title: [Ultrastructure of the ductal epithelium in the human pancreas in chronic pancreatitis].
abstract: Three different kinds of cells are distinguished within the epithelium of the pancreas ducts in patients with chronic pancreatitis: main ductal cells among which there are "light" and "dark" forms differing from each other in the level of their biosynthetic apparatus development and being in the state of different functional activity; endocrine cells with morphological features of chromaffin-like and D-cells of the gastrointestinal tact; migrating cells (histocytes, granulocytes, lymphocytes). Characteristic features of destruction in the pathologically altered epithelium are described.
