Mercury in pancreatic acinar cells. The areas in the dashed rectangles are shown at higher magnifications in the insets. (A) Some acinar cells (e.g., in the inset) contain black mercury grains. A nearby large islet (arrow) has mercury-positive peripheral and internal cells. A small duct (arrowhead) adjacent to the islet does not contain mercury. (B) A group of glands (within the dashed rectangle) have acinar cells containing cytoplasmic mercury (inset). A nearby islet (ISL, within the dashed line in the right lower corner) has peripheral cells (e.g., arrowhead) that contain mercury. Autometallography/hematoxylin.
