THE INTERMEDIATE MUSCLE FIBER OF RATS AND GUINEA PIGS
Abstract
The soleus, plantaris and gastrocnemius muscles of 60 Sprague-Dawley rats and 70 Hartley guinea pigs were studied histochemically. In the plantaris and gastrocnemius muscles, myosin adenosine triphosphatase activity differentiated intermediate fibers from red and white fibers as determined by malate dehydrogenase and succinate dehydrogenase and reduced nicotinamide adenine dinucleotide diaphorase activities. Contrary to what is commonly reported, red fibers could not be distinguished from white fibers on the basis of myosin adenosine triphosphatase activity as is commonly reported. The intermediate fiber was characterized by minimal menadione-mediated α-glycerophosphate dehydrogenase, phosphorylase and myosin adenosine triphosphatase activity and moderate malate dehydrogenase and succinate dehydrogenase and reduced nicotinamide adenine dinucleotide diaphorase activities. It is suggested that fibers with intermediate oxidative enzyme activity are physiologically slow, white fibers are fast and red fibers are moderately slow or even fast contracting fibers.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
