a Photomicrographs show the effect of D. sephen venom on: (i) intracellular ROS generation; (ii) mitochondrial membrane potential and; (iii) apoptotic morphology changes in HeLa cells. b Effect of D. sephen venom on: (i) intracellular ROS generation; (ii) mitochondrial membrane potential and; (iii) percentage of apoptosis in HeLa cells. Values were given as mean ± SD of six experiments in each group. Bars not sharing a common letter differ significantly (p < 0.05) from control (DMRT)
