Abstract/OtherAbstract:
Hepatocytes isolated from 20- and 4-month Wistar rats and cultured with or without alpha-linolenic acid (LNA) were then added with nutraceutical YHK or sylibin before the test with iron or copper. Overall, YHK proved to be more effective than sylibin in Fe/Cu-induced peroxidative damage on normal and LNA-loaded hepatocytes (p < 0.05). YHK exerted a significant protection against DPPH radical-scavenging activity in the "old" group (p versus sylibin) and against lipophilic generators in both age groups (p < 0.05 versus sylibin). Both compounds were ineffective on age-related increase of surface-charge density. These preliminary data suggest that age per se enhances the vulnerability of hepatocytes to xenobiotics, whereas some safe nutraceuticals seem to exert significant protective effects.
