The composition of lipid phase of red-cell membrane in patients with ischemic heart disease (IHD) with pronounced postperfusion hemolysis (18 patients) before coronary artery bypass surgery and 1 hour after the completion of cardia bypass (CB) has been studied. It is shown that patients with IHD with pronounced hemolysis are characterized by the normal ratio of phospholipids (PL) fractions in red-cell membrane before surgery, which is connected with eth high content of young forms of red cells in blood at this stage. After surgery, the fraction of lysophosphatidylcholine and phosphatidic acid in red-cell membrane increases against the background of decrease of phosphatidylinositol and phosphatidylcholine, which likely reflects the simultaneous activation of phospholipases of three classes (A, C, and D) in red cells during CB. Regardless of the phase of the study, the total content of PL in red-cell membrane of IHD patients with pronounced hemolysis is decrease at the high level of cholesterol (CS) and the CS/Pl ratio.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
