  • BACKGROUND/OBJECTIVE: The blue honeysuckle berry (Lonicera caerulea var. edulis L.) is a small deciduous shrub belonging to the Caprifoliaceae family that is native to Russia, China, Japan, and Korea. The berry of this shrub is edible, sweet and juicy and is commonly known as the blue honeyberry (BHB). This study examined the anti-diabetic potential of BHB on high-fat-diet-induced mild diabetic mice. The hypoglycemic, and nephroprotective effects of the 12-week oral administration of blue honeyberry extract were analyzed. MATERIALS/METHODS: The hypoglycemic effects were based on the observed changes in insulin, blood glucose, and glycated hemoglobin (HbA1c). Furthermore, the changes in the weight of the pancreas, including its histopathology and immunohistochemical investigation were also performed. Moreover, the nephroprotective effects were analyzed by observing the changes in kidney weight, its histopathology, blood urea nitrogen (BUN), and serum creatinine levels. RESULTS: The results showed that the high-fat diet (HFD)-induced control mice showed a noticeable increase in blood glucose, insulin, HbA1c, BUN, and creatinine levels. Furthermore, growth was observed in lipid droplet deposition related to the degenerative lesions in the vacuolated renal tubules with the evident enlargement and hyperplasia of the pancreatic islets. In addition, in the endocrine pancreas, there was an increase in the insulin-and glucagon-producing cells, as well as in the insulin/glucagon cell ratios. On the other hand, compared to the HFD-treated mice group, all these diabetic and related complications were ameliorated significantly in a dose-dependent manner after 84 days of the continuous oral administration of BHBe at 400, 200 and 100 mg/kg, and a dramatic resettlement in the hepatic glucose-regulating enzyme activities was observed. CONCLUSIONS: By assessing the key parameters for T2DM, the present study showed that the BHBe could act as a potential herbal agent to cure diabetes (type II) and associated ailments in HFD-induced mice.

  • 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.

  • This study investigated the effect of Rehmanniae Radix preparata extract on the antioxidant enzymes of kidney and renal function in streptozotocin-induced diabetic rats. Male Sprague-Dawley rats were divided into three groups including normal control (NC), diabetic control (DC), and diabetic treatment with Rehmanniae Radix preparata (DRR). Over a 4-week study period, Rehmanniae Radix preparata aqueous extract was administered orally at 1124 mg/kg BW/day. The serum glucose level in the DRR group was significantly lower (P<0.05) than the DC group. The serum blood urea nitrogen in diabetic groups was significantly higher (P<0.001) than the NC group. The urinary total protein level in the DRR group was significantly lower (P<0.05) than the DC group. The renal xanthine oxidase activity in the DRR group was significantly lower (P<0.01) than the DC group. The renal catalase activity in the DC group was significantly lower (P<0.05) compared to the NC group and that was significantly higher (P<0.05) in the DRR group than the DC group. In conclusion, these results indicated that Rehmanniae Radix preparata can prevent or retard the development of diabetic nephropathy via its beneficial effects for correcting the hyperglycemia and favorable effects on antioxidant enzyme system.

  • Diabetes mellitus is a worldwide epidemic with high mortality. As concern over this disease rises, the number and value of research grants awarded by the National Research Foundation of Korea (NRF) have increased. Diabetes mellitus is classified into two groups. Type 1 diabetes requires insulin treatment, whereas type 2 diabetes, which is characterized by insulin resistance, can be treated using a variety of therapeutic approaches. Hyperglycemia is thought to be a primary factor in the onset of diabetes, although hyperlipidemia also plays a role. The major organs active in the regulation of blood glucose are the pancreas, liver, skeletal muscle, adipose tissue, intestine, and kidney. Diabetic complications are generally classified as macrovascular (e.g., stroke and heart disease) or microvascular (i.e., diabetic neuropathy, nephropathy, and retinopathy). Several animal models of diabetes have been used to develop oral therapeutic agents, including sulfonylureas, biguanides, thiazolidinediones, acarbose, and miglitol, for both type 1 and type 2 diseases. This review provides an overview of diabetes mellitus, describes oral therapeutic agents for diabetes and their targets, and discusses new developments in diabetic drug research.

  • The methanol extract of seeds of Swietenia macrophylla King. (MESM) was studied for its antidiabetic activity in streptozotocin induced diabetic rats. It was principally aimed to correlate the efficacious role of MESM on reduction of oxidative state associated with diabetes. The extract was found to be potent antidiabetic evidenced by significant reduction of blood glucose level in diabetic rats (47.96% reduction of blood glucose level, at 300 mg/kg, on day 10). It was found that, MESM at 300 mg/kg, significantly decreased TBARS (35.03 and 22.22%) whilst increased GSH (86.75 and 31.45%), SOD (93.05 and 45.88%) and CAT (56.99 and 68.46%) levels in liver and kidney respectively in diabetic rats.

  • Rhus verniciflua Stokes(RVS) has been widely used as a food and traditional herbal medicine in Korea. RVS has been reported that the extract from its wood and fruit has strong antioxidant activity and anticancer effect but there is little information on Lacca Sinica Exsiccata(LSE), the resin of RVS, as a medicinal use. The aim of this study was to evaluate the antidiabetic effect of ethanol-eluted extract of LSE on streptozotocin(STZ) - induced diabetic rats. Diabetes was induced in male Sprague-Dawley rats with STZ injection. Oral administration of LSE extract(50mg or 100mg/kg of body weight/day) was given to diabetic group. During 4 weeks of experiment, diabetic rats showed significant weight loss and decreasing feed efficiency ratios(FER) compared with normal rats, while the diabetic group orally fed with LSE extract showed a trend of decreasing weight loss and a significant increase of FER(p<0.05). In 4 weeks after induction of diabetes, diabetic rats showed an increase in weight of liver, kidney and heart, whereas the diabetic rats administered with LSE extract showed a reduction in the weight of heart. Blood glucose level was decreased in diabetic rats treated with LSE extract, but it was not statistically significant. Glutamic oxaloacetic transaminase, Glutamic pyruvate transaminase and total cholesterol levels were lower in the diabetic group treated with LSE extract than in untreated diabetic group, but not significant. These results present that LSE may partly have antidiabetic effect and may protect against the development of diabetic heart complications resulting from impaired glucose metabolism.

  • We have evaluated the effect of long term treatment of Enicostemma littorale (E. littorale) in type 2 diabetic patients taking pills of aqueous extract of E. littorale regularly as a complimentary medicine for at least 9 months. The effects of E. littorale on glycemic control, lipid profile, cardiac function and DNA damage in these patients were compared with those who had not been regular in taking E. littorale but regular in taking other conventional anti-diabetics. Our data suggest that, E. littorale can maintain normal blood glucose, serum insulin, serum triglycerides levels of type 2 diabetic patients if taken regularly. E. littorale also improves insulin sensitivity, and normalize disturbed lipogram and elevated creatinine levels, thereby produces beneficial effect in preventing cardiovascular complications and may preserve the kidney function. The finding that E. littorale also prevents DNA damage suggest a long term effect in diabetic patients. E. littorale thus can be considered as safe supplementary therapy for a long term and effective management of type 2 diabetic patients.
