Electron Microscopic Observations of a Dense, Irregularly Banded Material occurring in Some Porcine Muscle Fibres

Abstract

A PREVIOUS communication1 described the electron microscopic changes occurring in porcine muscle which had undergone an extremely rapid rate of post-mortem anaerobic glycolysis. At that time no evidence was found of the dense clumps across the muscle fibres which Bendall and Wismer-Pedersen2 postulated were denatured sarco-plasmic proteins resulting from rapid glycolysis at a high-temperature post-mortem. Since then we have observed a dense, irregularly banded substance in porcine muscle, but we have interpreted its occurrence in a different manner.
