Efeitos terapêuticos da suplementação de L-arginina nas doenças cardiovasculares e endócrino-metabólicas

Nitric oxide is synthesized from L-arginine and plays an important role in blood pressure regulation, platelets aggregation and atherosclerosis development. Most of the studies have shown that the beneficial effects of the L-arginine supplementation are related to an increasing of nitric oxide bioavailability to the cells, improving the endothelial dysfunction, decreasing oxidative stress, ameliorating lipid profile and insulin resistance. However some studies show conflicting results. Considering the role of the endothelium on the pathogenesis of the cardiovascular diseases as well as on the endocrine-metabolic diseases, this review will update studies involving the role of nitric oxide and its signaling pathways in the regulation of vascular function. Furthermore, this review will focus on the main results of the clinical trials using oral L-arginine supplementation, with or without physical exercise, in an attempt to obtain beneficial effects on the cardiovascular and endocrine-metabolic systems in patients and healthy subjects.

Suplementação de acidificantes em rações de leitões desmamados: Desempenho e digestibilidade

In two experimental assays it was evaluated the diet acidifier supplementation effect on performance (assay 1) and on nutrient apparent digestibility coefficients (assay 2). During 42 days in assay 1, 120 piglets weaned at 21-days years old were allotted in8eight experimental block design with3three pigs per experimental unit. The treatments were a control and4four acidified diets. In assay 2,0ten piglets with an average weight of 16,4 kg were allotted in two experimental block design receiving two treatments under five replications (control diet without acidifier or supplied with 1,0% fumaric acid). On performance study the fumaric acid inclusion in the diet permitted a feed intake increase from 0 to 15 days, and weight gain from 0 to 32 days and from 0 to 42 days. In assay 2, the diet 1,0% of fumaric acid inclusion did not modified the apparent digestibility coefficients of dry matter and moreover diet chemical compounds. The similar apparent digestibility coefficient of dietetic nutrients with the acidifier inclusio, probabl, occurred due to the short period of evaluation. The fumaric acid inclusion in weaned piglet diets improved performance of piglets.
