Introduction<\/strong><\/p>\n

Hemostasis means regulating the blood loss consequent to bleeding. It should not confuse with similar word homeostasis which means maintenance of the body’s internal environment within physiological limits. In the blood vessels, the blood normally circulates in a fluid state. But if it is drawn from the body, it thickens and forms a gel called a clot. The process is called clotting or coagulation. Natural human circulatory or blood vessel systems are presented with two contending qualification to confirm the feasibility of the entity or organism: tissue intromission must be conserve at any movement, and the bleeding must be rapidly ceased at sites of blood vessel injury1<\/sup>. Cardiovascular illness caused by formation of thrombus is one of the most dangerous conditions which is rapidly increasing at an alarming rate in current times2<\/sup>. Hemostasis and fibrinolysis represent the important dynamics for stopaging the free flow of blood at sites of damage or injury and reinstate blood vessel capacity or potency during process of recovery of wound or healing correspondingly. The term hemostasis or coagulation refers to the transformation of dispersible fibrinogen into insoluble fibrin. This technique occurs by step by step process of enhancing the enzymatic activation in which the formation of an inactive state of plasma proteins into an active protease (serine) product3<\/sup>. Thrombin serves as the central serine protease of the coagulation cascade4<\/sup>. Blood clot formation is a censorious step in the vascular related diseases which includes myocardial infarction, hypoxia (anoxia), hypertension5<\/sup>, sudden heart blockage and infarction disorders that stand for a considerable number of mortality in Worldwide6<\/sup>.Intense research activity in the antithrombotic field was devoted to compounds showing antiaggregatory potency during the last three decades of the 20th<\/sup> century. Among the huge number of synthetic molecules tested, only very few of them found in clinical use (Dupinet al<\/em>., 2002). Intravenous tissue plasminogen activator infusion is the fastest way to initiate thrombolytic therapy; however, poor recovery can be expected in up to 50% of patients (Alexandrov et al<\/em>., 2001). Tissue plasminogen activator delivery to the thrombus is dependent on the residual flow to and around the arterial obstruction when given intravenously (Alexandrov, 2004). Though, thrombolytics which includes aspirin, warfarin, antiplatelet (Clopidogrel) and heparin have shown efficacy and are widely dispensed medications in many cardiovascular and cerebrovascular diseases, the main adverse effects of use of these medications were an increased incidence of over bleeding(Bond et al<\/em>., 2005). The recent epidemiological status from WHO has given the statement that ischemic related heart disease and sudden heart blockage alone caused 9.8 million deaths Worldwide. Cerebrovascular stroke is the stoppage of blood to some areas of the brain leads to brain dysfunction.<\/p>\n

Clotting (coagulation) occurs through a process of a series of reactions and thrombin is the last enzyme that plays a vital role in the coagulation cascade which converts fibrinogen into insoluble fibrin (Fig 1)7<\/sup>. There are thirteen factors are involving in the coagulation and thrombin activates factor-XIII, enhance the formation of factor-V, which increases the thrombin formation and stimulates thrombocytes (platelets), and cause platelets aggregation8<\/sup>. Platelets respond to injury of blood vessels by first adhering to the vascular endothelial matrix as a single layer of cells. Throughout of lifetime in blood circulation, were exposed to a variety of external stimuli that control and regulate their state of activation9<\/sup>. The adhesion of platelets to the matrix is mediated by von Willebrand factor, a plasma glycoprotein that links platelets through their specific proteins (called surface glycoprotein) IX\/lb receptors to collagen, by direct association with collagen through their surface glycoprotein Ia\/IIa receptors. The primary extracellular molecule that increases platelet cAMP is prostaglandin I2<\/sub>10<\/sup>.<\/p>\n

Animal survivallance on this earth has been made acceptable only because of the important role played by plants. Medicinal plants are the plants or their parts used for the protecting the health care of an individual as they probably contains a large number of functional groups which shows therapeutic activity against various dysfunctions of organs or tissues or systems in the body. The future of the plants as sources of medicinal agents for use in investigation, prevention, and treatment of diseases is very promising. Herbal preparations contain a wide variety of chemical constituents like tannins, salicylate, and coumarins and proved as clot lysis or thrombolytic agents. Therefore herbal preparations would be used in the place of synthetic drugs to avoid unwanted effects.<\/p>\n\n\n\n

The present scenario in thrombolytic therapy<\/strong><\/p>\n

To get cleanse of problems developed due to the formation of a clot in the blood or thrombus to remodify function to the affected area, fibrinolytic therapy is required11<\/sup>. The agent which is having the thrombolytic activity also known as clot busters which shows long term benefits for survivors, who have just a 5 % death rate at one year12<\/sup>. Fibrinolytic substance is being used in blood vessels or venous thrombosis, pulmonary (lung) embolism, myocardial infarction formation of clot in the arteries (arterial thromboembolism), and acute ischemic strokeetc13<\/sup>.<\/p>\n

Contraindications for thrombolytic therapy<\/strong><\/p>\n

Thrombolytics were predominantly safe and effective in correcting thrombosis, but excessbleeding (hemorrhage) is the major adverse effect. The current epidemiological data stated that 11% of all diseased persons who were administered thrombolytics have presented adverse effects like hemorrhage. About 0.3-1.3% had significant adverse drug reactions like intracranial hemorrhage. These drugs are contraindicated in vascular lesions, severe uncontrolled hypertension, brain tumor, peptic ulcer and pregnancy.<\/p>\n

Methodology<\/strong><\/p>\n

Published articles in connection with thrombolytic activity of various herbal plants were retrieved from PubMed, Science Direct, Taylor and Francis, BMC, ACS, Google scholar, Web of Science, Scopus and other literature database. Some articles were found by tracking citations from publications. The research key words used were thrombolytic activity and herbal plants. In this review briefly discussed the recent scientific findings regarding the thrombolytic activities of various herbal plants and indicatedtheareas where further study is required. The literature collections were restricted to publications in English language.<\/p>\n

Conclusion <\/strong><\/p>\n

This review helps to understand the effect of various medicinal plants having thrombolytic activity. The accessibility of treating the thrombotic diseases with herbal medicine or plant derived compounds and not necessity of laborious pharmaceuticals synthesis seems that the approach is highly attractive. As per the presented data, many literature studies offered the thrombolytic importance of crude and\/or solvent extracts of the various plants parts. Though the thrombolytic property was proved in these investigations, further much attention and an extensive study is required in exploring the phytochemical and pharmacological profile of the active principles. It will be helpful to the pharmacologists, scientists and health professionals to develop new safer pharmaceutical products with thrombolytic properties.<\/p>\n
