Abstract
Cultured confluent human umbilical vein endothelial cells were irradiated in vitro by {sup 60}Co-gamma ray at doses from 0 to 50 Gy. After irradiation Thrombomodulin in the supernatants of endothelial cell culture medium, on the surface of the cells and within the cells was measured at different times over six days. At twenty-four hours after irradiation, an increase in the release of Thrombomodulin and von Willebrand factor from irradiated endothelial cells and an increase in the number of molecules and the activity of Thrombomodulin on the surface of the cells were observed, which were radiation-dose dependent. The capacity of the cells to produce and release Thrombomodulin was decreased from two to six days after exposure to {sup 60}Co-gamma ray. Our data indicate that radiation can injure endothelial cells and that Thrombomodulin may be as a marker of radiation-induced endothelial cell injury. The relationship between dysfunction of irradiated endothelial cells and the pathological mechanisms of acute radiation sickness are discussed.
