ABSTRACT
OBJECTIVE:
To evaluate the immunogenicity of bovine jugular vein conduits (BJVCs) treated with different cross-linking methods.METHODS:
The BJVCs were treated with glutaradehyde (GA), dye-mediated photooxidation (DMP) and polyepoxy compound (PC) (n = 10). The tissue homogenates obtained from BJVCs treated with PC, GA, DMP, and fresh BJVCs, were mixed with the complete Freand adjavant to form the emulsive antigen, which were used to immunize rabbits correspondently. The antibody concentrations to BJVCs in those rabbits' serum were measured by counter double immuno diffusion. The immunologic responses to the BJVCs in different groups were measured with Western blotting.RESULTS:
The positive bands appeared when the sera of rabbits were immunized by fresh BJVCs reacted with antigens of fresh BJVCs, but no bands appeared when the sera of rabbits were immunized by fresh BJVCs reacted with those antigens of the BJVCs treated with GA, DMP, and PC in Western blotting.CONCLUSION:
The immunogenicity of BJVCs treated with PC, DMP, and GA can be reduced significantly and meet the clinical standard.
