title: [Fibrinolytic activity of human peripheral blood granulocytes].
abstract: The fibrinolytic activity of human peripheral blood leukocytes was studied by plating the cells on 125I-fibrin coated dishes. The separation of the three major leukocyte types allowed to demonstrate that most of the activity was produced by granulocytes. The rate of fibrinolysin was found to be linear with incubation time and cell number in the range of 1-4 X 10(5) cells/ml. Since little activity was found in absence of exogenous plasminogen, it was concluded that the cell fibrinolytic activity depended mostly upon the release of plasminogen activator. Plasmatic and granulocytic activators obtained from the same amount of blood were found to be of similar level suggesting a possible clinical implication of the cellular activity in the thrombolytic system.
