The current study investigated the ameliorative effects of combined therapy of glibenclamide and G. latifolium (GL) on several biochemical parameters of alloxaized Wistar rats. Thirty adult male Wistar rats assigned into 5 groups of 6 rats each were used for the study. Groups 2-5 were intraperitoneally injected with 160 mg/kg of alloxan monohydrate and upon establishment of diabetes (Fasting Blood Glucose (FBG) ≥ 126 mg/dl) were treated with 10 ml/kg distilled water (DW), 2 mg/kg glibenclamide, 200 mg/kg GL and 2 mg/kg glibenclamide and 200 mg/kg GL respectively. Rats in group 1 were not made diabetic and served as normal control. All the treatments were realized through daily oral route using gastric tube, for 21 days. Results indicated that the treatment of diabetic rats with a combination of glibenclamide and GL significantly reduced the elevated glucose levels, cholesterol, triacylglycerol, low density lipoprotein and malondialdehyde levels, along with increases in the high density lipoprotein, glutathione values and catalase activities, when compared to diabetic untreated group. It was concluded that the combined therapy of glibenclamide and GL showed superior antihyperglycemic, hypolipidaemic and antioxidant effects compared to either of them used alone.

The present study was to investigate the anti-diabetic activities ofSwertia bimaculata. Based on the glucose consumption ofS. bimaculataextractsand different fractions (petroleum, dichloromethane, ethyl acetate,n-butanol and water extracts) in 3T3-L1 adipocyte assay, ethanol (ETH) and dichloromethane (DTH) extracts had the most effective potency. Furthermore, ETH, DTH and corymbiferin (the most abundant component of DTH) were evaluated for anti-diabetic effects in high fat and sucrose fed combined with low dose streptozocin induced diabetic rats. DTH and corymbiferin displayed remarkable anti-diabetic activities. The fasting blood glucose levels were significantly decreased, while the serum insulin levels were obviously increased. The oral glucose tolerance was also improved. The lowed serum total cholesterol, low density lipoprotein (LDL) and triglyceride levels and increased ratio of HDL (high density lipoprotein)/LDL were observed. The insulin sensitivity was improved on the basis of increased expressions of insulin-receptor substrate-2, phosphatidylinositol 3-kinase and Ser/Thr kinase AKT2. And also DTH and corymbiferin improved antioxidant capacity and carbohydrate metabolism in diabetic rats, along with the improvement of histopathology of livers and pancreaticβcells. Corymbiferin was one of active constituents, responsible for anti-diabetic properties. Therefore,S. bimaculatacould be considered as an alternative agent against diabetes mellitus.

Aim.To study the associations between blood lipid profile and blood glucose levels in men with coronary heart disease (CHD), stable effort angina (SEA), metabolic syndrome (MS), and Type 2 diabetes mellitus (DM-2).Material and methods.The study included 82 men (mean age 50,5±0,9 years) with CHD, Functional Class I–III SEA, MS, and DM-2. The following lipid profile parameters were assessed: total cholesterol (TCH), triglycerides (TG), low-density lipoprotein cholesterol (LDL–CH), very low-density lipoprotein cholesterol (VLDL–CH), high-density lipoprotein cholesterol (HDL–CH), atherogenic index (AI), and triglyceride index (TGI), together with fasting blood glucose.Results.There were positive (direct) associations between higher levels (>90th percentile) of lipid profile parameters (TCH, TG, LDL–CH, VLDL– CH, HDL–CH, AI, TGI) and blood glucose, as well as between lower levels (≤10th percentile) of lipid profile parameters (TCH, TG, LDL–CH, VLDL– CH, AI, TGI) and blood glucose. At the same time, there were negative (inverse) associations between lower lipid levels (≤10th percentile of TCH, TG, LDL–CH, VLDL–CH, HDL–CH, AI, TGI) and higher glucose levels (>90th percentile), as well as between higher lipid levels (>90th percentile of TCH, TG, LDL–CH, VLDL–CH, HDL–CH, AI, TGI) and lower glucose levels (≤10th percentile).Conclusion.Dyslipidemia and hyperglycemia demonstrate synergetic proatherogenic effects in patients with CHD, SEA, MS, and DM-2, as suggested by significant heterogeneous (direct and inverse) associations between lipid profile parameters and fasting blood glucose. The results obtained provide an opportunity for the assessment of risk levels, prognosis, and need for pharmacological prevention and treatment in patients with combined cardiovascular pathology.

