The decision not to include such therapy may be due to the concerns about bleeding, and in patients with CLD, due to the condition called "already anticoagulated due to liver failure" This persuasion has been cleared away with a definition of "rebalanced hemostasis" in patients with CLD, since all levels of the hemostatic process may be impaired, including primary hemostasis with thrombocytopenia and platelet dysfunction, coagulation with an impaired coagulation factor production, and increased fibrinolysis due to increased levels of tissue plasminogen activator, decreased levels of alpha 2 antiplasmin, factor XIII, and thrombin-activatable fibrinolysis inhibitor, and increased levels of fibrin degradation products that may influence normal hemostatic process (9-11).

The following exclusion criteria were applied: anemia (hemoglobin [less than or equal to] 11 g/dL), fever or other symptoms suggesting active infection, severe dehydration, sensitivity to bovine blood products, concomitant treatment with antiplasmin agents or aprotinin, and unsuitability for enrollment based on the opinion of their managing physician.
Scorpion venom active polypeptide with its anti-inflammatory, antiplasmin, antibacterial, and other pharmacological effects gradually attracted the researchers' attention.

(24) A study on black-headed vultures (Coragyps atratus) indicated that coagulation and fibrinolysis is activated simultaneously in that species, as in other vertebrates, (9) whereas an early study of Japanese quail (Coturnix japonica) reported that spontaneous but delayed fibrinolysis takes place (25) and suggested that the activity of avian antiplasmin is equal to that of human antiplasmin.
The plasma proteins such as plasminogen and fibrin that were entrapped in the clots might have contributed to their sensitivityto lysis; in addition, the plasma milieu contains soluble proteins such as plasminogen, tissue plasminogen activators, and [[alpha].sub.2] antiplasmin all of which also play crucial role in clot lysis [9].
Plasminogen, AT3, protein C and S, alpha-2 antiplasmin and alpha-1 antitrypsin are also produced in the liver.
Possible explanations for bleeding with normal coagulation profile in the remaining 1401 (76.3%) patients include local causes, heterozygosity of inherited coagulation factor deficiency, vWD, some forms of dysfibrinogenemias, platelet function defects like release reaction abnormalities, hereditary haemorrhagic telangiectasia, allergic and other vascular purpuras, a2 antiplasmin deficiency, elevated levels of plasminogen activator, testing at inappropriate post transfusion time, high levels of one factor masking deficiency of the other and result fluctuation from time to time.
MMP-12 has a broad range of substrates, including α-1 proteinase inhibitor, α-2 antiplasmin, plasminogen activator inhibitor-2, collagen IV, laminin, fibronectin, elastin, but not interstitial collagens.8-9
Furthermore, platelets (which are a rich source of FXIII antiplasmin) appear to supplement this inhibitory function.
