Resumo
Many wild plants of the Cerrado bioma are used as medicinal plants.
The pequi (Caryocar brasiliensis) is representative of those equipped
with molluscicidal action against schistosomiasis. This paper sets out
to verify the toxic action of pequi fractions in other aquatic animals
before they are used in rivers or lakes. Analysis were made of the
alterations to the mitotic index of epithelia cells in the gills of guppy
(Poecilia vivipara) exposed to ethyl-acetate fraction of leaf pequi and
bark. Animals exposed to ethyl-acetate fraction (leaf), no significant
change was observed in the mitotic index when compared with the
control group, whereas in fish exposed to ethyl-acetate fraction (bark)
we detected an increase in mitotic index of the epithelia cells in two
regions of the branchial filaments. Thus, ethyl-acetate fractions (leaf)
could be used against schistosomiasis, given their high efficacy and
low action as piscicide.
