Chronic effects of β-FNA on LPS-induced anxiety- and sickness-like behavior in male C57BL/6J mice. Micro-osmotic pumps containing saline or β-FNA (42 μg/d) were surgically implanted and dispensed at a flow rate of 0.5 μL/h for 7d. 6d post-surgery, mice (n = 7–8/group) were injected (i.p.) with either 25 μL saline control or LPS (0.83 mg/kg). Behavioral tests were administered 24 h later, and termination followed immediately after. Data are presented as mean ± SEM. A Time in closed arms: Two-way ANOVA indicated significant main effect of LPS (p < 0.01), no significant main effect of β-FNA (p = 0.71), and a significant interaction of main effects (p < 0.0001) on time spent in the closed arms of the EPM (n = 5–6/group). Pairwise comparisons were assessed using Fisher's LSD test; bars with letters in common indicate data are not significantly different (p > 0.05). B Time spent motionless: Two-way ANOVA indicated significant main effect of LPS (p < 0.005), no significant main effect of β-FNA (p = 0.12), and a significant interaction of main effects (p < 0.001) on time spent motionless in EPM (n = 5–8/group). C Total distance moved: Two-way ANOVA indicated significant main effect of LPS (p < 0.001), no significant main effect of β-FNA (p = 0.26), and a significant interaction of main effects (p < 0.05) on total distance moved in EPM (n = 6–8/group). D Time spent in a contracted position: Two-way ANOVA indicated significant main effects of LPS (p < 0.0001) and β-FNA (p < 0.0005), as well as a significant interaction of main effects (p < 0.0001) on time spent in a contracted position (n = 6–7/group). Pairwise comparisons were assessed using Fisher's LSD test; bars with letters in common indicate data are not significantly different (p > 0.05)
