The advantages of bovine jugular vein tanned with hydrophilia crosslinking agent / 生物医学工程学杂志

The bovine jugular veins were divided into two groups and treated with 4% EX-313 and 0.5% glutaraldehyde respectively, and then they were examined with naked-eye, microscope and scanning electron microscope. Biomechnics test and dorsal implantation in rats were performed. The aquired data were processed and subjected to t-test. The EX-313 fixed material was more pliable than the glutaraldehyde treated material, and the former had higher anticalcification than the latter. In conclusion, the hydrophilia crosslinking agent EX-313 is superior to glutaraldehyde in treating biomaterials, and the bovine jugular vein tanned with EX-313 should be a promising material for repairing in cardiovascular surgery.
