  • The ultimate aim of this study is to find high-fiber sources among Korean common foods and to develop a high-fiber supplement which can be useful in the therapeutic diet for the diabetic patients. For this purpose the effect of four kinds of seaweeds(mixture of purple laver & sea lettuce : MPS, sea tanle : ST, sea mustard : SM, agar agar : AA) on the glucose and lipid mtabolism were examined. Seven groups of normal and streptozotocin-induced diabetic rats were fed dietary fiber-free control diet or one of experimental diets containing 7% of one of four seaweeds for six weeks. The effects of seaweeds were campared with the effects of fiber-free diet or pectin diet. ST, SM, and AA showed a tendency of improving glucose tolerance improvement by those seaweeds, however, was less than that by pectin. MPS was found to possess a serum cholesterol-lowering effect which is comparable to that of pectin. All the supplementations of seaweeds induced significant increase in fecal steroids excretion. The amounts of fecal cholesterol excretion follwing in feeding of MPS and SM were as high as the level cause by pectin. The excretion of bile acids in the MPS group was much higher than that in the pectin group. Based on its effects of alleviating the diabetic symptoms in the previous study and of improving the glucose tolerance, sea mustard seems to have a benefical effect on glucose metabolism. The serum cholesterol-lowering effect of MPS possibly due to the significant increase in fecal steroids excretion suggests that MPS may be effective in improving abnormalities of lipid metabolism. Therefore, sea tangle and mixture of purple laver & sea lettuce seem to be promising as an effective source of high-fiber supplement for the diabetic patients.

  • This present study was undertaken to evaluate the effects of 5 % chicory extract on serum glucose and lipid metabolism in diabetic rats treated with streptozotocin (STZ). The experimental subjects were divided into 4 groups. : No-fiber , cellulose, insulin, and chicorygroup. The animals were fed ad libitum each of the experimental diets for 4 weeks. The food intake and food efficiency ratio in chicory group was significantly higher than in no-fiber, cellulose, and inulin groups. The reduction of body weight was also significantly lower. The wet weights of cecum and cecal contents were significantly increased in rat fed chicory extract. Total glycated hemoglobin was significantly decreased by chicory extract feeding whereas serum total cholesterol . LDL-choelsterol, and HDL-choelsterol levels were significantly increased. But there were no differences between HDL-choesterol/total cholesterol ratios, LDL-cholesterol/HDL-cholesterol ratios, and atherogenic index. After 10 -hour fast, the levels of hepatic triglyceride and phospholipid were significantly higher in the chicory group than any in other groups. These results indicated that chicory extract is an effective therapeutic regimen for control of metabolic deragements in diabetics.

  • This study was carried to investigate the antidiabetic and lipid metabolism of water extract paecilomyces japonica(PJ) in Streptozotocin (STZ) induced diabetic rats. Diabetes were induced by intravenous injection of STZ at a dose of 42mg/kg dissolved in citrate buffer. The water extract of paecilomyces japonica were orally administrated once a day for 7 days at a dose of 500mg/kg or 1,000mg/kg. The contents of serum glucose, triglyceride(TG), total cholesterol were significantly decreased in PJ treated group compared to the those of STZ-control group. The content of hepatic glycogen and activities of glucose-6-phosphate dehydrogenase(G-6-PDH), glucokinase(GK) were significantly increased, but activity of glucose-6-phoshatase(G-6-Pase) was significantly decreased in PJ treated group compared to the those of STZ-control group. These results indicated that water extract of paecilomyces japonica would have antidiabetic and lipid metabolism effect in STZ-induced diabetic rats.

  • Objectives: The purpose of this study is to investigate the effect of herbal medicine treatment for glucose and lipid metabolic abnormalities caused by polycystic ovary syndrome (PCOS). Methods: We searched for randomized controlled clinical trials (RCTs) in 6 electronic databases and search key words were 'PCOS' and 'chinese medicine' or 'herbal medicine' and 'Metabolic syndrome' or 'glucose' or 'lipid'. The results of the studies were analyzed and the risk of bias was assessed by using Cochrane risk of bias (RoB) tool. Results: We finally selected 7 studies. In 3 of selected studies, herbal medicine was more effective than western medicine in all outcomes and in other 3 selected studies, herbal medicine was partially more effective than western medicine. Conclusions: The study provides a basis for applying herbal medicine treatment to patients with metabolic syndrome caused by PCOS and helps developing a treatment protocol of caring patients with PCOS. But the limitation of this study is that the number of studies included is small and lack of uniformity of outcome indicators made it difficult to observe overall interrelationship between indicators.

  • This study was designed to investigate the effect of dietary Platycodon grandiflorum on plasma glucose and lipid metabolism in $KK-A^y$ mice and STZ-induced diabetic rats. Both plasma triglyceride and plasma cholesterol levels in STZ-induced diabetic rats were significantly decreased by dietary Platycodon grandiflorum feeding for 4 weeks compared to those of control rats, but there were no marked differences in $KK-A^y$ mice. However, for plasma glucose values, Platycodon grandiflorum feeding resulted in a significant decrease in both STZ-induced diabetic rats and $KK-A^y$ mice. Also, dietary Platycodon grandiflorum slightly decreased the postprandial glucose level at 30 and 60 mins during oral glucose tolerance test in $KK-A^y$ mice. Although there was no statistical significance, the fasting plasma insulin levels of Platycodon grandiflorum dieted $KK-A^y$ mice tended to decrease when compared to that of control mice. Therefore, the present results suggested that dietary Platycodon grandiflorum may have a beneficial effect on preventing hypercholesterolemia and hyperlipidemia.

