This study was designed to investigate whether Sasa borealis leaves extracts (SLE) may inhibit yeast ${\alpha}-glucosidase$ and ${\alpha}-amylase$ activities and postprandial hyperglycemia in STZ-induced diabetic mice. Freeze-dried SLE was extracted with 70% methanol and followed by a sequential fractionation with dicholoromethan, ethylacetate, butanol, and water. Both ethylacetate and butanol fractions showed high inhibitory activities against the ${\alpha}-glucosidase$ and ${\alpha}-amylase$ enzymes. The $IC_{50}$ of ethylacetate and butanol fractions against ${\alpha}-glucosidase$ were 0.54 and 0.63 mg/mL, respectively, indicating a greater inhibition effect than acarbose (0.68 mg/mL) (p<0.05). Likewise, the two fractions exhibited a smaller $IC_{50}$ against ${\alpha}-amylase$, compared with acarbose (p<0.05). However, the yield of ethylacetate fraction of SLE was relatively small. Postprandial blood glucose testing of normal mice and STZ-induced diabetic mice by starch soln. loading (2 g/kg B.W.) showed that postprandial blood glucose level at 30, 60, and 120 min were markedly decreased by single oral administration of SLE butanol fraction (200 mg/kg B.W.) in both normal (p<0.0l) and diabetic mice (p<0.0l). Furthermore, the incremental area under the curve (AUC) was significantly lowered via SLE administration (5,745 versus 12,435 $mg{\cdot}mim/dL$) in the diabetic mice (p<0.0l). The incremental AUC in normal mice corroborated the hypoglycemic effect of SLE (p<0.0l) found in the diabetic mice. These results suggest that SLE may delay carbohydrate digestion and thus glucose absorption. In addition, SLE may have the potential to prevent and treat diabetes via its ability on lowering postprandial hyperglycemia.

An inhibitory activity against ${\alpha}-glucosidase$ was identified in extract of an edible lichen, Umbilicaria esculenta. The inhibitor was very stable retaining above 95% of its original activity when treated with heat, acid and alkaline conditions, and some hydrolytic enzymes. Partially purified inhibitor showed strong inhibition against disaccharide hydrolytic enzymes of mammalian and mold origin, but weak or no inhibition against polysaccharide hydrolytic enzymes except glucoamylase. The inhibitor suppressed elevation of blood glucose level in rats after oral administration of soluble starch or sucrose.

An inhibitory activity against ${\alpha}$-glucosidase was identified in extracts of medicinal lichens, Parmelia austrosinensis and P. praesorediosa. The extracts retained almost all of their original activities when treated with heat, acid and alkaline conditions, and some hydrolytic enzymes. Partially purified inhibitor showed strong inhibition against disaccharide hydrolytic enzymes of mammalian and mold origin, but weak or no inhibition against polysaccharide hydrolytic enzymes except glucoamylase. The inhibitors from the two Parmelia sp. showed almost same retention time in HPLC. The inhibitor suppressed elevation of blood glucose level in rats after oral administration of soluble starch or sucrose.

The hypoglycemic and hypotensive effects of Polygonatum odoratum in non-insulin dependent diabetes metlitus (NIDDM) patients were investigated in this study. Sixty five NIDDM patients were divided into two groups: hospital diet (HD), Polygonatum odorat um diet (PD). HD group was provided with the diabetic diet used in a hospital and PD group consumed the Polygonatum odoratum added to the HD. The index of obesity, the level of fasting blood pressure (systolic and diastolic), fasting and postprandial blood glucose of NIDDM patients of the PD group were significantly lowered after the experimental period of 4 weeks. The levels of the plasma glucose, lipid and index of obesity was measured. The tendency of elevating the level of HDL-cholesterol and lowering the levels of triglyceride, LDL-cholesternl and total cholesternl were also noticed in NIDDM patients of the PD group. The results showed that Polygonatutn odoratum could be an important dietary source to control hyperglycemia and hypertension and that the plant could be recommended as a preventive or therapeutic agent for NIDDM patients.

