Objective To explore the correlation between the leukocyte rheology, cell adhesion molecule(CAM) expression and psoriasis. Methods Enzyme linked immunosorbent assay(ELISA), erythrocyte deformability apparatus and in vitro thrombus and platelet adhesion dual purpose apparatus were used to determine the changes of leukocyte CD18 expression, levels of serum soluble intercelular adhesion molecule 1(sICAM 1), and the changes of leukocyte filtration index(LFI) and leukocyte adhesion rate(LAR). Results The leukocyte CD18 expression, sICAM 1 level, LFI and LAR were significantly increased in patients with psoriasis than those in controls(P

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.
