Immunohistochemical detection of IL-8 in biopsies of DNCB-induced rashes treated with various nanocrystalline silver-derived solutions. Immunohistochemical staining scores for IL-8 are shown after 24 h (A) and 72 h (B) of treatment of negative controls with distilled water, and DNCB-induced porcine contact dermatitis rashes with distilled water (positive controls), or nanocrystalline silver-derived solutions generated at starting pHs of 4, 5.6, 7, or 9. Statistical analyses, which were performed using one-way ANOVAs with Tukey-Kramer Multiple Comparisons post tests, are shown in Table 4. Error bars represent standard deviations.
