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.

Abstract Aim and Objective The present study aims to investigate whether the antihyperglycemic effect of Murraya koenigii is mediated by antioxidant properties and insulin mimetic effect. Methods Thirty Spraque-Dawley rats were induced hyperglycemia by streptozotocin and nicotinamide (STZ-NA). The STZ-NA diabetic rats were treated with an ethanolic extract of Murraya koenigii 200 mg/kg b.w and 400 mg/kg b.w. One group was treated with glibenclamide (1 mg/kg b.w). After the administration of Murraya koenigii extract and glibenclamide for four weeks, the rats were sacrificed. Blood and organ samples were collected under a fasting condition. The body weight and blood glucose levels were measured. Hepatic enzymes were determined using a commercial kit, protein levels were estimated by Bradford’s method, and plasma insulin was assayed by an ELISA kit. Malondialdehyde (MDA) and reduced glutathione (GSH) levels were estimated by the TBA-Wills method and Ellman’s method, respectively. Results Ethanolic extract of Murraya koenigii showed a significant reduction in blood glucose level at both doses, 200 and 400 mg/kg b.w. In addition, Murraya koenigii exhibited a profound antioxidant effect with decreased MDA level and increased GSH level, particularly at the 200 mg/kg b.w. and significantly decreased the HOMA-IR index. Conclusions The present study reveals that Murraya koenigii possesses antidiabetic activity and antioxidant effects on STZ-NA induced diabetes mellitus.

Objective: The present study was aimed to evaluate the antidiabetic activity of ethanolic extract of the whole aerial plant of Portulaca grandiflora Hook on streptozotocin (STZ)-induced diabetic rats. Methods: Experimental diabetes was induced by a single dose of intraperitoneal injection of STZ (150 mg/kg). Adult male Wister albino rats were divided into five groups; normal control, diabetic control, diabetic glibenclamide (5 mg/kg), diabetic P. grandiflora H. extract (200 mg/kg), and diabetic P. grandiflora H. extract (400 mg/kg) for 21 days and analyzed for body weight (BW) and blood glucose. Results: The STZ-treated diabetic control rats showed a significant increase in blood glucose with a concomitant decrease in BW. Oral administration of P. grandiflora H. extract (200 and 400 mg/kg) and glibenclamide (5 mg/kg) for 21 days showed a significant reduction in blood glucose levels and elevation in the bodyweight studies as compared to control and glibenclamide-treated rats. Conclusion: The results of the present study showed that a potent antidiabetic activity was present in the aerial part of plant P. grandiflora H. extract.

Objective: The present work was executed to evaluate the anti-diabetic potency of a polyherbal preparation. The objective of this study is to induce experimental diabetes mellitus using streptozotocin in normal Albino wistar rats and study the antdiabetic activity of polyherbal formulation by comparison of changes in levels of glucose between normal and diabetic rats.Methods: The effect of methanol extract of poly herbal preparation containing aerial parts of Schrebera swietenoides, roots of Barleria montana and aerial parts of Rotula aquatica was investigated in normal and streptozotocin induced diabetic rats.Results: The lowest blood glucose levels were observed at 4 and 8th hr after the oral administration of 150 and 300 mg/kg b.w polyherbal formulation. The blood glucose levels at 24hrs after the oral administration of 150 and 300 mg/kg b. w of poly herbal formulation was significantly lowers the blood glucose levels.Conclusions: The display of synergy or antagonism by the composite herbal extracts in ameliorating hyperglycemia depended on the type and number of individual herbal extract used in constituting the experimental herbal formulations.

Abstract Although the antidiabetic effects of leptin require intact neuronal melanocortin signaling in rodents with uncontrolled diabetes (uDM), increased melanocortin signaling is not sufficient to mimic leptin's glucose-lowering effects. The current studies were undertaken to clarify the role of melanocortin signaling in leptin's ability to correct metabolic and neuroendocrine disturbances associated with uDM. To accomplish this, bilateral cannulae were implanted in the lateral ventricle of rats with streptozotocin-induced diabetes, and leptin was coinfused with varying doses of the melanocortin 3/4 receptor (MC3/4R) antagonist, SHU9119. An additional cohort of streptozotocin-induced diabetes rats received intracerebroventricular administration of either the MC3/4R agonist, melanotan-II, or its vehicle. Consistent with previous findings, leptin's glucose-lowering effects were blocked by intracerebroventricular SHU9119. In contrast, leptin-mediated suppression of hyperglucagonemia involves both melanocortin dependent and independent mechanisms, and the degree of glucagon inhibition was associated with reduced plasma ketone body levels. Increased central nervous system melanocortin signaling alone fails to mimic leptin's ability to correct any of the metabolic or neuroendocrine disturbances associated with uDM. Moreover, the inability of increased melanocortin signaling to lower diabetic hyperglycemia does not appear to be secondary to release of the endogenous MC3/4R inverse agonist, Agouti-related peptide (AgRP), because AgRP knockout mice did not show increased susceptibility to the antidiabetic effects of increased MC3/4R signaling. Overall, these data suggest that 1) AgRP is not a major driver of diabetic hyperglycemia, 2) mechanisms independent of melanocortin signaling contribute to leptin's antidiabetic effects, and 3) melanocortin receptor blockade dissociates leptin's glucose-lowering effect from its action on other features of uDM, including reversal of hyperglucagonemia and ketosis, suggesting that brain control of ketosis, but not blood glucose levels, is glucagon dependent.

Pisang Ambon (Musa paradisiaca L.) is one type of bananas usually consumed by Indonesian people. Besides its flesh which has high nutrition, its peels also has antioxidant activity. Antioxidants has the ability to reduce oxidative damage in people’s body with diabetes mellitus. Therefore, this study aimed to determine the antioxidant activity of the aqueous  extract of Pisang Ambon peels and to determine it’s effective dose as an antidiabetic agent in hyperglycemic mice. This study used male mice which all have been intravenously induced with alloxan at a dose of 50 mg/kgBW. They were then divided into five groups. The first two groups got Na CMC 0.5% (negative control) and glibenclamide 0.65 mg/kgBW (positive control), while the other three got  the aqueous  extract of Pisang Ambon peels successively at doses of 400, 800, and 1200 mg/kgBW. The data were statistically analyzed using ANOVA (Analysis of Variance) at 95% confidence interval with parameter of blood glucose levels difference between before and after treatment. The results showed that the aqueous extract of Pisang Ambon peels had antidiabetic activity at an effective dose of 400 mg/kgBW in hyperglycemic mice which was comparable to glibenclamide
