Effects of cysteine compounds on hepatic MDA levels following CCl₄ administration. CCl₄ (2 ml/kg, 25% in corn oil) was intraperitoneally injected into rats twice a week for 12 weeks. Rats were randomly divided into 7 groups at 4 weeks after CCl₄ injection. SAC, NAC, and CYS were administered to rats as a mixed diet of the expressed dose per day. At 1 week after the final CCl₄ treatment, the animals were sacrificed, and assays were performed as described in the Materials and Methods. Data are presented as the means ± SEM of at least 5 animals. ^††p<0.01 vs the sham group. *p<0.05, **p<0.01 vs the vehicle group.
