<p>Chronic hyperglycemia is one of the signs of human type-2 diabetes mellitus due to insulin resistance and depletion. This study aimed to evaluate hexane, ethanolic, and aqueous leaf extracts of Urena lobata as antihyperglycemic agent. Design of this study was a post-test only control group using 25 male Sprague-Dawley rats divided into 5 groups. High fructose diet (HFD) ad libitum and single dose of intraperitoneal streptozocin (STZ) (25 mg/kgBW) were administered to induce diabetes in rats. Three groups of the diabetic rats orally received 500 mg/kgBW of only a type of leaf extract of U. lobata for 4 weeks. Insulin serum levels were measured using enzyme-linked immunosorbent assay (ELISA) method. Size, shape, and density of the islet cells were observed by light microscope. Blood glucose level and the area under curve (AUC) of serial oral glucose tolerance test (OGTT) were measured. The U. lobata leaf extracts of three types of solvent all increased serum insulin level and improved β cells condition, also decreased the AUC of the OGTT series in diabetic rats. Values were compared with untreated diabetic rats (p&lt;0,05). The aqueous leaf extract of U. lobata was the best in increasing insulin serum level, recovering islet cells condition, and correcting blood glucose level. The hexane extract showed poor results when compared to the other soluble agents.</p>

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.

Diabetes is a metabolic disease and plant derived products are used to combat this deadly disease. Plant is a diverse source of numerous therapeutic compounds which can be used to ameliorate diabetes. Leaves of Coccinia grandis (L.) (Family: Cucurbitaceae) is one of the leafy vegetable that is used for this purpose traditionally. It has been used against diabetes for a very long time. Our aims were to identify the hypoglycemic effect of extract of leaves of Coccinia grandis as well as to determine its safety profile so that we could use the plant material to improve the diabetic condition. Diabetes was induced in rats by intraperitoneal injection of alloxan at a dose of 150 mg/Kg bodyweight and ethanolic extract of leaves of Coccinia grandis was fed to the rats at a dose of 750 mg/kg. We measured blood glucose level, and safety profile by measuring SGOT, SGPT and creatinine level on diabetic and non-diabetic rats before and after administration of the extract. After measuring blood glucose level, it was found that the hypoglycemic efficacy was comparable to that of metformin (p> 0.05) which was given at a dose of 500 mg/kg. Safety profile were investigated by checking SGOT, SGPT and creatinine level. It was seen that both metformin and leaf extract of Coccinia grandis improved the pathological condition induced by diabetes. Furthermore, in healthy individual rats both metformin and leaf extract of Coccinia grandis did not significantly alter the normal physiological state. It might, therefore, be inferred that the extract of leaves of Coccinia grandis could be used as a good alternative therapy to treat diabetes.

Finger millet is a food crop with energy value, phytochemical constituents, and minerals, hence its use as whole flour for traditional food preparation among traditional people. The study was designed to determine the glycaemic index and blood glucose level in albino rats, and the antimicrobial potential of processed finger millets. Finger millets were processed by fermentation and roasting, and methanolic extracts obtained used to test antimicrobial activity. Albino rats (18) divided into three groups were fed fermented, roasted, and unprocessed millet (control), and glycaemic index and blood glucose level determined. Another 25 rat were treated into 5 groups of diabetic rats without treatment, diabetic rats treated daily with Metformin, diabetic rats fed 20% millet, diabetic rats fed 40% millet, and untreated group (control). At 100% concentration, roasted and fermented millet obtained inhibition of 15mm and 14mm against Salmonella typhi, while the control drug 25mg/ml streptomycin had 17mm inhibition. While values obtained for the glycemic indexes were close though significantly different from each other (roasted - 36.83±1.23; fermented - 38.73±1.87), roasted millet brought about the highest reduction in blood glucose level 90.9 and 65.1mg/dl at 60 and 120min respectively compared with fermented millet with 125.1 and 100.2mg/dl respectively at the same time. Animals administered finger millet in Groups 3 and 4-showed regeneration of the islet cells. The millet had the capacity to bring about healing of necrotic cells while also restoring and maintaining glucose levels in blood of subjects.

