Aroeira’s ethanolic extract group. A – At 7 days, the granulation tissue is thick and presents macrophages, lymphocytes and rare neutrophils. Blood vessels are distributed all over the tissue and the fibroblasts are near disorganized collagen fibers at the periphery of the tissue. B - At 28 days, the connective tissue is thin with rare inflammatory cells. Blood vessels are distributed along the granulation tissue. Arrows point a hemorragic area pigmented by hemossiderin. Fibroblasts are near collagen fibers at the central and periphery regions of granulation tissue. HE – Original Magnification 40x
