  • Type 1 diabetes mellitus commonly occurs in childhood and adolescence, although the prevalence of type 2 diabetes mellitus in these age groups is now being increased in the western world and Korea. Diabetic nephropathy developing in 15-25% of subjects with type 1 diabetes mellitus and in similar or higher percentage of type 2 diabetes mellitus patients is the leading cause of end-stage renal disease worldwide. Although prepubertal diabetic duration may contribute less to the development of microvascular complications than pubertal and postpubertal duration, diabetic nephropathy in susceptible patients almost certainly begins soon after disease onset and may accelerate during adolescence, leading to microalbuminuria or incipient DN. Type 1 diabetes is commonly associated with a period of hyperfiltration followed by the development of persistent microalbuminuria after as little as 7-10 years of type 1 diabetes. Microalbuminuria is associated with pathologic lesions that are so advanced as to overlap with those seen in patients with overt proteinuria and declining kidney function, therefore, microalbuminuria currently considered the best clinical indicator of overt diabetic nephropathy risk. This review covers the natural history and renal manifestations of diabetic nephropathy in children and adolescents.

  • The purpose of this study was to identify some anthropometric characteristics related to the incidence of diabetes mellitus in Korea. The subjects were 165 male and female patients aged 30 to 70 years who had been diagnosed with diabetes mellitus for less than five year, recruied from eight different hospitals in Seoul, Korea. Weight, height, waist circumference, hip circumference and triceps skinfold thickness were measured. Weight before diagnosis of diabetes was also surveyed. The body mass index(BMI) of diabetic patients before diabetic diagnosis was significantly higher than that of reference values. Fifty percent of patients had BMI values greater than 25kg/$m^2$, and female patients were somewhat fatter than male patients. Since many subjects were overweight before diagnosis, obestty could be regarded as a risk factor for the incidence of diabetes mellitus. However, waist-hip ratios(WHR) fell within the normal range, so WHR may not be regarded as an important risk factor for NIDDM in Korea. This study suggests that the risk factors of onset of diabetes in Western populations may not be applicable to the Korea population. More study is needed to clarify the risk factors of Korean diabetes.

  • The hypoglycemic effects of butanol(BuOH) fraction of Polygonatum odoratum with vitamin E in streptozotocin(STZ)-induced diabetic rats were investigated. Sprague-Dawley rats weighing 200-230g were devided into five groups, and four groups induced diabetes mellitus by the STZ injection(45mg/kg b.w.) into the tail vein : Normal, diabetic-control, and three diabetic experimental groups(p. odoratum group, P. od-vit. E group and Vit. E group). All groups were fed on a AIN-76 diet, and the experimental groups were orally administered with the BuOH fraction of Polygonatum odoratum(500mg/kg b.w.) and vitamin E(10mg/kg b.w.) for 14 days. The body weight, diet intake and organ weights were monitored. The plasma levels of glucose, insulin, cholesterol, triglyceride, HDL-cholesterol and aspartate and alanine aminotransferase activities were analyzed. The levels of glycogen in liver and muscle, cholesterol in liver were determined. The malondialdehyde(MDA) levels in liver, kidney and lung were assayed. The body weight loss was seen in P. odoratum group, P. od-vit. E group, Vit. E group and diabetic control group, while the loss in P. odoratum group was much less than that in the diabetic control group. The plasma glucose levels were significantly lowered in P. odoratum group compared to diabetic control group. The plasma insulin levels were noticeably higher in P. odoratum and Vit. E groups. The rats in P. odoratum and P. od-vit. E group showed higher liver glycogen levels than in the diabetic control group. The MDA levels in liver, kidney and lung were also significantly reduced in P. od-vit. E and Vit. E groups compared to the diabetic control group. The results suggest that the administration of BuOH fraction of Polygonatum odoratum along with vitamin E reduced blood glucose levels and peroxidative tissue damage in STZ-induced diabetic rats, showing the possibility of preventive and therapeutic use of the wild edible plant to the diabetes mellitus.

