Figure 3.
Effect of intrarectally administered AITC (1%, 0.05 ml) and PYY knockout (PYY(−/−)) on the mouse grimace scale (ΔMGS) expressed as action units. One-way ANOVA revealed statistically significant differences among the groups (p < 0.001). The data shown are means + SEM, n = 6–7 per group; ***p < 0.001 compared to WT + PO; δδδp < 0.001 compared to PYY(−/−) + PO.
