[Unusual transformation of myosin filaments in the frog skeletal muscle fiber].
An ususual alteration of A-band of the frog fast skeletal muscle fiber in the course of the speading (Zenker's) necrosis in calcium-free medium is described, Myosin filaments in distal parts of A-band stick together to from ribbons approximately 0.5 mkm long. The ribbons separate from the central portion of A-band and displace into I-bands up to Z-line. On transverse section, structure of I-bands looks similar to that of vertebrate smooth muscle as reported by Small and Squire (1972).
