Avaliação dos efeitos da dieta à base de óleo de amendoim (Arachis hypogaea) sobre os parâmetros comportamentais de ratos Wistar.

Abstract

Peanut oil has in its composition substantial amounts of mono- fatty acids and polyunsaturated, which have been linked to metabolic modulations beneficial to the human organism. Besides being a good alternative to replace animal fat, these fatty acids help in many cellular functions, such as integrity and fluidity of membranes, enzyme activity, lipid-protein interactions, eicosanoid synthesis, prevention and treatment of chronic diseases. In view of this, this study aimed to evaluate the behavioral effects of rats of the Wistar strain supplemented with peanut oil over a period of 3 weeks. The animals were divided into two groups: control group (CG) - supplemented with 1 ml water / 100g kilogram of body weight, and peanut oil Group (GO) - supplemented with 1 ml peanut oil / 100g kilo Weight. Behavioral tests were performed using the apparatus of the Open Field (CA) and Maze in Cruz High (LCE). The parameters observed in the open field were: Ambulation, Auto Clean (groomming), defecation and foot holding (rearing). For the elevated plus maze were observed: Entries numbers in Closed Arms (NEBF), Time Spent in the Closed Arms (TBF), Input Numbers in Open Arms (NEBA), Time Spent in the Open Arms (TBA), spending time Central Area (TC) and the amount of Head of Dives (MG). According to the survey results, the group supplemented with peanut oil showed anxiogenic behavior compared to the control group, and evidenced by the decrease in ambulation parameter of the open field, and by increasing the residence time in the closed arms of the maze Cruz High. The other parameters of the open field and elevated plus maze showed no significant differences between groups, p <0.05. From these findings it can be concluded that the peanut oil showed anxiogenic effects in animals, more research is needed with the oil so that it can have better conclusions regarding this effect.
