B6 mice were pre-treated with vehicle or MG (50 and 200 mg/kg) prior to seizure induction with picrotoxin (5 mg/kg). a, MG pre-treatment increased the latency to first generalized convulsion. P = 0.0002 by Kruskal-Wallis test. b, MG pre-treatment reduced the duration of generalized convulsions. P = 0.0025 by Kruskal-Wallis test. c, MG pre-treatment reduced the percentage of animals undergoing generalized convulsions. P = 0.0033 by Kruskal-Wallis test.
Data are mean ± SEM. n = 16 vehicle, 8 MG (50 mg/kg), 10 MG (200 mg/kg). * P < 0.05, ** P < 0.005 versus vehicle-treated group as determined by Mann-Whitney U tests.
