| pubmed-article:3114346 | pubmed:abstractText | The fibrinolytic activity of saliva from healthy males was studied on plasminogen-free and plasminogen-rich fibrin plates. A cell-bound plasminogen activator in human unstimulated and stimulated whole saliva was demonstrated. The assessed fibrinolytic activities could always be quenched by incorporation into the fibrin plates of IgG antibodies raised against human two-chain tissue-plasminogen activator (t-PA), while additional experiments indicated the absence in normal human saliva of urokinase-like and factor XII-dependent plasminogen activators as well as the absence of inhibitors of fibrinolysis. Thus, t-PA is the only type of plasminogen activator in normal human saliva. The present findings seem to support our recent clinical observations of a decrease in the incidence of bleeding complications and need for replacement therapy in hemophiliacs undergoing oral surgery during local antifibrinolytic therapy with tranexamic acid. Whether the findings might also be of importance in other pathological conditions of the oral cavity, such as impaired wound healing, remains to be elucidated. | lld:pubmed |
