This study was attempted to evaluate the effectiveness of extract of fermented red pepper The extract of fermented red pepper was prepared from fermented red pepper puree and polydextrose. Sixteen female college students were participated in this 8 weeks weight control program. All subjects were randomly assigned to the Internet Diet (ID) group or Internet I, fermented red pepper (IR) group. Mean energy intake of ID group was 1,279.9$\pm$112.0 kcal (carbohydrate: 66.9%, protein: 17.4%, fat: 15.6%) and IR group consumed 1,223.8$\pm$57.1 kcal (carbohydrate: 66.3%, protein: 19.3%, fat: 14.4%) during program. The ID group lost 2.5$\pm$1.0 kg of body weight, 0,9$\pm$0,7 kg of fat mass and 1.6$\pm$0.7 kg of lean body mass, and the IR group lost 2.7$\pm$0.3 kg of body weight, 1.8$\pm$0.6 kg of fat mass and 0.9$\pm$0.7 kg of lean body mass. There was no significant differences in the loss of total body weight & lean body mass between two groups, however, the fat mass and the abdominal fat were significantly decreased in the IR group compared to the IC group (p<0.05) The ID group experienced a significantly reduced Resting Metabolic Rate (RMR), however, IC group slightly increased. The change of RMR between groups were significantly different (p<0.05) . There were no differences in the change of blood glucose, total-cholesterol, HDL-cholesterol, LDL-cholesterol and triglyceride between groups. Therefore, the intake of fermented red pepper doting the weight control program might decreased the body fat especially abdominal fat and prevent the decline of RMR during weight reduction period.

This study was done to evaluate the effectiveness of dietary calcium level(a diet which met 100% or twice the calcium level in AIN-76 diet) on preventing bone loss in ovariectomized rats. Forty female Sprauge-Dawley rats(body weight 200$\pm$5g) were divided into two groups. One group were ovariectomized(Ovx) while the others received sham operation(Sham). Thereafter, each rat group was further divided into normal calcium diet(NCD, 0.52%) and high calcium diet(HCD, 1.04%) sub-groups. All rats were fed on experimental diet and deionized water ad libitum for 8 weeks. Urinary pyridinoline & creatinine and serum estradiol, luteinizing hormone, calcium, phosphate, total protein, albumin, alkaline phosphatase and osteocalcin were determined. There were no significant differences in serum calcium. total protein and albumin in the two groups(Ovx vs Sham) of rats. Ovariectomized rats had significantly lower estradiol than sham operated rats. There was a highly significant correlation between total bone mineral density(TBMD) and overall level of esteradiol(r=0.59, p<0.05). Total bone mineral density did not correlate significantly with ALP or osteocalcin, although a negative trend was evident. However, the rats fed high calcium diet had a lower crosslinks value and osteocalcine than the rats fed normal calcium diet. An increased rate of bone turnover is usually associated with a decrease in bone mass bexause bone formation at each remodeling site is never as great as resorption. Ovariectomized rats fed high calcium diet had a lower crosslink value and osteocalcin; it means high cacium diet decreased bone turnover rate. The findings from the present study demonstrated that bone loss due to ovarian hormonal deficiency can be partially prevented by a high calcium diet. Futhermore, these findings support the strategy of the use of a high calcium diet in the prevention of estrogen depletion bone loss (postmenopausal osteoporosis).

Purpose: This study compared the effects of a high glycemic load (high GL) diet and low glycemic load (low GL) diet on the body weight, body fat, blood pressure, and blood lipid indicators. Methods: Twenty-one young adults aged between 21 and 28 years who were overweighted or obese (body mass index [BMI] between 23 and 33.5 kg/㎡) before the study and after calorie reduction diets with either low GL or high GL for 2 weeks each were examined. The study was a randomized crossover design with a 2-week washout period between the 2 types of diet. The order of the low GL and high GL diet periods was randomized. The body weight, body fat, blood pressure, levels of blood lipids, fasting glucose, insulin, homeostatic model assessment (HOMA) insulin, C-peptide, and HOMA C-peptide were measured at the baseline, as well as 2, 4, and 6 weeks after starting the experiment. Results: When subjects were on the low GL diet, they lost more weight than those eating the high GL diet (mean ± SD, -2.77 ± 1.09 vs. -1.56 ± 0.78 kg; p < 0.001); there were greater decreases in body fat mass (-1.62 ± 1.19 vs. -0.88 ± 0.91 kg; p = 0.024) and BMI (-0.95 ± 0.32 vs. -0.56 ± 1.08 kg/㎡; p < 0.001). On the other hand, there were no significant differences in changes in biochemical parameters, such as blood lipids and fasting glucose levels, and blood pressure. The body weight, body fat mass, BMI, percent body fat, blood pressure, cholesterol (total, low-density lipoprotein, and high-density lipoprotein), fasting glucose, C-peptide, HOMA-insulin resistance-C-peptide levels were decreased significantly at 6 weeks. Conclusion: The low GL diet may be more effective in losing body weight, body fat mass, and BMI than the high GL diet for 2 weeks in healthy young overweight or obese adults.

