Time (h) Control Peptide + Zn2+ Peptide + Zn2+ + DTPA 24 h 40 ± 3 56 ± 2* 38 ± 4# 48 h 43 ± 3 185 ± 18* 44 ± 3# The cells were treated with THF (10-10 M), Zn2+ (10-8 M) or DTPA (5 μM) for 24 and 48 h. The value represents the mean ± SD of the mean channel fluorescence (540 nm) of 3 independent experiments. *p<0.01 compared with the control group; #p<0.01 with peptide + Zn2+