  • Riboflavin status of 17 insulin-dependent diabetic mellitus(IDDM) patients in growing period was evaluated as a function of energy intake and expenditure, biochemical nutritional status and diabetic control indicators. Compared with recommended dietary allowances for Koreans(RDA, 1989), only 35.3% of subjects was at good levels of all nutrients intakes and 52.9% of subjects was below normal level of height and weight. Nutrients consumed below RDA levels were energy(=88.5% of subjects), niacin(64.7%), iron(52.9%) and protein(23.5%) respectively. The riboflavin status was within normal range by urinary riboflavin excretion but 17.6% of subjects was evaluated as showed riboflavin deficiency by erythrocyte glutathione reductase activity coefficient(EGRAC). Correlation between riboflavin intake, urinary riboflavin excretion, EGRA level and diabetic duration were not statistically significant. Correlation analyses indicated that EGRA level was inversely correlated with thiamin, niacin and cabohydrate intake. No significant correlations were found between the EGRA and glycosylated hemoglobin A1(HbA1) (r=-0.464, p=0.129). From this study, it is suggested that IDDM subjects need to maintain balanced diet containing nutrients above RDA for individual activity during growing period. It needs more study whether the current recommended riboflavin allowance is adequate for diabetic patients.

  • Hyperhomocysteinemia has been shown to be associated with increased risks for macrovascular angiopathy. The present study was conducted to document the relationship between plasma homocysteine levels and the presence of macrovascular angiopath in patients with Type II diabetes mellitus. Plasma total homocysteine was determined by a HPLC-fluorescence detection method in a total of 238 subjects, 127 diabetic patients and 111 control. Dietary information including folate intake was assessed by a 24-hour recall in a total 113 subjects, 70 diabetic patients and 43 control. Folate intake was significantly lower inn patients with diabetes mellitus than that in the control. The lowered folate intake in the diabetic patients was mainly due to reduced intakes of fruits and vegetables. The average plasma homocysteine level of patients with MA was 14.2$\mu$㏖/L, which was significantly higher than that of either the patients without MA(11.4$\mu$㏖/L) or the control(11.5$\mu$㏖/L). Twenty five percent of the diabetic patients were positively correlated with age (r=0.20), body weight (r=0.28), body mass index (r=0.28), body mass index (r=0.18), diastolic blood pressure (r=0.20), and total cholesterol (r=0.14). cigarette smokers had significantly higher levels of plasma homocysteine than the non-smokers. Further prospective studies are needed to investigate whether folate or other B vitamin supplementation could be beneficial for the prevention of hyperhomocysteinemia or macrovascular angiopathy in the diabetic patients.

  • This study was carrid out to examine a part of the mechanism for the etiology of diabetic complications. Thirty normal and forty streptozotocin(STZ)-induced diabetic rats were used as the animal models. Animals were sacrificed at the time points of 3 days, 1, 2, 4 and 6 weeks after STZ-injection and time course in body weight and organ weight, the levels of blood glucose, plasma lipid patterns, and atherogenic index were measured during 6 weeks. The STZ-diabetic animals showed 63% survival rate and fsting blood glucose levels of the diabetic animals measured in the range of 230-410mg/dL during the experimental period. The body weigh of diabetic animals decreased significantly throughout the experimental period and the relative weights of organs to body weight were significantly higher than the normal control ones. The enlargement of the kidney in the diabetic animals was especially remarkable. Plasma triglyceride concentration in diabetic rats substancially increased from the first week of onset of diabetes mellitus and maintained higher levels than the control ones throughout the whole experimental period. The plasma total cholesterol level and atherogenic index in the diabetic rats were significantly higher than the normal ones from the third day after STZ injection and showed a gradual increase with the duration of the disease. Throughout the experiment, the diabetic rats consistently showed a slightly lower HDL-cholesterol level compared to the normal animals. From the results of this study, it appears that the significant changes in blood lipid pattern in STZ-diabetic animals start from the first week after STZ injection.

