The edible seaweedSargassum polycystum(SP) is traditionally used against several human diseases. This investigation evaluated the effects of two dietary doses of SP ethanolic and aqueous extracts on the pancreatic, hepatic, and renal morphology of type 2 diabetic rats (T2DM). T2DM was induced by feeding rats on high calorie diet followed by a low dose streptozotocin. Changes in the diabetic rat organs in SP treated groups with different doses of extracts were compared with normal rats, diabetic control rats, and metformin treated rats. After 22 days of treatment, the pathological lesions of the livers and kidneys in the diabetic rats were quantitatively and qualitatively alleviated (P<0.05) by both the SP extracts at 150 mg/kg body weight and by metformin. All the treated diabetic groups revealed marked improvement in the histopathology of the pancreas compared with the control diabetic group. Oral administration of 300 mg/kg body weight of aqueous and ethanolic extracts of SP and metformin revealed pancreas protective or restorative effects. The seaweed extracts at 150 mg/kg body weight reduced the liver and kidney damages in the diabetic rats and may exert tissue repair or restoration of the pancreatic islets in experimentally induced diabetes to produce the beneficial homeostatic effects.

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.

AMP-activated protein kinase (AMPK) and c-AMP-response element binding protein (CREB) are found to be important proteins in metabolic system. AMPK has become the focus as a novel therapeutic target for the treatment of metabolic syndromes. Oyster mushroom is traditionally used as remedy of diabetes and hypertension. The present study aims to observe the stimulation of AMPK and CREB in streptozotocin-induced diabetic model rats through Oyster mushroom administration. Long Evan’s rats were used to create type 2 model diabetic rats through intraperitoneal injection of streptozotocin at 90mg/kg body weight of 48hr old pups. Rats were divided into three groups: diabetic control rats, glibenclamide treated diabetic rats (positive control) and mushroom treated diabetic rats (experimental group). Mushroom was administered orally at a dose of 1.25g/kg body weight in semisolid forms. After five weeks rats were sacrificed, serum and tissues were collected for future analysis. Glucose was measured using glucose-oxidase method, lipid profile by enzymaticcolorimetric method. Proteins from different tissues were extracted using RIPA cell lysis buffer, AMPK and CREB were identified using western blot and immuno-precipitation techniques. A significant decreased of fasting glucose was found after 35 days of experiment when it compared with control diabetic rats (M ± SD, mmol/l, Diabetic control group: 8.0±1.1; Mushroom treated diabetic group: 6.4±1.0; p=0.021). Glibenclamide treated diabetic rats have also shown decreased fasting glucose compared to control diabetic rats. In paired ‘t’ test analysis, it has been found that serum fasting glucose level was significantly decreased on 35th day compared the 0 day in both mushroom treated group (p=0.027) and in glibenclamide treated group (p=0.005). Serum TG level was decreased on 35th day compared to 0day in mushroom treated diabetic model rats only (M±SD, mg/dl, 0 day: 84±13; 35th day: 61±6, p=0.002). No significant changes of cholesterol, HDL and LDL were noticed in the experimental groups following treatment with mushroom. Western blot analyses have shown increased band intensity of AMPK and p-CREB in mushroom treated diabetic model rats. Therefore, it can be concluded that Anti-hyperglycemic property of Oyster mushroom could be explained through increased expression of AMPK and activation of CREB.Bangladesh Journal of Medical Science Vol.17(4) 2018 p.661-668

The study was designed to evaluate the glucose and cholesterol lowering effect of the aqueous extract of Centella asiatica leaf using the alloxan-induced diabetic rats and compared the activity with diabetic control and antidiabetic drug (Glibenclamide). Leaf extract (50 mg/kg) of C. asiatica and Glibenclamide were administered to normal and experimental diabetic rats for the duration of 10 days. In the alloxan-induced diabetic rat model, C. asiatica extract (50 mg/kg) significantly (p < 0.05) lowered the fasting blood glucose level as well as the total cholesterol level. Serum insulin levels were not stimulated in the animals treated with the extract. In addition, changes in body weight, serum lipid profiles and liver glycogen levels assessed in the extract treated diabetic rats were compared with diabetic control and normal animals. Significant results (p < 0.05) were observed in the estimated parameters. Surprisingly, body weight was increased significantly (p < 0.05) in the C. asiatica treated diabetic group. Phytochemical screening showed the presence of alkaloids, flavonoids, glycosides, steroids and tannins in significant amountsJahangirnagar University J. Biol. Sci. 4(1): 51-59, 2015 (June)

