Figure 1. Schematic diagram of ACR and OVA administrations. On indicated days, mice were exposed to 5 ppm ACR for 4 h (squares) and/or 1% OVA in PBS for 30 min (circles). All animals treated with ACR only, OVA only or OVA and ACR were challenged with OVA on Days 19–21. Sample collection occurred on Day 23. Naive mice received no treatment.
