Resumo

The present work aimed to characterize the effects of the raw extracts of the plants Eugenia uniflora (Pitanga), Solanum paniculatum (Jurubeba) and Hyptidendron canun, in concentrations of 20, 60 and 100ug/L, in the branquial epithelium of guppy (Poecilia vivipara).The data on the area and perimeter of the branquial filament, frequency, area and perimeter of mithocondria-rich cells of the basal, intermediate and apexis regions of the covering epithelium of the branquial filaments were evaluated. The statistical analysis of these data indicated that the raw ethanolic extracts of S. paniculatum and H. canun, in the tested concentrations, cause damages to the branquial epithelium and to the guppy mithocondria-rich cells. In the other hand, the aqueous raw extract of E.uniflora demonstrated a high cytotoxicity for the guppy’s cells, in general, considering that 100% of the specimens died in the first three hours of exposure.
