Effect of silibinin and vitamin E on restoration of cellular immune response after partial hepatectomy.

Our aim was to study the antioxidant and immunomodulatory effect of silibinin and vitamin E on the early postoperative course in rats that had undergone a partial hepatectomy (PHX). Male Wistar rats that were treated with silibinin (50 mg/b.w.

Lipid and DNA oxidative damage in experimentally induced hepatic porphyria in C57BL/10ScSn mice.

Patients with porphyria cutanea tarda (PCT) develop hepatocellular carcinoma as a late consequence. Pre-loading of C57BL/10ScSn mice with iron greatly sensitizes them to the induction of hepatic porphyria caused by hexachlorobenzene (HCB). HCB will also cause liver tumors in experimental animals.

Vitamin E protects against iron-hexachlorobenzene induced porphyria and formation of 8-hydroxydeoxyguanosine in the liver of C57BL/10ScSn mice.

The effect of vitamin E treatment on total porphyrin content, lipid peroxidation (LOOH) and 8-hydroxydeoxyguanosine (8-OHdG) was studied in the livers of C57BL/10ScSn mice following hexachlorobenzene (HCB) and iron treatment. HCB was administered i.p.

Effect of vitamin E on the immunoreactivity of spleen cells in hyperlipidaemic rats.

Atherogenic (lipid-rich) diet suppressed mitogen-induced lymphocyte blastogenic responses in rats. Supplementation with vitamin E completely abolished the suppressive effect of the diet. The atherogenic diet also decreased the tumour necrosis factor alpha (TNF-alpha) activity produced by spleen macrophages, however, vitamin E supplementation failed to abolish this effect.
