Figure 2
Lung histopathological sections of BALB/c mice stained with haematoxylin/eosin. Mice were immunised on days 0 and 7 with sc. injections of 4 μg OVA/1.6 mg alum. On days 14 and 21, the mice were challenged by in. with 10 μg OVA. The experiments were conducted 24 hours after the last challenge. Two magnifications were given (400 and 100x) to the clean control (a), OVA-immunised (b), DEXA-treated (c), and PHE-treated groups at 50 mg/kg (d) or 200 mg/kg (e). Arrows indicate areas of inflammation.
