Previous neurophysiological experiments have shown that in rats with an acute myositis of the gastrocnemius-soleus muscle, dorsal horn neurones exhibit an increase in responsiveness to peripheral stimulation and in background activity. The present study investigated the possible correlation between changes in NADPH-diaphorase activity and neurophysiological alterations. In the animals used for the electrophysiological experiments the diaphorase activity in sections of the lumbar spinal cord was determined with the NADPH-nitroblue tetrazolium reaction. The main findings was a massive reduction in the number of diaphorase-positive cells in the superficial dorsal horn in animals with a myositis. The staining intensity in the remaining neurones was unchanged. The results are interpreted as indicating that the myositis in addition to the surgical operations represents a supramaximal input to the dorsal horn causing neurotoxic effects in diaphorase- positive neurones.
