This study was carried out to investigate the effects of nutrition education on blood glucose in type 2 diabetic patients with low income. There were 50 (27 male and 23 female) study subjects with type 2 diabetes under national medical support, and the monthly income in most of them was less than 500,000 won. Anthropometric measurement, biochemical blood indices, food intake, dietary habits, and nutrition knowledge of the subjects were investigated before nutrition education. Nutrition education was conducted 6 times within 12 weeks. After nutrition education, the glycosylated hemoglobin was significantly decreased (male: $8.4{\pm}1.6%$ to $8.0{\pm}1.7%$, female: $8.3{\pm}1.6%$ to $8.0{\pm}1.3%$) and the total cholesterol was also significantly decreased in both groups. The group of female resulted in a significant decrease in fasting blood glucose ($169.7{\pm}28.2$ mg/dL to $152.8{\pm}22.0$ mg/dL) and triglyceride ($177.8{\pm}56.3$ mg/dL to $162.3{\pm}36.1$ mg/dL), but the group of male did not show a significant decrease in fasting blood glucose and triglyceride. Nutritional knowledge and dietary habit scores of the subjects were significantly improved after nutrition education. The results demonstrate that nutrition education for type 2 diabetic patients with low income are effective in improving their blood glucose.

We investigated whether or not Schisandra chinensis (SC), a traditional herbal medicine, has protective effects against alcohol-induced fatty liver and blood alcohol clearance. Two tests focused on acute intoxication and chronic ethanol treatment were carried out. For the chronic ethanol treatment test, rats were fed ethanol by intragastric administration everyday for 8 weeks to induce alcoholic fatty liver. Ethanol treatment significantly increased blood alcohol concentration at 90 min after acute ethanol intoxication. Compared with the two ethanol-treated groups, rats administered ethanol along with SC extracts showed an approximately 13% increased blood alcohol clearance rate at 360 min. Chronic ethanol treatment significantly increased serum and hepatic triglyceride (TG) levels, and caused fatty degeneration of liver. Ethanol treatment also elevated the serum total-cholesterol (TC) level. However, after feeding of ethanol plus SC extracts, ethanol-induced elevation of hepatic TG levels reversed, whereas elevation of serum TG and TC levels was not observed after treatment with SC extracts. Ethanol treatment significantly increased ${\gamma}$-GT, aspartate aminotransferase, and alanine aminotransferase activities after 8 weeks. Compared with the ethanol-fed group, rats administered ethanol plus SC extracts for 4 weeks showed attenuated fatty degeneration as well as decreased hepatic function test values. SC administration also significantly increased intracellular lipid accumulation in hepatocytes and reduced steatosis score and hepatic TG levels, as measured by biochemical and histolopathological analyses. Our results indicate that the protective effects of SC are accompanied by a significant decrease in hepatic TG levels, thereby suggesting SC has the ability to prevent ethanol-induced fatty liver, by reducing hepatic TG and enzyme levels in alcoholic rats.

Objectives: The aim of this study is to determine arterial stiffness levels as measured by brachial-ankle pulse wave velocity (baPWV) and to identify the association between arterial stiffness and inflammatory markers, in healthy adults over 50 years old. Methods: The study population consisted of 4617 persons over the age of 50 years who participated in the baseline survey of the Dong-gu Study, which was conducted in 2007 and 2008. Arterial stiffness was measured using baPWV. A multiple regression analysis was performed to assess the relationship between conventional cardiovascular risk factors and inflammatory markers, including white blood cell (WBC) counts, high-sensitive C-reactive protein (hs-CRP), and gamma glutamyltransferase (GGT). Results: After adjustment for conventional cardiovascular risk factors including sex, age, smoking status, body mass index, systolic blood pressure, fasting glucose, hypertension or diabetic medication, total cholesterol, triglycerides, uric acid, and alanine aminotransferase, baPWV was significantly associated with WBC counts (${\beta}$=0.158, p<0.0001), hs-CRP (${\beta}$=0.244, p=0.026), and GGT (${\beta}$=0.003, p<0.0001). Conclusion: This study shows that arterial stiffness correlates with inflammatory markers. Arterial stiffness may be used as a composite risk factor to identify persons with higher risk for cardiovascular disease. Additionally, arterial stiffness may be a marker for future cardiovascular disease and a target for prevention.

