Abstract
Literature data indicate l-carnitine (LC), a trans-mitochondrial carrier of acetyl and long chain groups, as an agent possessing protective effects against oxidative stress in mammalian cells. However, the major factor involved in the protective mechanism is not known. The protection activity exerted by this agent against reactive oxygen species induced by hydrogen peroxide (H2O2) and t-butylhydroperoxide (t-butyl-OOH) treatment in isolated human peripheral blood lymphocytes (PBLs) has been studied. Human lymphocytes cells were isolated and pre-incubated with 5 mM lc before H2O2 (100 µM) and t-butyl-OOH (400 µM) treatment. The protective effect of lc on treated PBLs was measured by single cell gel electrophoresis and the analysis of chromosomal aberrations. Results show that lc treated cells exhibited a significant decrease in the number of oxidative induced single-strand breaks and chromosomal aberrations.
