The rice fermented byMonascus, called red mold rice (RMR), and has a long tradition in East Asia as a dietary staple.Monascus-fermented dioscorea called red mold dioscorea (RMD) contains various metabolites to perform the ability of reducing oxidative stress and anti-inflammatory response. We used Wistar rats and induced diabetes by injecting streptozotocin (STZ, 65 mg/kg i.p.). RMD was administered daily starting six weeks after disease onset. Throughout the experimental period, significantly () lowered plasma glucose, triglyceride, cholesterol, free fatty acid and low density lipoprotein levels were observed in the RMD-treated groups. The RMD-treated diabetic rats showed higher activities of glutathione disulfide reductase, glutathione reductase, catalase and superoxide dismutase () in the pancreas compared with the diabetic control rats. RMD also inhibited diabetes-induced elevation in the levels of interleukin (IL)-1β, IL-6, interferon-γand tumor necrosis factor-α. Pancreaticβ-cells damaged by STZ in the RMD supplemented groups were ameliorated. The results of this study clearly demonstrated that RMD possesses several treatment-oriented properties, including the control of hyperglycemia, antioxidant effects, pancreaticβ-cell protection and anti-inflammatory effects. Considering these observations, it appears that RMD may be a useful supplement to delay the development of diabetes and its complications.

Objective: To evaluate the antioxidant and antihyperlipidaemic effect of methanol extracts of Asteracantha longifolia and Pergularia daemia leaf in alloxan induced diabetic rats. Methods: Swiss albino rats were made diabetic by a single dose of alloxan monohydrate (150 mg/kg i.p.). Blood glucose levels and body weights of rats were measured using on weekly intervals i.e day 0,7,14 and 21 after daily administration of both extracts at dose 200 mg/kg bw. Other biochemical parameters such as serum cholesterol, triglycerides, low density lipoprotein-cholesterol, very low density lipoprotein-cholesterol, high density lipoprotein-cholesterol, phospholipids and serum protein, albumin, globulin levels were also measured at the end of study. The antioxidant enzymes (CAT, SOD & GSH) were also measured in the diabetic rats. Results: In the acute toxicity study, methanol extract of both plants were non-toxic at 2000 mg/kg in rats. The increased body weight, decreased blood glucose and other biochemical parameters level were observed in diabetic rats treated with methanol extracts of both plants compared to diabetic control rats. The antioxidant activity of both plant extracts were also exhibited significant activity. In diabetic rats, methanol extract of both plants administration, altered lipid profiles were reversed to near normal than diabetic control rats. Conclusions: Methanol extract of both plants (Asteracantha longifolia and Pergularia daemia) leaf possesses significant antioxidant and antihyperlipidaemic activity in diabetic rats.

Background: Diabetes mellitus is a group of metabolic disorders which result to excessive accumulation of blood sugar over a prolonged period. Due to higher risk of diabetes mellitus to cardiovascular disease, it is crucial to identify and address these cardiovascular risks. This study assessed the effects of diabetes on levels of some blood lipids and its atherogenic indices in diabetic male rats. Methods: This is an experimental study that involved 40 apparently healthy adult male albino rats (wistar strain) which were randomly assigned to five groups (A, B, C, D and E) of eight (8) animals each. Group A (Normal Control of No intervention for 72 hours), Group B (Diabetic rats of 72 hours post diabetes induction), Group C (metformin treated diabetic rats), Group D (Diabetic Control untreated) and Group E (Normal Control of 3 weeks post diabetes induction). Seven milliliters of fasting blood sample were collected from all the subjects. Serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-c), low density lipoprotein cholesterol (LDL-c) and very low density lipoprotein cholesterol (VLDL-c) were determined using standard methods. Atherogenic indices, non HDL cholesterol (Non HDL-c), cardio risk ratio (CRR), atherogenic index of plasma (AIP), atherogenic coefficient (AC) and atherosclerosis index (AI) were calculated. It was analyzed statistically using SPSS version 23.0. Results: The mean values of HDL-c was significantly higher in the treated diabetic group when compared with untreated diabetic control (P<0.05) while TC, TG, LDL-c, VLDL-c, Non HDL-c, CRR, AIP, AC and AI were significantly lower in treated diabetics when compared to the untreated diabetic control (P<0.05). Also, blood mean levels of HDL-c were significantly lower in the diabetic groups (treated and untreated) when compared with non diabetic control (P<0.05) while TC, TG, LDL-c, VLDL-c, Non HDL-c, CRR, AIP, AC and AI were significantly higher in the diabetic groups (treated and untreated) when compared with non diabetic control (P<0.05). Conclusion: The study suggests that atherogenic indices can serve as predictive pointer for future cardiovascular event especially, when LDLc value is normal. Also hyperglycemia could cause significant alterations of lipids, but metformin treatment has showed not only hypoglycemic effect, but also anti-hyperlipidemic properties.

