Astroglial response in the striatum. Photomicrographs of representative sections of the ipsilateral (A, B) and contralateral (C, D) striatum of an animal receiving COXIB at 21 days. E, F) Bar graphs showing the GFAP positive density in the striatum. E) Astroglial density was significantly higher in the lesioned striatum (P < 0.01), with no significant differences between treatment groups. F). Scale bar: 25 μm.
