[Basic changes in neurons in the peripheral regions of the human nervous system during pathologic processes (electron microscopic study)].

Compensatory-adaptational and reparative reactions were studied in bodies, processes, receptors and synapses of the human peripheral nervous system and in the innervated substrate (myocardium, kidney, liver) by means of electron microscopy. An extreme increase of the electron density of macromolecular protein formations of specific elementary particles was revealed, in particular, in the outer layers of the hypertrophid mitochondria cryst membranes at 50000.000 magnification. These particles are considered as mitochondria precursors.
