  • Title: Influence of plasma hemostasis on insulin action in vitro.
    Author: Kleniewski J.
    Journal: Endocrinol Exp; 1975 Sep; 9(3):223-7. PubMed ID: 1081045.
    Abstract:
    The influence of various components of plasma hemostatic system on the assimilation of glucose by isolated rat hemidiaphragm in the presence of insulin was investigated. The addition of streptokinase and human plasminogen to the incubation medium decreased the rate of glucose assimilation. This effect did not occur when trasylol, an inhibitor of plasmin, was added to the assay system. The glucose assimilation by hemidiaphragms incubated in buffer with glucose and insulin was not influenced by thrombin, fibrinopeptides, fibrin degradation products, plasminogen, streptokinase or trasylol added separately to the assay system. The mechanism of the influence of plasmin on insulin action was partly elucidated in further experiments. Thus, less 125I-insulin was bound by isolated fat cells preincubated with plasmin than by control cells.
