| Abstract: | Dimensions of sympathetic nerve cells and of their nuclei were studied using various methods of fixation and embedding media, as well as autoradiographic indices of the protein synthesized system of neurocytes in normal rats, and in rats partially sympathectomized at an early age. On the ground of different changes in the average size of neurocytes seen under various methods of fixation, and of decreased labeling intensity of large neurocytes after the injection of the labeled protein biosynthesis precursor there is some reason to believe that large neurocytes may appear in the late reproductive age mainly due to the nerve cell cytoplasm swelling as a consequence of exhaustion of their growth resources. |
