The purpose of this study was to establish an association between glycemic index (GI), glycemic load (GL), dietary carbohydrates and diabetes with the context of the current population dietary practice in Korea. The subjects of 3,389 adults (male 1,430, female 1,959) were divided into normal (serum fasting glucose < 100 mg/dL), impaired glucose tolerance (100 ${\leq}$ serum fasting glucose < 126 mg/dL), diabetes (serum fasting glucose > 126 mg/dL) by serum fasting glucose. Anthropometric and hematologic factors, and nutrient intakes, dietary glycemic index (DGI), dietary glycemic load (DGL) were assessed. Multiple logistic regression model was used to determine the odds ratios (ORs) and 95% confidence intervals for relationship of DGI, DGL, carbohydrates intakes, and diabetes. DGI and DGL were not significantly correlated with impaired glucose tolerance and diabetes. However, the risk of impaired glucose tolerance and diabetes showed a tendency to increase as increase of DGI after multivariate adjustment (age, education, income, region area, diabetes family history, smoking, drinking, exercise, energy intake) in male. The risk of impaired glucose tolerance and diabetes showed a tendency to increase in the DGI 71.1-74.8 after multivariate adjustment in female. DGL was inversely related to impaired glucose tolerance and diabetes in male. In female, however, DGL was positively related to impaired glucose tolerance and diabetes. In particular, the risk of diabetes increased positively in level of DGL 260.5, and remained after multivariate adjustment (Q5 vs Q1：2.38, 0.87-6.48). When percent energy intakes from carbohydrates were more than 70%, the risk of impaired glucose tolerance and diabetes increased in both male and female. In particular, when percent energy intakes from carbohydrates were more than 69.9%, the risk of diabetes increased positively in male (Q4 vs Q1：2.34, 1.16-4.17). In conclusion, above 70% energy intakes from carbohydrates appeared to be a risk factor of diabetes. It seemed that the meal with high GI and GL value must be avoided it. And also, the macronutrients of the meal must be properly balanced. In particular, it may be said that it is a preventive way for treatment of the diabetes to avoid eating carbohydrates of much quantity.

Objective: The purpose of this study was to determine serum antioxidant nutrients and the relationship between serum antioxidants and risks of chronic diseases in obese Korean children Methods: Normal weight Korean school children (0=170), mean age of 11.5$\pm$1.5, and obese (body fat mass > $28\%$) children (0=176), mean age of 11.0$\pm$1.8, were recruited Fat mass ($\%$) was determnined by Bioelectrical Impedance (BEI), and body mass index (BMI) was calculated Fasting blood was collected to measure serum antioxidant nutrients, vitamin A, vitamin E and zinc. Serum lipid profiles including total cholesterol (TC), high density cholesterol (HDL) and triglyceride (TG), and blood glucose, glutamic oxaloacetic transaminase (GOT), and glutamic pyruvic transaminase (GPI) were also determined. Differences in serum blood measurements between obese and normal children were assessed by independent t test. Pearson's correlation analysis was used to determine the relationship between variables. Results: Blood glucose, GPT, total cholesterol, and triglycerides concentrations were significantly higher among obese boys, compared to normal boys (p<005). Significantly lower concentrations of serum vitamin E, after adjustment for TG and TC, was shown in obese boys (0.26 mg/mg) and obese girls (0.31 mg/mg), compared to normal boys (0.36 mg/mg) and girls (0.38 mg/mg) (p<0.05). Fat mass ($\%$) was negatively con-elated with serum vitamin A and vitamin E. Conclusion: Obese Korean children showed insufficient serum vitamin E concentration and increased risk for diabetes, atherosclerosis, and liver disease. Since lower vitamin E concentration was negatively con-elated with atherogenic index, improved vitamin E status in children may decrease the risk of atherosclerosis later in life.

