The present study was conducted to evaluate the dietary fiber intake of 130 subjects, that included 49 subjects(29 form Wonju, 20 from Kangnung) with diabetes mellitus, 23 hyperlipidemia patients, and 58 normal subjects. After the type and amount of foods that a subject took for one day were investigated using the 24-h recall method, the intake of various nutrients and dietary fiber were calculated using a program that already contained the information on dietary fiber contents. The results showed that diabetics from Kangnung who did not undergo dietary therapy had more fat intake that those from Wonju, hyperlipidemia patients, and normal subjects thus, had more energy intake. Also, the crude fiber intake in male and female diabetics from Kangnung were 8.43${\pm}$3.47g and 3.35${\pm}$3.29g, respectively, showing significantly high amounts compared to those of male and female diabetics from Wonju, hyperlipidemia patients, and normal subjects; however, the intake of crude fiber per 1,000 kcal in males and females was not significantly different among the four groups. Also, the dietary fiber intake(14.8-19.8g/day) and the dietary fiber intake per energy unit(7.7-10.9g/1,000kcal) were not significantly different between the four groups. The dietary fiber intakes of diabetics and hyperlipidemia patients were not significantly different from those in normal subjects, and these amounts were significantly lower than recommended levels. Thus, the methods of increasing dietary fiber intake, such as developing low-calorie, high-dietary fiber foods or additives, needs to be researched.

산화적 스트레스는 당뇨병과 관련된 맥관계병변의 전개에 아주 중요한 역할을 한다고 알려져 있다. 따라서 본 실험에서는 streptozotocin(STZ)투여에 의한 당뇨유발쥐를 사용하여 참께함유 항산화성분인 sesamin과 sesamolin의 혈당과 생체내 항산화 방어효소에 미치는 효과에 대하여 알아보고자, 당뇨유발쥐에 0.2% sesamin또는 0.2% sesamolin 함유사료를 3주간 급여하여, 혈당농도, 뇨당농도, 혈청 GOT와 GPT활성, 혈청 및 간조직의 지질과산화물,그리고 GSH함량과 GST활성에 미치는 영향을 조사하였다. STZ투여군의 혈당량은 319.4 $\pm$105.74mg/dL였는데, sesamin급여군은 146.56$\pm$23.99mg/dL, sesamolin급여군은170.74$\pm$105.94mg/dL로 유의하게 감소하였다. 당뇨병쥐의 뇨당농도가 21.16$\pm$13.72 mg/dL였는데, 세사민과 세사몰린 급여시에는 19.52 $\pm$ 8.99 mg/day와 10.93 $\pm$ 7.79 mg/day로 유의하게 감소하였다. STZ투여에 의하여 증가된 GOT와 GPT활성도는 세사민과 세사몰린의 급여에 의하여 GPT활성도만이 유의하게 감소되었다. STZ투여에 의해 증가한 간조직 중의 지질과산화물 생성은 세사민과 세사몰린 급여에 의해 유의하게 감소하였다. STZ투여에 의해 감소된 신장의 GSH함량과 GST활성은 세사민과 세사몰린에 의해 회복되었다. 이상의 결과 세사민과 세사몰린이 신장조직에서 일차적으로 산화된 산화물을 포집하고 GSH를 이용하여 체내의 독성 물질을 전이 분해시키는 작용을 하여 STZ에 의해 유도된 각종 독성을 무독화시켜 신장의 손상을 보호하여 당뇨억제 작용과 함께 항산화 효과를 나타낸 것으로 생각된다.

The purpose of this study was to investigate the dietary compliance and related variables in NIDDM patients. One hundred and fourteen patients at two hospitals in Seoul were interviewed and height, body weight, family history and postprandial blood glucose were analyzed statistically along with the dietary practices. 1) When the degree of dietary compliance was expressed as Tunbridge score, 75% was grouped as satisfactory, 9.7% as Tolerable, and 14.9% belonged to Hopeless group. 2) Calorie intake of the subjects was lower then RDA. Carbohydrate, fat, and protein contributed each 60 : 22 :18. When SFA was used 1, the relative ratio of PUFA : MUFA : SFA was 0.8 : 1.2 : 1. 3) The mean score of knowledge test on diet therapy was 5.6$\pm$2.9 out of possible 12.0 points. 4) Age had significant positive correlation with duration of diabetes(p<0.001), and significant negative correlation with scores of knowledge test on diet therapy was observed(p<0.001). 5) The difference of actual and prescribed calorie intake had positive correlation with PP2 blood glucose level(p<0.05), and significant negative correlation with age(p<0.05). 6) Statiscally significant variables on the practice of diet therapy were the present body weight, protein and carbohydrate intake, age, and sex.

