Northern blot analysis of mRNAs for iNOS, T kininogen, and COX-2. RNAs were isolated from normal rat brains (CTR), BDV-infected rat brains at days 17 and 22 postinfection (BDV), and dexamethasone-treated, BDV-infected rat brains at days 17 and 22 postinfection (BDV+Dex). RNA was electrophoresed in a 1% agarose gel containing formaldehyde, transferred onto nylon membrane, and hybridized with specific 32P-labeled probes as described in Materials and Methods.
