Effects of PW-M, PW-H, PW-E and PPWH-7 on DNA fragmentation on cells.

<p>Cells were treated with indicated concentrations of the test agents for 48 hours and genomic DNA was extracted and separated using 1.5% agarose gel electrophoresis. L = DNA ladder; LS = diffused DNA ladder with interspersed smearing; M = 100 bp DNA marker and C = untreated control cells.
