Antidiabetic Effects

Diabetic complications occur as a result of increased reactive oxygen species (ROS) due to long term hyperglycaemia. Honey and ginger have been shown to exhibit antioxidant activity which can scavenge ROS. The main aim of this study was to evaluate the antioxidant and antidiabetic effects of gelam honey, ginger, and their combination. Sprague-Dawley rats were divided into 2 major groups which consisted of diabetic and nondiabetic rats. Diabetes was induced with streptozotocin intramuscularly (55 mg/kg body weight). Each group was further divided into 4 smaller groups according to the supplements administered: distilled water, honey (2 g/kg body weight), ginger (60 mg/kg body weight), and honey + ginger. Body weight and glucose levels were recorded weekly, while blood from the orbital sinus was obtained after 3 weeks of supplementation for the estimation of metabolic profile: glucose, triglyceride (TG), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), reduced glutathione (GSH): oxidized glutathione (GSSG), and malondialdehyde (MDA). The combination of gelam honey and ginger did not show hypoglycaemic potential; however, the combination treatment reduced significantly (P<0.05) SOD and CAT activities as well as MDA level, while GSH level and GSH/GSSG ratio were significantly elevated (P<0.05) in STZ-induced diabetic rats compared to diabetic control rats.

The aim of this study was to investigate if dietary administration of γ-aminobutyric acid (GABA)-producing Lactobacillus brevis DPC 6108 and pure GABA exert protective effects against the development of diabetes in streptozotocin (STZ)-induced diabetic Sprague Dawley rats. In a first experiment, healthy rats were divided in 3 groups (n=10/group) receiving placebo, 2.6 mg/kg body weight (bw) pure GABA or L. brevis DPC 6108 (~109microorganisms). In a second experiment, rats (n=15/group) were randomised to five groups and four of these received an injection of STZ to induce type 1 diabetes. Diabetic and non-diabetic controls received placebo [4% (w/v) yeast extract in dH2O], while the other three diabetic groups received one of the following dietary supplements: 2.6 mg/kg bw GABA (low GABA), 200 mg/kg bw GABA (high GABA) or ~109 L. brevis DPC 6108. L. brevis DPC 6108 supplementation was associated with increased serum insulin levels (P<0.05), but did not alter other metabolic markers in healthy rats. Diabetes induced by STZ injection decreased body weight (P<0.05), increased intestinal length (P<0.05) and stimulated water and food intake. Insulin was decreased (P<0.05), whereas glucose was increased (P<0.001) in all diabetic groups, compared with non-diabetic controls. A decrease (P<0.01) in glucose levels was observed in diabetic rats receiving L. brevis DPC 6108, compared with diabetic-controls. Both the composition and diversity of the intestinal microbiota were affected by diabetes. Microbial diversity in diabetic rats supplemented with low GABA was not reduced (P>0.05), compared with non-diabetic controls while all other diabetic groups displayed reduced diversity (P<0.05). L. brevis DPC 6108 attenuated hyperglycaemia induced by diabetes but additional studies are needed to understand the mechanisms involved in this reduction.

This study examined the anti-diabetic effects of aqueous extracts of Dendropanax morbifera leaves (DMWEs) in streptozotocin-induced diabetic Sprague-Dawley (SD) rats. Thirty male SD rats (body weight [BW], 250.4 ± 19.7 g) were divided into the following six groups: normal control rats (NC), diabetic control rats (DC), diabetic rats treated with metformin HCl 100 mg/kg BW (DT), diabetic rats treated with DMWEs 50 mg/kg BW (DM-50), diabetic rats treated with DMWEs 100 mg/kg BW (DM-100), and diabetic rats treated with DMWEs 200 mg/kg BW (DM-200). From two weeks of administration of DMWEs, the BW of all groups treated with DMWEs increased significantly compared to DC (p < 0.05). At four weeks after treatment, the blood glucose levels in DT, DM-100, and DM-200 decreased below 200 mg/dL, while the glycated hemoglobin concentrations in all groups administered DMWEs were similar to those of NC and DT. Regarding the blood biochemical parameters, the levels of aspartate transaminase, alanine transaminase, blood urea nitrogen, and creatinine in DM-100 and DM-200 were similar to those in NC and DT. Overall, these results highlight the effectiveness of DM-100 in the treatment of diabetes.

