title: Acidic glycosaminoglycans of abdominal mucin in a case of pseudomyxoma peritonei caused by appendiceal cancer.
abstract: Although the use of intraperitoneal mucolytic agents is useful in the management of pseudomyxoma peritonei, effective removal of mucin is difficult even by repeated mucolysis in cases with massive ascites. To establish mucolytic therapy as a further effective procedure, biochemical analysis of mucin is required in greater detail. We reported here a case of pseudomyxoma peritonei caused by primary appendiceal cancer with biochemical analysis of mucin. The abdominal cavity in this case was filled with massive mucinous ascites. Although the mucolytic therapy was performed repeatedly, it was not effective in preventing mechanical ileus which was followed by surgical exclusion. Biochemical study of mucin showed that the mucin contained a small amount of hyaluronic acid, as characterized by electrophoretic study. These data led us to the hypothesis that the hyaluronic acid component plays a role in the pathogenesis of the replacement of mucin in the abdominal cavity.
