Normal control muscle histochemical reactions and stains. Muscle obtained from an amputation procedure for orthopedic deformity with normal transverse (a) and longitudinal (b) architecture. Normal mitochondrial (c, f, and i), glycogen (d), and lipid (e) content. No inflammatory activity is observed (k and l). Normal checkerboard with type 1 (number 1 in g and h) and type 2 (number 2 in g and h) fiber distribution. l dark dots represent normal neuromuscular junctions (a HE 100x, b HE 400x, c Modified Gomori trichrome 400x, d PAS 400x, e Oil-red-O 400x, f SDH 400x, g ATPase pH 9.4200x, h ATPase pH 4.6200x, i COX 200x, j NADH 400X, k Acid phosphatase 200x, l Nonspecific sterase 200x)
