Abstract:
w-3 polyunsaturated fatty acids, particularly docosahexaenoic acid (DHA) , are essential components for the development of human brain. A fish oil product enriched with DHA (51. 65%) was used to conduct a preliminary memory study with rats employing the active avoidance test. Three doses of DHA, 1. 0 g/kg, 200 mg/kg and 40 mg/kg, were administered orally to the rats twice daily for 20 days. The results showed that there was a positive correlation between the effects on memory ability and DHA adiministration, and the effects were dose responsive. The results also showed that DHA, at 200 mg/kg, could antagonize dysmnesia caused by scopolamine and had hypermnesia effect.
