    Notes: Abstract Objectives: The interactions between blood and vascular wall cells are essential for the understanding of pathophysiologic processes, e. g. inflammation. The influence of the anesthetic drug thiopental on leukocyte function is well documented. Recently, an inhibitory effect of thiopental on leukocyte chemotaxis in a Boyden chamber assay (i. e. endothelial cells were not included) was demonstrated. In vivo, leukocytes have to interact with endothelial cell monolayers to invade the tissue. The influence of thiopental on a monolayer of endothelial cells has not yet been investigated. The aim of the current study was to investigate the influence of thiopental on the migration of leukocytes through endothelial cell monolayers (ECM). Material and methods: Human umbilical vein endothelial cells (HUVEC) were isolated and cultured on microporous membrane filters to achieve a monolayer. Isolated polymorphonuclear leukocytes (PMNL) as well as ECM were preincubated with different concentrations of thiopental. The rate of leukocyte migration against the chemotactic protein formyl-methyl-leucyl-phenylalanine was measured (n = 7). Thiopental was able to reduce the amount of leukocyte migration through ECM significantly. Conclusion: In conclusion, we could show that thiopental is able to reduce the migration of PMNL through ECM significantly.
