Aquilegia vulgaris L. extract counteracts oxidative stress and cytotoxicity of fumonisin in rats

Exposure to fumonisins (FB) is known to have toxic and carcinogenic effects in different animal species, and to express toxicity in cells via the induction of oxidative stress. The aim of the current study was to evaluate the protective effects of the ethanol extract of Aquilegia vulgaris L. against the oxidative stress and the genotoxicity using micronucleus assay and random amplified polymorphism DNA (RAPD-PCR) in FB-treated rats. Sixty mature female Sprague–Dawley were divided into six treatment groups and treated for 4 weeks as follow: the control group, the group fed FB-contaminated diet (200 mg/kg diet), the groups treated orally with the extract (5 and 10 mg/kg bw) and the groups fed FB-contaminated diet and treated with the extract at the two doses. The results showed that treatment with FB alone disturbed lipid profile in serum, increases Sa/So ratio, induces micronucleated polychromatic erythrocytes (Mn-PCEs) in bone marrow, increases DNA and RNA in liver accompanied with significant changes in histological picture The extract alone at the two tested doses did not induce any significant changes in the biochemical or histological picture. The combined treatment showed significant improvements in all biochemical, cytogenetic parameters tested and histological pictures in the liver tissues. Moreover, this improvement was more pronounced in the group received the high dose of the extract. It could be concluded that the ethanol extract of A. vulgaris induced its protective effect via the increase in the antioxidant capacity, inhibition of lipid peroxidation and scavenging of free radicals.