Previous studies found that Kelulut Honey produced by Trigona spp. bees is able to prevent oxidative damage in various pathological conditions.  Thus, the present study aimed to determine whether Kelulut Honey could prevent the sperm and testicular damage in streptozotocin-induced diabetic rats. Male Adult male Sprague-Dawley rats were divided into four groups: Non-Diabetic (NDM), Non-Diabetic with Kelulut Honey supplementation (NDMKH), Diabetic without supplementation (DM) and Diabetic with Kelulut Honey supplementation (DMKH).  Kelulut honey was given at the dose of 2.0 g/kg weight daily via gavage for 28 consecutive days. Results showed that sperm quality produced by diabetic rats supplemented with Kelulut honey significantly improved compared to the diabetic control groups (p<0.05). SOD activity and GSH level increased significantly (p<0.05) whereas PC and MDA levels significantly decreased in sperm and testis of DMKH rats when compared to DM rats (p<0.05). Histological observation showed obvious increase in spermatozoa in the lumen of epididymis and increased spermatogenic cells density in the testis of DMKH group.  In conclusion, Kelulut Honey has a potential in preventing the damage of sperm and testis in diabetic rats.

Patterns of eating behavior, body weight gain, and hormone changes were examined in normal-weight albino Sprague-Dawley rats on macronutrient diets. These diets consisted of either three separate jars with pure macronutrients, fat, carbohydrate and protein, from which to choose, or a single diet with different concentrations of fat and carbohydrate. Similar patterns on the choice-diet and single-diet paradigms were observed. During the first 7–10 days on these diets but not subsequently, the rats consuming a fat-rich diet exhibit significant hyperphagia, an increase in both total and fat intake that produces higher body weight gain. Compared with a 10% fat diet, a 30% fat diet is associated with a decline in insulin and corticosterone (CORT) levels, whereas a 60% fat diet produces an increase in circulating glucose. Levels of glucose are positively correlated with fat intake, and together these measures are consistently related to body fat. These relationships are most strongly expressed in rats that consume a fat-rich diet with >30% fat. Whereas insulin levels are also positively related to body fat, CORT is inversely related in these normal-weight subjects. In animals consuming a high-fat diet, a clear separation can be seen between “obesity-prone” (OP) rats with 100% greater body fat than “obesity-resistant” (OR) rats. The OP rats, which consume 15% more total calories, have significantly higher insulin and glucose levels. In animals that consume a diet with >30% fat, it is the OP but not the OR rats that exhibit a positive relation between fat intake, glucose levels, and body fat and reveal an additional association between carbohydrate intake, insulin, and body fat. Thus these rats on macronutrient diets exhibit distinct traits that relate behavior to hormone disturbances and adiposity and distinguish subjects that are prone vs. resistant to obesity.

The effects of long-term diabetes (4 wk) on the development of parametrial (PWAT) and retroperitoneal (RWAT) white adipose tissues were studied in young Sprague-Dawley rats (170-200 g) injected with a single dose of streptozotocin (75 mg/kg). Diabetes stopped animal growth and totally abolished the normal increases in the wet weight, total protein content, and cellularity (estimated by DNA content) of PWAT and RWAT. Remarkably, the prolonged lack of insulin induced a progressive decrease of the cellularity of RWAT to levels that were lower than those of the initial controls. It also resulted in a marked reduction of adipocyte size. The tiny adipocytes seen in diabetic animals were characterized by the presence of multilocular triglyceride droplets. In general, the decreases in cell number, cell size, and protein content were more pronounced in RWAT than in PWAT. Quantitative cellular frequency studies revealed that adipocytes, and possibly also endothelial cells, contribute to the decrease in RWAT cellularity. The results demonstrate that 1) diabetes inhibits proliferative activity in adipose tissue, 2) total cell number reduction may occur in adipose depot of young growing rats, 3) this effect is depot dependent, and 4) the turnover of adipocytes and endothelial cells is relatively slow (several weeks).

