Abstract
Background The study investigated the modulatory roles of the aqueous leaf extract of Telferia occidentalis, a traditional haematinic, and vitamin C on cardiovascular dysfunction associated with subchronic Phenylhydrazine exposure.
Methods Fifty adult male rats were randomly selected and divided into one of five groups of ten animals each: Control; 40 mgkg−1 Phenylhydrazine (PHZ); PHZ with 100 mgkg−1 T.occidentalis; PHZ with 200 mgkg−1 T.occidentalis; and PHZ with 100 mgkg−1 vitamin C.
Results Oral exposure of rats to PHZ, without T. occidentalis or vitamin C treatment, resulted in a significant (p<0.05) decrease in the haematological parameters, but increased the blood pressure parameters of rats However, treatment with vitamin C and T. occidentalis leaf extract significantly (p<0.05) ameliorated the aforementioned PHZ-induced alterations of rats haemogram, and blood pressure. Biochemical analysis revealed significant (p<0.05) reduction in the activities of superoxide dismutase and catalase of untreated PHZ-exposed rats, but the levels of malondialdehyde, hydrogen peroxide and myeloperoxidase of the rats were significantly (p<0.05) increased compared with those of the extract treated rats. Immunohistochemical analysis revealed a greater expression of Bax-protein in the cardiac and renal tissues of the untreated PHZ exposed rats, compared with the extract and vitamin C treated groups.
Conclusions The mitigation of oxidative stress and inhibition of Bax-protein expression are probable mechanisms of action of T. occidentalis in the amelioration of haemolytic anaemia, and its use as adjunct medication in the management of some diseases is justifiable
