Efeito do consumo de peixes gordurosos amazônicos sobre o metabolismo lipídico de ratos wistar.

Abstract

Obesity is a disease that occurs due to the unbalance between the ingested energy and the spent energy to maintain the vital processes. Obesity has incresingly wrong and reached, nowadays, and epidemic level. It has also been considered the main public health issues in modern society. It is asociated with the rising risk of developing Diabetes Melliteus, cardiovascular diseases, dislipodemia, and several other chronic diseases. The diet based on fat maybe crucial reason to develop such diseases. The fishing also provides a large sort of food to thousands of local inhabitants nutrional development. Among the most well-known and consumed Amazon fish there is Tambaqui (Colossoma macropomum), Matrinxã (Brycon cephalus) and Mapará (Hypophthalmus edentatus), which are all considered very fat species. And so, the main purpose of this essay is to analyse the effects of a diet based on Amazon fat fish (Mapará, Matrinxã and Tambaqui) on male mice lipydic metabolism from wistar blood line. They were feeded with Adlibitum for 14 days. To make it happen doses of total cholesterol and triglycerids, glycoses, proteins and plasma lipydic fraction were made. The rate of lypogenesis again in vivo has been measured on RET, EPI, FIG and CARC, by incorporating 3 H2O in lipy. Our results show that the enrichment of a diet based on Amazon fat fish has altered the mice lipydic metabolism, dicreased effectively the lipid plasmatic concentration (Col. TG, e LDL) and increased the HDL besides the lipolitic activity on fatty tissues has grown after 4 weeks of feeding. Admiting that the ingestion of hiperlipydic diets may have caused an aterogenic effect, mainly because they have reduced certain lipydic fractions that have been claimed to cause serious vascular problems.
