Fig. 7From: The role of vasoactive intestinal peptide (VIP) in atropine-related inhibition of the progression of myopiaProtein and mRNA expressions of retinal VIP in guinea pig (mean ± SD). Compared with the NC group, the mean optical density of retinal VIP protein and VIP mRNA positive cells in the FDM group were significantly up-regulated (P < 0.01). In contrast, those in the FDM + AT group did not change significantly (P > 0.05)Back to article page
