Fig. 3From: Alteration of colonic excitatory tachykininergic motility and enteric inflammation following dopaminergic nigrostriatal neurodegenerationRepresentative pictures of GFAP, SP, and NK1 immunostaining of cross-sections from full-thickness rat colonic specimens from controls or 6-OHDA animals at weeks 4 and 8. Scale bar = 50 μm. Column graphs display the quantitative assessment of GFAP and SP immunostaining in myenteric ganglion area and NK1 receptors in longitudinal muscle area. Each column represents the mean value of PPP ± S.E.M. value (n = 8). *P < 0.05. CM circular muscle, LM longitudinal muscleBack to article page