Effects of Gastrodiae Rhizoma on serum lipids and body fat in rats fed high-fat diet supplemented with 10% (w/w) lard during 11-week experimental period were investigated. Ninety-six male rats were randomly divided into eight groups: A, negative control (lard 10%); B, positive control (lard 10%+rat chow+5 brix water extract); C, lard 10%+1% G. Rhizoma powder; D, lard 10%+5% G. Rhizoma powder; E, lard 10%+2 brix 50% ethanol extract; F, lard 10%+10 brix 50% ethanol extract; G, lard 10%+2 brix water extract; H, lard 10%+10 brix water extract. Body weight gain, although slightly higher in groups A, B, and G, did not differ significantly among dietary groups. Weights of liver, spleen, kidney, and testis were significantly higher among dietary groups. Serum total cholesterol and triglyceride concentrations were markedly higher in both control groups than group H (p<0.05). Serum HDL concentration was significantly higher in group E, and lower in group A (p<0.05). Serum LDL+VLDL concentration was significantly lower in groups E, G, and H (p<0.05). Serum testosterone level was slightly higher in groups E, D, and H. Blood glucose level was significantly higher in groups B and G, whereas lower in group H (p<0.05). Epididymal fat pad (EFP) was markedly higher in control groups than G. Rhizoma diet-fed groups (p<0.05). The results indicated that decrease in serum lipids (TC, TG, LDL+VLDL) and body fat, and increase in serum HDL and testosterone levels were higher in groups E and H extracts than groups fed G. Rhizoma powder.

Obesity and being overweight are strongly associated with the development of metabolic disease such as diabetes, hypertension, dyslipidemia. High-fat diet (HFD) is one of the most important factors which cause obesity. In this study, C57BL/6 mice were treated with a HFD for 22 weeks in order to induce obesity and hyperglycemia. Twenty-two weeks later, body weight and plasma glucose level of the HFD group were significantly increased, compared with the normal diet (ND) group. Intra-peritoneal glucose tolerance test (IPGTT) showed glucose intolerance in the HFD group compared with the ND group. These results confirmed that a HFD induced obesity and hyperglycemia in C57BL/6 mice. Plasma levels of triglyceride (TG) and total cholesterol (TC) were increased in the HFD group compared with the ND group. Hepatic levels of TG and TC were also increased by a HFD. To investigate the alteration of lipid metabolism in liver, proteins which are related to lipid metabolism were observed. Among lipid synthesis related enzymes, fatty acid synthase (FAS) and glycerol phosphate acyl transferase (GPAT) were significantly increased in the HFD group. Apolipoprotein B (apoB) and microsomal triglyceride transport protein (MTP), which are related to lipid transport, were significantly increased in the HFD group. Interestingly, protein level and phosphorylation of AMP-activated protein kinase (AMPK), which is known as a metabolic regulator, were significantly increased in the HFD group compared with the ND group. In the present study we suggest that HFD may physiologically increase the proteins which are related with lipid synthesis and lipid transport, but that HFD may paradoxically induce the activation of AMPK.

The antihyperlipidemic and glycemic control effects of mycelia of Inonotus obliquus including protein-bound polysaccharides extract were investigated. In high fat diet-induced obese C57BL/6J mice, the mycelia of Inonotus obliquus including protein-bound polysaccharides extract showed significant decrease in epididymal fat tissue weight, blood triglyceride and VLDL level, triglyceride and total cholesterol level in liver, serum insulin and HOMA-IR level and AUC. Oral glucose tolerance test glucose level reduction were 4.9% (M150L; ${\beta}$-glucan 1.303 mg/kg bw), 9.5% (M150; ${\beta}$-glucan 2.606 mg/kg bw) after 180 min of glucose loading compared to H-C group. Besides, the mycelia of Inonotus obliquus including protein-bound polysaccharides extract treatment significantly increased glycogen contents in liver and adiponectin level in high fat diet-induced obese mice. In conclusion, the results showed that the mycelia of Inonotus obliquus including protein-bound polysaccharides extract possesses significant antihyperlipidemic and glycemic control effects in C57BL/6J mice.