Ethanolic extracts of some fruits of Cucurbitaceae family such as Cucumis sativus (cucumber), Lagenaria siceraria (white pumpkin), Luffa acutangula (ridge gourd), Benincasa hispida (ash gourd), Citrullus lanatus (sweet melon) and Cucarbita maxima (pumpkin) have been studied for their hypoglycemic effects on alloxan induced diabetic rats (AIDRs). Screening results suggested that among the tested fruits the hypoglycemic potency follows: cucumber > white pumpkin > ridge gourd. These three fruit-extracts were further investigated for their hypoglycemic, hypolipidemic and glycogenesis effects. Cucumber, white pumpkin and ridge gourd extracts reduced blood glucose level by 67, 65 and 51%, respectively at 12 hours after single intraperitoneal injection; while reduced the low density lipoprotein (LDL) level to 13, 28 and 86%, respectively in AIDRs. The maximum reduction 87% was observed by cucumber extract. Cucumber, white pumpkin and ridge gourd extracts reduced total cholesterol level to 29, 15 and 38%, respectively comparing with the diabetic control group. Here the maximum reduction of 85% was observed by white pumpkin extract. Cucumber, white pumpkin and ridge gourd also reduced triglyceride levels to 72, 68 and 80%, respectively. Maximum reduction of 32% was observed by white pumpkin. Significant improvement of glycogenesis was also observed by ridge gourd extracts in AIDRs.© 2013 JSR Publications.

The current study was carried out to determine the hypoglycemic and hypolipidemic activities of methanolic extract P. silhetensis leaves in alloxan-induced diabetic rats. In this study diabetes was induced in rats by intraperitoneal administration of 150 mg/kg of alloxan. Animals were treated for one week with the plant extract at doses of 250 and 500 mg/kg body weight. Metformin (100 mg/kg b.w.) was used as standard for comparison. The anti-diabetes activity was examined by measuring blood glucose level at 0, 3, 5 and 7 days in diabetic induced animal models. Blood samples were collected at day eight of the treatment and analyzed for triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) after sacrifice. Alloxan-induced diabetic rats exhibited a significant decrease in plasma glucose level when treated with P. silhetensis leaf extract as compared to normal, diabetic control and standard rats. All tested lipid parameters were improved after the treatment with methanolic extract of P. silhetensis and metformin as compared to diabetic rats. The results of the present study showed that P. silhetensis possesses significant anti-diabetic properties and has beneficial effects on diabetic hyperlipidemia.

