However, it may have exerted its protective effect against APAP hepatotoxicity by either inhibiting the bio-activation of APAP or the inactivation of NAPQI reactive intermediate as it prevented drop of GSH levels. Inducing repair process in the liver cells may also be involved in the mechanism of hepatoprotection of tomato extract. Lipid peroxidation was also decreased by the extract which suggests prevention of free radical formation in the process of APAP toxicity.

ADN is a very potent antiarrhythmic drug, with almost ideal antiarrhythmic properties; however, its use is limited by the not infrequent and sometimes serious side effects. The mechanism of ADN toxicity is multifactorial and still uncertain. Adverse effects of ADN on the cell immune responses have been reported to be mediated by phospholipase inhibition or drug-induced oxidative stress and membrane destabilization (Massey et al., 1995). The pathogenesis of ADN-induced pulmonary toxicity is not well known. Our results showed a decrease in reduced GSH levels and a slight increase in lipid peroxidation after administration of ADN which suggests that an oxidative stress mechanism is involved in its pulmonary toxicity. Other researchers also have proposed an oxidant mechanism and showed that several antioxidants can reduce lysosomal phospholipidosis and prevent ADN toxicity (Ruch et al., 1991; Agoston et al., 2003). In this research, tomato extract rich in lycopene prevented GSH depletion and induction of lipid peroxidation and partially prevented tissue damage by ADN, which suggests an oxidative stress and free radical involvement, although it may not be the main mechanism of pulmonary toxicity of ADN. Cyclosporin A, a cyclic decapeptide of fungal origin, is the most widely used immunosuppressive drug in organ transplantation and in the treatment of autoimmune disorders. However, its clinical use has been hampered by frequent reports of its nephrotoxicity.
