Abbreviations: OB, olfactory bulb; RT-PCR, real-time polymerase chain reaction. The amount of COX2, IL-1β, L1G1, OGG1, and XPA cDNA in each sample was normalized to the amount of GAPDH cDNA, yielding an index (molecules per attomol GAPDH rRNA) proportional to the relative abundance of each mRNA in each sample. Values are expressed as molecules/attomol GAPDH. Values are mean ± SD
