background: perioglasâ (pg) is an alloplastic material used for grafting periodontal osseous defects since 1995. in animal models, it has been proven that pg achieves histologically good repair of surgically created defects. in clinical trials, pg was effective as an adjunct to conventional surgery in the treatment of intrabony defects. because the molecular events due to pg that are able to al...
the gamma irradiation has been used for end sterilization of allograft bones and its effects with a 25 kgy dosage on the osteoinductive properties of demineralized bone allograft powder was studied. this work carried out using an experimental method in an animal model. in this study the demineralized bone allograft powder which had been sterilized and prepared with gamma irradiation in a 25 kgy...
BACKGROUND Allograft survival among black recipients is poorer than among whites. Delayed allograft function is associated with a significant reduction in renal allograft survival. The relationship between delayed allograft function and black race is incompletely specified and was the focus of this investigation. METHODS A non-concurrent study of 325 recipients of cadaveric allografts followe...
Background: The Presence of donor leukocytes in recipients of organ allograft has been shown even several years after transplantation. However, it remains unclear whether this donor cell microchimerism plays an effective role in allograft acceptance or is simply a consequence of immunosuppressive conditions in recipients. Objective: To study microchimerism in a group of kidney transplant recipi...
Background: Correlations between bone marrow, heart, kidney, liver, skin and lung transplant rejection or survival with human cytokine gene polymorphisms have been described. There are also reports about the role of cytokines and Tumor Necrosis Factors-Alpha (TNF-α) on corneal transplant in animal models. Further studies are needed to clarify the role of cytokines in corneal allograft rejection...
BACKGROUND To report a case with hypotony due to late leakage of the filtering bleb performed during childhood and treated surgically using human pericardium graft. CASE PRESENTATION A man with hypotony related to bleb's leakage in his right eye was presented. During his childhood trabeculectomy was performed to manage ocular hypertension due to pediatric glaucoma. Biomicroscopy revealed chor...
Granulomatosis with polyangiitis is a systemic disease resulting in necrotizing vasculitis of small- and medium-sized vessels. Cardiac involvement is rare and when present usually manifests with pericarditis and coronary artery vasculitis. We report here a case of granulomatosis with polyangiitis involving the native coronary arteries, bypass graft, and pericardium with interesting imaging find...
OBJECTIVE To evaluate the effect of gamma irradiation on glutaraldehyde-fixed bovine pericardium. METHOD Glutaraldehyde-fixed bovine pericardium was exposed to gamma radiation (doses from 0 to 10000 Gy). Six samples from each of nine groups were evaluated by optic microscopy, and shrinking and mechanical tests and the denaturation temperature was determined. Additionally, they were subcutaneo...
To elucidate the pathophysiology of severe right ventricular infarction (RVI), isolated RVI was produced in 15 dogs with the pericardium intact or open. After RVI in dogs with the pericardium intact, RV systolic pressure decreased by 27%, aortic pressure by 29% and cardiac output by 34%. RV transmural pressure, RV end-diastolic size and intrapericardial pressure increased, left ventricular tran...
urulent pericarditis caused by Staphylococcus aureus is an infrequent complication of infections originating in another body location. It is typically an acute and often catastrophic illness. In this report a 23-year-old man presented to accident and emergency department with fever, productive cough and chest pain of 5 days duration, followed by shortness of breath. Chest x-ray showed air fluid...
