Comparative effects of glibenclamide and riluzole on spontaneous rearing, accelerating rotarod and grip strength. A: Serial measurements of the time (mean±S.E.) spent in spontaneous rearing in rats administered riluzole (empty triangles) or glibenclamide (filled circles); 13 rats per group; *Pb 0.05; **Pb 0.01; the abscissa gives time in days (d) or weeks (w). B: Performance on the accelerating rotarod, measured 6 weeks after impact, in rats administered riluzole (RIL) or glibenclamide (GLIB), as indicated; 13 rats per group. C: Grip strength, measured 6 weeks after impact, for the contralateral forepaw (CONTRA), the ipsilateral forepaw (IPSI), and both together (BOTH), in rats administered riluzole or glibenclamide, as indicated; 13 rats per group. In all cases, the drugs were administered beginning 3 h after impact and were continued for 1 week.
