  • Acer tegmentosum Max which is one of the specialized wildness medicinal herbs in gangwon province, has been widely used for hepatitis, liver cirrhosis, hepatic cancer, leukemia, diabetes mellitus, renal necrosis and edema, etc. In this study, the antioxidative and hepatoprotective effects of in vitro and in vivo were investigated in order to evaluate the possibility as hepatoprotective agents. Oral administration of methanol and butanol extact of Acer tegmentosum Max to d-galactosamine (D-GaIN) induced experimental liver injured rats was significantly reduced activities of marker enzymes(AST, ALT) and LDH activity in serum. Salidroside(Sal) isolated from the BuOH extract of Acer termentosum Max potenty showed the scavenzing effect on DPPH and inhibitory effect on lipid peroxidation. And significantly decrcease of MDA level in liver and activities of SOD GSH-Px and catalase were significantly improved by the treatment of Sal. Results of this study revealed that Sal could afford a significant protection in the alleviation of D-GaIN-induced hepatocellular injury.

  • The Hypoglycemic effect of exo-polymers (EPs) produced from submerged mycelial cultures of five types of mushrooms on streptozotocin (STZ)-induced diabetic rats were investigated in this study. The five experimental groups were fed with EPs (50 mg/kg body weight) for 7 days. Significant reduction in plasma glucose, total cholesterol (TC), and triglyceride (TG) levels were observed in rats fed with Lentinus edodes and Cordyceps militaris EPs. Plasma glucose and TC were also reduced by administration of Phellinus linteus EPs, but the TG level was not changed significantly. The EPs of three mushroom species also demonstrated a marked reduction in the level of plasma glutamate-pyruvate transminase (GPT). The result proves the hypoglycemic activity of EPs of three fungal group in STZ-induced diabetic rats and indicates their potential in the control of diabetes mellitus.

  • This paper aims to probe the effect of Rosa rugosa, Thunbergii which streptozotocin induced hyperglycemic rats was examined by glucose contents, body weight, kidney weight and histological observation. The results obtained were as follows: 1. The glucose level is decreased in the adminstered group of the Rosa rugosa compared with control group. These effects are in order named root group, stem group and leaf group group. BUN is increased fold of 1.52 in the control group compared with normal group, but the administered group of Rosa rugosa are decreased., in order named leaf group, root group and stem group. 2. The kidney hypertrophy to body weight is the higest in the control group compared with the other group in rats, and glucose contents are in order named stem group, leaf group and root group. 3. The loss of body weight is the highest in the control group, and the loss is in order named stem group, leaf group and root group in rats. 4. In histological observations, pancreatic pancreatic islets of control group shows disrupted or condensed nuclei, and the intercellular space between acini are enlarged. In the experimental group, histological damages of the acini and pancreatic islet are recovered compared with control group. Thes results suggest that the extracts of Rosa rugosa are effected to diabetes mellitus, root extract correlated with the function of kidney, and leaf extract is decreased plasma glucose.

  • Objective : To analyze the clinical characteristics of obese infertile women. Material and Method: Height, weight, body mass index, menstrual pattern, glucose, insulin, glucose/insulin ratio, dehydroepiandrosterone sulfate (DHEA-S), testosterone, free testosterone and plasminogen activator inhibitor (PAI-1) of 15 obese infertile women were tested. Results: Of 15 obese infertile women, the number of diabetes mellitus, hyperinsulinemia, and insulin resistance was 2 (13%), 2 (13%), 2 (13%), respectively. The incidence of increased DHEA-S, testosterone, and free testosterone was 7 (47%), 1 (7%), 6 (40%), respectively. Notably, all patients showed increased PAI-1. Conclusions: Obesity is associated with infertility as well as many kinds of health problems. Obesity is closely related to insulin resistance and it also causes hyperandrogenism. Increased PAI-1 is one of the important causes of thrombophilia. Consequently, in the workup of obese infertile patient, many aspects of health problems should be considered.

