Abstract

The dose-dependent effects of propofol on expression intracellular adhesion molecule (ICAM-1) in rabbit aorta endothelial cells was examined. Twenty adult New Zeland albino rabbits were used in this study. One control and three experimantal groups were designed. In experimantal groups; for group I propofol was not applied, group II 0.5, group III 4.0 and group IV 8.0 mg/kg propofol were applied to rabbits by marginal ear vein. One hour after applying propofol, control and experimantal group rabbits were sacrificed and their aorta were removed. The sections were stained with APAAP immunohistochemical staining for evaluation using a light microscope. This marked ICAM-1 immunoreactivity was maintained in 8.0 mg/kg of propofol applied to rabbits of aorta endothelium, whereas mild stain was observed for other experimantal groups. The present study indicated that there is parallel relationship between endothelial cells ICAM-1 expression and different doses of propofol.

Key words: ICAM-1, rabbit, aorta endothelium, propofol.