Dumping syndrome is a known complication of gastric surgery in adults, but a very rare disease in the pediatric population. We report on a case of dumping syndrome in a 19-month-old child, who underwent gastrojejunal feeding tube insertion for the treatment and prevention of gastroesophageal reflux and frequent aspiration pneumonia. At 17 months of age, 2 months after the beginning of gastrojejunal tube feeding, postprandial diaphoresis, palpitation, lethargy, bloating, and diarrhea occurred, and a single episode of convulsion with hypoglycemia were noted. Early and late dumping syndrome was confirmed by an abnormal oral glucose tolerance test with early onset hyperglycemia followed by delayed onset hypoglycemia. Diet therapy including uncooked corn starch then improved the postprandial diaphoresis, abnormal glucose levels, and her nutritional status. We conclude that dumping syndrome may be considered as a complication of gastrojejunal tube feeding in a child.

The purpose of this study is to examine to control of glucose level and the occurrence of chronic complications of diabetes by compliance groups with health care regimen The subjects were consisted of 300 out patients with type 2 diabetes mellitus from beginning of March through the end of April in 2001, who visited at the endocrinology department at Kangnam St. Mary's Hospital of Catholic University in Seoul. The patient's compliance level with health care regimen was assessed at questionnaire. However, the blood glucose level and the occurrence of chronic complications of diabetes were assessed at medical record review. The data were analyzed by SAS program for chi square test and t-test. The results were as follows. 1. Significant differences were found among the factors such as duration of diabetes, the number of participation of diabetes educational program, job, smoking, self monitoring of blood glucose and the methods of diabetes therapy between high and low compliance groups. High compliance group patients had a diabetes longer than low compliance group patients. High compliance group patients more frequently attended the educational program and checked themselves monitoring blood glucose than low compliance group patients. Also, they did not work recently, smoked less and got more insulin injection therapy compared to low compliance group patients. 2. No significant differences were found among the result of fasting blood glucose. 2-hour postprandial blood glucose, and $HbA_{l}c}$ between high and low compliance groups. 3. The occurrence rate of macrovascular complications of chronic complications of diabetes were lower, however, the occurrence rate of microvascular complications were higher in high compliance group than in low compliance group with health care regimen.

Impaired glucose tolerance(IGT) & Impaired fasting glucose(IFG) were standardized in 1979 by the National Diabetes Data Group and the World Health Organization as a risk factor for type 2 diabetes. The main clinical significance of IGT & IFG shows some risk factors on type 2 diabetes, cardiovascular disease and component of the metabolic syndrome. In 1997, the American Diabetes Association(ADA) proposed the new classification and diagnostic criteria for diabetes, which wss striction on the diagnostic baseline of Diabetes from 140 mg/dl to 126 mg/dl. This is because that the early diagnosis and treatments can prevent chronic complications. In the oriental medicine, Gamiyookmigihwang-tang has been using for the treatments of Diabetes including IGT & IFG; however, there have not been enough studies about the effect of the glycemic control objectively. So clinical studies have been performed on a mild DM(Diabetes Mellitus) patient with IGT and IFG in order to investigate whether there is hypoglycemic effect of Gamiyookmigihwang-tang. Prior to the study, for two weeks fasting blood sugar(FBS) and postprandial 2hrs(PP2hrs) glucose were checked. in addition ECG, T-cholesterol, TG, HbA1c levels were measured; then, Gamiyookmigihwang-tang has administrated for 4 weeks. and FBS, PP2hrs, T-cholesterol, TG, HbA1c were measured again after the herb medicine treatment. FBS, PP2hrs glucose levels and other measuring levels (T-cholesterol, TG, HbA1c) were decreased by the administration of Gamiyookmigihwang-tang. Gamiyookmigihwang-tang has hypoglycemic effects on a mild DM patient with IGT and IFG.

