Relative HO activities in ocular tissue from eyes harvested in part II experiments (group II). Results are shown for five groups including: nonischemic retinas from vehicle-treated rats (Control Baseline) and I/R-injured retinas from vehicle- (Control Ischemia), α-MSH- (MSH Ischemia), SnPP + α-MSH- (SnPP + MSH Ischemia), and SnPP-treated rats (SnPP Ischemia). Activity of the enzyme in ocular tissue of an aforementioned group is shown as percentage of bilirubin production by a particular group relative to control baseline eye values with SEM
