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.