Brain damage due to severe hypoglycemia occurs in insulin-treated people with diabetes. This study tests the hypothesis that chronic insulin therapy that normalizes elevated blood glucose in diabetic rats would be neuroprotective against brain damage induced by an acute episode of severe hypoglycemia. Male Sprague-Dawley rats were split into three groups: 1) control, non-diabetic; 2) STZ-diabetic; and 3) insulin-treated STZ-diabetic. After 3 wk of chronic treatment, unrestrained awake rats underwent acute hyperinsulinemic severe hypoglycemic (10–15 mg/dl) clamps for 1 h. Rats were subsequently analyzed for brain damage and cognitive function. Severe hypoglycemia induced 15-fold more neuronal damage in STZ-diabetic rats compared with nondiabetic rats. Chronic insulin treatment of diabetic rats, which nearly normalized glucose levels, markedly reduced neuronal damage induced by severe hypoglycemia. Fortunately, no cognitive defects associated with the hypoglycemia-induced brain damage were observed in any group. In conclusion, antecedent blood glucose control represents a major modifiable therapeutic intervention that can afford diabetic subjects neuroprotection against severe hypoglycemia-induced brain damage.

This study tested whether leptin restores sympathetic-vagal balance, heart rate (HR) variability, and cardiac baroreflex sensitivity (BRS) in streptozotocin (STZ)-induced diabetes. Sprague-Dawley rats were instrumented with arterial and venous catheters, and a cannula was placed in the lateral ventricle for intracerebroventricular (ICV) leptin infusion. Blood pressure (BP) and HR were monitored by telemetry. BRS and HR variability were estimated by linear regression between HR and BP responses to phenylephrine or sodium nitroprusside and autoregressive spectral analysis. Measurements were made during control period, 7 days after induction of diabetes, and 7 days after ICV leptin infusion. STZ diabetes was associated with hyperglycemia (422 ± 17 mg/dl) and bradycardia (−79 ± 4 beats/min). Leptin decreased glucose levels (165 ± 16 mg/dl) and raised HR to control values (303 ± 10 to 389 ± 10 beats/min). Intrinsic HR (IHR) and chronotropic responses to a full-blocking dose of propranolol and atropine were reduced during diabetes (260 ± 7 vs. 316 ± 6, −19 ± 2 vs. −43 ± 6, and 39 ± 3 vs. 68 ± 8 beats/min), and leptin treatment restored these variables to normal (300 ± 7, −68 ± 10, and 71 ± 8 beats/min). Leptin normalized BRS (bradycardia, −2.6 ± 0.3, −1.7 ± 0.2, and −3.0 ± 0.5; and tachycardia, −3.2 ± 0.4, −1.9 ± 0.3, and −3.4 ± 0.3 beats·min−1·mmHg−1 for control, diabetes, and leptin) and HR variability (23 ± 4 to 11 ± 1.5 ms2). Chronic glucose infusion to maintain hyperglycemia during leptin infusion did not alter the effect of leptin on IHR but abolished the improved BRS. These results show rapid impairment of autonomic nervous system control of HR after the induction of diabetes and that central nervous system actions of leptin can abolish the hyperglycemia as well as the altered IHR and BRS in STZ-induced diabetes.

