Abstract
Background: Sodium arsenite is a dangerous bio-accumulative poison affecting a large number of people as well as animals throughout the world. It is used clinically in the treatment of certain medical conditions, but due to its harmful damage to different tissues and mainly the cardiotoxicity, its medical application is limited.Aim: This study was conducted to investigate the protective effects of spirulina on cardiotoxicity induced by sodium arsenite biochemically and histologically.Methods: 30 young adult male albino rats were randomly equally divided into three groups 10 animals each. Group I (control), Group II Arsenic intoxicated (10 mg/kg/day/ 4 weeks), Group III spirulina protected animals (concomitant sodium arsenite 10 mg/kg/day/ 4 weeks and spirulina 200 mg/kg/day/ 4 weeks).Results: It was evident from the study that arsenic exposure exerted a significant increase in cardiac enzyme levels, serum creatine kinase MB (CKMB) and troponin. Concomitant treatment with spirulina is considerably recovered their serum levels. Histological alterations associated with arsenite treated animals are significantly decreased after using spirulina.Conclusions: The results of the present study showed that use of spirulina could alleviate the toxic effects on the heart following exposure to arsenic toxicity.
