Sci.. 2007;48(1):361-367. doi:10.1167/iovs.06-0510 Figure Legend: Administration of aminoguanidine inhibited capillary cell death after retinal I/R in rats. (A) An example of TUNEL-positive capillary cells (red arrows) in the retinal vasculatures of injured retinas at 7 days after I/R by trypsin-digested method (top), PASH staining of the same area (bottom) showed condensed or fragment nuclei of TUNEL-positive cells (red arrows). (B) Inhibition of retinal I/R-induced capillary cell death by pretreatment with aminoguanidine. (n = 3–5 in each group; *P < 0.05 compared to control retinas; **P < 0.05 compared to I/R-injured retinas).
