Supported by many studies and botanical surveys, the potential role of medicinal plants as antidiabetic agents has dramatically raised. The present study was designed to investigate the hypoglycemic effect of A. biebersteinii Afan. ethanolic extract in both types of diabetes, using blood glucose and insulin levels as markers for its efficacy, morphological changes of pancreatic β-cell islets as a potential marker for a protective role, and high fat diet-streptozocin (HFD-STZ) induced diabetic rats and STZ-induced diabetic rats as diabetic models. Aerial part ethanolic extract was administered by oral gavage for 16 days at a dose of 400 mg/kg. Glibenclamide at a dose of 3 mg/kg, and metformin at a dose of 300 mg/kg were used as reference standards. A. biebersteinii Afan. reduced significantly fasting blood glucose (FBG) levels, improved oral glucose tolerance, tended to raise serum insulin levels, enhanced regeneration of β cells, and seemed to be more effective than the reference standards. It is assumed that A. biebersteinii Afan. increases utilization of glucose by tissues and/or enhances insulin release from remanent and/or regenerated β-cells. In conclusion, A. biebersteinii Afan. possesses potent antihyperglycemic activity and it may prove to be effective for the treatment of both types of diabetes.

AbstractObjectivesType 2 diabetes is a common metabolic disease and anxiety disorders are very common among diabetics. Buspirone is used in the treatment of anxiety, also having blood glucose-lowering effects. The aim of the study was to investigate the effects of buspirone on the glucose and lipid metabolism as well as vascular function in type 2 diabetic rats.MethodsA type 2-diabetic model was induced through a high-fat diet for eight weeks followed by the administration of low-dose streptozotocin (35 mg/kg, intraperitoneal) in rats. Buspirone was given at two different doses (1.5 mg/kg/d and 5 mg/kg/d) and combined with metformin (300 mg/kg/d). The fasting glucose and insulin levels, lipid profile were analyzed, and vascular response measured from the thoracic aorta was also evaluated.ResultsBoth doses of buspirone caused a significant improvement in fasting blood glucose levels. In particular, the buspirone treatment, combined with metformin, improved endothelial dysfunction and was found to be correlated with decreased nitrate/nitrite levels.ConclusionsBuspirone may be effective in the treatment of type 2 diabetes, either alone or in combination with other treatments, particularly in terms of endothelial dysfunction, inflammation and impaired blood glucose, and insulin levels.

Background: The anti-hyperglycemic potential of methanol stem bark extract of Anacardium occidentale (MSBEAO) was investigated using an alloxan-induced diabetic rat model. Alloxan administration induces the generation of free radicals which can affect antioxidant status resulting in the disruption of the β-cells of the pancreas. Therefore, this study examines the antioxidant potential of the plant extract and the ameliorating effect on the pancreas of alloxan-induced diabetic rats. Methods: Diabetes was induced by intraperitoneal injection of 150 mg/kg body weight of alloxan monohydrate. MSBEAO, at a concentration of 100 or 200 mg/kg b.w. was orally administered to alloxan-induced diabetic rats and normal rats. The hypoglycemic effect, oral glucose tolerance test, and biochemical assay of alloxan-induced diabetic rats were assayed using standard procedures. Results: Preliminary phytochemical screening of the extract revealed the presence of alkaloids, tannins, saponins, terpenoids, carbohydrates, and phenols at moderate concentrations. The lethality dose (LD50) of the plant extract was found to be equal to or less than 5000 mg/kg b.w. The hypoglycemic effect of the extract on the non-diabetic rats revealed a significant (p<0.05) decrease in the blood glucose concentration of animals administered with 1 g/kg b.w. of the extract, compared to normal control rats administered with normal saline. In the oral glucose tolerance test, the methanol extract exerted the highest response, similar to glibenclamide after 15 and 30 minutes of administration, compared to the control rats. The methanol extract yielded the highest blood glucose lowering effects after 9 days of treatment (p<0.05), compared to diabetic rats administered with normal saline and 0.3 mg/kg b.w. of glibenclamide. Administration of the extract at 200 mg/kg b.w. showed improved pancreas architecture and regeneration of the β-cells, compared with the pancreas of animals in the other groups. Conclusion: The results of this study suggest that MSBEAO is a potentially effective agent for the management of diabetes which might result from the antioxidant-generating capacity of the stem bark.