Anesthetic agents are useful in inducing the anesthesia for surgical operations and various biological experiments, but they can disturb the body homeostasis and cause the stress in animals. Much efforts have been directed on reducing such side effects of anesthesia. In this work, we measured the serum ACTH, corticosterone and glucose concentration in rabbits to compare the degree of stress induced by two commonly-used anesthetics, ketamine, xylazine, and the combination of xylazine and ketamine. 1. The anesthesia was induced in about 10 min in the rabbits treated with xyalzine, ketamine and xylazine-ketamine. The duration of complete loss of righting reflex were 12, 13 and 115 min in the groups treated with xylazine, ketamine and xylazine-ketamine, respectively. 2. Serum ACTH concentrations in all treatment groups were higher than those in control group. At 30 min after the administration of the drugs, serum ACTH levels in ketamine-treated group were significantly higher than those in control, xylazine- and xylazine-ketamine-treated groups. However, at 1, 2, 5 and 9 hours after the drug administration, serum ACTH levels in xylazine-treated-group were higher than those in control. 3. Serum corticosterone levels in xylazine- and xylazine-ketamine-treated groups were lower than those in control or ketamine-treated groups at 0.5 and 1 hour after the administration. However, at 5 and 9 hours after the administration, serum corticosterone levels in xylazine- and xylazine-ketamine-treated groups were significantly higher than those in ketamine-treated group or control. 4. Serum glucose levels transiently increased to 3 times of the pre-injection levels at 0.5 and 1 hours after the administration in xylazine or xylazine-ketamine-treated groin, but were not changed in control and ketamine-treated group. These results indicate that xylazine-induced stress lasts longer than ketamine-induced, suggesting that the difference in stress-related hormone levels during anesthesia could be due to the differences in modes of actions of individual drugs used and the depth of anesthesia.

This study was designed to investigate a natural medicinal multi-plants extract (BG515), which consisted of multi extracts of Mori folium, Rehmannia glutinosa Liboschitz, Dioscorea japonica, Lycii fructus, and Astragalus radix, on blood glucose, insulin levels, and serum malondialdehyde (MDA) concentrations in streptozotocin-induced diabetic rats. Streptozotocin (STZ) induces a type 1 diabetes mellitus in rats. Type 1 is usually characterized by the presence of islet cell autoantibodies (ICA), autoantibodies to insulin (IAA), and autoantiboides to glutamic acid decarboxylase (GAD), which identify the autoimmune process that leads to $\beta-cell$ destruction. Thirty-five male Sprague-Dawley (SD) rats weighing $150\sim170g$ each (6 weeks old) were randomly divided into one control (Group A) and 4 STZ-induced diabetic groups, and were subjected to one of the following treatment for 12 weeks. Groups A and B were fed basal diets and Group C, D, and E received the same diets as groups A and B, but with supplements of 150 mg/kg, 300 mg/kg, and 600 mg/kg of BG515 orally for 12 weeks, respectively. Diabetes was induced in Groups B, C, D, and E by intravenous injection of 45 mg/kg of STZ per body weight in sodium citrate buffer (pH 4.5) via the tail vein. In the BG515 groups, we found increases in serum insulin levels, compared to the STZ-control group, but these data were not significant. In contrast, blood glucose and serum MDA concentrations decreased in the BG515 groups compare to the STZ-control group. At the 5th week, in all the BG515 administered groups, there were decreases in serum blood glucose levels compared to the STZ- control group, and this activity was very strong in the BG515-1 group at the 12th week. These results suggest that natural bio-complex compounds (BG515) may slightly suppress STZ-induced changes in serum MDA concentration via the maintenance of serum insulin levels, due to the prevention of $\beta-cell$ and glucagon destruction by STZ.

The glucose tolerance and pancreatic insulin secretion response to glucose in sheep fed on germinated sorghum grain were determined using an intravenous glucose load. Twelve male Thin Tail sheep (an Indonesian native sheep, 12 months old and 14.8 kg average body weight) were divided randomly into sorghum grain-based (S), germinated sorghum grain-based (G) and maize grain-based (C) diets. Sheep were maintained at the same daily intake levels of metabolizable energy and crude protein in the diets throughout the experimental period. After two months of the experimental conditions, each diet group was subjected to an intravenous glucose load experiment in which five doses of glucose (0, 10, 20, 40 and 80 mg/kg BW) were injected to estimate the rate of glucose removal from blood and the pancreatic insulin secretion response. For each sheep and each glucose load dose, the incremental blood serum glucose and insulin concentrations above pre-injection concentration were calculated as serum glucose and insulin response areas. At all glucose doses, sheep fed on S diet had a greater (p<0.05) glucose response area compared to those of sheep fed on G and C diets. Likewise at all glucose doses, the insulin response area was smaller (p<0.05) in sheep fed on S diet than in sheep fed on G and C diets. The glucose and insulin response areas in sheep fed on G and C diets differed slightly. It was concluded that the portion of maize grain in the ruminant ration could be substituted by germinated sorghum grain.