  • Objectives: This study aims to investigate the effects of diabetes mellitus care mixture (DCM) on blood glucose and lipid metabolism in type 2 diabetic mellitus mice. DCM consisted of lagerstroemia speciose, allium hookeri, momordica charantia, amaranthus tricolor, and boesenbergia rotunda, which have been proven to have antidiabetic properties. Methods: In this study, we researched the effects of DCM in type 2 diabetic mellitus mice. C57BLKS/J mouse groups had no treatment, db/db mouse randomly assigned to 2 groups, and treated with distilled water and DCM (200 mg/kg/day). Blood glucose levels and body weight were checked every week. After 4 weeks of treatment, liver function indicators (AST, ALT, and LDH) and lipid metabolites (triglyceride, total cholesterol, LDL-cholesterol, HDL-cholesterol) were measured with a biochemistry analyzer. Diabetic factors (insulin, resistin, and leptin) were measured with ELISA. Results: DCM was decreased blood glucose, diabetic factors, liver function indicators, triglyceride, total cholesterol, and LDL-cholesterol significantly. Also, HDL-cholesterol was significantly increased in DCM group. The bodyweight of DCM group decreased but, no significant difference with the control group. DCM may have the potential to improved diabetes mellitus by regulating blood glucose levels and diabetic factors. Also protecting from diabetic complications by adjusting liver function indicators and lipid metabolites. Conclusions: These results suggest that DCM to be used as an oriental medicine for diabetes, the results of clinical trials are needed.

  • This study aimed to investigate the effects of chromium picolinatec (CrP) supplementation on the glucose and lipid metabolism of rats. Five-week-old male Sprague-Dawley rats were fed a high-fat diet fir 110 days and further treated with CrP or placebos for 6 weeks. The effect of CrP supplementation on body weight, blood glucose, insulin and lipid levels was examined. The results suggested that body weight gain was not significantly different between the control and the CrP supplemented group. Plasma glucose, triglyceride and cholesterol levels in the CrP treated group significantly decreased compared to those of the control group (p < 0.05). The total lipid, triglyceride and cholesterol concentrations in the livers of the CrP treated group significantly decreased compared to those of the control group (p < 0.05). These results indicate that supplementation of chromium picolinate ran reduce triglyceride and glucose concentrations in the blood and total lipid and total cholesterol levels in the liver.

  • The purpose of this study was to investigate the improvement effect of 5% turmeric (Curcuma longa L.) on the blood glucose and lipid metabolism function of streptozotocin (STZ, 45 mg/kg body weight)-induced diabetic rats. Seven-week-old male rats were divided into four groups (n=6), and fed experimental diets containing turmeric meal [basal diet+5% turmeric (BT), basal diet+STZ+5% turmeric (ST)], and control (BD), BS groups (basal diet+STZ). The results of this study, turmeric diet groups (BT, ST) in lipid component as evidenced from the significantly reduction of serum total cholesterol, low density lipoprotein-cholesterol (LDL-cholesterol), atherosclerotic index (AI), cardiac risk factor (CRF), triglyceride (TG), phospholipid (PL), free cholesterol, cholesteryl ester, uric acid, blood glucose, non esterified fatty acid (NEFA), and elevation of high density lipoprotein-cholesterol (HDL-cholesterol). The serum albumin and globulin contents were increased in turmeric supplementation diet than STZ-induced diabetic rats (p<0.05). Concentrations of sodium (Na) and chlorine (Cl) in sera were lower in the turmeric diet than diabetic group. Total calcium (T-Ca), phosphorus (Pi) and potassium (K) concentrations in sera were higher in the BT, ST and BD groups than BS group. In vivo experiments with Sprague-Dawley rats showed that ingestion of turmeric (Curcuma longa L.) were effective in the blood glucose and lipid metabolism functional improvement.

  • Even though coix (Coix lachryma-jobi L. var. ma-yuen) has many physiological effects, since it has been known to cause sterility, farmers avoid using coix bran as a forage for their livestock. Therefore, as the consumption of coix increases, coix bran, which is a by product of pounding process, becomes a serious issue of environmental problem. Present study examined the physiological effects of coix bran in normal and diabetic rats for its possible use as a functional material. The effects of coix bran supplementation on plasma and hepatic lipid profile were evaluated in rats fed one of the following diet for 12 weeks : chow diet ; chow-bran diet (chow diet+25% coix bran), high fat diet and high fat-bran diet (high fat diet+25% coix bran). Additionally, glucose challenge and lipid metabolism in streptozotocin-diabetic rats were also examined. In normal rats, consumption of coix bran remarkably reduced body weight gain in chow or high fat diet fed rats. Additionally, consumption of coix branreduced blood TG, TC and atherogenic index (26%, 24% and 72%, respectively) in chow diet fed rats. Liver TG and cholesterol concentrations were reduced (43% and 49%, respectively) in high fat fed rats by coix bran supplementation. In diabetic rats, fasting blood glucose level was reduced about 25% by coix bran consumption. Also, glucose challenge pattern was improved and resembled normal pattern : it reaches to peak 15~30 minutes after glucose administration and get back to fasting blood glucose level after 90 minutes. Plasma concentrations of TG were elevated in diabetic rats and were reduced to normal level by coix bran supplementation. Liver TG and cholesterol concentrations were also elevated in diabetic rats and reduced to normal level by consumption of coix bran. These results suggest that coix bran may have beneficial effects on blood lipid and glucose level in normal and diabetic rats.