Some lactic acid bacteria (LAB) are observed to be potential probiotics with functional properties such as lowering fasting blood glucose (FBG), as a promising hyperglycemia management. This study investigated the ability and mechanism of Lactobacillus rhamnosus BSL and Lactobacillus rhamnosus R23 on lowering FBG in diabetic rats induced by streptozotocin (STZ). The rats were orally administered with L. rhamnosus BSL and L. rhamnosus R23 by giving 1 mL cell suspension (109 CFU/mL) daily for 30 days. The body weight (BW) was recorded once in three days, and FBG was recorded once in six days. An oral glucose tolerance test (OGTT) was measured 1 week after injection with STZ and before sacrifice. Fecal samples were collected on days 0, 15, and 30 for LAB population and identification, performed by PCR detecting 16S rRNA. Oral administration of L. rhamnosus BSL and L. rhamnosus R23 decreased FBG and improved glucose tolerance via downregulation of glucose-6-phosphatase (G6pc) expression by 0.57- and 0.60-fold change, respectively (P<0.05). The lipid profiles, BUN, creatinine, SGOT, and SGPT were significantly (P<0.05) different between normal and diabetic rats, but they were not significantly (P>0.05) different among diabetic rats. Both strains were effective in increasing fecal LAB population. Molecular identification of the isolated LAB from fecal sample indicated that they were able to survive and pass through the digestive tract. These results suggested that both strains have the ability to manage blood glucose level and become a promising agent to manage hyperglycemia and diabetes.

Introduction: The study was done at the aim to assess the functionality and viability of the β cells of the streptozotocin-induced diabetic rats model following repetitive dosage of administration of ethanolic extracts of Andrographis paniculata. Materials and Methods: The diabetic rats were treated with the extracts for fourteen days and at the dose given was 500 mg/kg twice daily. The assessments were made on fasting blood glucose, insulin, and immunohistochemical aspect of β cells before and after treatment. Results: The results showed that there was a significant reduction on fasting blood glucose levels in metformin, 95% and 50% ethanolic plant extracts-treated groups but on insulin level only 95% and 50% ethanolic extracts-treated groups gave a significant reduction (p<0.05). Immunohistochemical assessments revealed that all extract groups and metformin-treated were significantly increased in the population of β cells (p<0.01). Conclusion: This study revealed that the plant extracts showed an ability to promote the growth or rejuvenate the STZdestructed β cells and in turn lower the blood glucose level.

Abstract Background Diabetes mellitus is a serious complex multifactorial disorder that imposes huge health and economic burden on societies. Because the currently available medications have many drawbacks, it's important to look for alternative therapies. Medicinal plants utilized in folk medicine are ideal candidates. Therefore, this work assessed the antidiabetic action of n-butanol extract from the whole plant Atractylis flava Desf (BEAF). These ethnomedicinal properties of BEAF were scientifically validated using in vitro and in vivo assays. In vitro antidiabetic effect of the BEAF was conducted using α-Glucosidase and α-Amylase assays. While the antihyperglycemic activity was assessed using two rat models: Alloxan-induced diabetic rats and oral glucose challenged rats. Experimental diabetes was induced by a single intraperitoneal injection of alloxan at a dose of 150 mg/kg and animals with fasting blood glucose levels (BGL) > 200 mg/dL were considered diabetic. Glibenclamide (5 mg/kg) was used as a typical drug. Results The BEAF at all tested dose levels (100, 250, and 500 mg/kg) showed a significant decrease in blood glucose level in all the two animal models. Besides, the plant extract exhibited a potent inhibitory effect on α-Amylase and α-Glucosidase activity at a concentration of 1000 µg/mL with 76.17% and 89.37%, respectively. Conclusion BEAF exerts in vitro and in vivo antidiabetic effects, these results suggest that the plant extract can be a therapeutic resource in the treatment of diabetes and hyperlipidemia.

