title: [Electrophoretic studies of the composition of peripheral mononuclear cells during operations with extracorporeal circulation].
abstract: The increased incidence of infections after operations can be connected with changes of the immunocompetent cells. Mononuclear blood-cells were investigated by means of the cell electrophoresis during and after operations under the extracorporeal circulation, because electrophoretically different cells correlate with several immunological phenotypes. A heavy decrease of the electrophoretic quick mobility cell population was found out on the first postoperative day above all. This change allows itself the interpretation by decreasing the T-lymphocytes connected to a relative increase of monocytes, B-cells, and immature T-cells. Besides a lower quotient of the quick and low mobility T-cells refers to a lower immunoregulatory quotient CD4/CD8 after operation. Changes of the cell composition becomes evident also in dependence on the bypass length and the blood supply.
