Effect of anionic amphophiles on erythrocyte properties
Annals of the New York Academy of Sciences
|January 1, 1983
Summary
Anionic amphophiles like 2,5-dihydroxybenzene sulfonate and acetylsalicylate reduce red blood cell aggregation by increasing negative charge. This may benefit vascular diseases by diminishing erythrocyte aggregation.
Area of Science:
- Biochemistry
- Hematology
- Pharmacology
Background:
- Increased erythrocyte aggregation is implicated in various disorders.
- The precise role of erythrocyte aggregation in disease pathogenesis is not fully understood.
- Anionic amphophiles may mitigate vascular disease by altering red blood cell surface charge.
Purpose of the Study:
- To investigate the effects of 2,5-dihydroxybenzene sulfonate and acetylsalicylate on erythrocyte behavior.
- To explore the mechanism by which anionic amphophiles influence erythrocyte aggregation.
- To assess the potential of these agents in managing conditions associated with erythrocyte aggregation.
Main Methods:
- Erythrocytes were suspended in phosphate-buffered saline with dextran.
- Viscosity and erythrocyte sedimentation rate were measured.
- Hemolysis protection and aggregation inhibition (using MAI technique) were assessed after sialic acid removal.
Main Results:
- 2,5-dihydroxybenzene sulfonate showed a marginal reduction in low shear rate viscosity.
- Both agents protected erythrocytes from hemolysis.
- Aggregation of sialic-free erythrocytes was unequivocally interfered with by both agents.
Conclusions:
- Anionic amphophiles can reduce erythrocyte aggregation, potentially via interaction with surface charge.
- The observed effects on viscosity, though modest, suggest a real impact on erythrocyte behavior.
- These findings support further investigation into anionic amphophiles for vascular disease treatment.
