Purpose: Changes in eating habits and malnutrition due to dysphagia are important health problems for older adults. This study investigated the effects of an educational program aimed at improving diet quality in community-dwelling older adults at risk for dysphagia in South Korea. Methods: We assessed 27 individuals in the experimental group and 26 individuals in the control group between September and October 2015. All participants were aged 65 years or older and were at risk for dysphagia. A combined diet and exercise program was applied to the experimental group (n = 27) for six weeks. We examined changes in participants' eating habits and their knowledge and attitudes concerning dysphagia risk. The nutrition intake of all participants was measured before and after the intervention using 24-hr dietary recall. Results: There was a significant increase in knowledge of dysphagia risk in the experimental group, with scores increasing from 3.7 to 7.1, out of 10 points (p < 0.001). There were also significant improvements in eating habits after the intervention in the experimental group, with scores increasing from 21.9 to 28.3, out of 36 points (p < 0.001). The attitude score of participants in the experimental group increased significantly, from 15.2 to 16.7, out of 20 points (p = 0.016). Conclusion: Developing educational programs can help older adults living in the community lead a healthier lifestyle and improve their ability to manage their diet.

The purpose of this study was to investigate dietary behaviors and health-related lifestyles of adult visitors at a public health center in Gyeonggi urban area. A survey using questionnaire was conducted with 949 visitors at Seongnam public health centers from June to August, 2012. The data from 905 respondents were analyzed by gender, consisting of 322 males and 583 females, and age group, consisting of 243 low-age group (LA), 312 middle-age group (MA), 350 high-age group (HA), aged 20 to 30 years, 31 to 50 years, and 51 to 69 years, respectively. Average Body Mass Index was 23.0, which increased with age, and education level was high in LA. 59.0 percent of the subjects had various diseases, and the incidence of hypertension was the highest, followed by allergy, hyperlipidemia, diabetes mellitus, joint rheumatism. Incidence rates of chronic disease increased with age, which were lower than those from 2011 Korea National Health and Nutrition Examination Survey (KNHANES). Weekly drinking frequency rate and smoking rate decreased with age, and exercise performing rate was high at male and HA, which showed the same tendency as KNHANES. Female and HA showed more healthy dietary behaviors such as restricting salt, sugar, oily foods, foods containing food additives, calorie, caring for balanced diet, and referring to nutrition label. Subjects chose stress as the first factor, followed by diet, exercise, etc., among 13 suggested factors which strongly influence on human's life-span. In general, public health center visitors, especially female and HA, showed better dietary behaviors and health-related lifestyles compared with KNHANES.

Controlling dietary behaviors and health-related lifestyle habits is important to manage non-insulin dependent diabetes mellitus (NIDDM). If NIDDM is not treated properly, the prevalence of macro-vascular complications (MC) may increase. The goal of NIDDM therapy is to maintain normal concentrations of blood glucose and lipid profiles by having regular meals, controlling alcohol drinking, quitting smoking, and performing physical exercise regularly. This study was performed to investigate the dietary and health-related lifestyle habits and blood parameters of NIDDM patients of both genders and compared these characteristics between the patients with and without MC. Our results show that the subjects with MC compared to without MC and the female patients than the males controlled their diets more regularly, tended to regulate the number of meals better, and smoke less than those without MC. Although plasma lipid profiles were not significantly different between the genders and between the subjects with and without MC, the men had higher blood glucose and plasma tHcy concentrations than the women and plasma tHcy concentration was higher in the female subjects without MC. These results imply that the male patients of NIDDM without MC might have more problems in maintaining their blood glucose. In addition, smoking may be the most important life-style factor influencing some blood parameters like blood glucose, HbAlc, and total cholesterol in the NIDDM patients.

This study was designed to investigate the effects of weight reduction and changes in serum lipid composition using a commercial uncooked powdered food (UPF) diet on 27 obese hyperlipidemic women over a period of 12 weeks. We replaced the standard breakfast and dinner of each of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Their body compositions were measured using a body fat analyzer. Also, we conducted hematological, clinical and lipid profile analyses of their blood. Their intake of energy, lipid and protein significantly decreased as the subjects started to take UPF, but their intake of vitamins and minerals, other than iron, increased. Due to the energy intake decrease, the subjects' weight, body fat and waist circumference significantly decreased. Among the lost weight the percentage of the body fat was high. We judged that this process of losing weight was successful in obese hyperlipidemic women. Serum HDL-cholesterol gradually increased and serum total-cholesterol, LDL-cholesterol, triglyceride levels showed gradual decreases. When obese hyperlipidemic women replaced two of three meals with UPF for 3 months, we were able to see useful changes like decreased body fat and serum lipid. Complete judgment on the usefulness of UPF may be difficult but if people take a standard meal once a day and replenish their iron by taking UPF twice a day, we assume that replacing UPF with balanced regular meal not be a problem in nutritional status. Our results show that UPF is effective in the diet therapy of obese hyperlipidemic women.

In order to investigate the preventive and therapeutic of royal jelly on diabetes, the levels of blood glucose and serum lipids as well as the number of blood cells were determined in streptozotocin(STZ) diabetic rats. Rats were divided into seven groups. The RJ group was administered royal jelly and the STZ group was treated with streptozotocin to induce diabetes. To determine the preventive effect, diabetes was induced after administration of royal jelly for 2 weeks in group RS1/RS2. In group SR1/SR2 diabetic rats were administered royal jelly for 2 weeks to investigate the therapeutic effect. After 3 weeks, the body weight was reduced in STZ and SR1 groups and food intake was increased in the STZ, RS1 and SR1 groups. The blood glucose level was similar to the control group in the RJ, RS1 and RS2 groups and there was no effect in the other groups. The total lipid and triglyceride level were lower in the SR1 group as compared to STZ, and the total cholesterol level was higher in the STZ group. The index of atherogenesis was lower in the RJ and SR1 groups compared to the normal group. The number of red blood cells and hemoglobin was higher in the RJ and SR1 groups and the number of white blood cells was higher in the RJ and SR2 groups.

Applications of bone marrow-derived mesenchymal stem cells in gene therapy have been hampered by the low efficiency of gene transfer to these cells. In current transduction protocols, retrovirus particles with foreign genes make only limited contact with their target cells by passive diffusion and have short life spans, thereby limiting the chances of viral infection. We theorized that mechanically agitating the virus-containing cell suspensions would increase the movement of viruses and target cells, resulting in increase of contact between them. Application of our mechanical agitation for transduction process has increased the absorption of retrovirus particles more than five times compared to the previous static method without changing cell growth rate and viability. The addition of a mechanical agitation step increased transduction efficiency to 42%, higher than that of any other previously-known static transduction protocol.

Sogeunjung-tang (S-tang) is a traditional Korean medicine that has been used for the therapy of anxiety disorder in a variety of clinical situations. However, no study has investigated this effect. The aim of this study was to investigate the effectiveness of S-tang for reducing depression in animal model. The anti-depressant effect of S-tang was investigated in ICR mice by using forced swimming test (FST). After FST, we analyzed the blood biochemical parameters from blood. The immobility time was significantly decreased in the S-tang oral administration or pharmaceutical acupuncture group compared with the control group at 14 days (p < 0.05). The anti-depressant effect of S-tang was higher than that of fluoxetine (a classical anti-depressant). S-tang or fluoxetine significantly decreased the creatine kinase and lactate dehydrogenase level compared with the control group (p < 0.05) but not glucose, protein, and blood urea nitrogen level. Further investigation of S-tang as a potential pharmacologic agent in the management of depression related anxiety is warranted.
