Frequency of MN and CA in bone marrow cells simultaneously exposed to PM and OLE

Treatments	Values
	Number of MNPCE per animal	Number of CAs per animal
Group A (control)	0.46 ± 0.22a	1.82 ± 0.46a
Group B (OLE; 500 mg kg−1)	0.48 ± 0.25a	1.76 ± 0.55a
Group C (PM; 60 mg kg−1)	3.85 ± 1.14c	4.47 ± 0.87c
Group D (OLE plus PM)	1.54 ± 0.73b	2.66 ± 0.81b

(Values are means ± SD of five experiments. Means shown by the same letter are not significantly different from each other at a level of 5%, using Duncan’s test. For example, the means shown by the letter b is different from a or c. In other words, the means having the different letters are different from each other)

MNPCE micronucleated polychromatic erythrocytes, CA chromosomal aberrations, chromatid/chromosome gaps chromatid/chromosome breaks and centric fusions or fragments were considered as same in CA assay
