Corosolic acid (CA), a triterpenoid compound isolated from Lagerstroemia speciosa L. (Banaba) leaves, exerts anti-inflammatory effects by regulating phosphorylation of interleukin receptor- associated kinase (IRAK)-2 via the NF-κB cascade. However, the protective effect of CA against endotoxic shock has not been reported. LPS (200 ng/mL, 30 min) induced phosphorylation of IRAK-1 and treatment with CA (10 μM) significantly attenuated this effect. In addition, CA also reduced protein levels of NLRP3 and ASC which are the main components of the inflammasome in BMDMs. LPS-induced inflammasome assembly through activation of IRAK-1 was down-regulated by CA challenge. Treatment with Bay11-7082, an inhibitor of IκB-α, had no effect on CA-mediated inhibition of IRAK-1 activation, indicating that CA-mediated attenuation of IRAK-1 phosphorylation was independent of NF-κB signaling. These results demonstrate that CA ameliorates acute inflammation in mouse BMDMs and CA may be useful as a pharmacological agent to prevent acute inflammation.
This study was conducted to assess diet-related health appraisal for cardiometabolic diseases of the college students in Gyeonggi-do. The survey data obtained by 21 questionnaire(6 general characteristics and 15 food behaviors) given to 90 students, 41 males and 49 females. The average age of the subjects was 22.2 years old for the male students and 20.9 years old for the female students(p<0.001). Among the subjects, 35 males and 47 females' height, weight and percentage of body fat were measured using bioelectrical impedance(Inbody 720). The average height, weight, Body Mass Index and percent body fat of the subjects were 175.7cm, 69.5kg, 22.4 and 16.9% for males and 162.0cm, 53.5kg, 20.4 and 27.7% for females, respectively (p<0.001). Male students had a higher prevalence of smoking compared with female students(p<0.001). Females had higher intake frequency of fruits than males(p<0.05). Males had higher intake frequency of fishes than females(p<0.05). Male students had higher number of side dishes at mealtime compared with female students. There were no difference between the sexes in intake frequency of dairy, ramyeon, rice with whole grain, 3-layered pork belly, processed meat, soft drinks, soy products and fast food. Also, there were no difference between sexes in number of vegetables per day, frequency of eating out, prevalence of eating kimchi at every meal. Cardiometabolic risks were calculated by 'Diet-related health risk appraisal'. Male students had higher cardiometabolic risks(hypertension, hyperlipidemia, diabetes, obesity, abdominal obesity) than female students(p<0.001). Appropriate nutritional education for college male students may help to prevent cardiometabolic diseases in the future.
These studies were performed to investigate the effect of antioxidants, melatonin (MLT) and ascorbic acid (AA), on the diabetic complications. In the experiment, twenty-four Sprague Dawley rats were divided into four groups; Group 1: no treatment (control) (n=6), Group 2: Streptozotocin (STZ; 65 mg/kg b.w. ip) treatment (n=6), Group 3: MLT (10 mg/kg b.w. ip) treatment (n=6), Group 4: ascorbic acid (AA: 40 mg/kg b.w.ip) treatment (n=6). Rats were sacrificed and collected designated samples (blood, kidney, pancreas) at the 21 days after antioxidant treatment (the 8th week after STZ injection). There was no significant change of body weight during the experiment period in the all groups. The concentration of blood glucose was decreased below 200 mg/dl in MLT. The concentration of HbA$_1$c level was decreased significantly in MLT (7.3$\pm$0.66%) compared with STZ (15.1$\pm$1.58%) (p<0.01). No significant change of SOD activity in the RBC and kidney was found in the all groups. In the pancreas, MLT (1.42$\pm$0.17 U/ml) and AA(1.65$\pm$0.16 U/ml) decreased SOD activity compared with STZ (4.10$\pm$0.27 U/ml). However, there was no significant difference among MLT and AA. The level of malondialdehyde(MDA) as an indicator of lipid peroxydation was decreased in MLT compared with STZ in the plasma, kidney and pancreas(p<0.01). These findings suggest that melatonin could prevent the complications of diabetes mellitus.