The purpose of this study was to assess the effects of Cordyceps militaris extract supplementation on the improvement of blood glucose, lipid compositions and hepatic functional enzyme activities in the serum of streptozotocin(STZ, 50 mg/kg BW, IP injection)-induced diabetic rats fed the experimental diets for 5 weeks. The concentrations of blood glucose and lipid compositions(total cholesterol, ${\beta}$-lipoprotein, free cholesterol, cholesteryl ester, triglyceride and phospholipid) and atherosclerotic index in serum were significantly lower in the DM+CM group than in the DM group, whereas the ratio of HDL-cholesterol concentration to total cholesterol in the DM+CM group were higher than in the DM group. The activities of hepatic functional enzymes(aminotransferase, LDH and ALP) in serum were lower in the Cordyceps militaris extract administration group(group DM+CM) than in the hyperglycemic DM group. The results shown above suggested that Cordyceps militaris extract supplementation effectively improves blood glucose and atherosclerosis in the serum of diabetic rats.

The insecticide p-nitropheny diethyl thiophospate is alse known by the symbol E.605 and a legion of trade names including “parathion”. The insecticide is widely used in agriculture, but it is highly toxic and now clear that parathion behaves like a cholinergic drug by inhibiting the enzyme cholinesterase. In order to know acute toxicity and the changes of glucose concentrations and activity according to time lapsed in female mice given orally single with the half dose to $LD_{50}$ of parathion, glucose contents and cholinesterase activities in serum as well as cholinesterase activities in whole brain and spinal cord were investigated, otherwise median lethal dose ($LD_{50}$) of parathion given orally against female mice was determined. The results obtained were summerized as follows ; 1. $LD_{50}$ value of parathion given orally to female mice was 7.1mg/kg(95% confidence limits, 3.8-13.1mg/kg) 2. The inhibition rate of cholinesterase activities in serum of parathion-administrated mice according to time lapsed were peakly decreased to 61% after 30 minutes in comparison to control group, but activities were completely recovered after 48 hours. 3. The inhibition rate of cholinesterase activities in whole brain of parathion-administrated mice according to time lapsed were peakly decreased to 49% after 2 hours in completely recovered after 24 hours. 4. The inhibition rate of cholinesterase activities in spinal cord of parathion-administrated mice according to time lapsed were peakly decreased to 57% after 2 hours in comparison to control group, but activities were completely recovered after 48 hours. 5. The changes of glucose contents in serum of parathion-administrated mice according to time lapsed and in directly after death due to parathion poisoning were no significantly difference.

Objectives : To prove the channel-tropism theory of herbal medicines on diabetes mellitus as emaciation-thirst disease in Korean Medicine Theory, we investigated the selective therapeutic effects of Mori Cortex Radidus (MCR), Schisandrae Fructus (SF), Anemarrhenae Rhizoma (AR) for the upper emaciation on different organs in high fat and high sucrose (HF/HS) feeding-induced prediabetic mice. Methods : Diabetes in C57BL/6 mice was induced by the administration of high fat (45 kal%) and high sucrose (32 kal%) for 8 weeks, and them treated with each extract at 250 or 500 mg/kg body weight for 4 weeks (once a day). Oral glucose tolerance test and body weight was measured once a week. Insulin, total cholesterol, triglyceride, ${\gamma}GTP$, GOT and GPT were measured in the sera of all mice. Histopathological changes of different organs, lung, heart, pancreas, stomach, liver, and kidney were observed by H&E staining. Results : The results revealed that MCR extract inhibited the impaired glucose tolerance and lung damage, and increased serum insulin levels in HF/HS-induced prediabetic mice. SF extract inhibited the impaired glucose tolerance and lung damage, increased serum insulin levels, and decreased serum triglycerige levels. Meanwhile, AR extract inhibited the impaired glucose tolerance and lung damage, and decreased serum levels of insulin, total cholesterol and triglycerige levels. Conclusions : These results demonstrated that MCR, SF, and AR extract as the upper emaciation herbal medicines were followed their channel-tropism theory like a lung, and may have a selective therapeutic potential for control of diabetic stage.
