[Histochemical evidence of aminotransferases. II. Localization of aminotransferases in the medulla spinalis and metencephalon of the rat (author's transl)].
The cytochemical and topochemical localization of 10 aminotransferases have been studied in a serial slices through the spinal cord, medulla oblongata, pons and cerebellum of the rat. In the gray matter a high enzyme activity was observed. The reaction product was localized in the cells and the surrounding neuropil. The cell nuclei were found negativ. In some nuclei aminotransferase activity was higher in the neurons than in the neuropil. In the other nuclei there were no recognizable differences in staining intensity between the neurons and the neuropil. The nerve cells of spinal cord and reticular formation, nuclei n. hypoglossi and n. facialis, nucl. vestibularis lateralis and the Purkinje cells exhibited particularly high aminotransferase activity.
