Abstract:
OBJECTIVE:To explore the prophylactic effect of Budesonide on the expression of IL-4,IL-5 in nasal mucosa in model of minimal persistent inflammation of allergic rhinitis in rats.
METHOD:Eighty SD rats were randomly divided into allergic rhinitis group (A group), experimental (B group), control group (C group) and negative control group (D group). A group was made for model of allergic rhinitis. B and C group were made for model of the lightest persistent inflammatory response. After the models were established, half of rats in the A group, B group, C group and D group were executed, and EOS infiltration and the expression of IL-4, IL-5, ICAM-1 were observed in nasal mucosa. The remaining rats of B group were given budesonide (64 microg/side/time, twice/day) treatment for 2 weeks. A, C, D group were given nasal spray with normal saline for 2 weeks. After that A, B, and C groups were stimulated with 1% OVA daily for one week, D group were given nasal spray with normal saline. All rats were executed after excitation, EOS infiltration and IL-4, IL-5 expression were observed.
RESULT:After the drug treatment, B group only had a small amount of mucous EOS infiltration and had no significant difference with D group, but in A and C group EOS had heavy infiltration. Gray value of the IL-4 positive areas in B group were significantly different compared with A and C group (P < 0.05), A group and C group had no significant difference (P > 0.05). Distribution of IL-5 positive signals was similar with that of IL-4.
CONCLUSION:Budesonide MPI application could significantly inhibit the allergic.
