Fig. (6) Cell death resulting from incubation with omega-6 fatty acids measured as PI florescence. Thymocytes were incubated with DTA, ARA or LNA for 30min, 1 and 1.5 hrs with various concentrations. Note that the scale for cell death is different from that in Figs. (4, 5). *Significantly different from control (p< 0.05).
