AFB1/Alb in flour and sawmill workers with GSTT1 and GSTM1&GSTT1 null genotypes were significantly higher than controls, and in sawmill workers with GSTM1&GSTT1 null than flour workers. Liver enzymes (ALT and AST) in sawmill workers were significantly higher than flour workers and controls in all GST polymorphism; except in GSTT1 polymorphism, where these enzymes were significantly higher in the two exposed groups than controls.</p><strong>CONCLUSIONS: </strong>In conclusion, organic dust exposure may cause elevation in AFB1/Alb and liver enzymes of exposed workers, and GST gene polymorphism plays an important role in susceptibility to hepatic parenchymal cell injury; except in workers with GSTT1&GSTM1 null genotype, gene susceptibility seemed to have little role and the main role was for environmental exposures.}, number={2}, journal={Open Access Macedonian Journal of Medical Sciences}, author={Saad-Hussein, Amal and Shahy, Eman M. and Shaheen, Weam and Taha, Mona M. and Mahdy-Abdallah, Heba and Ibrahim, Khadiga S. and Hafez, Salwa F. and Fadl, Nevein N. and El-Shamy, Karima A.}, year={2016}, month={Apr.}, pages={312–318} }
