24 hr pretreatment effects of caffeic acid (0, 20.00, 40.00 and 80.00 μM) and glibenclamide (10.00 μM) for 24 hr on ROS production (A) and cell viability (B) in mice isolated pancreatic islets after 24 hr exposure of islets to 320 μg mL^-1 multi-walled carbon nanotubes (MWCNTs), (n = 7). Results are expressed as mean ± SEM. Difference between control and other groups was significant at p < 0.05 (a) and p < 0.01 (a*). Difference between MWCNTs and other groups was significant at p < 0.05 (b) and  p < 0.01 (b*). CA: Caffeic acid, GLB: Glibenclamide