Objectives : The aims of this study were to evaluate whether gastric contractility could be measured by bowel sound of rats, and whether gastrointestinal side effect of any herbal restoratives would be related with their inhibition of gastric contraction. Methods : Streptozotocin (STZ)-induced diabetic rats were used as a gastric hypocontraction model. At the time of 6 weeks after induction of diabetes, 2mL of normal saline (NS) and 2mL of extract solution each containing 125mg/kg of Bojoongikki-tang (BJ), Sipjeondaebo-tang (SJ), Youngkaechulgam-tang (YG) were given to Normal (NR) and diabetic rats (DR), respectively. Bowel sound was recorded for 30 minute in fasting, and 120 minute of their administration. Gastric motility index was serially calculated with the ratio of accumulated potentials of post-administration/fasting state every 10 minutes. Results : Gastric contractility between NR and DR could be significantly distinguished by bowel sound auscultation. BJ had a decreasing effect, SJ had a bidirectional effect, and YG had an increasing effect on gastric contractility measured by bowel sound auscultation. Conclusions : BJ showed the possibility of inhibitory effects on gastric contraction. So, before administration, a gastric motility test should be recommended to prevent possible side effects in patients with gastric hypocontractility.
PURPOSE: The purpose of this study is to understand the difference in the risk factors of coronary artery disease (CAD) between Korean and American CAD patients to determine the discriminant factor for each group, as well as to provide useful information to be reflected in the national concern of health. METHODS: Data were collected from 248 Korean and 107 American CAD patients who underwent either percutaneous coronary intervention or coronary artery bypass grafting. By using t-test and $X^2$-test, risk factors were compared between the Koreans and Americans. To elucidate which risk factor was the most discriminant for each group, logistic regression analysis was performed. RESULTS: All risk factors, except diastolic blood pressure, showed a significant difference between the two groups. $X^2$-test showed statistical significance with respect to the smoking rate between the female groups. Moreover, there was a statistically significant difference between the two groups regarding blood total cholesterol (TC) and triglyceride, and between the male groups, here was a statistically significant difference with respect to blood high-density lipoprotein cholesterol (HDL). Diabetes mellitus (DM) was the most discriminant factor for Korean patients while TC/HDL is the most discriminant for the Americans. CONCLUSION: The characteristics of CAD risk factors were determined to be different between Koreans and Americans in this study. TC/HDL was a discriminant factor for Americans while DM was a discriminant factor for Koreans. This result implies that DM should primarily be given attention to prevent CAD in Korean adults.
Objectives: This study was intended to provide the base of developing countries' Health Partnership Strategy by investigating the Paraguay's awareness level of health and analyzing the actual state. Methods: The data was collected from 11 government employees, 20 hospital staffs, 26 local residents on Asunci$\acute{o} $n, Paraguay in February, 2012. The method of the study was the questionnaires consisting of 62 questions including 7 questions of general features, 3 questions of awareness on maternal health care, child health care, planned parenthood program, 52 questions of awareness on health. The questionnaires was translated into Spanish which is local language in Paraguay. Results: The results of this study are summarized as follows; 1) The most important awareness on maternal healthcare, child healthcare, planned parenthood program was providing child health care. 2) The most important awareness to prevent non-health behavior was sufficient nutrition. The most important awareness to reduce the rate of chronic disease was diabetes. The most important awareness to eradicate communicable disease was HIV/AIDS. 3) The most important awareness to provide healthcare service was vaccination. 4) The most important awareness on healthcare delivery system was policy. The most important awareness on health education was student's health education. 5) The most important awareness to strength healthcare capacity was developing domestic economy. Conclusion: The results of this study suggest that awareness levels on health are high against low health behavior status in Paraguay. But awareness on health can lead to health behavior by healthcare system. Therefore, it has to induce the healthcare network and system by injecting public health funds, infrastructure, human resources on prevention of disease and healthcare management.
Objectives: The aim of this study was to investigate the factors related to dental caries and periodontal disease in Korean adults. Methods: The subjects were 5,149 adults over 19 years old who participated in the 5th Korea National Health and Nutrition Examination Survey 2012. Data were analyzed by chi-square test and logistic regression analysis using SPSS 18.0 statistical package program. The questionnaire consisted of 17 questions of independent variables and 2 kinds of dependent variables including dental caries and periodontal diseases by direct interview. The independent variables included 5 questions of general characteristics, 3 questions of health behavior, 5 questions of oral health behavior, and 4 questions of chronic diseases diagnosed by the doctors. Results: The prevalence rate of dental caries was higher in those who did not regularly work out and did not receive regular checkups including dental floss and dental brush use. The prevalence rate of periodontal diseases was higher in male adults, smokers, and those who were obese and had diabetes mellitus, poor oral health care habit without using dental floss and inter-dental brush. Conclusions: In order to prevent the dental caries in the adults, it is very important to do regular exercise and regular dental checkup. The best ways of dental caries prevention include tooth brushing after meal with use of dental floss and inter-dental brush. This study suggests that dental health promotion can be enhanced by smoking cessation, ideal body weight maintenance, timely tooth brushing after meal, and use of dental floss and inter-dental brush.
