Figure 5. Effects of DP agonists and antagonists on the changes of neuronal viability caused by aluminium detected by the method of MTT.

(a) BW245C and (d) CAY10471 increased neuron viability in a concentration dependent manner in Al³⁺-treated group, whereas (b) BWA868C and (c) DK-PGD₂ decreased neuron viability in Al³⁺-treated group. Values were mean ± SD of eight individual experiments (n = 8, ^##P < 0.01 compared with control group, *P < 0.05 and **P < 0.01 compared with Al³⁺-treated group, respectively, one-way ANOVA with Dunnett’s multiple comparisons).
