Table 4 Changes in Membrane Integrity (LDH Release) in IEC-18 and AGS Cells in Response to Oxidants.

From: Dietary antioxidants protect gut epithelial cells from oxidant-induced apoptosis

Treatment IEC-18 Cells AGS Cells
H2O2 -12.0 ± 0.8 -8.2 ± 1.6
Peroxynitrite -3.7 ± 1.5 1.4 ± 2.0
DPPH 33.1 ± 2.7* 8.0 ± 3.6
  1. Results are presented as a percent change from control values, Mean ± SEM, n = 4 per group. The increase in LDH release evident in DPPH treated IEC-18 cells (*P < 0.05 vs. control) was significantly reduced by cat's claw (11.6 ± 6.7%) or green tea (11.3 ± 3.9%), P < 0.05 compared to DPPH treatment alone, but not by vitamin C (29.3 ± 6.0%).
