ABSTRACT
To determine whether ginkgo biloba extract(GBE)combined with dexamethasone(DEX)plays a role in the treatment of allergic rhinitis-related olfactory dysfunction using an animal model.Six week old BALB/C mice were sensitized and challenged with ovalbumin.30 sensitized mice were divided into three groupsGroup 1 was given high-dose GBE and DEX(n=10);Group 2 was given low dose GBE and DEX(n=10);Group 3 was given DEX alone(n=10).We assessed the histology of the olfactory mucosa and serum IL-4,IFN-γ,and caspase 1.A significant higher fraction of mice in group 1 could find the food pellet within300 scompared to group 3(<0.05).Caspase-1 levels improved during the second week compared with the first week in each group.IFN-γlevels were significantly lower during the second week compared with the first week(<0.05,all).IL-4 levels also were significantly lower during the second week compared with the first week in all groups except those receiving DEX alone.IFN-γ/IL-4 levels in each group were significantly lower during the second week compared with the first week(<0.05,all).In this animal model of allergic rhinitis-related olfactory dysfunction,the addition of ginkgo biloba extract to dexamethasone have a better anti-inflammatory effect,which can partly improve the therapeutic effect on olfactory dysfunction caused by allergic rhinitis.
