[Myelin-like structures in heart muscle cells following exposure to adrenaline].
The state of the muscle cells of the heart was studied experimentally in 36 albino rats the next day after a single administration of adrenaline hydrochloride (3mg/kg), intramuscularly into the hip. Areas of overcontraction and overextension of myofibrills, numerous myelin-like figures not infrequently containing mitochondria and glycogen, drops of lipids were observed by electron microscopy. It is suggested that the affecting action of adrenaline is expressed through the activation of lipolysis which results in dissociation of the protein-lipid components of the mitochondrial membranes, accumulation of fatty acids in the cytoplasm and resynthesis of the new unusual membranous formations.