Pleurotus tuber-regiumcontains polysaccharides that are responsible for pharmacological actions, and medicinal effects of these polysaccharides have not yet been studied in diabetic rats. We examined the antidiabetic, antihyperlipidemic, and antioxidant properties ofP. tuber-regiumpolysaccharides in experimental diabetic rats. Forty rats were equally assigned as diabetic high-fat (DHF) diet and polysaccharides treated DHF groups (DHF+1P, DHF+2P, and DHF+3P, 20 mg/kg bodyweight/8-week). Diabetes was induced by chronic low-dose streptozotocin injections and a high-fat diet to mimic type 2 diabetes. Polysaccharides (1P, 2P, and 3P) were extracted from three different strains ofP. tuber-regium. Fasting blood glucose and glycosylated hemoglobin (HbA1c) levels substantially decreased, while serum insulin levels were restored by polysaccharides treatment compared to DHF. Furthermore, plasma total cholesterol, triglycerides, and low-density lipoprotein levels were significantly(P<0.01)lower in polysaccharide groups. High-density lipoprotein levels were attenuated with polysaccharides against diabetes condition. Polysaccharides inhibited(P<0.01)the lipid peroxidation index (malondialdehyde), and restored superoxide dismutase and glutathione peroxidase activities in the liver of diabetic rats. The antihyperglycemic property of polysaccharides perhaps boosts the antioxidant system that attenuates oxidative stress. We emphasize thatP. tuber-regiumpolysaccharides can be considered as an alternative medicine to treat hyperglycemia and oxidative stress in diabetic rats.

Objectives: Piper chaba, native to South and Southeast Asia, has been traditionally used as a medicinal plant. Aim of this study was to evaluate the antihyperglycemic and antihyperlipidemic activities of P. chaba root extracts (RE) in streptozotocin (STZ)-induced diabetic rats along with its antimicrobial activity. Methods: Diabetes was induced in Wister rats through the intraperitoneal administration of STZ (50 mg/kg b.w.). Antidiabetic and antilipidemic activities of the RE (in methanol, ethanol, ethyl acetate and distilled water) were evaluated by administering oral dose (200 mg/kg b.w.) for 21 days. Metformin (12.1 mg/kg b.w.) was used as a positive control. Blood samples of rats were drawn by tail vein puncture and cardiac puncture to determine the fasting blood glucose (FBG) and serum level of total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL), respectively. Standard protocols were followed to determine the antimicrobial and antibiofilm activities against two different strains of bacteria. Results: Oral administration of P. chaba RE for 21 days resulted in a significant (p< 0.001) decrease in FBG and TC, TG, and LDL levels (p<0.001), when compared to the untreated diabetic rats. Significant (p<0.001) increase of HDL was observed when ethyl acetate and aqueous RE were administered. Out of four, two extracts showed varying antimicrobial activities, particularly against the gram-positive bacteria.  Conclusion: It became evident for the first time that P. chaba extracts possess antimicrobial activities and can serve as biochemical compounds with great alternative therapeutic potential in the management of diabetes and hypercholesterolemia.

