The purpose of this study was to investigate whether chronic administration of docosahexaenoic acid is able to reduce spatial cognitive deficit following transient ischemia in rats. In addition, we investigated whether the chronic treatment of docosahexaenoic acid is able to protect the hippocampal neuronal damage induced by either hypoxia in vitro or(More)
Prolonged dietary restriction has been reported to suppress age-induced phenomena. In order to investigate how prolonged caloric restriction reduces age-related deterioration of hippocampal synaptic transmission, we compared the levels of major hippocampal polyunsaturated fatty acids, arachidonic acid and docosahexaenoic acid between 4- and 26-month-old(More)
There are several lines of evidence indicating that membrane AA correlates with the ability of aged rats to sustain LTP. The age-related decrease in membrane AA seems to be triggered by increased lipid peroxidation, which is involved with the decline of LTP. The chronic treatment of DHA could decrease membrane AA without an increase in lipid peroxidation.(More)
