Description : As thrombin generation proceeds, the body has natural anticoagulant systems opposing further thrombus formation. Natural anticoagulants include: a. Tissue plasminogen activator (TPA) b. Antithrombin III c. Activated protein C d. Heparin cofactor II

Last Answer : Answer: a, b, d Streptokinase is a bacterial protein produced by group C b-hemolytic streptococci. It is therefore antigenic in humans and can be associated with allergic reaction in ... one agent over the other. Streptokinase however, is markedly less expensive than either urokinase or TPA

Last Answer : (B) Streptokinase
Description : Which of the following is/are true of the actions of transforming growth factor beta (TGF-b) during wound repair? A. Increased matrix and proteoglycan synthesis. B. Inhibition of proteases. ... of plasminogen inhibitor. D. Chemotaxis for fibroblasts and macrophages. E. Autoinduction of TGF-b.
Last Answer : Answer: ABDE DISCUSSION: Through autocrine and paracrine mechanisms TGF-b stimulates the deposition of collagen and other matrix components by fibroblasts, inhibits proteases, blocks plasminogen inhibitor, ... effects. The sustained production of TGF-b at the wound site leads to tissue fibrosis
Description : Which fibrinolytic agent(s) selectively activate(s) fibrin bound plasminogen rather than circulating plasminogen: A. Urokinase B. Streptokinase C. Alteplase D. Both ‘A’ and ‘C
Last Answer : C. Alteplase