Objective: To study and compare the effect of Poly herbal plant extract (PHPE) with Glibenclamide (GL) on various parameters in Streptozotocin (STZ) induced diabetic rats. Methods: Diabetes was induced by combining High Fat-diet and injecting low dose Streptozotocin (35 mg/kg body wt.) to Sprague-dawley rats. Diabetic rats were treated with chloroform leaf extract of Azadirachta indica, aqueous leaf extract of Bougainvillea spectabilis and ethanolic seed extract of Trigonella foenum graecum combined in ratio of 1:2:3 respectively at dose of 600 mg/kg body weight by oral gavaging for 28 days. The results were compared with standard anti diabetic drug Glibenclamide given in dose of 500 µg/kg body weight. Results: Increase in body weight of both PHPE and GL treated diabetic rats was found to be statistically significant (p<0.05) compared to diabetic control rats. Decline in FBG levels of both PHPE and GL treated diabetic rats were found to be highly significant statistically (p<0.001) when compared to diabetic control rats at the end of study. Total Cholesterol (TC) and Triglycerides level in diabetic rats treated with PHPE were found to be highly statistically significant (p<0.001) compared to diabetic control rats. Pancreas of PHPE treated diabetic rats revealed partial restoration in size and number of islet of langerhans. Reduction in widening between acinar and islet cells noted. Glibenclamide treated diabetic rats showed much more improvement in pancreatic cell architecture by returning to its normal structure and size. Conclusion: In present study PHPE has shown to decrease elevated FBG level and improve in body weight at the end of study in diabetic rats which can be suggested due to modification in carbohydrate metabolic pathways, stimulation of insulin production by the pancreas, increased peripheral utilization of glucose in the cells and regeneration of β-cells of the pancreas.

Introduction: This study examined the antihyperglycemic effect of curry leaves, Murraya koenigii “MK” aqueous extract, and to examine its possible protective effects on the Islets of Langerhans and kidneys in streptozotocin (STZ) induced diabetic rats.  Methods: Thirty healthy adult male Sprague Dawley rats were randomized into five groups (n=6); normal control, normal treated with “MK” control, diabetic control (non-treated with “MK”), diabetic treated with 200mg/kg MK aqueous leaf extract and diabetic treated with 400mg/kg MK aqueous leaf extract. Blood glucose levels and body weight were monitored. The animals were sacrificed on the 30th day; the kidney and pancreatic tissues were processed for histological studies. Results: The diabetic control group significantly (p<0.001) showed considerable loss of body weight and increase in blood glucose levels and degeneration of the glomeruli and renal convoluted tubules and atrophied islets with disintegration of β-cells. Treatment of diabetic rats with aqueous extract showed significant (p<0.001) improvement in blood glucose levels and body weight gain.  The MK extract also caused an improvement in tissue injury induced by STZ injection in the kidney and endocrine pancreas.  Conclusions: These findings highlighted the beneficial effects of MK aqueous extract against cellular oxidative damage in STZ-induced diabetic rats.

 Objective: The objective was to study the evaluation of antidiabetic and antioxidant activity of different doses ethanolic extract of Mikania scandens leaves.Methods: The rats were divided into five groups of six animals each (non-diabetic control, diabetic control, standard drug-treated, and plant treated groups (250 and 500 mg/kg body weight)). Diabetes was induced in the healthy male Wistar rats (150–200 g body weight, 4–6 weeks old) by the administration of alloxan monohydrate (150 mg/kg, i.p.). On the 0th, 3th, 7th, 11th, and 15th days, the blood samples were analyzed for blood glucose. The antioxidant and antidiabetic parameters were evaluated by standard protocol. The liver tissue was used for histopathological assessment of liver damage.Results: The ethanolic extract of leaves of M. scandens showed a significant reduction (p<0.001) in the blood glucose levels and the antioxidant levels, with 500 mg/kg of body weight in the alloxan-induced diabetic rats as compared to the controls. Histopathological studies provided evidence that the leaf extract possesses antidiabetic activity.Conclusions: The ethanolic extract of leaves of M. scandens showed potent antidiabetic and antioxidant abilities against alloxan-induced rats, which indicate the presence of hypoglycemic constituents in the plant.
