| Outline of Final Research Achievements |
The effects of dietary sialic acid in dams on the learning abilities of their pups after weaning were investigated using rats deficient in n-3 fatty acids. During pregnancy and lactation, the female rats were fed the n-3 fatty acid-deficient diet. After weaning, these pups fed the n-3 fatty acid-deficient diet (control)or N-acetlyneuramic acid ontaining n-3 fatty acid-deficient diet.
The learning abilities of the pups were evaluated using an active avoidance test. The pups fed N-acetlyneuramic acid ontaining n-3 fatty acid-deficient diet had high score in active avoidance test than control. the result suggested that N-acetlyneuramic acid feeding had an improving effect on learning and memory behavior.
