Figure 1From: Degeneration of spinal motor neurons by chronic AMPA-induced excitotoxicity in vivo and protection by energy substratesProgressive alterations of the rear limbs induced by AMPA and protection by energy substrates. Representative posterior views of the rear limbs (C, contralateral; I, ipsilateral) and hind paw footprints (red, ipsilateral; black, contralateral) at the initial (day 1), the middle (day 4) and last day (day 7) of treatment. The AMPA-induced progressive alterations were prevented by pyruvate and βHB but not by ascorbate and GEE alone (not shown) or in combination (antioxidant mixture).Back to article page