In the current study, inhibitory activity of 8 selected Korean edible plants of Lamiaceae family against $\alpha$-glucosidases, prepared from rat small intestine acetone powder was evaluated. Total flavonoids and oxygen radical absorbance capacity (ORAC) were also investigated. Methyl alcohol extracts of Scutellaria indica (SI) had the highest $\alpha$-glucosidase inhibitory activity relevant for potentially managing hyperglycemia, followed by Clinopodium gracile (CG) and Thymus quinquecostatus (TQ). These 3 species also showed significant antioxidant activity in ORAC system. The $\alpha$-glucosidase inhibitory activity of the extracts was compared to selected phenolics. Among the standard phenolics tested quercetin which was major flavonoid in the extracts had the highest $\alpha$-glucosidase inhibitory activity. CG, TQ, and SI which had high quercetin content and ORAC values also exhibited significant sucrase inhibitory activity. Results suggested that selected 3 Korean Lamiaceae species have the potential development of effective dietary strategy for postprandial hyperglycemia and oxidative stress-linked diabetes complications.

Obesity is a global pandemic that is increasing throughout most of the world. Increases in obesity are not restricted to highly industrialized countries, but have been observed in newly developed and developing countries as well. Obesity is associated with increased risk for non-insulin dependent diabetes mellitus, coronary artery disease, and some types of cancer. Tragically, eliminating food shortages in developing countries may result in substituting heart disease, diabetes, and cancer for malnutrition. There are many approaches to reducing obesity, including dietary modification, surgical interventions, and drug therapies. However, only dietary modification has the potential to be effective on a global scale. Public health measures in the United States have sought to reduce obesity by reducing the intake of dietary fat. While these efforts have succeeded in reducing dietary fat, obesity has continued to increase, suggesting that moderate fat reduction may not be effective. Other proposed diets include low-carbohydrate diets, low glycemic index diets, and very low fat diets. While all of these diets may be effective for some people, they are not satisfactory for public health policy. In fact, the ratio of fat to carbohydrate may not be as important as previously believed. Humans may be well suited to adapt to diets as varied as a high carbohydrate tropical diet consisting mostly of fruits to the high fat Eskimo diet consisting largely of animal foods. Either extreme may be healthful if providing adequate, but not excessive, energy and adequate amounts of micronutrients. Public health measures may need to focuss on reducing the overconsumption of inexpensive and convenient foods.

Earlier we have reported the antidiabetic activity of fresh juice of rhizomes of Zingiber officinale (Z. officinale) and its correlation with 5-HT receptor antagonism. Since 6-gingerol the marker compound of Z. officinale is reported to posses 5-HT anatgonistic activity, the present investigation, was undertaken to find out the concentration of 6-gingerol present in methanolic extract of Z. officinale and its different fractions (petroleum ether, toluene and chloroform). We also evaluated these fractions for antidiabetic activity in streptozotocin (STZ)-induced neonatal type 2 diabetic rats. Fasting glucose and insulin levels in non insulin dependent diabetes mellitus (NIDDM) rats were found to be significantly (P < 0.05) higher than control rats and these were significantly decreased by treatment with methanolic extract of Z. officinale and its fractions. The results of oral glucose tolerance test (OGTT) showed that methanolic extract and its fractions significantly (P < 0.05) decreased both STZ-induced increase in $AUC_{glucose}$ and $AUC_{insulin}$ values in NIDDM groups. Treatment with petroleum ether fraction produced a greater reduction in elevated glucose and $AUC_{glucose}$ levels as compared to treatment with other fractions. Treatment with methanolic extract of Z. officinale and its fractions also produced significant reduction in the elevated lipid, serum glutamate oxaloacetate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT) levels in NIDDM rats. The effect of petroleum ether fraction on elevated lipid, SGOT and SGPT levels was significantly greater as compared to treatment with other fractions. The concentration of 6-gingerol was found to be maximum in petroleum ether fraction (11.430%) and minimum in chloroform fraction (0.973%). The methanolic extract and toluene fraction was found to contain 3.080% and 2.191 %, 6-gingerol respectively. In conclusion, our data suggest that methonolic extract and its fractions possess significant antidiabetic activity in NIDDM rats. The extent of activity appears to be dependent on the concentration of 6-gingerol present in the extract or its fractions.

