Plasma FSH level was significantly elevated in I/R group compared to negative control group (2.12 ± 0.17 versus 1.76 ± 0.03, P < 0.02); however nonsignificant changes were observed in plasma FSH in ischemia only, Gingko biloba treated I/R, and Gingko biloba supplemented groups compared to the negative control group. This evidence concerns the gene BRD2 and ischemia.
