The establishment of a satellite group is essential in order to
observe reversibility, persistence, or delayed occurrence of toxic
effects related to the substance tested (OECD, 2008b). The physiological habits of the animals observed during the satellite period are
shown inTable 3. There was no statistical difference in any physiological parameter between the treated animals when compared to
the control. The absence of any toxicity sign in the satellite group at
the end of the 19-day observation period indicates that the oil did
not show any delayed toxic effect in animals tested.
Table 4shows the absolute and relative weights of the vital and
reproductive organs of animals treated in the subchronic test.
Alteration of organs relative weight is also considered an evidence
of toxicity (Cunha et al., 2009). There was no statistical difference in
organs relative weight from the animals tested in relation to the
