| Abstract: | Abstract: We previously reported that Lixelle, which was used for beta2‐microglobulin (BMG) adsorption columns, could adsorb not only BMG but also inflammatory cytokines. We became interested in the application of Lixelle for patients with endotoxinemia and researched its ability to adsorb microorganism components in vitro using lipopolysaccharide (LPS) (Escherichia coli B8), endotoxin (ET) contaiminated water. The initial concentrations of each water solution were LPS (ET 29,135 EU/L) and contaminated water (ET 3,523 EU/L) whole blood solution was LPS (ET 1,197.6 EU/L). Each 2.5 ml of the stock solution and adjusted diluted solutions contained 0.5 ml of Lixelle beads. After shaking at 37°C for 2 h, ET in the solutions was determined using the endotoxin specific‐limulus amebocyte lysate method. The results revealed that even though ET concentrations in LPS and contaminated water incubated in water solution and in whole blood were high, the samples containing Lixelle beads showed significant decreases. Thus, Lixelle beads can adsorb not only BMG but also microorganism components such as LPS and ET. These findings together with the ability of Lixelle to adsorb ET show the possibility of the application for treatment of endotoxinemia. |
