Carcinogenic and genotoxic risks of combined exposure to dust and radiation in oxidative stress environment

Abstract

Rats subjected to coal dust combined with radiation dose of 6 Gy in long-term period demonstrated cytogenetic disorders and changes in bronchial mucosa, arterial and arterioli walls in lung stroma, destructive changes in liver parenchyma with colliquation necrosis foci in liver lobules, on oxidative stress background. Findings are that combined experimental exposure to dust and radiation on oxidative stress background increases carcinogenic and genotoxic risks in animals.
