Abstract

Background: Oxidative stress is defined as the condition in which balance between the synthesis and detoxification of reactive oxygen species in cells is disrupted. This research explored the effects of intermittent and prolonged fasting on malondialdehyde (MDA), carbonyl, reduced glutathione (GSH), and specific activity of catalase as biomarkers for oxidative stress in hearts, brains, and kidneys of New Zealand White (NZW) rabbits. Methods: Fifteen NZW rabbits were divided into control, intermittent fasting (IF), and prolonged fasting (PF) groups. The controls were fed ad lib. IF and PF groups were fasted for 16 and 40 hours, respectively, followed by eight hours of non-fasting, for six days and were sacrificed on the 7th day. One hundred mg of heart, brain, and kidney tissues were homogenized in 1 ml of phosphate-buffered saline. MDA, carbonyl, GSH, and catalase were analyzed by spectrophotometry. Data were analyzed using One-way ANOVA and post hoc test. Results: In heart, MDA was significantly greater in the control than in the IF and PF groups. In brain, GSH was greater in the IF than in the PF and control groups. Also, in brain, catalase specific activity was significantly greater in the control than in the IF and PF groups. In kidney, catalase specific activity was significantly less in the PF than in the control group. Conclusions: The effect of fasting on oxidative stress in various organs showed various responses, however fasting reduced oxidative stress based on MDA and GSH levels in the heart and brain, respectively.
