Effect of TMP on expression of Bcl-2/Bax proteins in spinal cord at the 48th hour reperfusion. Western analysis was carried out as described under Methods and the blots are shown in the upper right hand corner. Lane 1 represents sham group; Lane 2 represents vehicle control group; Lane 3 represents TMP group. The bars depict densitometry analyses of Western Blots from four independent experiments. Ischemia reperfusion obviously reduced Bcl-2 expression and increased Bax expression compared with the sham group. *P < 0.01, vs sham group; **P < 0.01, vs control group.
