Data are presented as mean values ± se. The numbers in the parentheses indicate the sample size. The letters indicate ANOVA Tukey multiple comparison test groupings. Mean values with the same letter in the group are not significantly different (α = 0.05). Student's t test with dis3-3. *, P < 0.0001; **, P < 10E-11.
