Table 4. Frequency of micronuclei after treatment with andiroba oil.

		Andiroba oil (mg/kg/day)
Parameter	Negative control	500	1000	2000
MN-PCE (number)	1.66 ± 2.42	2 ± 2.09	1.16 ± 1.60	2.5 ± 1.22
MN-PCE (%)	8.33 ± 12.11	10.00 ± 10.49	5.83 ± 8.01	12.50 ± 6.12
PCE/NCE ratio	1.77 ± 0.57	2.39 ± 0.60	2.10 ± 0.63	2.29 ± 0.42

MN – micronuclei, NCE – normochromatic erythrocytes, PCE – polychromatic erythrocytes. The values represent the mean ± SD and were analyzed by ANOVA. There were no significant differences between the responses to andiroba oil and the negative control, or among the doses of oil tested.
