Figure 7From: Study of the nitric oxide system in the rat cerebellum during agingMicrophotographies of iNOS immunoreactivity in the cortex and nuclei of rat cerebellum rostro-caudal sections. Panels A and C: adult rat. Panels B and D: old rat. Only Purkinje cells soma (arrows) seems to be positively marked in the cerebellar cortex when using an antibody against iNOS in both experimental groups (A, B). Marked neurons (asterisks) are observed in the dentate nucleus (dt) of old rats (D) but not in adult rats (C). g: granular layer; m: molecular layer; p: Purkinje cells layer; wm: white matter. Scale bars: A-D, 100 μm.Back to article page
