Topical Administration of 15-Deoxy-Δ12,14-Prostaglandin J2 Using a Nonionic Cream: Effect on UVB-Induced Skin Oxidative, Inflammatory, and Histopathological Modifications in Mice

Figure 6

UVB irradiation triggers sunburn cell formation that is amenable by topical formulation containing 15d-PGJ2 (TFcPGJ2) treatment. Sunburn cell (white arrows) counts were evaluated using hematoxylin and eosin-stained slices of skin samples collected 12 h after the end of irradiation. Stained slices were examined using light microscopy at 100x magnification. NC: negative control; PC: positive control; uTF: unloaded topical formulation. Bars are of 6 mice per group and are representative of two separate experiments. One-way ANOVA followed by Tukey’s test. versus the negative control group; # versus UVB-stimulated compared groups.
