Figure 4. — The typical PNA staining was detected in the retinal sections of normal control group. Conversely, no PNA staining was found in the retina sections of the MNU group. The PNA staining could also be detected at the outer segments of EPO treated group. The staining results from the whole mounts agreed well with those from the retinal sections. The PNA staining density of the MNU group was smaller than the normal controls. On the other hand, the PNA staining density of the EPO treated group was significantly larger than the MNU group (#p < .01, for differences compared between animal groups; all the values were presented as mean ± SD).
