Outline of Final Research Achievements

We assessed biodistribution of docosahexaenoic acid (DHA) in normal condition rat and amega-3 fatty acid deficiency rat. We administered C-14-radiolabelled DHA (1-[14C]-DHA) to 8-week-old normal rats and experimental rats which had been fed a non-ogega-3 fatty acid diet for 4 weeks, and then sacrificed them to investigate the biodistribution of 1-[14C]-DHA. In experimental groups, 1-[14C]-DHA uptake ratio of liver increased, and on the other hand, peak time of 1-[14C]-DHA uptake was delayed, compared with control groups.