  • Twenty five cooking recipe with yam (Dioscorea japonica Thunb) have been developed and their hypoglycemic effects on diabetic patients were investigated. The results of the sensory evaluations revealed that the tested recipe were in good scores (overall acceptability scores 3.30-4.33) except Chojuli. The 10-panel members indicated that the yam cookings were more acceptable when they were cooked with other vegetables. Twenty seven diabetic patients were entered in a general hospital during the 2-month experimental period and they were allowed to consume the diet with yam cooking dish, 75 g of yam a day. The fasting blood glucose and 2-hour postprandial blood glucose levels were determined. The diabetic patients who consumed yam showed the lower blood glucose levels than those patients who were controlled with the hospital diet only. The hypoglycemic effects of the yam were more evident in the patients who were injected with insulin. The constant lowering effects of blood glucose levels were observed in the normal subjects who had taken the yam cookery, leading to that one subject who started with a low blood glucose level must stop the yam consumption after 10 days.

  • This study was designed to examine the effects of fractions of ethanol extract of Benincasa hispida (wax gourd) on hepatic antioxidative status in streptozotocin (STZ) induced diabetic rats. Sprague-Dawley rats were induced diabetes mellitus by STZ injection (45 mg/kg) into the tail vein and were divided into 5 groups: normal, STZ-control, three experimental diabetic groups. Fractions of ethanol extract of Benincasa hispida were administered orally into the diabetic rats for 14 days. Hepatic glutathione peroxidase (GSH-px) activity (determined with H$_2$O$_2$ as substrate) was increased in the groups supplemented with chloroform (CHCl$_3$) and butanol (BuOH) fractions. Glutathione peroxidase (GR) activity in the liver cytosol of H$_2$O fraction groups was significantly lower than that of STZ-control group. The H$_{2}$O fraction supplemented group has been shown the notably decrease in the hepatic superoxide dismutase (SOD) activity. The hepatic cytosol catalase (CAT) activity was significant decreased by the supplementation with BuOH fraction. It was found from the results that the supplementation of BuOH and H$_2$O fractions of Benincasa hispida extract could be beneficial for the diabetic complications and damages from the lipid peroxidation.

  • The studies have been designed to evaluate the effect of wound healing of pulsed ultrasound and chitosan application in diabetic incisive wound of rats. Mild diabetes mellitus was induced in rat used 30 mg/kg streptozotocin. Full thickness skin incision was made on the backs of Sprague-Dawley rats. We used 72 Sprague-Dawley rats which were divided into 4 groups; the subjects were divided into group of 6 rats each 3, 6, and 15 days. The results were summarized as follows; The rate of wound length of pulsed ultrasound with chitosan application groups more decreased than only pulsed ultrasound treatment group. The density of inflammatory cells in the experimental groups was more significantly decreased than diabetic control group(p<0.05). Historically, in the ultrasound with chitosan application groups, reepithelized epithelium was thicker and the collagen fiber were organized in a liner manner and connective tissue was matured faster those of the diabetic control group(p<0.05). From the conclusions above, in this study application of pulsed ultrasound and chitosan can be an effective way of promotion of wound healing in diabetic model.

  • Objective: The aim of the present study was to evaluate the predictive capability of fasting-state measurements of glucose and insulin levels alone for abnormal glucose tolerance in women with polycystic ovary syndrome (PCOS). Methods: In total, 153 Korean women with PCOS were included in this study. The correlations between the 2-hour postload glucose (2-hr PG) level during the 75-g oral glucose tolerance test (OGTT) and other parameters were evaluated using Pearson correlation coefficients and linear regression analysis. The predictive accuracy of fasting glucose and insulin levels and other fasting-state indices for assessing insulin sensitivity derived from glucose and insulin levels for abnormal glucose tolerance was evaluated using receiver operating characteristic (ROC) curve analysis. Results: Significant correlations were observed between the 2-hr PG level and most fasting-state parameters in women with PCOS. However, the area under the ROC curve values for each fasting-state parameter for predicting abnormal glucose tolerance were all between 0.5 and 0.7 in the study participants, which falls into the "less accurate" category for prediction. Conclusion: Fasting-state measurements of glucose and insulin alone are not enough to predict abnormal glucose tolerance in women with PCOS. A standard OGTT is needed to screen for impaired glucose tolerance and type 2 diabetes mellitus in women with PCOS.
