Total receptor expression was assessed in SHAM and PCS treated or not with sildenafil (SILD). Total amount of the alpha 1 subunit of GABAA receptor (A-B), NR1 and NR2a subunits of NMDA receptors (C-D) and GluR1 and GluR2 subunits of AMPA receptors (E-F) in hippocampus of PCS and SHAM rats treated or not with sildenafil. Experiments were the same shown in Fig. 5 but only the samples incubated in the absence of BS3 (total amount) are presented. The intensities of the bands were quantified and expressed as percentage of control rats. Values are the mean ± standard errors of 14–18 rats per group. Values significantly different from control rats are indicated by asterisks and from PCS rats by a. *p < 0.05; ^a p < 0.05; ^aaa p < 0.001
