Fig. 4.
Optical density of SDH activity staining (A) and spatially integrated SDH activity [FCSA × SDH activity, in arbitrary units (au); B] in the deep (oxidative) and superficial (glycolytic) region of the plantaris muscle in saline-treated (CON; n = 11) and monocrotaline-injected (MCT; n = 12) animals. *P < 0.05 between regions; #P < 0.05 between conditions. ′Total′ is the weighted average for all fibers. Type I fibers were only isolated in the superficial region in 4 and 5 rats (in CON and MCT, respectively).
