A comparison with the axonal reaction

Abstract
Several oxidative enzymes were demonstrated by histochemical methods in spinal motor neurons of patients with Werdnig-Hoffmann disease and of control cases matched for age. Motor neurons of patients with Werdnig-Hoffmann disease showed no evidence of deficiency of any of the enzymes studied. Chromatolytic nerve cells in patients with Werdnig-Hoffmann disease showed an increase in activity of several enzymes. This increase was most striking with the TPNH diaphorase reaction. The histochemical changes in chromatolytic cells in patients with Werdnig-Hoffmann disease resembled the changes observed following axon section in experimental animals.
