[Biochemical and morphological aspects of the aggregation capability of thrombocytes in peritonitis].

44 patients with peritonitis of different etiology and two groups of differently-aged donors (19 persons) have been examined. Blood plasma levels of malonic dialdehyde and platelet morphological properties have been studied. In patients with peritonitis platelets are deformed and solid platelet aggregates are observed. Platelet activation is accompanied by augmented malonic dialdehyde blood content, its level further increasing with the progress of peritonitis.