Diabetes mellitus prevalence has rapidly increased globally. Food contains high resistant starch (RS) may be used as a functional food to prevent and control diabetes mellitus. Resistant starch is high in raw bananas and its products such as flour. The study aimed to evaluate effects of Kepok banana flour on blood glucose and physical performance, especially body weight and feed intake in type 2 diabetic rats induced by nicotinamide (NA) and streptozotocin (STZ). Eight-week-old male Wistar rats weighed 150-200 g were randomly divided into nondiabetic and diabetic groups. Nondiabetic group (n=7 rats) was normal control (NC) and fed with standard diet AIN-93M (American Institute of Nutrition Rodent Diets 1993 for adult maintenance), while diabetic groups (n=7 rats each group) consisted of diabetic control (DC) which fed with standard diet and 3 diabetic treatment groups (T1-T3) which fed with AIN-93M containing kepok banana flour with 4%, 8% and 12% of RS respectively for 14 days. After 14 days, mean fasting blood glucose in group T1, T2 and T3 have lower blood glucose than DC significantly (p<0.05) with the highest decrease of blood glucose was on group T3. Mean of body weight in group T1, T2, T3, and NC gained significantly compared to DC group (p<0.05). Feed intake in group T1, T2, T3, and NC were less than DC significantly (p<0.05). Administration of kepok banana flour with 4%, 8% and 12% of RS is able to decrease glucose level, to restore body weight loss and to reduce feed intake in STZ-NA induced type 2 diabetic rats. Kepok banana flour can be proposed as an alternative diet in the management of type 2 diabetes.

Hyperglycemic Effect

Objective: To explore the anti-hyperglycemic effect of fruit extract of Terminalia catappa (Indian almond), a potential medicine from plant origin in a diabetic rat model.Methods: Streptozotocin-induced chronic diabetic rat model was utilized in the study. Three doses of test drug, hydro-alcoholic fruit extract of Terminalia catappa in 20 mg/kg, 30 mg/kg and 40 mg/kg and a standard anti-diabetic drug, glibenclamide (10 mg/kg) was used. The study had a total of nine groups with eight animals in each group. Drugs were given orally every day for 12 w. Blood glucose, body weight and urine volume were measured weekly, glycosylated hemoglobin (HbA1c) was estimated at 12th week in all groups. Data for all parameters were analyzed using one-way ANOVA repeated measures followed by Mann-Whitney test.Results: Hydro-alcoholic fruit extract of T. catappa significantly decreased blood glucose, urine volume and increased body weight in a dose-dependent manner in diabetic rats. At 12th week, blood glucose level in control, diabetic control, glibenclamide, T. catappa (40 mg/kg) group was 96.25±2.05 mg/dl, 599.75±0.25 mg/dl, 248.25±11.45 mg/dl, 115.00±3.78 mg/dl respectively. Effect of T. catappa in 30 mg/kg and 40 mg/kg dose was significantly more than glibenclamide. At 12th week, HbA1c level in control, diabetic control, glibenclamide, T. catappa (40 mg/kg) was 2.94±0.33 mmol/l, 4.94±0.49 mmol/l, 3.61±0.28 mmol/l, 3.21±0.27 mmol/l. Treatment with T. catappa 30 mg/kg, 40 mg/kg and glibenclamide brought back the level of HbA1c to normal levels. The addition of glibenclamide to T. catappa (40 mg/kg) did not produce any additional effect on blood glucose and HbA1c levels compared to the effect of T. catappa (40 mg/kg) in diabetic rats.Conclusion: Terminalia catappa fruit extract exhibited a significant anti-hyperglycemic effect in diabetic rats and has a great potential to be used in diabetes.

Antidiabetic Effects

This study was initiated to determine the possible antidiabetic effects of total flavonoids of Litsea Coreana leve (TFLC), an alcohol extract from the dried leaves of Litsea Coreana leve, on type 2 diabetic rats. Male Sprague-Dawley rats ( n = 40, 160–180 g) were divided into two groups and fed with normal chow diet (Normal Control group) or high-fat diet (HFD) for a period of 4 weeks. After 4 weeks of dietary manipulation, the HFD-fed rats were injected with 30 mg/kg streptozocin (STZ) to induce diabetes 72 hours after STZ injection. These diabetic rats were randomly divided into 3 groups ( n = 10): Diabetic Control group, Diabetic + TFLC group and Diabetic + PIO group. Diabetic + TFLC group and Diabetic + PIO group were orally administered with 400 mg/kg TFLC or 10 mg/kg pioglitazone (all suspended in 0.5% CMC-Na) respectively for 6 weeks. All rats were examined for body weight, serum and hepatic biochemical indices, content of malondialdehyde (MDA), activities of superoxide dismutase (SOD) and pathological changes in liver and pancreas, as well as protein tyrosine phosphatase 1B (PTP1B) expression in liver. The diabetic rats became obese, insulin resistant, hyperglycemic and hyperlipidemic. Treatment with TFLC showed a significant increase in insulin sensitivity, serum HDL-C level and SOD activities, meanwhile marked decrease in body weight, serum FFA, TC, TG, LDL-C, CRP, MDA content. TFLC also attenuated pathologic alterations in liver and pancreatic islet. Furthermore, TFLC was found to decrease the expression of PTP1B in diabetic rat liver. These results suggested that TFLC could ameliorate hyperglycemia, hyperlipoidemia, inflammation and oxidation stress, as well as insulin resistance of type 2 diabetic rats.
