Immunoreactivity of ET-1, ET_A and ET_B in retinas with different treatment of LBP and PBS at day 14 post COH. The immunoreactivity of ET-1 and ET_B was decreased whereas ET_A immunoreactivity increased in COH+LBP group (B, D, F), when compared with COH+PBS group (A, C, E). G-L were enlarged pictures of GCL from A-F. Scale bar: 20 μm, n = 3.

COH: Chronic ocular hypertension; PBS: phosphate-buffered saline; LBP: Lycium barbarum Polysaccharides; COH+PBS: COH with feeding PBS group; COH+LBP: COH with feeding LBP group; GCL: ganglion cell layer; IPL: inner plexiform layer; INL: inner nuclear layer; ONL: outer nuclear layer.
