Figure 6.

Muscle section stained with nitroblue tetrazolium (NBT) showing muscle viability. It is clear that control muscle cells are all viable while I/R injured muscle cells lost their viability to variable degrees. The severe loss of viability from 3 h I/R injured muscle cells compared to 2 h I/R injury is evident in this case, but not from all cases (p = 0.14).