The study was performed to investigate the effects of whey protein-rich meal substitute added with vitamins, minerals, and lactobacillus powder probiotics on weight loss, body fat, and body composition in 24 female volunteers for 4 weeks. Whey protein-rich meal substitute was consumed with low-fat, high calcium milk (1% fat, 260 mg/200 mL) twice a day. Subjects submitted 3-day diet records and a life-style questionnaire before the study. During the study, subjects were required to turn in a diet record every day and consume the meal substitute formula in the metabolic ward at C university for 4 weeks. Anthropometric measurements were carried out weekly by Inbody 7.0. The dietary intake and anthropometric data were analyzed to compare changes before and after the study by paired t-test with SPSS version 23.0. The subjects were mostly early 20's and either overweight or obese and highly motivated to lose weight. Most of the subjects consumed three meals per day regularly and spent mostly 10~15 minutes for a meal. Their caloric intake was relatively low and decreased from 1,360 kcal at week 0 to 1,100 kcal after 4 weeks. However, total protein intake increased while carbohydrate and fat intakes decreased (p<0.05) after the trial. Nine vitamin intakes after the study improved compared to those before the study (p<0.05). After the study, subjects showed lower body weight (-1.8 kg), body fat (-0.94 kg), percent body fat (-0.86%), as well as waist circumference (-4.52 cm), hip circumference (-0.44 cm), waist hip ratio (-0.05), and triceps skinfold thickness (-2.39 mm) compared to those at week 0 (p<0.05). Muscle mass tended to be less compared to week 0, although there was no significant differences between weeks 0 and 4. In conclusion, diet trial with whey protein-rich meal substitute induced weight loss and positively changed body fat parameters and body composition.

The purpose of this study was to evaluate the multilateral weight control program provided by the university health care center for female college students. The program was 8weeks long and composed of nutrition consultation, exercise, and behavior modification. Nutrition education focused on a low calorie and balanced diet, increasing the intake of protein and micronutrients and reducing carbohydrate and fat consumption. Evaluations were made upon completion of an 8-week program and upon follow-up at 6 months after the end of program. A total of 92 women completed the 8-week program, while 20 completed the follow-up survey. Upon completion of the 8-week program, significant decreases in body weight, BMI, body fat (kg), and %body fat were observed, and muscle mass was also reduced. The total energy and carbohydrates intake were also significantly decreased in subjects with weight loss, while the percentage of subjects whose consumption of protein, calcium, iron, vitamin $B_1$, $B_6$, and niacin did not meet the EAR, were decreased. The blood values of glucose, total cholesterol and HDL-cholesterol were decreased. The follow-up survey revealed that the subjects continued to lose weight after completion of the program. In addition, a Mini nutrition assessment revealed that diet quality improved, especially with respect to reductions in the consumption frequency of fried, greasy and salty food. In conclusion, the multilateral weight control program with diet education for female college students was effective for long lasting weight control and improved dietary behavior. Nutrition education for weight reduction should focus on balanced nutrition as well as lowering the total caloric intake.

Objectives: Orthognathic surgery is a surgical procedure performed by intraoral approach with established and safe techniques; however, excessive blood loss has been reported in rare cases. In response, investigative efforts to identify methods to reduce the amount of blood loss have been made. Among such methods, the administration of tranexamic acid was reported to reduce the amount of intraoperative blood loss. However, few studies to date have reported the effect of tranexamic acid in orthognathic surgery under hypotensive anesthesia. The present study aimed to investigate the effect of the administration of tranexamic acid on intraoperative blood loss in patients undergoing bimaxillary (maxillary and mandibular) orthognathic surgery under hypotensive anesthesia. Patients and Methods: A total of 156 patients (mean age, 27.0±10.8 years) who underwent bimaxillary orthognathic surgery under hypotensive anesthesia performed by the same surgeon between June 2013 and February 2022 were included in this study. The following data were collected from the medical records of each patient: background factors (age, sex, and body mass index), use of tranexamic acid, surgical procedures, previous medical history, duration of surgery, American Society of Anesthesiology physical status findings before surgery, intraoperative blood loss as a primary outcome, in-out balance, and blood test results. Descriptive statistics were calculated for statistical analysis, and a t-test and the chi-squared test were used for between-group comparisons. Group comparisons were performed after 1:1 propensity score matching to adjust for confounding factors. Statistical significance was set at P<0.05. Results: Comparison between the groups based on the use of tranexamic acid revealed a significant difference in operation time. Propensity score matching analysis revealed that intraoperative blood loss was significantly lower in the tranexamic acid group. Conclusion: The administration of tranexamic acid was effective in reducing intraoperative blood loss in patients undergoing bimaxillary orthognathic surgery under hypotensive anesthesia.

