The animals were distributed randomically in 2 groups: GS - animals which received daily 0,1 ml/ 100 g of sacaca herbal extract through gavage, and GA -animals which received daily 0,1 ml/100g of distilled water through gavage. These were distributed in 3 subgroups with 10 animals, according to theirs euthanasia dates, which were 14th, 28th and 56th day of treatment.
RESULTS
Architectural alterations were not observed, however when it was analyzed the presence or absence of necrosis, it was observed in 50% of GS28 subgroup and 90% of subgroup. In 50% of the animals from GS28 subgroup and 90% of GS56 subgroup was observed vast degeneration areas and zonal necrosis, regarding center-lobular veins alterations, there were no alterations in any of the groups
