Erythema and oedema scores for DNCB-induced rashes treated with various nanocrystalline silver-derived solutions. Daily average erythema and oedema scores are shown in Panels A and B, respectively, for negative controls (pigs without rashes treated with distilled water-soaked dressings), and for pigs with DNCB-induced contact dermatitis treated for three days with distilled water (positive controls) or nanocrystalline silver-derived solutions with starting pHs of 4, 5.6, 7, or 9. The statistical analyses, which were performed using one-way ANOVAs with Tukey-Kramer Multiple Comparisons post tests, are shown in Table 1. Error bars represent standard deviations.
