Transneuronal Degeneration in the Visual Pathway of Rats following Acute Retinal Ischemia/Reperfusion

Figure 1

The mean density of RGC retrograde labeled by CTB ( μm). (a) I/R-2 h to 14 d: representative photomicrographs were taken at high magnification of rats euthanized 2 hours, 6 hours, 12 hours, 1 day, 3 days, 7 days, and 14 days post-RI/R injury. (b) MD-RGCs: I/R-1 d, I/R-3 d, I/R-7 d, and I/R-14 d (rats euthanized 1 day, 3 days, 7 days, and 14 days post-RI/R injury) were less than those in the control group (). I/R-2 h: rats euthanized 2 hours post-RI/R injury; I/R-6 h: rats euthanized 6 hours post-RI/R injury; I/R-12 h: rats euthanized 12 hours post-RI/R injury; I/R-1 d: rats euthanized 1 day post-RI/R injury; I/R-1 d: rats euthanized 3 days post-RI/R injury; I/R-7 d: rats euthanized 7 days post-RI/R injury; I/R-14 d: rats euthanized 14 days post-RI/R injury. indicates that there were statistical differences when compared with the control groups. indicates that there were significant statistical differences when compared with the control groups.
