Figure 5From: Dietary supplementation of soy germ phytoestrogens or estradiol improves spatial memory performance and increases gene expression of BDNF, TrkB receptor and synaptic factors in ovariectomized ratsThe levels of total and mature BDNF in the hippocampal tissue of ovariectomized rats. The levels (Mean ± SEM, n = 7) of total and mature BDNF in the hippocampal tissue of ovariectomized rats fed on the control diet (white), or the control diet supplemented with 0.4 g/kg phytoestrogens (white spotted), 1.6 g/kg phytoestrogens (grey spotted), or 0.15 g/kg 17β-estradiol (dark grey). The mean values labelled with different letters differed significantly (p < 0.05).Back to article page
