Figure 3. Ultraviolet B irradiation induces mechanical hyperalgesia in wild-type but not PAF-R KO mice.
Columns represent the mean ± SEM (n = 9 mice per group) force of Von Frey hair that caused paw withdrawal before (open columns), 4 hours (gray columns) and 28 hours (black columns) after exposure to 1,500 J m−2 UVB radiation. An asterisk indicates a statistically significant difference from pretreatment levels using a repeated-measures ANOVA with Dunnet’s analysis (*P<0.05).
