In chronic wounds, macrophage activation is suppressed which leads to an inappropriate growth factor response causing failure of positive autocrine feedback loop which normally controls the healing process. The regular application of exogenous PRP and Thrombin, to chronic wounds, restores the autocrine feedback loop of tissue repair which appears to accelerate the normal cascade of tissue repair\n\nObjectives\n\n* To evaluate the safety and tolerability of PRP/Thrombin mixture in treating chronic venous ulcers\n* To evaluate efficacy of PRP/Thrombin mixture in treating chronic venous ulcers'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Willing and able to give written informed consent\n* Age 18 years to 75 years.\n* Both males and females.\n* Ankle branchial index of 0.8 or above.\n\nExclusion Criteria:\n\n* Diabetics will be excluded as the Ankle Branchial Index (ABI) result is considered an unreliable due the possible presence of arteriosclerotic plaques (lead pipe rigidity).\n* Patients who have participated in experimental drug studies within 30 days of entering this study.\n* receiving chemotherapy or radiotherapy for malignant diseases or any other indication\n* Patients taking corticosteroids or other immunosuppressive medications\n* Clinically malnourished patients or those with recent (last 4 weeks without treatment) serum albumin of less than 30g/l.\n* Patients with current or past history of acute deep vein thrombosis.\n* Patients with current signs and/or symptoms of cardiac, renal or hepatic failure.
