Ultrastructural view of colon anastomosis under propolis effect by transmission electron microscopy

Figure 4 An overview of healing at day 14 after operation. The micrographs “A-F” represent hematoxylin-eosin stained sections, “G” mallory-azan stained section, and “C, D, H” T.E.M. images of the control (upper panels) and propolis (bottom panels) group. Arrow: The anastomosis site; Arrowhead: Collagen; s: Suture material; SM: Submucosa; SE with arrow: Squamous epithelium; CE with arrow: Cuboidal epithelium; M: Macrophage; AC: Apoptotic cell; NC: Necrotic cell; GT: Granulation tissue; Eo: Eosinophil; E: Epithelium; GCE: Glandular columnar epithelium; F: Fibroblast.
