  • a Values are expressed as mean ± SEM. OA, OVA-challenged mice; SAL, saline-challenged mice. *, Significantly different from saline-challenged mice. Among OVA- and saline-challenged groups, no significant difference was observed in the number of total cells, the number of mononuclear cells, or the number of neutrophils.
