The material from the myocard of rabbit ventricule, treated with 10% Formalin alcohol solution more than 24 hours, not stained and mashed in the agar mortar for 30 to 60 minutes very slowly was examined under the electron microscope.
The finest fibrous elements as seen with the electron micrographs are the protomyofibrils, ranging in width from about 20 to 50mμ and in which dense particles a little irregularly arranged. Electron micrographs show that myofibrils about 1μ in width possess the beautiful striated figures.
The smallest particles of the sarcoplasm were observed as about 15 to 30mμ granules, and various granules, ranging 50 to 100mμ, 500 to 1000mμ in size, tied with protoplasmic filaments one another or aggregated in several numbers were too revealed.