The present study evaluates the antihyperglycemic, antiperoxidative and antihyperlipidemic activities of saponins from Helianthus annuus roots in alloxan induced diabetic rats. Thirty rat’s weights between 100-150 g was used for the study and divided into six groups of five rats each. Group A was non-diabetic rats; the remaining five groups was induced intraperitoneal with 150 mg/kg of alloxan monohydrate. Group B was diabetic control, while group C, D, E and F was treated with saponin (100, 200, 300 and 500 mg/kg) for 21 days. Administration of saponins significantly reduced the elevated levels of glucose, decreased total cholesterol (TC), total triglycerides (TG), low density lipoprotein (LDL) and increased high density lipoprotein (HDL) in the serum towards normalcy compared to the diabetic control (p ˂ 0.05). In addition, saponins exhibited strong inhibition of lipid peroxidation and increased the levels of antioxidant enzymes (superoxide dismutase and catalase) in the liver, kidney and pancreas compared to the diabetic control (p ˂ 0.05). Results suggest that saponins from Helianthus annuus root can enhance the antihyperglycemic, antihyperlipidemic and antioxidant properties in alloxan-induced diabetic rats, and may have the potential to be used in the prevention or in the management of diabetes.

Context: Diabetes mellitus causes atherosclerosis and lipid abnormalities. Hypolipidemic and antioxidative properties of catechin (CTN) have been reported in several studies. Objective: This study assesses the possible protective effects of CTN against oxidative damage in the diabetic rats. Materials and Methods: The rats were divided into the control, untreated diabetic, and 3 CTN-treated diabetic groups (20, 40, and 80 mg/kg/d, intraperitoneal). The diabetic rats were induced by streptozotocin. Catechin was injected for 4 weeks. At the end of the experimental period, glucose, lipid profile, apoprotein A-I (apo A-I), apoprotein B (apo B), malondialdehyde (MDA) levels, and antioxidant enzymes including glutathione- S-transferase (GST), superoxide dismutase (SOD), and catalase (CAT) activities were determined in serum. Statistical analyses were performed using the InStat 3.0 program. Results: Streptozotocin caused an elevation of glucose, MDA, triglycerides (TGs), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and apo B with reduction in high-density lipoprotein cholesterol (HDL-C), apo A-I, SOD, CAT, and GST in the serum ( P < .05). The findings showed that the significant elevation in the body weight, glucose, MDA, TG, TC, LDL-C, and apo B and reduction in HDL-C, apo A-I, SOD, CAT, and GST were ameliorated in the CTN-treated diabetic groups versus the untreated group, in a dose-dependent manner ( P < .05). Conclusion: The present investigation proposes that CTN may ameliorate diabetes and its complications by modification of oxidative stress.

The antidiabetic, normolipidaemic, antioxidant and safety evaluations of ethanolic extract of Acacia ataxacantha roots (EEAAR) were investigated in streptozotocin - induced diabetic rats, to verify its use in traditional African medicine and as alternative to synthetic normoglycaemic agents in diabetic treatments. Thirty albino rats (Rattus novergicus) were randomized into six groups - control, diabetic control, EEAAR-treated at 125 mg/kg, 250 mg/kg, 500 mg/kg body weights (b.wts.) and metformin groups, respectively. Phytochemical screening showed the presence of alkaloids, polyphenols, flavonoid, saponins, tannins and terpenoid. Blood glucose was significantly reduced (p < 0.05) especially after 7 days of oral administration of EEAAR at 125 mg/kg b.wt with values (110.01 ± 9.64 mg/dl) similar to that of the control (106.33 ± 4.13 mg/dl). There was an increase (p < 0.05) in the ALT and AST activities of the liver and serum of rats in all the groups except in those that received 125 mg/kg b.wt. Serum total cholesterol, low density lipoprotein cholesterol and triglyceride were decreased (p < 0.05) upon administration of the extract and metformin. There was no difference (p > 0.05) in malondialdehyde concentration of rats administered with 125 mg/kg b.wt. of extract and metformin. Superoxide dismutase activity was elevated (p < 0.05) in all groups and compared favourably with the control in each of the tissues. This study revealed the antidiabetic and hypolipidaemic effects of EEAAR, which may be due to the antioxidant properties of some of the phytochemical constituents. However, the extract may not be safe at large and repeated doses.
