Аннотация
Neonatal hypoxic-ischemic (HI) encephalopathy is a major cause of perinatal morbimortality. There is growing evidence that n-3 polyunsaturated fatty acids, especially docosahexaenoic acid (DHA), attenuate brain injury. This study aimed to investigate the possible neuroprotective effect of maternal intake of flaxseed, rich in DHA׳s precursor α-linolenic acid, in the young male offspring subjected to perinatal HI. Wistar rats were divided in six groups, according to maternal diet and offspring treatment at day 7: Control HI (CHI) and Flaxseed HI (FHI); Control Sham and Flaxseed Sham; Control Control and Flaxseed Control. Flaxseed diet increased offspring׳s hippocampal DHA content and lowered depressive behavior. CHI pups presented brain mass loss, motor hyperactivity and poor spatial memory, which were improved in FHI rats. Maternal flaxseed intake may prevent depressive symptoms in the offspring and promote neuroprotective effects, in the context of perinatal HI, improving brain injury and its cognitive and behavioral impairments.
