N2 - The effect of 1 to 5 doses of 15,000 I.U. of vitamin A on N‐acetyl neuraminic acid (NANA) concentration in gingival tissue from rats was studied. Increased sialic acid concentration was observed in those animals receiving up to 4 doses of the vitamin, while a decreased concentration was found in the 5 doses group. Also examined was the interrelationship between vitamin A‐cortisol and vitamin A‐ascorbic acid. The profile of NANA variation in the groups receiving vitamin A plus ascorbic acid was similar to that of animals receiving only ascorbic acid. The data obtained for the groups receiving both vitamin A and cortisol, did not differ from that obtained for the groups receiving only vitamin A.
