Effects of Mercury Chloride And Lead Nitrate Induced Cardiotoxicity in Male Rats
Abstract
Background: Lead nitrate and mercury chloride are widespread environmental and industrial pollutant,
which induces severe alterations in the body tissues of both humans and animals. In the present study, the
effects of lead and mercury induced cardiotoxicity was studied in Wistar rats.
Methods: Lead nitrate (LN, 45 mg/kg bw/day) and mercury chloride (MC, 0.02 mg/kg bw/day) and their
combination were administered orally for four weeks. Four groups of rats were used in the study: control, LN,
MC and LN plus MC groups. Malondialdehyde (MDA) level, antioxidant enzyme activities [superoxide
dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione-S-transferase (GST)] and
histopathological changes in heart tissue were evaluated.
Results: Results showed that LN and MC exposure and also their combination resulted in an increase in the
SOD, CAT, GPx, GST activities and also MDA levels, with respect to the control group. Light microscopic
investigations revealed that mercury chloride and lead nitrate and also co-treatment of them induced
histopathological changes in heart tissue.
Conclusion: As a result, combination of LN plus MC was more harmful than use them alone.
