THE STUDY ON THE MECHANISM OF PROTECTING ERY- THROCYTE DEFORMABILITY OF PSS AND PGMS IN PATIENTS WITH ACUTE MYOCARDIAL INFARCTION / 中国海洋药物

ABSTRACT

To explore the mechanism of protecting erythrocyte deformability (ED) of polysaccharide sulfate(PSS)and propyllene glycolmannurate sulfate(PGMS) in patients with acute myocardial infarction (AMI). The erythrocyte filtration index(EFI),erythrocgte membrane Na+,K+-ATPase .glutathione peroxidase(GSH-Px)activity and lipid peroxide(LPO) were measured in 52 patients with AMI. Meanwhile the effects of PSS and PGMS on EFI, Na+,K+-ATPase ,GSH-Px and LPO in AMI patients were observed in vitro. The results showed that the EFI and LPO were markedly higher ,Na+ ,K+-ATP ase and GSH-Px were si-hnificantly lower in patients than those in control(P0. 05). These results indicate that PSS and PGMS could improve the ED in patients ,and the efficacy of PSS or PGMS was related to enchancement of erythrocyte membrane ATP-ase anci GSH-Px activity.
