No pathological changes were observed in the hydrophilic petrolatum treatment (control), H-ASD, and ASD group, but marked infiltration of the cells and increased epidermal thickness were observed in the Df, Df + H-ASD and Df + ASD treatment groups. B) Number of mast cells infiltrated in the skin after 4 weeks treatments.
