Figure 4 Immunohistochemical Microscopy of p70S6 Kinase at the BZ in Different Treated Rats

Positive staining for phospho-p70S6 kinase (p70S6 kinase) (magnification 200x) (brown color) in myocytes is significantly higher in groups treated with vehicle (B), glibenclamide (E), and a combination of nicorandil + glibenclamide (F) and pinacidil + glibenclamide (G) than those in sham (A), nicorandil- (C), pinacidil- (D), rapamycin- (H), rapamycin + nicorandil- (I), and rapamycin + pinacidil–treated rats (J). The line length corresponds to 200 µm. BZ = border zone.
