1.The measurement of thrombomodumin,thrombin-antithrombin and D-dimer in plasma from patients with disseminated intravascular coagulation and its diagnostic significance
Chinese Journal of Primary Medicine and Pharmacy 2005;0(02):-
Objective To analyse the relationship between the diagnosis of disseminated intravascular coagulation(DIC) and the level of Thrombomodumin(TM),thrombin-antithrombin(TAT) and D-dimer in plasma from 67 patients with disseminated intravascular coagulation(DIC).Methods The levels of TM,TAT and D-dimer were measured by a two antibody sandwich enzyme linked immunosorbent assay and a latex aggregation assay.Results The levels of TM,TAT and D-dimer in plasma of patients with DIC were higher than those in control group(P

Objective To observe the effects of elevated temperatures(37~44.5℃)on the cell counts, hemolysis and osmotic fragility of stored red blood cells.Methods After 7~35 days of storage at 4℃, erythrocyte suspensions were heated by incubation at 37℃ and 44.5℃ for 30 min in an incubator and then examined for cell counts, hemolysis and osmotic fragility.Results Red blood cell, white blood cell and platelet counts, hemoglobin and potassium were unchanged following the heat treatment. In the osmotic fragility test, hemolysis remained within normal limits. Hemolysis of groups incubated at 37℃ and 44.5℃ began at (4.41?0.38)g/L and (4.3?0.2)g/L respectively while a complete hemolysis occurred at (3.42?0.36)g/L and (3.4?0.1)g/L , showing no significant difference compared to the room temperature control (4.5?0.18)g/L and (3.6?0.1)g/L. There was no significant distinction in the proportions of smooth spherocyte among the samples incubated at different temperatures, except the samples stored for 35 days, probably due to the long storage period.Conclusions Heating at temperatures between 37~44.5℃ for as long as 30 min does not cause hemolysis or other damage to red blood cells.
