Outline of Final Research Achievements

In this study, we evaluated the effects of exercise and NSAIDs, especially aspirin on oral sensitization to an egg-white allergen, ovalbumin (OVA) as well as OVA absorption, in rats. In OVA-sensitized rats, plasma concentrations of OVA and a paracellular marker, FD-40 were significantly higher than those in unsensitized rats after oral administration. Aspirin increased oral absorptions of OVA and FD-40 via the paracellular pathway, and exhibited a lower rectal temperature in OVA-sensitized rats. Sodium cromoglycate ameliorated these aspirin-facilitated absorptions and allergic reactions in a dose-dependent manner. Aspirin also exhibited higher plasma levels of OVA-specific IgE and IgG1 than those in control at 6 and 8 weeks after initiation of oral sensitization. In conclusion, facilitation of OVA absorption via paracellular pathway due to impairment of intestinal barrier function by aspirin is considered to be one of the reasons of enhanced oral sensitization with OVA by aspirin.
