RESUMEN
Objective To study the anti-calcification function properties of bovine jugular conduit with valves stabilized by dye-mediated photooxidation.Methods Sixteen bovine jugular conduit with valves were divided into two groups and treated with dye-mediated photooxidation(groupⅠ) and glutaraldehyde(group Ⅱ).The bovine jugular vein was cut into pieces and implanted subcutaneously in the 16 weanling SD rats.After 90 days,all the rats were sacrificed and the retrieved specimens were undergone histological examination by electron microscope and microscope.The calcium content was determined by flame atomic absorption spectrophotometer.Results The walls and valves of bovine jugular vein treated by dye-mediated photooxidation had less calcification than those of the group Ⅱ.Conclusion The dye-mediated photooxidation can effectively preserve the calcification of bovine jugular conduit with valves compared with the way treated by glutaraldehyde.