The purpose of this study was to compare the validity of obesity indices among the body mass index (BMI), waist circumference (WC), and body fat percentage (BF%), and to determine which is the most useful index to predict the risk of chronic diseases of elderly people. This study was conducted as a cross-sectional study at welfare centers in Seoul. The total number of subjects was 261 (68 men and 193 women) with age ${\geq}60$ years. The distribution of obesity using 3 obesity indices in the subjects with hypertension, diabetes, or arthritis was BF%>WC>BMI in elderly men and WC>BF%>BMI in elderly women. In elderly women, odds ratios (ORs) for hypertension in BMI and WC quartiles were significantly increased in quartile 2 and 3 (p<0.05). The ORs for hypertension, hyperlipidemia, and arthritis in BF% quartiles were significantly increased in quartile 3 and 4 (p<0.05). The BF% was sensitive obesity index for predicting the occurrence of chronic disease in men, and the WC was sensitive index in women. Our results suggested maintaining BMI less than $23.5kg/m^2$, WC less than 82 cm, and BF less than 35% in order to prevent chronic diseases in elderly women.
Objective : Mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke like episodes (MELAS) syndrome is a progressive neurodegenerative disorder. The typical presentation of patients with MELAS syndrome includes features such as mitochondrial encephalomyopathy, lactic acidosis, and stroke like episodes. Other features, such as seizures, diabetes mellitus, hearing loss, cardiac disease, short stature, endocrinopathies, exercise intolerance, and neuropsychiatric dysfunction are clearly part of the disorder. Approximately 80% of patients with the clinical characteristics of MELAS syndrome have a genetic mutation. This progressive disorder is reported to have a high morbidity and mortality. This case report is intended to estimate clinical effects of oriental meedicinal treatment of MELAS syndrome. Methods : A 44 year old female patient diagnosed as MELSA syndrome was treated with general oriental medicinal therapy including acupuncture, moxibustion, cupping, pharmacupunture and herbal medication in 20XX in Wonkwang Medical Center Gwangju. And the changes in symptoms and signs were evaluated as time dependently. Results : Although there is currently no curable treatment and MEALS syndrome is tend to progress, our treatment showed improvement in general weakness, gait disturbance and pain in the patient. Conclusion : Our case report suggests that various oriental medicinal treatment could be effective for improvement of MELAS syndrome and may represent a new potential therapeutic approach to control the disease. It could be applied to improve general condition, prevent relapse, enhance the quality of life and reduce complaints in the patient.
This study was performed to produce WBM (wheat and barley mixture) bread containing molokhia powder with quality characteristics and antioxidant activities. Analysis of the chromaticity of WBM prepared with molokhia powder showed that; the lightness and redness were decreased, but yellowness was increased. In mechanical properties, hardness, gumminess, and chewiness were significantly increased as the amount of molokhia powder was increased. However, cohesiveness was significantly decreased. In sensory evaluation, WBM bread containing 1.5% of molokhia powder (MB1.5) showed an overall high preference level. The total polyphenol content of molokhia powder EtOH extract and MB1.5 were 29.19 and 58.18 mg TAE/g, respectively. The total flavonoid contents of molokhia powder EtOH extract and MB1.5 were 20.62 mg and 33.25 mg RE/g, respectively. The radical scavenging ability ($IC_{50}$) of DPPH ($IC_{50}$) for molokhia powder EtOH extract and MB1.5 was 31.04 and $58.18{\mu}g/mL$, respectively while that of ABTS was 33.25 and $54.15{\mu}g/mL$, respectively. The ${\alpha}-glucosidase$ inhibitory effects of molokhia powder EtOH extract and MB1.5 were 494.88 and $814.88{\mu}g/mL$, respectively. MB bread containing 1.5% molokhia powder showed antioxidative effects and ${\alpha}-glucosidase$ inhibitory activity, meaning that not only molokhia but also MB1.5 bread has the potential to prevent chronic degenerative diseases such as diabetes.
