URB597, but not WIN restored paired pulse facilitation in rats subjected to MDA acute kindling. (a) Representative DG field potential responses after paired stimulations 20, 25, 110 and 600 ms apart in vehicle, WIN 2 mg/kg, and URB597 1 mg/kg before MDA induction (dark traces) and at the end of 4 hours stimulation at frame 24 (coloured traces). Scale bar = 2 mV and 5 ms. MDA acute kindling impaired paired pulse facilitation in vehicle (b), WIN (c) and AM251 (e) and AM251 + WIN (f) groups. Conversely, administration of URB597 was able to prevent the MDA-induced alteration of paired pulse facilitation (d) and this effect was blocked by the pre-administration of AM251 (g). Drugs were injected one hour after MDA induction at stimulus n. 6. Graphs represents the mean ratios at each interpulse interval before (pre-drug) and after administration of drugs. One-way ANOVA for repeated measures followed by Bonferroni’s post hoc test; *p < 0.05 and **p < 0.01 versus pre-MDA condition.
