FIGURE 9.

Electron microscope ultrastructure of rat retina. The ultrastructure of retina in model group was severely damaged. In the model group, the photoreceptors showed an increase in the spaces between their OSs and those between their membranous disks; Swollen mitochondrias (red arrow) and autophagosomes (red circle) were seen in GCL, and swollen synapses (yellow arrow) were seen in IPL and OPL. In MMXY-H group, the photoreceptors showed marked reduction in the spaces between their OSs and those between their membranous disks compared to model group, mitochondrial swelling was rare in GCL, and there was no obvious synaptic swelling in IPL and OPL. Red arrow, swollen mitochondria; Yellow arrow, Swollen neuron synapse; Red circle, autophagosomes; Yellow circle, glycogen granules; Red asterisk, Golgi; Yellow asterisk, lysosome; Yellow well, Poly ribosome; Red triangle, rough endoplasmic reticulum; Yellow triangle, smooth endoplasmic reticulum; Yellow box, endoplasmic reticulum swelling; Red box, interstitial swelling.
