ABSTRACT
OBJECTIVES:
To evaluate how safflower oil (SFO) influences brain electrophysiology and cortical oxidative status in the offspring, mothers received a diet with SFO during brain development period.METHODS:
Beginning on the 14th day of gestation and throughout lactation, rats received safflower (safflower group - SG) or soybean oil (control group - CG) in their diet. At 65 days old, cortical spreading depression (CSD) and cortex oxidative status were analyzed in the offspring.RESULTS:
SG presented reduction of the CSD velocity as compared to the CG (SG 3.24 ± 0.09; CG 3.37 ± 0.07â mm/min). SFO reduced levels of lipid peroxidation by 39.4%. SG showed the following increases glutathione-S-transferase, 40.8% and reduced glutathione, 34.3%. However, SFO decreased superoxide dismutase by 40.4% and catalase by 64.1%. To control for interhemispheric effects, since CSD was recorded only in the right cortex, we evaluated the oxidative status in both sides of the cortex; no differences were observed.DISCUSSION:
Data show that when SFO is consumed by the female rats during pregnancy and lactation, the offspring present long-term effects on brain electrophysiology and cortical oxidative state. The present study highlights the relevance of understanding the SFO intake of pregnant and lactating mammals.Palavras-chave
