This study aimed at the effect on serum glucose and lipid profiles according to carbohydrate / lipid intake ratio in Korean 191 NIDDM patients. Most of NIDDM patients belong to under 50-64 years. As carbohydrate intake level increased, lipid intake level decreased. The group of higher carbohydrate / lipid intake ratio shows significantly high in fasting glucose level and postprandial glucose in NIDDM patients. The higher carbohydrate / lipid intake ratio the higher dietary linoleic and $\omega$-3 fatty acid level but not in dietary $\omega$3/$\omega$6 ratio. Serum HDL decrease inhigher carbohydrate lipid intake ratio group. Serum total lipid and PUFA level decrease according to ditary total lipid intake decrease in men but not significantly different.

Background: Antihyperglycemic effects of Panax ginseng berry have never been explored in humans. The aims of this study were to assess the efficacy and safety of a 12-wk treatment with ginseng berry extract in participants with a fasting glucose level between 100 mg/dL and 140 mg/dL. Methods: This study was a 12-wk, randomized, double-blind, placebo-controlled clinical trial. A total of 72 participants were randomly allocated to two groups of either ginseng berry extract or placebo, and 63 participants completed the study. The parameters related to glucose metabolism were assessed. Results: Although the present study failed to show significant antihyperglycemic effects of ginseng berry extract on the parameters related to blood glucose and lipid metabolism in the total study population, it demonstrated that ginseng berry extract could significantly decrease serum concentration of fasting glucose by 3.7% (p = 0.035), postprandial glucose at 60 min during 75 g oral glucose tolerance test by 10.7% (p = 0.006), and the area under the curve for glucose by 7.7% (p = 0.024) in those with fasting glucose level of 110 mg/dL or higher, while the placebo group did not exhibit a statistically significant decrease. Safety profiles were not different between the two groups. Conclusion: The present study suggests that ginseng berry extract has the potential to improve glucose metabolism in human, especially in those with fasting glucose level of 110 mg/dL or higher. For a more meaningful benefit, further research in people with higher blood glucose levels is required.

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.

The goal of this study was to find out the effective diet prescription for the exercises. To accomplish this purpose, we investigated the effect of free-fatty acid diet (FFAD) on two groups of the K technical high school soccer players; one group with 7 members for normal diet (NORD) and another group with 7 members for high-fat diet (HFD). HFD group was fed far three days before the game. Results were as follows: i) Blood glucose level was increased with statistical significance in HFD group (P<.01) compared to the NORD group. After plying game, the glucose level was increased in the both groups ii) The contents of free-fatty acid (FFA) was significantly increased in HFD group (P<.0001) compared to the NORD group. After playing game, the FFA level was also increased in both groups iii) The levels of T-C, HDL-C and LDL-C were slightly increased in both NORD and HFD groups after playing game, while the TG level was slightly decreased. However, the differences were not significant. These results imply that HFD may not affect the level of seam lipids. Overall, the level of glucose and FFA were increased, but other types of lpids were not changed. From these studies, we observed the increase in the level of glucose and FFA but not other sew lipid. These results indicate that HFD may induce the body energy-utilizing system during long-lasting exercise such as playing soccer game.

A 10-week feeding trial was conducted to investigate the effects of dietary glucose, dextrin and starch on growth and body composition of juvenile starry flounder. Triplicate groups of fish (average weight, 9.7 g) were fed iso-nitrogenous (53% CP) and iso-caloric (3.8 kcal/g diet) diets containing 20% glucose, 20% dextrin and 5-25% alpha-potato starch with 5-14% lipid levels. Survival was not affected by dietary carbohydrate. Weight gain, feed efficiency and protein efficiency ratio of fish fed the diet containing 20% glucose were the lowest among all groups. The best weight gain was observed in fish fed the diets containing 20% dextrin. Growth and feed efficiency were not affected by dietary -potato starch level. Lipid contents of whole body and liver were not affected by dietary glucose, dextrin and starch at the same level. However, the lipid contents tended to decrease with increasing dietary starch level and those of fish fed the diets containing 5% alpha-potato starch were significantly higher than those receiving 10-25% alpha-potato starch. Liver glycogen content and hepatosomatic index tended to increase with increasing dietary starch level. These results indicate that juvenile starry flounder are able to efficiently utilize dextrin and -potato starch compare to glucose in diets and that alpha-potato starch could be incorporated up to 25% in the diet for optimum growth by juvenile starry flounder.

The ability of exercise and buckwheat diet to modify plasma glucose and cholesterol levels in streptozotocin-induced diabetic rats has been studied. Diabetic rats were fed corn starch as a control diet or buckwheat as an experimental diet for 4 weeks. One group of rats were exercise-trained to swim for 60 min/day, 6 days a week. Plasma glucose levels of sedentary rats both on the control diet and on the buckwheat diet were significantly increased from 367.0$\pm$33.6 mg/dl to 545.0$\pm$38.7 mg/dl and from 380.3$\pm$18.9 mg/dl to 540.5$\pm$36.6 mg/dl, respectively. However, this large increase of plasma glucose was not seen in exercised rats on the buckwheat diet (from 345.0$\pm$25.6 mg/dl to 391.4$\pm$34.7 mg/dl). The total plasma cholesterol level was not affected by either diet or exercise. The HDL-cholesterol level tends to increase due to the buckwheat diet or an exercise, but not with a significant increase. Our results suggest that the buckwheat diet is beneficial in lowering the plasma glucose level only when diabetic rats ar exercised.

Objective: The purpose of this study is to investigate the elevated blood glucose levels in the postoperative period are associated with an increased risk of deep wound infection in diabetic individuals undergoing lumbar spine surgery. Methods: Of 2896 patients who underwent lumbar spine operations by one surgeon between 1993 and 2002, 329(11.4%) were diabetics. The rate of deep wound infections in diabetic patients was 6.4%, versus 3.2% for nondiabetics. 152 patients had their operation before implementation of the protocol and 177 after implementation. Charts of the diabetic patients were reviewed. Mean blood glucose levels were calculated from documented results of finger-stick glucometer testing. Results: Twenty-one diabetic patients suffered deep wound infection. Infected diabetic patients had a higher mean blood glucose level through the first 2 postoperative days than noninfected patients($230{\pm}6.9$ versus $175{\pm}3.8mg/dL$; p<0.003) and had a long operation time($216{\pm}57.9$ versus $167.5{\pm}42.2$ minute; p<0.05). Multivariable logistic regression showed that mean blood glucose level for the first 2 postoperative days, long operation time, and use of the instrumentation(p<0.02) were all related predictiors of deep wound infection. Institution of a protocol of postoperative continuous intravenous insulin to maintain blood glucose level less than 200mg/dL was began in september 1997. This protocol resulted in a decrease in blood glucose levels for the first 2 postoperative days and a concomitant decrease in the proportion of patients with deep wound infection, from 8.3%(11/132) to 5.1%(10/195) (p<0.02). Conclusion: The incidence of deep wound infection in diabetic patients is reduced after implementation of a protocol to maintain mean blood glucose level less than 200mg/dL in the immediate postoperative period.
