摘要:: The adhesion of blood cells to endothelium can be studied in vitro using human endothelial cells in culture. This experimental model and radiometric techniques provide us with a simple system to quantify the adhesion of blood cells to endothelium. Normal human granulocytes isolated by density gradient adhere to normal endothelial cells in a proportion of 25%. Human promyelocytic cells (HL 60) induced by retinoic acid into mature cells adhere as well as normal granulocytes while the noninduced adhere poorly to endothelium. A small percentage of normal red cells attach to endothelial cells while red cells from patients with sickle cell anemia or diabetes mellitus have a significantly increased adhesion to endothelial cells (P greater than 0.001). This adhesion is statistically correlated with the extent and severity of vascular complications in diabetes mellitus (P less than 0.05). The addition of fibrinogen significantly increased (P less than 0.01) the adhesion of normal red cells, red cells from patients with sickle cell anemia or diabetes mellitus while gamma-globulins did not modify adhesion. Fibronectin potentiated the adhesion of normal red cells.
