Activation of the contact and complement systems in C1-inhibitor deficiencies is thought to contribute to the pathogenesis of angioedema attacks by releasing kinins. Trigger stimuli of attacks may also activate coagulation. This is particularly important because experimental data suggest that thrombin, the main enzyme of the coagulation cascade, increases(More)
Recombinant tissue-type plasminogen activator (rt PA) is currently used as a thrombolytic agent in the management of acute myocardial infarction (AMI). Since it is known that other recombinant proteins induce antibody formation when administered to humans, we determined the presence of anti-rt-PA antibodies in serial blood samples from 60 AMI patients (43(More)
The vasoactive peptide bradykinin may be involved in the pathogenesis of vasodilation, which has been considered the initiating event of ascites formation in cirrhotic patents. Since bradykinin is generated through the cleavage of high molecular weight kininogen (HK) by kallikrein, we looked for the cleavage of HK by an immunoblotting technique in plasma(More)
