Wound healing has been shown to be altered in diabetes mellitus. The aim of this study was to identify the effects of streptozotocin-induced diabetes on osseointegration. Diabetes was induced in 40-day-old rats by intraperitoneal injection of 70 mg per kg streptozotocin. At 14 days postinjection, implants were placed in the femora of 10 diabetic and 10 age-matched normal rats. Animals were sacr...

To investigate whether Ang II type-1 (AT1) receptor blockade could protect kidney mitochondria in streptozotocin-induced type-I diabetes, 8-week-old, male Sprague-Dawley rats received: a single streptozotocin injection (65 mg/kg, i.p.) (STZ group); streptozotocin and drinking water containing losartan (30 mg/kg/d) (STZ+Los group), or amlodipine (3 mg/kg/d) (STZ+Amlo group); or saline (i.p.) and...

Diabetes and atherosclerosis have been proposed to be influenced by immune and autoimmune mechanisms. A common incriminated antigen in both disorders is the heat shock protein (HSP)-60/65. In the current study, we established a model combining hyperglycemia with hyperlipidemia in LDL receptor-deficient (LDL-RD) mice and assessed its possible influences on lipid profile, HSP60/65, and atherogene...

Changes in the structural and functional properties of collagen caused by advanced glycation might be of importance for the etiology of late complications in diabetes. The present study was undertaken to investigate the influence of oral administration of aqueous pod extract (200 mg/kg body weight) of Phaseolus vulgaris, an indigenous plant used in Ayurvedic Medicine in India, on collagen conte...

Diabetes mellitus is a complex multifarious metabolic disorder characterized by chronic hyperglycemia that requires non-stop treatment with multiple factors will reduce the risk of long-term complications and drug side effects. Streptozotocin well known for its selective pancreatic islet β-cell cytotoxicity used to induce diabetes in animals. It also interferes cellular oxidative mechanisms. Ph...

Nitric oxide synthase activity was measured in Langerhans islets isolated from control and streptozotocin diabetic rats. The activity of the enzyme was linear up to 150 micrograms of protein from control rats and was optimal at 0.1 microM calcium, when it was measured after 45 min of incubation at 37 degrees C in the presence of 200 microM arginine. Specific activity of the enzyme was 25 x 10(-...

In the present study, powdered suspension of 'Glyoherb'- sugar control granules, a polyherbal formulation (manufactured by Dhanvantri Guj. herb., Valasan, Anand, Gujarat, India) was evaluated for its antihyperglycemic, antihyperlipidemic and antioxidant effects against normal and streptozotocin-induced diabetic rats. Type I diabetes was induced when streptozotocin 70 mg/kg was administered as a...

Antihyperglycemic potential of hyperin at 25 and 50 mg/kg doses for 30 days to streptozotocin induced diabetic rats has been reported. In oral glucose tolerance test, hyperin treated rats showed a significant reduction in blood glucose level after 120 min. It was found that hyperin exhibited dose dependent and significant antihyperglycemic activity in streptozotocin induced diabetic rats which ...

Many minor components of foods, such as secondary plant metabolites, have been shown to posses antioxidant activities, improving the effects of oxidative stress on diabetes and other disease conditions. This study evaluates the effect of aqueous extracts from Vernonia amygdalina leaves on lipid profiles and oxidative stress in streptozotocin induced diabetic rats. The results showed that the st...

The ethanolic extract of W. fruticosa flowers (250 and 500 mg/kg) significantly reduced fasting blood glucose level and increased insulin level after 21 days treatment in streptozotocin diabetic rats. The extract also increased catalase, superoxide dismutase, glutathione reductase, glutathione peroxidase activities significantly and reduced lipid peroxidation. Glycolytic enzymes showed a signif...
