Fig. 4. Spinal immunoreactivity to glial fibrillary acidic protein after 7-day treatment with intrathecal meloxicam or saline started 7 days after spinal nerve ligation. Prominent astrocytic activation was observed in both the saline ( A ) and the meloxicam group (320 μg · kg−1· day−1[ B ] and 32 μg · kg−1· day−1[ C ]). Bar = 100 μm.
