Abstract：
:An in vitro test system was developed to examine the effects of red blood cells (RBC) on shear-induced platelet adhesion (SIPAD) and platelet aggregation (SIPAG). Suspensions of human platelets labeled with Mepacrine and suspended in citrated plasma were exposed to single, continuous or repetitive (120-300x) one second shear stress pulses of varying amplitude (15-100 dyn/cm2) in a cone-plate viscometer in the presence or absence of fresh, untreated (intact) RBC or glutaraldehyde (GLA)-fixed, rigid, adenosine diphosphate (ADP)-depleted (GLA)-RBC. SIPAG was expressed as percent loss of single platelets. SIPAD was assessed by measuring the amount of Mepacrine-related fluorescent material remaining on glass disks in the plate of the viscometer after washing with EDTA-saline to remove platelet aggregates. Intact RBC were twice as effective as GLA-RBC in potentiating SIPAG at all shear stress levels. Potentiation of SIPAD by intact RBC was markedly less than that observed with GLA-RBC at stresses below 50 dyn/cm2. These findings are consistent with the concept that while both physical and chemical (ADP) mechanisms are substantially involved in potentiation by RBC of SIPAG, RBC support SIPAD largely by enhancement of platelet transport from the bulk flow to the bounding surfaces. The findings also indicate that it is feasible to assess SIPAD and SIPAG in the same flow system simultaneously. A less complicated version of the method described here should prove useful in the evaluation of patients with platelet functional disorders, and in the evaluation and monitoring of antiplatelet agents.