Wungu leaf (Graptophyllum pictum (L.) Griff) is a plant thought to have potential use in alleviating symptoms of diabetes mellitus. The purpose of the present study was to evaluate the activity of wungu leaf extracts in decreasing blood glucose level of alloxan (200 mg/kg BW)-induced hyperglycemic mice. Extracts of wungu leaf were obtained by macerating with ethanol and then partitioning the extract with diethyl ether, ethyl acetate, and butanol. Each extract obtained was used to treat hyperglycemic mice for 28 days. The results showed that wungu leaf extracts have the ability to decrease the blood glucose level of hyperglycemic mice (dose 50 mg/kg BW). The ethyl acetate extract showed the highest activity, bringing about a decrease of blood glucose of 37.6 %. The wungu leaf extract has the potential to be developed as a source of anti-diabetic agents.

The purpose of this study is to investigate the effects of total methanol leaf-extract of Dialium guineense (Cesalpiniaceae) and its fractions on blood glucose in rat. The fractions of methanol extract were obtained by chromatography Sephadex LH 20 gel, numbered F1 to F5. Experiments were performed in normoglycemic, glucose tolerance test, and type 2 diabetic rats. The total methanol leaf-extract (300 mg/kg, per os), induced a significant increase of blood glucose level in normoglycemic rats (2.27±0.12 vs 0.94±0.03 g/L) (p<0.05, n=5). F1 and F2 fractions (100 mg/kg, per os) increased the blood glucose level. Glycaemia respectively varied from 0.90 ± 0.03 to 2. 28 ± 0.22 g/L and 0.91 ± 0.03 to 1.43 ± 0.04 g /L (p<0.05, n=5). However, F5 fraction (300 mg/kg, per os), induced hypoglycemia (0.61 ± 0.01 vs 0. 80 ± 0.03 g/L) (p<0.05, n=5). F5 fraction prevented the pic of hyperglycemia caused by glucose (4 g/kg, per os). In type 2 diabetic rats, the daily oral administration of F5 fraction (300 mg/kg) induced an anti-hyperglycemic effect (1.28 ± 0.15 vs 4.48 ± 0.08 g/L). Fractionation by gel permeation chromatography allowed to highlight the presence of compounds both hyper-and hypoglycemic in total methanol leaf-extract of D. guineense. The lack of hypoglycemic effect in normoglycemic rats of total methanol leaf-extract, could respectively be related to the presence of both hyper- and hypoglycemic compounds in F1 and F5 fractions, which induced opposite effects.

Abstract Background Diabetes, a global cause of mortality in developing countries is a chronic disorder affecting the metabolism of macromolecules and has been attributed to the defective production and action of insulin characterized by persistent hyperglycemic properties. This global disorder harms organs of the body such as the liver, kidney and spleen. Medicinal plants such as Hunteria umbellate have been shown to possess hypoglycemic, antioxidative and anti-diabetic properties owing to the high concentration of active phytochemical constituents like flavonoids and alkaloids. The present study seeks to evaluate the hypoglycemic activities of ethanolic seed extract of Hunteria umbellate on streptozotocin-induced diabetes rats. Methods Thirty (30) female experimental rats were randomly divided into five groups with six rats per group and were administered streptozotocin (STZ) and Hunteria umbellate as follows. Group 1 served as control and was given only distilled water, group 2 rats were administered 60 mg/kg STZ; Group 3 was administered 60 mg/kg STZ and 100 mg/kg metformin; group 4 rats were administered 60 mg/kg STZ and 800 mg/kg Hunteria umbellate, group 5 rats 60 mg/kg STZ and 400 mg/kg Hunteria umbellate. The fasting blood glucose level of each rat was measured before sacrifice. Rats were then sacrificed 24 h after the last dose of treatment. Results The results showed that Hunteria umbellate significantly reversed STZ-induced increase in fasting blood glucose and increase in body and organs weight of rats. Hunteria umbellate significantly reversed STZ-induced decrease in antioxidant enzyme in liver, kidney and spleen of rats. Hunteria umbellate significantly reversed STZ-induced increase in oxidative stress markers in liver, kidney and spleen of rats. Conclusion Collectively, our results provide convincing information that inhibition of oxidative stress and regulation of blood glucose level are major mechanisms through which Hunteria umbellate protects against streptozotocin-induced diabketes rats.