  • Four out of 15 dogs were successfully induced diabetes mellitus with intravenous iqiection of 30 mg of streptozotgin and 50 mg of alloxan monohydrate per kilogram body weight and maintained more than 9 weeks without iqiection of insulin or oral hypoglycemic sgent Histopathologicallyi these four dogs have typical diabetic lesions such as degeneration and vacuolation of pancreatic islet cells, and fatty change of liver at necropsy in the end of study. Serum glucose level increased dramatically at 24 hours post-injection but serum fructosamine level increased gradually and reached plateau at 31-41 days post-injection of streptozotocin and alloxan. Serum fructosamine concert%lion correlated very well with serum glucose concentration of preceding 4-7 weeks in experimentally induced diabetic dogs. Our data suggest that serum fructosamine reflects mean glucose concentration of preceding 4-7 weeks in experimentally induced diabetic dogs.

  • Objectives : The Herb-combined Remedy(HCR) for diabetes mellitus is known as an anti-hyperglycaemic agent. But its exact mechanisms are unclear. The present study was carried out to investigate its anti-hyperglycaemic and anti-oxidative effects in STZ-induced diabetic rats. Methods : Experimental diabetes was induced by injection of STZ(80mg/kg) to ratsvia the peritoneum. The experimental animals were divided into 4 groups : normal group, control group(STZ-induced diabetic rats with no treatment), HCR group(STZ-induced diabetic rats with HCR treatment), MF group(STZ-induced diabetic rats with Metformin treatment). The effects of HCR on STZ-induced diabetes was observed by measuring fasting blood glucose, changes of body weight, food uptake, and water uptake glucose levels in the normal state decline rates in blood glucose levels DPPH free-radical scavenging activity superoxide dismutase in RBC lysate catalase activity in RBC lysate and glutathione reductase activity in RBC lysate. Results : Treatment with HCR regulated blood glucose levels. Treatment with HCR also prevented weight loss in STZ-induced diabetic rats. In addition, oral glucose tolerance decreased following treatment with HCR. Direct anti-oxidative effects on DPPH free-radical scavenging were not observed, but treatment with HCR elevated SOD levels in blood cell lysates from STZ-induced diabetic rats. In addition, the HCR-treatment group showed an elevated tendency to glutathione reductase activity. Conclusions : These results demonstrate that HCR has anti-hyperglycaemic and anti-oxidative effects in STZ-induced diabetic rats.

  • This study investigated the in vivo insulin function of Polygonatum odoratum in normal and diabetic male Sprague-Dawley rats. Diabetes mellitus was induced by an i.p. injection of streptozotocin. Normal and diabetic rats were assigned to the diet groups of the control basal diet and Polygonatum odoratum diet. The animals were fed the diet and water ad libitum for 15 days. Initial and final body weights, total food intake and serum glucose and insulin levels were measured. An insulin suppression test was performed to elucidate the insulin function in the peripheral tissues. The results showed that the final serum glucose levels significantly decreased in the diabetic rats on the Polygonatum odoratum diet compared with the diabetic rats on the control diet. The final serum insulin levels were increased in the diabetic rats on the Polygonatum odoratum diet compared with the diabetic rats on the control diet. The in vivo function of the insulin increased in the diabetic rats on the Polygonatum odoratum compared with the diabetic rats on the control diet. These data indicate that Polygonatum odoratum may be beneficial in improving the in vivo insulin function in streptozotocin-induced diabetic rats.

  • The antidiabetic effects of Rosa rugosa Radix were investigated in streptozotocine-induced diabetic rats. Research methods and procedure: In the present study, effects of oral administration of Rosa rugosa Radix extract(100, 250, and 500 mg/kg body wt.) for 28 days on the level of serum glucose, total cholosterol, triglycerides, cereatinine, aspartate amino transferase(AST) and alanine amino transferase(ALT) in normal and streotozotocine-induced diabetic rats were evaluated. Oral administrations of the Rosa rugosa Radix extract significantly decreased serum glucose, total cholesterol, triglyceride, AST, and ALT levels, while increased serum insulin and HDL-C in diabetic rats(p<0.05). The hypoglycemic effect of the Rosa rugosa Radix extract was more effective than normal group. It is concluded that the Rosa rugosa Radix must be considered as excellent candidate for future studies on diabetes mellitus.
