Fig. 1 Liver and heart hydrogen peroxide levels (H2O2). Results are expressed as the mean ± standard error of the mean. Liver: #YC-YM p = 0.038, *YC-AC p = 0.005, ##AC-AM p = 0.005. Heart: +YC-YM p = 0.033, ‡AC-AM p = 0.006. AC = aged control; AM = aged melatonin; YC = young control; YM = young melatonin.
