The methanol extract of Aralia elata root bark was found to decrease the blood glucose level in normal and alloxan-treated rats. The fractionation process confirmed positive activity in ethylacetate fraction. It is suggested that this fraction may show potent antihyperglyceimic activity through stimulation of insulin secretion.

식용버섯 자실체를 이용하여 새로운 식후 혈당상승억제물질을 개발하기 위하여 노랑느타리버섯 자실체에 함유되어있는 ${\alpha}$-glucosidase 저해물질을 증류수로 추출하여 식후 혈당 상승억제효과를 조사하였다. ${\alpha}$-Glucosidase 저해물질을 함유한 노랑느타리버섯 물추출물은 streptozotocin으로 당뇨를 유발시킨 당뇨 쥐에서 장기 30 mg/kg, 150 mg/kg 경구투여(2일)와 단기 500 mg/kg, 1,000 mg/kg 경구투여(120분)시 모두, 농도 의존적으로 식후 혈당상승억제 효과를 보였다.

Objectives : This study aims to estimate the oral antihyperglycemic medications adherence among ambulatory care with adult type 2 diabetes patients and to identify factors affecting the medication adherence in Korea. Methods : This study used the Korean National Health Insurance Database. Study population was 40,082 patients who were 20 years of age or older and first diagnosed with type 2 diabetes (ICD-10: E11) in 2004. The patients were followed up for two years in order to measure adherence with oral antihyperglycemic medications. The level of medication adherence was measured by the medication possession ratio (MPR). Results : The average MPR in the study population was 49.5%. The appropriate adherence rate (MPR$\geq$80%) was 29.4% and showed variation according to the characteristics of individual patients. Multiple logistic regression analysis revealed that the odds of appropriate adherence increased with female (OR:1.21, CI:1.14-1.27), older age, increasing ambulatory care visits, health insurance (OR:1.53, CI:1.33-1.76), decreasing ambulatory care providers, using a specialized general hospital as their main attending medical institution (OR:10.08, CI:8.96-11.33), having co-morbidity, using polytherapy (OR:1.07, CI:1.01-1.13). Conclusions : The medications adherence for patient with type 2 diabetes is low in Korea, and shows variation according to the characteristics of patients. For proper management of diabetes, health care policy is expected to be enacted to improve medications adherence continuously. In particular, more intensive management is needed for patients with low medications adherence. Also, health care policy makers need to develop the program to induce health care utilization by a patient to be more concentrated with the same provider.

The present study was carried out to investigate the antihyperglycemic, antihyperlipidemic and antioxidant effect of chloroform and methanol extract of whole plant of Ichnocarpus frutescens (CEIF and MEIF) in streptozotocin (STZ)-induced diabetic rats. Administration of CEIF and MEIF orally at the dose of 200 mg/kg and 400 mg/kg body weight resulted in significant (P<0.01) reduction in blood glucose levels. The body weights were significantly (P<0.001) reduced in STZ-induced diabetic rats when compared to normal rats while the extracts significantly (P<0.01) prevented the decrease in body weight in the CEIF and MEIF treated rats. The study was further undertaken to evaluate the antioxidant and antihyperlipidemic potential of CEIF and MEIF in STZ-induced diabetic rats. The increased levels of lipid peroxidation in the liver tissues of diabetic rats were significantly reverted back to normal levels and a significant increase in activity of antioxidant enzymes such as superoxide dismutase, catalase and the level of reduced glutathione in the liver of diabetic rats after the treatment with CEIF and MEIF was noticed. These results clearly indicate that CEIF and MEIF exhibit significant antihyperglycemic, antihyperlipidemic and in vivo antioxidant activity in STZ-induced diabetic rats and the results were found to be in a dose dependent manner.

The hypoglycemic and antihyperglycemic activity of methanolic extract of Pluchea indica Less. (Asteraceae) (MEPI) leaves were studied in normal rats and in streptozotocin induced diabetic rats respectively. The blood glucose levels were measured at 1, 4, 8, 16 and 24 h intervals after the treatment. The MEPI leaves showed reduction in blood glucose level in normal (35.12% and 36.01 % for 200 and 400 mg/kg, p.o. respectively) and in steptozotocin induced diabetic rats (36.10% and 41.87% for 200 and 400 mg/kg respectively). A toxicity study has been performed for the extract, which revealed that the extract is safe to use even at the doses of 3.2 gm/kg of body weight orally.

The study was to evaluate the antihyperglycemic activity of Biophytum sensitivum (L.) DC in different extracts. Albino Wistar rats with alloxan hydrate induced diabetes were divided into 7 groups of 6 each. Both aqueous and methanolic extract of Biophytum sensitivum were prepared and given individually at different doses to different batches of rats (both normal and diabetic rats) after an overnight fast. Methanolic extract at the dose of 200 mg/kg body weight showed maximum blood glucose lowering effect in diabetic rats. The same dosages did not produce any hypoglycemic activity in normal rats. The antihyperglycemic activity of Biophytum sensitivum was compared with a standard drug Glibenclamide, an oral hypoglycemic agent. The above results suggest that maximum hypoglycemic effect was found only with a dose of up to 200 mg/kg b.w. of methanolic extract which is therefore the optimum dose for hypoglycemia and was used in all the experiments of the present study.

Alloxan administration in rats is used as a model for non-insulin dependent diabetes mellitus (NIDDM). NIDDM is a multifactorial disease, characterized by hyperglycemia and lipoprotein abnormalities. In this study, we evaluated the antihyperglycemic and antihyperlipidemic effects of fermented Rhynchosia nulubilis (FRN) through the regulation of glucose uptake in alloxan-induced rats. Fermented R. nulubilis was administered orally for 28 d at 500 mg/kg of body weight. Body weight and food intake were monitored every day. Biochemical parameters were quantified after 4 week. In the diabetic + FRN group, body weight increased significantly and blood glucose concentrations decreased when compared to those of the diabetic group. After 2 hr of administration, the oral glucose tolerance test (OGTT) indicated a significant reduction in the diabetic + FRN group compared to diabetic group. The diabetic + FRN group experienced a significant reduction in total cholesterol, triglycerides, low density lipoprotein, coronary risk factors, and malondialdehyde concentrations, with significantly increased high density lipoprotein compared to those of diabetic group. These results demonstrate that fermented R. nulubilis possesses potent antihyperglycemic and antihyperlipidemic activity in alloxan-induced diabetic rats.

An antihyperglycemic compound in a model of alloxan induced diabetic rats was isolated from the root bark of Aralia elata. The compound identified to be oleanolic acid $28-O-{\beta}-_D-glucopyranoside$ was active at a dose of 100 mg/kg p.o. in the rats. It also has increased the contents of liver glycogen which were lowered by injection of alloxan in the rats.