This study was designed to examine the effects of Compositae plants on plasma glucose and lipid levels in streptozotocin (STZ) induced diabetic rats. Sprague-Dawley rats were randomly assigned to 5 groups: normal, STZ-control and three experimental groups [Artemisia iwayomogi (A. iwayomogi), Atractylodes lancea (A. lancea), and Taraxacum mongolicum (T. mongolicum)]. Normal and STZ-control group were fed an AIN-93 diet and three experimental groups were each fed a modified diet containing 10% compositae powder for 4 weeks. The plasma glucose levels at 4 weeks of A. iwayomogi, A. lancea, and T. mongolicum groups were significantly lower than STZ-control group. The A. iwayomogi and A. lancea groups had significantly suppressed hypertrophy of liver and kidney. The hematocrit levels of A. lancea and T. mongolicum group were significantly lower than STZ-control groups. The total cholesterol and triglyceride levels and atherogenic index (AI) of A. lancea group were significantly lower than STZ-control group. Intake of Compositae plants may be effective in antihyperglycemia by lowering blood glucose levels. The A. iwayomogi, A. lancea, and T. mongolicum can be beneficial for the diabetic complications and damage from the lipid peroxidation.

This study was performed to identify the association between the metabolic syndrome and the biochemical measurements and nutrient intakes. A total of 1,431 people (533 males, 898 females) aged over 45 years living in Andong rural area participated in this study in 2003. Plasma aspartate aminotransferase (AST), alanine aminotransferase (ALT), $\gamma$-glutamyl transferase ($\gamma$-GT) and thiobarbituric acid reactive substances (TBARS) levels in metabolic syndrome were significantly higher than those in normal group. In multiple logistic regression, those biochemical measurements were found to be positively associated with the metabolic syndrome as the adjusted odds ratios (OR) 1.839 (p<0.001) by AST, 2.302 (p<0.01) by ALT, 2.143 (p<0.001) by $\gamma$-GT, and 1.874 (p<0.001) by TBARS. We also found that the increased level of those measurements tended to be strongly associated with high triglyceride among the metabolic syndrome components. However, the nutrient intakes between the metabolic syndrome and the normal group were not significantly different. Also, we could not find any nutrient intakes significantly associated with the metabolic syndrome, except high carbohydrate intake (>70% of kcal) compared to normal intake (55~70% of kcal) showed OR 0.781 (p<0.05). In analyzing the association of nutrient intakes with metabolic syndrome components, we found that the calorie intake was negatively associated with abdominal obesity (OR 0.696, p<0.05) and high fat intake (>25% of kcal) was positively associated with low HDL-cholesterol (OR 1.864, p<0.05). This study revealed that the biochemical measurements, such as plasma AST, ALT, $\gamma$-GT, and TBARS, are associated with metabolic syndrome, but considering the nutrient intakes, we suggest that further studies are needed to identify the associations.

Purpose: The purpose of this study was to evaluate the dietary potassium intake, Na/K intake molar ratio, consumption of 18 food groups, and foods contributing to potassium intake of Korean adults as well as the relationships among quartile of potassium intake level and blood pressure, blood biochemical index. Methods: This study was conducted using the Korea National Health and Nutrition Examination Survey, 2007~2010. The total number of subjects was 20,291. All analyses were conducted using a survey weighting to account for the complex survey design. Results: Overall average intakes of potassium were 2,934.7, 3,070.6, 3,078.1, and 3,232.0 mg/day, and they significantly increased by year in Korean adults. The average dietary potassium intake was close to adequate intake (AI), whereas that of women was considerably lower than the AI. The Na/K intake molar ratio in males (2.89~3.23) was higher than in females (2.62~2.95). The major food groups contributing to potassium intake were vegetables, cereals, and fruits/meats. The two major foods contributing to potassium intake were polished rice and cabbage kimchi. The rankings of food source were as follows; polished rice > cabbage kimchi > potato > oriental melon > sweet potato > seaweed > radish > apple > black soybean. In 50~64 year old females, systolic blood pressure (SBP) significantly decreased (p < 0.01) and HDL-cholesterol significantly increased (p < 0.05) as potassium intake increased. Triglyceride (TG) was significantly higher in the other quartile of potassium intake level than in the first quartile (p < 0.05). Conclusion: In conclusion, our study suggests the need for an appropriate set of dietary reference intakes according to caloric intake by sex and age groups and for development of eating patterns to increase potassium intake and decrease sodium intake.