This study was carried out to provide information on the effect of nutrition education program for diabetic patients at the Guri City's Public Health Center. Subjects of this study were 31 persons(male 7, female 24) who attended all courses of "2002 Diabetes Education Class". They were indicated as the 'education group'(EG). Eating and living habits of EG were investigated before the education. EG's weight and blood glucose (post prandial 2 hours, PP2) were examined as well. EG's PP2 reduction was compared with a 'control group'(CG) who didn't join any course in that class. All of the subjects were non-insulin-dependent diabetes mellitus(NIDDM) patients. EG's average age was 62.4$\pm$8.8. Before taking the course, EG's PP2 was 251.5$\pm$29.6mg/dl, and body mass index(BMI) was 26.3$\pm$2.3 on average. Most of them were stressed out from their daily lives and usually had no exercise. Most people of EG ate meals rapidly and liked sweet and fatty foods. After the course of training, EG's weight and BMI before the training were not decreased significantly. However, all of the EG's PP2s, which were measured 4 times(before the meal at the special lunch session, after 2 hours at this meal, after 2 weeks and 4 weeks dietary assembly), were decreased in comparison with the PP2 which was checked prior to joining the training. EG's average PP2 was more reduced than CG's one. In addition, all groups' PP2s were decreased for 8 weeks. After all, this nutritional education at the public health center was effective in glycemic control for diabetes mellitus patients. Especially, when the dietary assembly as practical training was included in the educational process, the patient's dietary intake and PP2 was improved more effectively. Therefore, this study suggests that nutrition work at public health centers is necessary for the Health Promotion Policy.

The blood components of diabetic patients who visited S- hospital in seoul from January 1982 to June 1983 were compared with the reference levels. Hemoglobin and hematocrit levels of diabetic patients were significantly lower than the reference. The diabetic patients showed 2-3 times higher levels of fasting blood glucose and postprandial -2 hours blood sugar. Levels of blood urine nitrogen and creatine were also significantly higher in the diabetes mellitus and the levels of potassium sodium and chlorine showed no differences although these were decreased gradually in older patients. Lower serum calcium levels were seen in the diabetic patients and this change was more significant at the ages higher than 40. The effect of an active vitamin D on serum-Ca level in diabetic patients was studied in comparison to that of non- diabetic persons. The serum calcium levels were slightly increased in control and insulin- dependent diabetic patients after a week- intake of 1,000mg calcium a day, while the intake of 1,25-dihydroxycholecalciferol ( 1,000 IU per day ) did not increase the serum calcium levels of these groups. Insulin - independent diabetic patients showed the rather lower serum calcium levels after a week- intake of 1,000mg calcium per day. However, the levels were increased after 2-weeks intake of the calcium and a week-in-take of the active vitamin D(1,000 IU/day ). This effect of vitamin D was seen in the groups with lower intake of calcium(500mg/day ) but not in the groups with 1,000mg calcium intake a day.

In this study, body weight levels of glucose, insulin and triglyceride in blood and glucosidase activity of the small intestine were investigated to determine the effect of Sangbaegpitang and Supungsungiwhan on the glucose metabolism of db/db mice. The GLUT4 mRNA of muscle tissue and the Acetyl CoA Carboxylase and the activation rate of GLUT2 mRNA of liver tissue were measured by the reverse transcription-polymerase chain reaction method and by the vitro transcription. The results were obtained as follows: 1. In the Sangbaegpitang administration group, (1) The level of triglyceride was decreased significantly and the glucosidase activity of the small intestine was inhibited remarkably, (2) The amounts of the GLUT4 mRNA in muscle tissue and Acetyl CoA Carboxylase mRNA in liver tissue were increased significantly. (3) Though glucose level in both fasting and non-fasting, were decreased and the insulin level in blood was increased, the results showed no statistical significance. 2. In the Supungsungiwhan administration group, (1) The levels of glucose and triglyceride were decreased significantly in the blood of non-fasting animals. (2) The glucosidase activity of small intestine was inhibited markedly and the amounts of GLUT4 mRNA of muscle tissue and GLUT2 mRNA of liver tissue were increased significantly. (3) The glucose levels in the fasting group were reduced, while insulin level was increased but showed no statistical significance, Based on the above results, our conclusions are as follows: Sangbaegpitang & Supungsungiwhan are thought to be capable of inhibiting the activity glucosidase, the enzyme which influences carbohydrate metabolism in the small intestine of db/db mice(the experimental diabetic model) and delaying the absorption of carbohydrate, thus proving effective on inhibiting the increase of non-fasting glucose level effectively. Futhermore Sangbaegpitang and Supungsungiwhan are though: to be capable of preventing the composition of free fatty acids by restoring the production of GLUT4 mRNA of muscle tissues and GLUT2 mRNA of liver tissues. Those results suggests that above prescriptions can be applied to non-insulin dependent diabetes mellitus in order to improve insulin resistance.
