A-H: H & E and AB/PAS staining. (A & B) Control: Normal unoperated submandibular gland showing the typical appearance of acini and ductal cells. (C & D) 24 hr ligated: Large numbers of infiltrating inflammatory cells in the increased stroma and interstitial spaces (arrows). (E) 2 wk ligated – H & E: Luminal dilation of ducts (arrow), absence of acini, and extensive inflammation. (F) 2 wk ligated – AB/PAS: Loss of cellular secretory granules and presence of material in the lumen of ducts (arrow). (G) 3 days following removal of 2 wk ligation – H & E: Some acini (arrow head) and ductal cells (arrow) have recovered some of their size, while acinar-ductal branch structures are also visible (double arrow head). (H) 3 days following removal of 2 wk ligation – AB/PAS: Some acini have recovered their glycoprotein content (arrow head).