Nonobese NIDDM patients were studied were studied with respect to changes in visceral protein status, serum glucose and lipids and insulin secretion capacity before and after intake of enteral formula. Patients with renal or hepatic disease, gastrectomy, malabsorption, weight gain over past 6 months and poorly controlled blood glucose level were excluded. Eighteen patients served as case and administered, in addition of their usual diet, 400ml of enteral formula for 8 weeks. Another 18 patients participated in controls and had usual food intake for 8 weeks. In the begining, the levels of fasting and postprandial glucose, glycated hemoglobin, triglyceride, HDL, LDL, total cholesterol, albumin, total protein and transferrin and glucose response area on oral glucose tolerance test were not different between two groups. The response areas of insulin, C-peptide and free fatty acid and serum IGF-1 level were higher in the case than in the control group. Energy intake of patients given enteral formula exceeded their estimated energy requirements(108%) and they consumed a mean of 112g protein per day. Patients given enteral formula showed an increase in body weight(4.4%), serum transferrin(10%), IGF-1(13%) and triglyceride(34%) while controls showed no changes in those parameters at 8 weeks compared to initial values. There were no significant changes after 8 weeks in the levels of glucose, glycated hemoglobin, HDL, LDL, total cholesterol, total protein and albumin and response areas of glucose, insulin, C-peptide and free fatty acid in both groups compared to initial values. This study suggests that nutrition supplement with enteral formula can increase body weight and visceral protein status in nonobese NIDDM patients without changes in blood glucose. However, excessive calorie intake could temporarily increase serum triglyceride. In addition, this study indicates that serum transferrin and IGF-1 are more sensitive indicators to changes of protein intake than serum albumin and total protein.

The purpose of this study was to observe the effects of cellulose and pectin on glucose and plasma lipid concentrations in healthy women. Eight female collage students were participated voluntarily. All subjects received a fiber-free control diet (CD), cellulose diet (CED), pectin diet (PTD) with each diet for a period of three days with a 4 day interval. The food intake of subjects were monitored every day and plasma level of glucose, triglyceride, total cholesterol were determined at last day. Blood glucose, plasma triglyceride, total cholesterol were measured at fasting state and 30, 60, 90, 120, and 180 minute after consuming each diet. Plasma glucose concentrations (AUC: Area Under the Curve) of pectin diet was $122.7{\pm}4.0mg/dl$ and that of cellulose diet was $147.6{\pm}8.4mg/d$, but they were significantly lower than in comparison with those of control diet ($197.1{\pm}11.6mg/dl$) (p<0.05) Plasma triglyceride concentrations of the CED ($-83.9{\pm}22.2mg/dl$) PTD ($-9.7{\pm}26.1mg/dl$) showed gradual decrease after each test diet feeding but not significantly different in each dietary fiber added diet (p<0.05). Plasma cholesterol concentrations of the CD was not significantly different in PTD, but PTD was significantly lower than the CED until 3 hours after consuming each test meal (p<0.05). In conclusion, in spite of total cholesterol was reduced only by pectin, glucose and triglyceride were lower than control diet in dietary fiber intake. But there were no significant differences each dietary fiber.

This study was performed to determine the effect of Takju(Korean turbid rice wine) lees on the serum glucose level in streptozotocin-induced diabetic rats. 24 Sprague-Dawley male rats were divided into three groups: normal control(NC), diabetic control(DC) and diabetic rats(DS) were fed on experimental diet and water ad libitum for 4 weeks. DS diet was containing 20% Takju lees. Body weight gain and food Efficiency Ratio(FER) were significantly lower in DC and DS than NC. DS tended to have higher weight, weight gain and FEF than DC nevertheless food intake. Therefore Takju lees could possibly complement casein as a protein source. Gastrointestianl transit time in DS significantly decreased than NC while not significantly than DC. Serum lipid profiles and AST. ALT and amylase were not significantly different between diabetic DC and DS. Blood glucose was measured at fasting state and 30, 60, 90 and 120 minute by oral glucose tolerance test, DS tended to lower the mean(${\pm}$ SE) incremental blood glucose concentrations than DC and was significantly low at 120 min. But incremental AUG(area under the curve) of postprandial glucose response was not significantly different. In conclusion, in spite of high contents of carbohydrate Takju lees perhaps have a benefit effect on the diabetes.
