Unilaterally lesioned rats were injected (i.p.) with PG01042 (●, 10 mg/kg) followed immediately with a constant dose of SKF 81297 (0.05 mg/kg, s.c.). The percent of the mean total AIMs score ± S.E.M. (n = 12) relative to vehicle control (○) as a function of the dose of PG01042 is shown. The mean reduction ± S.E.M. for the normalized total AIMs values using PG01042 was 10 mg/kg, 8.0 ± 6.8% reduction but significance was not achieved (F(1,22) = 0.72, p = 0.40).
