Mean total ganglion cell count ±SEM, mean dissector number, section thickness, number of sampled sections, coefficient of error (CE), and coefficient of variation (CV) of stereological analysis between subjected to ischemia/reperfusion and treatment groups in the rodents. The stastical difference between all the groups is significant ; between C and IR p<0.0001, C and BEV p<0.01 and IR and BEV p<0.01. The neurodegenerative effects of IR and the neuroprotective effects of BEV were examined by inducing 45 min of an ischemic insult and following a reperfusion of 48 h. There were 203.712±27.749 cells in the RGCL in the control group and 131.133±16.025in the IR group, showing a 36% decrease in living cells as a strong sign of neurodegeneration (p<0.0001). When we compared the cell numbers in the BEV group 173.289±5.336to the IR group 131.133±16.025we clearly saw there was a higher number of cells in the BEV group, and the difference was statistically significant (p<0.01). This is a strong clue that BEV has a neuroprotective effect in the event of ischemia.