Background: The VLCD that supplies only 400-800kcal meal per day has a lot of problems and can severely harm the health. Certain herbs are known to the side-effects such as weakness, skin dehydration, and dizziness. If VLCD with meal-replacement containing these hearbs can effectively minimize the side-effects, it make weight management easier and reduce any possible danger the health. Objectives: This prospective, double-blinded study is intended to compare the severity of symptoms induced by VLCD and weight loss between the case group supplied with meal-replacement herbal extracts(n=29) and controlled group supplied with meal-replacement not containing herbal extracts(n=29). This was with 52 volunteers for 4 weeks. The measurements of this experiment were as follows: symptoms caused by patients' subjective judgments, the result of blood test illustratingerol level, total protein etc., and changes in overall weight, fat mass and lean body mass. Result: we concluded that there are no significant differences in weight change between case group and controlled group, and that the total protein at the end of trial was significantly higher in case group than in controlled group, and triglyceride level at the end of trial was lower in case group than in controlled group. As expected, the side-effects such as hair loss and dehydration in skin are also lessin case group than in controlled group.

Diet is important for muscle health and offers a protective effects against the loss of skeletal muscle mass and physical functions with advancing age. We analyzed the relationship between diet, metabolic disease risk, and sarcopenia in Korean female adults using the 2009-2011 Korea National Health and Nutrition Examination Survey (KNHANES). A total of 2038 adult women aged 50-64 years were classified into four groups based on the diagnosis of menopause and sarcopenia. The groups were the non-menopause and non-sarcopenia group (NMNS, n=249), the non-menopause and sarcopenia group (NMS, n=14), the menopause and non-sarcopenia group (MNS, n=1,653), and the menopause and sarcopenia group (MS, n=122). The socio-demographics, anthropometrics, blood profile, and dietary data of the subjects were collected. Those who were in both the sarcopenia groups were more obese (p<0.001), had greater waist circumferences (p<0.001), higher body mass index (p<0.001), and higher obesity rates (p<0.001) after adjustment for covariants. Both the sarcopenia groups also had higher plasma levels of total cholesterol (p<0.001), HbA1c (p=0.001), and vitamin D (p=0.020) than both the non-sarcopenia groups. Both the sarcopenia groups demonstrated a decreased intake of calcium (p=0.05), potassium (p=0.008), and niacin (p=0.008) than both the non-sarcopenia ones. Among the four groups, the NMS group showed the highest levels of total cholesterol, obesity, and lowest intake of micronutrients such as calcium, niacin, and potassium. Thus, muscle mass maintenance through weight control and adequate nutrient intake appears to demonstrate a potential association with preventing sarcopenia in Korean middle-aged women.

Purpose: The inflammatory response due to inflammatory cytokines, bacterial pathogens, and the altered lipoprotein metabolism in patients with periodontitis indicates that infection with periodontal anaerobic bacteria may influence atherogenesis in vitro and in vivo. We aimed to explore the effect of periodontitis concerning clinical and ultrasound markers of early atherosclerosis. Methods: In this case-control study, a total of 30 systemically healthy adults (15 with periodontitis and 15 without periodontitis) over 40 years of age were studied. Periodontitis was determined by measuring the clinical attachment level (CAL) and radiographic bone loss (RBL). Conventional cardiovascular risk factors, including body mass index, serum levels of total cholesterol (TCH), triglycerides (TG), and high-density and low-density lipoprotein (HDL and LDL, respectively) cholesterol were evaluated. Carotid artery intima-media thickness (IMT) was measured using ultrasonography. Results: The mean values of the CAL and carotid IMT were 5.02±0.9 mm and 0.084±0.01 cm vs. 1.6±0.61 mm and 0.072±0.02 cm in the periodontitis and healthy groups, respectively, reflecting statistically significant differences (P=0.001 and P=0.037, respectively). There were statistically significant differences in the serum levels of TCH, TG, and LDL between the 2 groups (P=0.017). The CAL and RBL were positively associated with carotid IMT and serum cholesterol levels, except for HDL, whereas tooth loss was not associated with any markers (P<0.05). Compared to the healthy group, participants with periodontitis exhibited 2.09 times higher odds (95% confidence interval, 1.22-3.59) of having subclinical atherosclerosis. Conclusions: The presence of periodontitis increased the risk of atherosclerosis.
