^*Results are the mean ± SD of values from 18 skin sites, except for day 1 where n = 24.

^†Scores: 1, very slight erythema; 2, well-defined erythema; 3, moderate to severe erythema; 4, severe erythema.

^‡Significantly different from mean air control value.

^§Significantly different from mean low dose value.

^¶Scores: 1, very slight edema; 2, slight edema; 3, moderate edema; 4, severe edema.
