| Popis: | Introduction: Obesity is a serious health issue worldwide. Feeding habits and stress are among the environmental factors that contribute to its development. Additionally, it’s been described an association between obesity and cognitive function, being pointed as a risk factor for Alzheimer’s disease. Objectives: To study the effect of a high-fat diet (HFD) consumption and the development of cognitive deficit. To evaluate whether the exposition to chronic mild stress aggravates the metabolic and/or cognitive disorders induced by the HFD. Furthermore, being the metformin (MET) a drug commonly used to treat diabetes, we will study its effects on behavior. Methodology: One month old, Male C57Bl/6J mice were fed with a standard diet (SD; 2.96 kcal/g) or a high-fat diet (HFD; 4.37 kcal/g) during 28 weeks. At the 8th week of diet, animals were divided and a group of each diet were chronically exposed to random mild stressors (CMS). After 12 weeks of diet, a group of animals under each treatment were given MET (250 mg/kg*day). We studied the glucidic (basal glycemia, glucose tolerance, insulinemia) and lipidic metabolism (total cholesterol, HDL cholesterol, triglycerides) and we studied the behavior (learning, spatial memory, working memory). |
