title: The effect of malonyldialdehyde on viscosity of normal and sickle red blood cells.
abstract: This study has examined the effect of MDA, an end product of lipid peroxidation, on the viscosity of AA and SS RBC suspensions. MDA accumulation in RBC was accomplished in vitro in human RBC by treating them with exogenous standard MDA. MDA accumulation assessed by the thiobarbituric acid reactivity of in vitro MDA-treated RBC was comparable to that of the RBC in vivo in hemolytic anemias. There was a significant increase in the viscosity of both AA and SS RBC suspensions after in vitro treatment with MDA. The increase in viscosity or RBC was significantly positively correlated with the extent of MDA accumulation.
