Resumo

Thirty adult male Wistar rats were used in five groups. Two groups received oral treatment with aqueous solution of the Tordon® in different concentrations. Treatment O1: 2mL/L, (n=6); Treatment O2: 4mL/L, (n=6). Two groups received topical treatment in the cervical area: Treatment T1: 16.67mL/L (n=6), and Treatment T2: 400mL/L (n=6). A group control was used without the addition of the herbicide (n=6). Forty days after start of the experiment, the weight of the rats was assessed and they were euthanized; the internal organs (testis, liver, kidneys, spleen and intestine) were collected and their weights were assessed. There were no differences (P>0.05) in the body and organs weights among treatments. However, the proportional weight (%) of the liver in relation to body weight was higher in the O1 and O2 treatments (P<0.05) as well as the proportional weight of the kidneys in the O2 treatment. The T1 and T2 animals did not show harmful effects.