Background:: Metformin is a biguanide that exhibits an antidiabetic, anticarcinogenic and anti-inflammatory properties. Despite well-known pancreatic protective effects, metformin's influence on pancreatic islet β-cell is yet considerably unknown. Protecting the functional insulin-producing β-cells in the pancreas is a key therapeutic challenge in patients with type 1 (T1DM) or type 2 diabetes mellitus (T2DM). Objective:: Current study aimed to analyze the protective effects of metformin on streptozocin-induced diabetic rats in T1DM in hepatic tissues. Methods: : In the present study, male wistar rats (n=24) were randomly assigned into 2 groups (n=12 for each control and test) by which metformin (100 mg/kg/day) were given for 7 weeks. Afterwards, diabetes was induced by streptozocin (STZ) at a single dose of (150 mg/kg). Blood glucose was daily examined before and after STZ induction. The animals were euthanized by cervical dislocation 5 days after streptozocin injection, after which liver and pancreas were harvested from each rat. Results: : The biochemical analyses revealed that metformin resulted in significantly reduced plasma glucose levels and higher pancreatic insulin levels in the test group. Using a restrictive cut-off of at least 2-FC and an adjusted p-value (qvalue) of ≤0.05 a sum of 747 genes for the metformin group were shown to be differentially regulated compared to controls (320 Down and 427 Up), by which they were obtained from the liver. Furthermore, evidence is attained that metformin may hinder the loss of critical β-cells by reducing inflammatory and apoptosis signaling, promoting fatty acid β-oxidation and inducing metabolism. Conclusion: : Collectively, this study has demonstrated a decrease in blood glucose levels and a rise in insulin-levels and thus a consequent prophylactic effects in metformin-given STZ-induced diabetic rats.

Combination therapy is considered as a new and effective therapeutic strategy for control of hyperglycemia. The present study aimed to determine the hypoglycemic effect of Afghan Hibiscus sabdariffa L. and Carum Carvi L. hydro-alcoholic extracts either alone or in combination on diabetic rats. Streptozotocin-induced diabetic rats were administered intraperitoneally with hydro-alcoholic extracts of H. sabdariffa (75, 150 and 300 mg/kg), C. carvi (150, 300 and 500 mg/kg) and their combinations for 21 days. The Fasting blood glucose and body weight of rats were determined on 0, 7, 14 and 21st days. The results showed a significant (P<0.0001) hypoglycemic effect of H. sabdariffa extract (75, 150 and 300 mg/kg) on 7, 14 and 21th days, C. carvi extract (500 mg/kg), and their effective doses combination (75:25), especially on 7th day. Only 75 mg/kg of H. sabdariffa had positive effect on body weight loss of diabetic rats (P<0.05). One can conclude that Afghan H. sabdariffa and C. carvi hydro-alcoholic extracts and their combination have a hypoglycemic effect. However, their combinations do not have any synergic effects, so the hypoglycemic effect of H. sabdariffa was much greater and even normalized the blood glucose level.

The association of liver and muscle glycogen deposits with serum insulin levels, β-cells pancreas, and fasting blood glucose (FBG) of streptozotocin (STZ)-induced hyperglycemic rats receiving Torbangun leaves extract (TE) investigated. The intervention performed on 25 8-week-old Sprague-Dawley rats divided into four groups. Seven rats separated as a normal group (N), and other rats injected with streptozotocin (STZ). Confirmation of hyperglycemic was characterized by fasting blood glucose >126 mg/dl. Treatment group which is NG (hyperglycemic rats); N (normal rats); H-IM (62.5 mg/kg BW metformin); and H-IT (620 mg/kg BW TE) for 14 days. This study revealed that TE significantly decreased FBG levels, increased insulin production, and the amount of liver glycogen deposits (a=0.01). However, the intervention did not significantly increase the amount of muscle glycogen deposits. TE administration improves β-cells, increases the liver and muscle glycogen deposits. TE was shown to have antihyperglycemic activity by improving the β-cell, increasing blood serum insulin levels, decreasing blood glucose levels, and increasing the liver glycogen deposits.
