Role of Carnosine and Melatonin in Ameliorating Cardiotoxicity of Titanium Dioxide Nanoparticles in the Rats
The aim of this work was to study the possible cardiotoxicity of two different doses of 50 nm nano titanium dioxide (n-TiO2) and the possible modulating effects of the use of two natural antioxidants carnosine and melatonin. The results showed that TiO2- NPs produced deleterious effects on rat cardiac tissue as confirmed by the increased levels of serum myoglobin, troponin-T and CK-MB. Increased levels of serum Inflammatory markers represented by the tumor necrosis factor alpha (TNF-α) and Interleukin-6 (IL-6) was also noticed. Caspase3 and IGg were elevated compared to the control group in a dose dependant manner. treatment of the rats with Carnosine or melatonin. along with TiO2- NPs administration significantly improved most of the elevated biochemical markers. It was concluded that the use of Carnosine or melatonin could play a beneficial role against deleterious effects of TiO2- NPs
