CHS responses to oxazolone measured as average ear swelling ±SEM in groups of six mice. (A) Suppression of CHS by UVB radiation, and the reduction in this suppression by UVA exposure both before (UVA+UVB) and after UVB treatment (UVB+UVA). SnPP injection inhibited the protective effect of UVA exposure in both treatment regimes. (B) Suppression of CHS by cis-UCA and the protection from this suppression by UVA exposure both after (cis-UCA+UVA) and before (UVA+cis-UCA) cis-UCA treatment. Injection of SnPP prevented the protective effect of UVA exposure in both treatment regimes, but had no effect on CHS in mice exposed to UVA alone (UVA+SnPP).
