Data are expressed as the mean ± SD (n = 3). The statistical analysis was performed at p < 0.05. *, ^#, and ^@ indicate significant differences. Regarding PLX188 NCs: * vs. 0.1% w/v; ^# vs. 0.15% w/v; ^@ vs. 0.3% w/v. Regarding CS/PLX188 combinations: * vs. 0.02/0.15 (% w/v); ^# vs. 0.04/0.15 (% w/v).
