The aim of the present study was to investigate the effect of variable doses of single and multiwalled carbon nanotubes (SWCNTs and MWCNTs) instilled intratracheally on texture of liver and hepatic enzymes ,alanine amino transferase (ALT) and aspartate amino transferase (AST) in New Zealand white rabbits. In this study was used 70 males New Zealand white rabbits, their ages range between (12-18 months) divided into seven groups, ten for each group which instilled with Nanoparticles, At days 7 and 90 post exposure, The blood and tissue samples were collected for each group.
Instillation of SWCNTs ( 1 or 5 mg/ml/kg (b.w) or MWCNTs (1,3or 5 mg/ml/kg b.w) in the trachea of rabbits induced a significant increase in activity of ALT and AST.
Translocation of carbon nanotubes was seen from the lungs to the liver. It was concluded that: SWCNTs and MWCNTs induced hepatic injuries through its effect in activity of hepatic enzyme and the nanotubes translocated from the lung to the liver and pleura.
