case_images: Light microscopy of the left vastus lateralis ((a), resin; (b)-(f), cryostat). (a) Vacuoles filled with polysaccharide material (PAS, x 40); (b) vacuoles stained positively for acid phosphatase reaction (x 20); (c) ATPase histochemistry at pH 4.3 revealed selective atrophy of type 1 fibers (x 40); (d) vacuoles are present predominantly in type 1 fibers (x 40); (e)-(f) atrophic fibers containing numerous nemaline bodies (Gomori trichrome, x 100).

case_images: Furthermore, many of these atrophic fibers (7% of all fibers contained in transverse sections) displayed numerous, discrete, deposits of basophilic material, located centrally within the fiber cytoplasm or, in some instances, in a subsarcolemmal position (Figure 2).
case_images: By EM, nemaline bodies are oriented consistently with the longitudinal axis of the fibers and they are composed of myofibrillar material in apparent continuity with Z-bands ((a), x 28.000; (b), x 45.000).
