were reported in 4 patients who were treated with quadruple regimen. Conclusions: The quadruple regimen is still an effective second-line therapy for Korean patients who experience failure with PPI-based standard triple therapy. The rifabutin-based regimen could be used as a third-line rescue therapy in Korea. (Korean J Med 74:23-29, 2008)

This study was designed to investigate the effects of long-term training on the lipid(triglyceride, cholesterol) and lipoprotein(HDL-cholesterol). The subjects consisted of 9 junior female athletes(exercise career, three month ; A group) and 6 athletes(exercise career fifteen month ; B group) and 12 junior school girls as control group(C group) who all were about thirteen years old. Both athlete groups(A,B group) were continuous to participate in six month training and their blood samples were collected at pre mid(after three month) and post (after six month). The control subjects donated their blood at pre and post(after six month). The collected blood were analyzed for the triglyceride, cholesterol, High density lipoprotein cholesterol and HDL-C/TC ratio. The result through the statistical analysis of this data were summarized as follows 1. The pre-levels of triglyceride and total cholesterol in Athlete group, especially B group were lower than those in Non-athlete group(p<0.01). HDL-C level and HDL-C/TC ratio were highest in B group among three group(p<0.05). 2. HDL -C level and HDL-C/TC ratio in both athlete group, especially A group were significantly decreased after three and six month(p<0.01) while in control group all item were not changed. The result indicated that Triglyceride cholesterol in pre-adolescent girl can be significantly changed by three month training and the change of HDL-C need more long term training(more than three month).
