Fig. 2From: Novel approach to gastric mucosal defect repair using fresh amniotic membrane allograft in dogs (experimental study)Gastric endoscopic examination at the 10th and 21st postoperative day and exploration findings (after gastrostomy) at 21Â days. a Gastroscopy of the positive control group at 10th postoperative day; in which the arrow showing clotted blood covering mucosal defect and adhered food remnants. b Gastroscopy of the AM group at 10th postoperative day; the arrow revealing AM covering mucosal defect with neither inflammatory reaction nor bleeding in surrounding mucosa. c Gastroscopy of the positive control group at 21st postoperative day; the arrow showing small circular ulceration at the mucosa. d Gastroscopy of the AM group at 21st postoperative day; the arrow revealing no detectable mucosal defect or AM remnant. e Gastric exploration during surgical biopsy of the positive control group at 21st postoperative day; in which the arrow showing small circular ulceration of gastric mucosa with mild bleeding and surrounded by inflammatory zone. f Gastric exploration during surgical biopsy of the AM group at 21st postoperative day; the arrow showing no detectable mucosal defect or AM remnants on the mucosal surface and no signs of inflammation or bleedingBack to article page
