Isoliquiritigenin Attenuates Anxiety-Like Behavior and Locomotor Sensitization in Rats after Repeated Exposure to Nicotine

Figure 7

Effects of intra-NaccSh infusion of ISL on repeated NIC-induced locomotor sensitization. Similar to the oral and the ICV treatment, the intra-NaccSh administration of ISL blocked the expression of repeated NIC-induced locomotor sensitization, which was abrogated by a post-ISL infusion of either t-BOOH or NMDA into the NaccSh. All data are expressed as a mean ± SEM (n = 6). S: saline; ISL: isoliquiritigenin; NIC: nicotine; MRS: modified Ringer’s solution. vs. S/NaccSh-MRS/MRS/S group; vs. NIC/NaccSh-MRS/MRS/NIC group; vs. NIC/NaccSh-ISL/MRS/NIC group (one-way ANOVA followed by Newman–Keuls post hoc test).
