[Vesicular transport in heart muscle tissue].
Myocardial vesicular transport has been examined, using intravital perfusion fixation staining with glutaraldehyde and ruthenium red. De novo capillary endothelial and plasmatic membrane formation of microvesicles has been demonstrated, and vesicular transport has been followed through its various stages. Myocardial vesicular transport is purposeful movement from capillary lumen through the endothelium (endocytosis-exocytosis) to intercellular space and therefrom to cardiomyocytes by means of endocytosis. Approximate scale of vesicular transcapillary transport is estimated at 7 mg protein per minute per 100 g wet myocardial tissue, and presupposes a fairly high cardiomyocyte endocytosis level.
