Demonstration of Nicotinamide Adenine Dinucleotide Diaphorase (NADH) in different groups of rats.

<p>Panel A, photomicrographs of the masseter muscle of rats. 200x magnification. Magnification bars: 100 μm. Panels B, C and D means the percentage of Light Fibers (B), Intermediate Fibers (C) and Dark Fibers (D) in different groups.</p

Quantification of Reactive Oxygen Species (ROS) in different group of rats.

<p>Panel A, photomicrographs with fluorescent labeled for ROS of masseter muscle of rats. 200x magnification. Magnification bars: 50 μm. Panels B, C and D means de fluorescence intensity of ROS in differente groups. Fig 3B: P < 0.05, NO+C group <i>vs</i> E+C, NO+A and E+A groups; and P < 0.05, E+A group <i>vs</i> E+C group (Tukey-Kramer test).</p
