  • The present study was conducted to investigate the effect of whole wheat bread with added Lindera obtusiloba (LO) and Capsosiphon fulvescens (CF) ethanol extracts on serum glucose and lipid levels in Sprague Dawley rats. Rats were divided into five groups depending on the diet administered: normal bread (NC), whole wheat bread (W), whole wheat bread with LO leaves extract (WL), whole wheat bread with CF extract (WC), and whole wheat bread with freeze-drying CF (WDC). After 4 weeks of consuming the experimental diet, the blood glucose level and hemoglobin A1c contents were found to be significantly lower in the W, WL, WC, and WDC groups than in the NC group. The high-density lipoprotein-cholesterol levels increased in the WL group when compared to those in the NC group and triglycerides levels decreased in all wheat groups compared to those in the NC group. These results suggest that wheat breads containing LO and CF extracts are effective for preventing hypercholesterolemia and obesity.

  • Purpose: Dietary fiber is a component of carbohydrate that is linked closely with the carbohydrate quality, but few studies have investigated the association of high fiber intake with the cardiometabolic risk factors in Koreans. This study examined the association of high fiber and high carbohydrate intake with the cardiometabolic risk factors among Korean adults. Methods: This study included 15,095 adults aged ≥20 years, who participated in the 2013 ~ 2017 KNHANES. The dietary intake was obtained using a 24-h dietary recall method. The associations of high fiber and high carbohydrate intake with metabolic syndrome and dyslipidemia were examined by sex using multiple logistic regression analysis. Results: The median of dietary fiber was 23.6 g/day in men and 20.0 g/day in women. Dietary fiber intake increased gradually as dietary carbohydrate groups increased except for ≥80% of energy from the carbohydrate group. Women in the highest quintile of fiber intake showed a 33% lower risk of metabolic syndrome compared with those in the third quintile. When stratified into low fiber (LF) and high fiber (HF) groups using Adequate Intake of fiber for Koreans, men in the third quartile of carbohydrate intake showed a 44% and 51% higher risk of metabolic syndrome and atherogenic dyslipidemia than in the first quartile, respectively, but only in the LF group. Women in the second quartile of carbohydrate intake showed an 83% higher risk of hypercholesterolemia than in the first quartile in the LF group. On the other hand, as no significant association was observed between the carbohydrate intake and metabolic diseases among the HF groups in both sexes. Conclusion: These findings suggest that a high fiber intake might be associated with a reduced risk of metabolic syndrome and high carbohydrate intake with a low dietary fiber intake might be associated with an increased risk of several metabolic abnormalities among Korean adults. Further prospective studies will be needed to confirm the effects of high fiber and high carbohydrate intake on the cardiometabolic risk factors among Koreans.

  • Statins, the inhibitors of 3-hydroxy 3-methylglutaryl coenzyme A (HMG-CoA) reductase, are widely used in treatments of hypercholesterolemia and newly known as anti-cancer effect of various cancer cells. Recently, several studies suggested that reactive oxygen species (ROS) play a critical role on cell death signaling. However, mechanism of ROS by rosuvastatin is currently unclear. This study aimed to explore the molecular mechanism of apoptosis by rosuvastatin in human prostate cancer PC-3 cells. Cell viability and apoptosis-related protein expression were measured by MTT assay and western blotting, respectively. In addition, the levels of apoptosis and ROS were analyzed. The results showed that rosuvastatin dramatically reduced cell viability in a dose- and time-dependent manner. We confirmed that rosuvastatin induced apoptosis through reduction of procaspase-3 and cleavage of poly (ADP-ribose) polymerase (PARP) in PC-3 cells. In addition, rosuvastatin stimulated ROS production in a dose-dependent manner and pre-treatment with N-acetylcysteine (NAC), a ROS scavenger, significantly recovered rosuvastatin-induced ROS and apoptosis. Thus, we concluded that rosuvastain induces apoptosis through generation of ROS in human prostate cancer PC-3 cells and provides a promising approach to improve the efficacy of cancer therapy.

  • Purpose : The purpose of this study was to investigate the prevalence of obese and underweight adolescents in Incheon area and to examine the relationship between serum cholesterol level and obesity, then to assess the nutritional condition of adolescents. Methods : With a questionnaire regarding their demographic characteristics, blood samples were obtained from apparently healthy students aged 12 to 24 years by venipuncture at April and May, 2000. We measured the obesity index using standard body weight and the body mass index(BMI) according to the criteria established by the Korean Pediatric Society in 1998. Obesity was defined as BMI more than 95 percentile, and underweight less than 15 percentile by age and sex. Results : A total of 1,456 students(M : F=685 : 771) aged 12 to 24 years were included in this study. The prevalence of obesity by standard body weight in adolescents in Incheon were 11.7% : mild obesity 6.5%, moderate 4.6%, and severe 0.5%. By BMI, the prevalence of obesity was 6.4% in males and 6.2% in females. In males, the prevalence of obesity in rural areas was 8.5%, lower than in urban areas(14.3%). The prevalence of underweight by obesity index was 34.1% in rural areas and 22.9% in urban areas. In females, the prevalence of obesity was 12.5% in rural areas and 19.6% in urban areas. There were no significant differences between the two regions(P=0.529). The prevalence of obesity increased with age till 16.3% of peak prevalence in 16 years of age, and then decreased. In males, the prevalence of obesity in academic and vocational school were 13.7% and 9.7%, respectively(P=0.116). In females of the academic and vocational school, the prevalence of obesity was 6.8% and 18.0%, respectively(P=0.001). In obese adolescents, serum total cholesterol was over 200 mg/dL in 6.2%. Conclusion : This study revealed that the prevalence of obesity in adolescents was about 12% and that the prevalence of underweight adolescents was considerably high. We think nutritional assessment and intervention are warranted for adolescent students.
