Bioprotein glue combined with gelatin sponge for prevention of epidural adhesions after surgical operation / 基础医学与临床

Objective To prove the prophylactic function of absorbable gelatin sponge and bioprotein glue for prevention of epidural and nerve root scar adhesions after laminectomy. Methods We excised the L6 vertebral plates of 36 adult New Zealand male rabbits,to make vertebral plate excision model and to find nerve root. Then divided them into 3 groups based on different materials:gelatin sponge and bioproten glue (group A),gelatin sponge (group B) and saline solution (group C). The morphological changes of the scars were observed grossly and histologically at 2 and 8 weeks after operation. We also measured the orbit of the nerve root. Results Gelatin sponge combining with bioprotein glue can reduce adhesion obviously(P