Background: Hyperlipidemia is a well known risk factor for cardiovascular disease, especially atherosclerotic coronary artery disease. Peroxisome proliferator activated receptor α (PPARα), a member of this nuclear receptor family, has emerged as an important player in this scenario, with evidence supporting a central co-ordinated role in the regulation of fatty acid oxidation, lipid and lipoprotein metabolism and inflammatory and vascular responses, all of which would be predicted to reduce atherosclerotic risk. The low-density lipoprotein (LDL) receptor (LDLR) is the primary pathway for removal of cholesterol from the circulation, and its activity is meticulously governed by intracellular cholesterol levels. Hence in this study we investigated the effect of Lutein on PPARα and LDLR expression in liver of wistar rats.Methods: Male Wistar rats were divided into 6 groups of 6 each. Group I served as control. Group II III, IV, V and VI rats were received high cholesterol diet. Group III was treated with Atorvastatin 5mg/kg. Group IV, V and VI rats were treated with 25mg/kg, 50mg/kg and 100mg/kg of Lutein. After 16 weeks, liver tissue samples were collected from all the groups of animals to evaluate the expression of PPARα and LDLR.Results: The expression of Peroxisome proliferator activated receptor α and low-density lipoprotein (LDL) receptor (LDLR) was significantly increased in Lutein treated hypercholesterolemic male wistar rats.Conclusions: The results of this study indicate that Lutein activates LDL receptor and PPARα in hypercholesterolemic male wistar rats.

The current study aimed to investigate the therapeutic effects of 5,7-dihydroxy-6-oxoheptadecanoic acid (DHA) from Tiliacora triandra on rat models of type 2 diabetes mellitus (T2DM). T2DM was induced with a combination of high-fat diet/streptozotocin (HFD/STZ), and diabetic rats were treated with DHA (25 mg/kg) for 30 days. The body weight, fasting blood glucose (FBG), serum, and liver biochemical parameters, as well as histological evaluations of the liver and pancreas, were evaluated. Diabetic rats displayed a significant increase in FBG, serum lipid profiles (triglycerides, total cholesterol, and low-density lipoprotein cholesterol), liver function enzymes (aspartate transaminase, alkaline phosphatase, and alanine transaminase), creatinine, liver malondialdehyde (MDA), and myeloperoxidase (MPO) contents. Furthermore, insulin level and liver antioxidant enzyme activities (catalase [CAT], superoxide dismutase [SOD], and glutathione peroxidase [GSH-Px]) were significantly reduced in the diabetic rats. Whereas, treatment with DHA significantly reduced FBG, serum lipids, liver function enzymes, serum creatinine, liver MDA, and MPO contents. In addition, treatment with DHA significantly increased serum insulin level and liver SOD, CAT, and GSH-Px activities. In addition, DHA alleviated histopathological changes in the pancreas and liver caused by T2DM. These results portray the antidiabetic and antioxidative properties of DHA and can be considered as a potential treatment for T2DM.

The antidiabetic and antioxidant potential ofTriticum aestivumwere evaluated by usingin vivomethods in normal and streptozotocin-induced diabetic rats. Diabetes was induced in the Wistar strain albino rats by injecting streptozotocin at a dose of 55 mg/kg body weight. Ethanolic extracts ofTriticum aestivumat doses of 100 mg/kg body weight were administered orally for 30 days. Various parameters were studied and the treatment group with the extract showed a significant increase in the liver glycogen and a significant decrease in fasting blood glucose, glycosylated hemoglobin levels, and serum marker enzyme levels. The total cholesterol and serum triglycerides levels, low density lipoprotein, and very low density lipoprotein were also significantly reduced and the high density lipoprotein level was significantly increased upon treatment with theTriticum aestivumethanol extract. A significant decrease in the levels of lipid peroxides, superoxide dismutase, and glutathione peroxidise and increase in the levels of vitamin E, catalase, and reduced glutathione were observed inTriticum aestivumtreated diabetic rats. Thus, from this study we conclude that ethanolic extract ofTriticum aestivumexhibited significant antihyperglycemic, hypolipidemic, and antioxidant activities in streptozotocin-induced diabetic rats.
