Biochemical determinants of clearance of tissue-type plasminogen activator from the circulation.

Biochemical modification of tissue-type plasminogen activator (t-PA) designed to alter pharmacokinetics and pharmacodynamics offers promise for development of pharmaceuticals particularly suitable for treatment of specific disorders and for induction of coronary thrombolysis by intramuscular as well as intravenous administration. Accordingly, to identify biochemical determinants of clearance of...

Human tissue-type plasminogen activator.

Tissue-type plasminogen activator (t-PA ) plays an important role in the removal of intravascular fibrin deposits and has several physiological roles and pathological activities in the brain. Its production by many other cell types suggests that t-PA has additional functions outside the vascular and central nervous system. Activity of t-PA is regulated at the level of its gene transcription, it...

Clearance of the heavy and light polypeptide chains of human tissue-type plasminogen activator in rats.

In order to assess which part of the tissue-type plasminogen activator (t-PA) molecule should be (genetically) modified to obtain more-slowly-clearing mutants, two-chain t-PA and its isolated heavy and light chains were radiolabelled and injected into rats. The vast majority of t-PA and the heavy chain disappeared from the blood circulation with half-lives of 2.3 and 1.0 min respectively. The c...

The Outcome of Treatment With Recombinant Tissue Plasminogen Activator in Acute Ischemic Stroke

Background: Thrombolytic therapy is the recommended treatment of acute ischemic stroke. It is crucial to evaluate the treatment results with recombinant Tissue Plasminogen Activator (r-TPA) in patients with acute stroke. Objectives: This study aimed to evaluate treatment outcomes with r-TPA in patients with acute stroke in a referral stroke center in Iran. Materials & Methods: In this retrosp...
