Serum leptin in pups and breeders. A. Mean serum leptin concentration in pups at 35, 100, and 200 days of age. Symbols and error bars represent means ± SEM for each dietary group at each time point. At 35 days N = 23–24 rats/group, at 100 days N = 15–16 rats/group, and at 200 days N = 8 rats/group. At each time point, means not sharing a common superscript are significantly (p < 0.05) different by Fisher's pairwise comparisons. At 35 days only Se had a significant effect (p < 0.001) on serum leptin concentrations. At 100 days both Se (p = 0.001) and isoflavones (p = 0.033) had significant main effects. At 200 days only isoflavone intake had a significant main effect (p < 0.001). B. Mean serum leptin concentration in male breeders at 336 days. Only the main effect of isoflavones was statistically significant (p = 0.004). Means not sharing a common superscript are significantly (p < 0.05) different by Fisher's pairwise comparisons.
