“…Since glycogen acts only as a primer of phosphorylase activity, it is possible that catalytic amounts of glycogen may be present, but only in quantities which the PAS technique may not be capable of demonstrating. Other factors, such as the activity of the muscle fibers at the time of quenching, may influence phosphorylase activity more than glycogen content (Mommaerts et al, 1975). Until the causes for the variations in PAS and phosphorylase staining are defined, we feel that these two techniques offer little practical benefit in fiber typing.…”

“…However, it is apparent that definite interspecies differences exist in normal muscles. Many reports have appeared that pertain only to the study of basic muscle biology, but an increasing number of studies are related to the application of histochemical techniques to the study of diseased muscle (Dubowitz and Brooke, 1973;Stern et al, 1975;Spencer and Zorab, 1976;Spencer and Eccles, 1976;Meijer et al, 1977). Data available on human fiber types far exceed those pertaining to nonhuman primates.…”

“…The method is a modification of that published by Rosenblatt et al (1987), which is in tum a combination of two previously reported techniques (Meijer and Vloedman, 1980;Meijer, 1970). The histochemical bases of the staining reaction are those reported by Meijer (1970) and Meijer and Vossenberg (1977) and quoted by Rosenblatt et al (1987). Briefly, ATP present in the incubation medium is hydrolyzed by capillary endothelial ATPase, which is revealed by the deposition of lead sulfide.…”

“…Type II fibres were further classified as Type II A if inhibition was complete with pH 4.5 pre-incubation, Type II B if pH 4.3 pre-incubation was required for complete inhibition and Type II C if inhibition was not complete unless pre-incubation pH was less than 4.0. These characteristics have been useful in classifying muscle fibres of limb skeletal muscles of humans (Meijer & Vossenberg, 1977;Brooke & Kaiser, 1970b;Askansas & Engel, 1975) and laboratory animals (Samaha et al, 1970;Guth & Samaha, 1972;Khan, 1977).…”
