Galphimia glauca and Natural Galphimines Block Schizophrenia-Like Symptoms Induced with Apomorphine and MK-801 in Mice

Table 2

Effects of the oral administration of the methanolic extract of Galphimia glauca (GgMeOH, 25 mg/kg), the Galphimine-Rich Fraction (GRF), and the different galphimines (G-A, G-B, and G-E) on mice with schizophrenic-like symptoms induced by the chronic administration of MK-801 evaluated by means of the Open field test (OFT) for 30 min.

Total crossings, rearings, stereotyped behaviors and grooming bouts, time spent grooming (seconds). MK-801; Vehicle (VEH) = mice with Tween 20 1%; OLZ = Olanzapine; GgMeOH = methanolic extract from Galphimia glauca; GRF = Galphimine-Rich Fraction. ANOVA, Dunnett post-hoc test. Results are means ± Standard Error (SEM). indicates a significant difference from MK-801 at a significance threshold of p<0.05. total crossings = (FD = 9, F (77.65) 2.10, p = 0.0001), rearing = (FD = 9, F (67.26) 2.10, p = 0.0001), grooming = (FD = 9, F (14.23) 2.10, p = 0.0001), time spent on grooming = (FD = 9, F (627.9) 2.25, p = 0.0001).