Background: Diabetes increases the risk of macrovascular complications and is often associated with angina in patient. Currently nicorandil, a potassium channel opener is being frequently used for the prevention and long-term treatment of angina pectoris. Glibenclamide exerts its antidiabetic action by closing the ATP sensitive potassium channels. Simultaneous use of nicorandil may antagonizes this action and may worsens the existing diabetes. To evaluate the pharmacodynamic interaction present study has been taken to study the effect of Nicorandil, a potassium channel opener on blood glucose level of alloxan induced diabetic rats and its pharmacodynamics interaction with Glibenclamide.Methods: Albino rats, weighing 150-200gm of male sex were used for the study. Diabetes was induced by injecting alloxan monohydrate 2% solution intra peritoneally in a dose of 150mg/kg body weight. Animal with Fasting Blood Sugar level between 250-300g/dl was selected for study and they were divided into 4 groups of 5 animals each. Group I- serving as control received 0.5ml normal saline orally for 28 days. Group II was given glibenclamide (0.5mg/kg body wt) for 28 days. Group III was treated orally with nicorandil (0.3mg/kg body wt) for 28 days. Group IV was given glibenclamide (0.5mg/kg) and nicorandil (0.3mg/kg) for 28 days. Fasting Blood Sugar level was recorded in all rats on 1st,3rd,7th,14th,21st and 28th day of the treatments.Results: results showed that glibenclamide significantly reduce blood sugar level (p <0.05) Wherase nicorandil showed rise in blood glucose level (p <0.05) While the combination (glibenclamide + nicorandil) showed rise in blood glucose (p <0.05) overall.Conclusions: Nicorandil worsen the existing diabetes and to be avoided or replaced with alternative drug in case of diabetes being treated with sulfonyl urease group of drugs.

Aims: To investigate the effect of food blends (plantain, soybean and ginger) on the blood glucose, lipid profile and haematological indices on streptozotocin induced diabetic rats. Methodology: A total of 35 rats of mean body weight 219.07 g separated into7 groups (5 per group) where induced by a single intraperitoneal (I.P) injection of streptozotocin (0.1 g dissolved in 5 ml of freshly prepared sodium citrate buffer 0.1 M, pH 4.5) at a dose of 40 mg/kg body weight after fasting for 12 hours and fed with flours/blends. The flours were produced from plant materials for different treatments/blends (blend A=100% unripe plantain, B=80% unripe plantain, 14% soybean, 6% ginger, C=70% unripe plantain, 26% soybean, 4% ginger, D= 60% unripe plantain, 38% soybean, 2% ginger, E= 50% unripe plantain, 50% soybean) and the phytochemicals and minerals content were determined. Blood glucose was determined at 5 days interval for 25 days. Diabetes was confirmed in rats with blood glucose concentrations >200 mg/dl. After 25 days rats were anaesthetized with chloroform vapour and blood samples collected by cardiac puncture for haematology and lipid profile determination. Results: The results showed that unripe plantain, soya beans and ginger in adequate proportion(C=70% unripe plantain, 26% soybean, 4% ginger or D= 60% unripe plantain, 38% soybean, 2% ginger) could help to reduce blood glucose, improve haematological parameters and lipid profile. Significant reduction was observed in the blood glucose level of rats fed blends C and D from 286 to 85 mg/dl and 307 to 90 mg/dl respectively at the end of experiment. These results also demonstrated that the inclusion of ginger at 6% causes rise in blood glucose level. Total cholesterol (TC) increased in all the blends. However, the lowest concentration of TC was observed in blends C and D. The highest packed cell volume (60%) and Haemoglobin (20 g/dl) level observed in rats fed blend C was significantly higher than the normal control fed conventional feeds. The increase in packed cell volume (PCV) (50%) and Hb (17 g/dl) in diabetic rats demonstrated that the formulated blend C was able to raise PCV and Hb above 50% and 17 g/dl (Normal control NC) respectively. Significant increase (P<0.05) in low density lipoprotein cholesterol (LDLc) was also observed in all the blends with blend C having the least (4.0 mg/dl) close to NC (2.0 mg/dl). Conclusion: From the results it is evident that blend C will manage and improve the health status of diabetic patients.
