Anti-calcifying treatment of glutaraldehyde fixed bovine pericardium: comparisons and evaluation of possible synergic effects
Objective: To evaluate a possible synergic effect of the most promising anti-calcifying agents investigated in the literature by sequential treatment. Method: Glutaraldehyde-fixed bovine pericardium was treated by: heating to 50o C, 80% ether, 0.125% chitosan, heparin, NaBH4 and 4% formaldehyde. Samples were evaluated by optic microscopy, shrinking and mechanical tests and implanted subcutaneou...
متن کاملEffects of gamma irradiation on mechanical behavior and calcification of glutaraldehyde-fixed bovine pericardium.
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...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Polyethylene glycol-grafted bovine pericardium: a novel hybrid tissue resistant to calcification.
Calcification is a frequent cause of the clinical failure of bioprosthetic heart valves fabricated from glutaraldehyde pretreated bovine pericardium (GATBP). An investigation was made of the grafting of different molecular weight polyethylene glycol (PEG 600, 1500, 4000 and 6000) via glutaraldehyde (GA) linkages to bovine pericardium (BP) and of their stability and calcification. The process of...
