Effect on hepatic ROS production. ESR signal intensity of CMH-detectable ROS in liver of rats fed diets with either soybean oil or salmon oil with various vitamin E concentrations. (A) Bars represent total ROS using the spinprobe molecule CMH and are means ± SD from 8 animals per group; ^a,b values with different superscript letters differ significantly (P < 0.05). (B) Representative ESR spectra of samples are shown for 1 animal per group (A, diet with soybean oil and 25 vitamin E/kg; B, diet with soybean oil and 250 vitamin E/kg; C, diet with soybean oil and 2500 vitamin E/kg; D, diet with salmon oil and 25 vitamin E/kg, E, diet with salmon oil and 250 mg vitamin E/kg; F, diet with salmon oil and 2500 mg/kg vitamin E)
