The relevance of cell size on ultrasound-induced hemolysis in mouse and human blood in vitro
2003
Abstract This paper describes a further test of the hypothesis that cell size is an important physical parameter in ultrasound (US)-induced hemolysis, that is, the larger the cell the greater the potential for sonolysis by a cavitational mechanism. Mouse (M) and human (Hu) erythrocytes in vitro were used; their mean corpuscular volumes were 49.0 and 89.5 fL, respectively. At a US exposure in vitro in the presence of Albunex® that yielded an average of 36.8% hemolysis for M blood, the Hu blood yielded an average of 54.0% hemolysis. The data supported the hypothesis. This paper also briefly discusses the difficulty of extrapolating sonolytic in vitro results to those derived in vivo . (E-mail: Morton_Miller@urmc.rochester.edu)
