title: [Changes in the structure of the plasmalemma of hepatocytes and its specialized portions--intercellular junctions in man in complicated forms of cholelithiasis].
abstract: As demonstrates the electron microscopic investigation of the human liver at complicated forms of cholelithiasis, there is a stage-by-stage destruction of intercellular junctions and a change in the plasmolemma structure of hepatocytes depending on the degree of the disease. The greatest disorder in the plasmolemma structure is observed at gangrenous calculous cholecystitis, as well as at mechanical jaundice and suppurative cholangitis, dependent on choledocholithiasis. The most sensitive are the gap junctions; desmosomes and intermediate junctions are the second to suffer. The structure of the tight junctions is the last to be disturbed. This results in loss of specificity by different areas of plasmolemma in the hepatocytes, and the hepatocytes themselves loose their polarity. These alterations are evidently irriversible and result in death of the cells.
