Change in the relative amounts of mtDNA after I-R.

<p>(A) Cortical tissue samples indicated by dotted line were used for PCR, Western Blot examination, citrate synthase activity assay, and morphology observation. (B) The relative amounts of cortical mtDNA were measured using quantitative real-time PCR in the sham group and the I-R 0 h, I-R 24 h, I-R 72 h, and I-R 7 d groups. The data are expressed as the means±SD. *P<0.05 versus the I-R 0 h and sham groups; #P<0.05 versus the I-R 24 h and I-R 7 d groups.
