Itch, a skin sensation that provokes the desire to scratch, accompanies various skin diseases such as atopic dermatitis. In present study, we investigated the anti-pruritic effect of fish oil on scratching behavior mouse models induced by compound 48/80, a mast cell degranulator. Fish oil or diphenhydramine, histamine H1 receptor antagonist, was orally administrated 1 h before subcutaneous injection of compound 48/80. The number of scratching was counted for a period of 20 min after the injection of compound 48/80 and fish oil inhibited the scratching number in a dose-dependent manner, but with potency less than that of diphenhydramine. Also, fish oil suppressed the serum immunoglobulin E (IgE) and histamine induced by compound 48180. Especially, the inhibitory effect of fish oil on histamine release was actually stronger than that of diphenhydramine. Therefore, these results suggest that fish oil may be an effective source for improving allergic symptom of atopic dermatitis.
