Figure 2. Muscle mass recovery of regenerating tibialis anterior muscle in rats.

Figure 2

Both sham and bupivacaine-injured muscles were collected at days 0, 2, 5, 14, and 28 post-injury, and weighed. Muscle weights are presented for injured (A) and sham (B) muscles. A recovery index, as the percentage of injured relative to sham values, was calculated and presented for muscle mass (C). Values are mean ± SEM (n = 7-8 rats per dietary group/time point). Groups bearing different letters for a given time point are significantly different (p≤0.05). C, casein; CP, cod protein; C+, casein supplemented with L-arginine, glycine, L-taurine and L-lysine.
