| The relationship between lipid peroxidation, antioxidant defense and diabetic osteopenia remains unclear. This study evaluated the relationship among lipid peroxidation index, antioxidant defense parameters and bone metabolism in a premenopausal diabetic model using measures including thiobarbituric acid-reactive substances concentration (TBARS) and reduced glutathione (GSH) content in brain homogenates, histomorphometric analysis, biomechanical testing and bone mineral density (BMD). Female Wistar rats with regular estrous cycle were divided into two groups: Group 1: control rats (n = 15) and Group 2: diabetic rats (n = 15). Diabetes was induced by alloxan and confirmed by glycemia >250 mg/dL. The lipid peroxidation index, measured by TBARS... |

| Diabetes Mellitus (DM) is a metabolic syndrome characterized by hyperglycemia. Chronic complications affect a number of organs, including the lungs. Cissampelos sympodialis Eichl (Menispermaceae) is a plant used to treat respiratory diseases. The aim of this study was to evaluate the effect of Cissampelos sympodialis extract (CSE) in lungs of diabetic rats. We used 30 Wistar rats divided into three groups: control group (CG), diabetic group (DG) and diabetic Cissampelos sympodialis treatment group (DTG). Diabetes was induced by streptozotocin (40 mg/kg i.v.). The CSE (400 mg/kg, po) was administered daily, during four weeks, beginning one week after the onset of DM. The treatment with CSE was not able to reduce blood glucose levels after streptozotocin... |

| ABSTRACT The aim of the present study was to investigate the bone mineral density (BMD) of patients with type 1 Diabetes mellitus (T1DM). We also assessed the association between osteoprotegerin (OPG) genetic polymorphisms and BMD. Genotyping was performed for 1181G>C and 163A>G OPG polymorphisms by allelic discrimination in 119 patients with T1DM and 161 normoglycemic (NG) individuals, aged 6 to 20 years old. Glycemic control, serum parameters of bone metabolism and BMD were evaluated. T1DM patients showed low BMD, poor glycemic control and decreased total calcium values when compared to controls (p < 0.05). For all the polymorphisms studied, the genotype and allele frequencies in patients with T1DM were not significantly different from the... |
