(a, b) Heart sections from mice in the control group and GSPE group exhibiting slight positive P53 reactions (arrows). (c, d) Heart sections from mice in the EST group displaying strong positive reactions (arrows) for P53 expression. (e, f) Heart sections from mice in the GSPE + EST and EST + GSPE groups exhibiting moderate-to-mild positive reactions (arrows) for P53 expression.
