Avaliação preliminar do efeito da Physalis angulata L. sobre a obesidade induzida por dieta hipercalórica

The obesity has been considered one of the most serious public health problem in the worldwide scale, especially for being one of the main risk factors for many chronic diseases that characterize the metabolic syndrome. In addition to these diseases, obesity also causes dermatoses that affect not only the individual emotions but also cause various cutaneous infections. Thus, overweighting can be an agent that causes many types of stress: psychological, physical and social. In order to improve people’s life quality, several ethnopharmacological studies indicate plant species for the treatment of disorders associated with obesity due to the attraction of this regimen is perceived as safer and more health effective when compared to the treatment performed by traditional anorectic substances. If considered both food intake and also oral treatment with different compounds can promote change in the gene expression, besides an appropriate diet has been maintenance mechanism of body's vital functions. The aim of this work was to develop new standard methods for induced obesity and stress, which stress is induced through physical and psychogenic stressors in Swiss male mice. Also to evaluate the effect of supercritical extract of Physalis angulata L. on the food intake and corporeal weight loss

Toxicity of dietary restriction of fat enriched diets on cardiac tissue

The present study examines the effects of caloric restriction in cardiac tissue evaluation markers of oxidative stress. High-fat dietary restrictions can have a long-term impact on cardiac health. Dietary restriction of control diet increased myocardial superoxide dismutase (SOD) and catalase activities. Dietary restriction of fatty acid-enriched diets increased myocardial lipoperoxide concentrations, while SOD activity was decreased in cardiac tissue of rats with dietary restriction of fatty acid-enriched diets. Dietary restriction of unsaturated fatty acid-enriched diet induced the highest lipoperoxide concentration and the lowest myocardial SOD activity. Dietary restriction of unsaturated fatty acid decreased myocardial glycogen, and increased the lactate dehydrogenase/citrate synthase ratio. Dietary restriction of fatty acid-enriched diets were more deleterious to cardiac tissue than normal ad lib.-fed diet. In conclusion, the effects of caloric restriction on myocardial oxidative stress is dependent on which nutrient is restricted. Dietary restriction of fatty acid-enriched diets is deleterious relative to ad lib.-fed chow diet. (C) 2002 Elsevier, Science Ltd. All rights reserved.

Studies on carbon-13 turnover in eggs and blood of commercial layers

This paper aimed at evaluating the influence of diets containing different isotopic values of carbon-13 turnover on the half-life of egg (yolk + albumen), yolk and albumen individually, and blood of poultry using δ‰ 13C isotopic variation. Commercial layers fed four experimental isocaloric and isonitrogenous diets (RC 4, RC 3, RMC 4 and RMC 3) containing different isotopic values, during an experimental period of 56 days. Turnover of the studied tissues was influenced by the experimental diets. Blood and albumen were more influenced by dietary treatments as compared to egg and yolk. The RMC 3 diet induced better performance (better feed intake and higher egg production) due faster rate of carbon substitution than the RC 4 diet, and lower half-life for egg (yolk + albumen), yolk, and albumen.

Diet compounds, glycemic index and obesity-related cardiac effects

Background: Diet compounds may influence obesity-related cardiac oxidative stress and metabolic sifting. Carbohydrate-rich diet may be disadvantageous from fat-rich diet to cardiac tissue and glycemic index rather than lipid profile may predict the obesity-related cardiac effects.Materials and methods: Male Wistar rats were divided into three groups (n=8/group): (C) receiving standard chow (3.0 kcal/g); (CRD) receiving carbohydrate-rich diet (4.0 kcal/g), and (FRD) receiving fat-rich diet (4.0 kcal/g). Rats were sacrificed after the oral glucose tolerance test (OGTT) at 60 days of dietary treatments. Lipid profile and oxidative stress parameters were determined in serum. Myocardial samples were used to determine oxidative stress, metabolic enzymes, glycogen and triacylglycerol.Results: FRD rats showed higher final body weight and body mass index than CRD and C. Serum cholesterol and low-density lipoprotein were higher in FRD than in CRD, while triacylglycerol and oxidized low-density lipoprotein cholesterol were higher in CRD than in FRD. CRD rats had the highest myocardial lipid hydroperoxide and diminished superoxide dismutase and catalase activities. Myocardial glycogen was lower and triacylglycerol was higher in CRD than in C and FRD rats. Although FRD rats had depressed myocardial-reducing power, no significant changes were observed in myocardial energy metabolism. Myocardial beta-hydroxyacyl coenzyme-A dehydrogenase and citrate synthase, as well as the enhanced lactate debydrogenase/citrate synthase ratio indicated that fatty acid degradation was decreased in CRD rats. Glycemic index was positively correlated with obesity-related cardiac effects.Conclusions: Isoenergetic carbohydrate-rich and fat-rich diets induced different degree of obesity and differently affected lipid profile. Carbohydrate-rich diet was deleterious relative to fat-rich diet in the heart enhancing lipoperoxidation and shifting the metabolic pathway for energy production. Glycemic index rather than dyslipidemic profile may predict the obesity effects on cardiac tissue. (C) 2007 Elsevier B.V. All rights reserved.
