Effects of vitamin C and PD168393 on UVB-induced systemic immunosuppression. C57BL6 mice were fed with standard or vitamin C-enriched chow for 10 days (A) or topically treated with PD168393 (PD) or vehicle (VEH) for 30 min (B) before UVB irradiation (7500 J/m2), CPAF (250 ng, i.p.) or BSA vehicle alone (CON) injections. Delayed type hypersensitivity to DNFB was measured as in Fig. 5. Data are the mean ± SE difference in ear weights from five mice in each group. *, p < 0.05 compared with vehicle control.
