Generation of ROS by liver subcellular fractions obtained from animals subjected to PH and treated with α-tocopherol and/or putrescine. Results are the mean ± SE of arbitrary units of fluorescence (normalized) per mg−1 of protein for 5 individual observations per experimental point from total homogenate (panel A), cytoplasmic (panel B), and plasma membrane (panel C) fractions. Symbols for each experimental group are indicated at the top of the figure. Statistical significance as pointed out in Fig. 1
