Abstract:
Objective:To investigate the expression of transforming growth factor ?1(TGF-?1) in dog mandibular distraction osteogenensis (DO). Methods: Mandibular DO model was established in 12 dogs and nonunion model in another 12 dogs, 4 dogs were used as the no-treatment control. Tissue samples were obtained 6 d,2 and 8 weeks after operation respectively.Immunohistochemistry and enzyme-linked immunosorbent assay (ELISA) were used to determine the expressions of TGF-?1 in the samples.Results: TGF-?1 (ng/g) in control group was 1394.3?20.1,6 d after operation that in DO and nonunion groups was 1928.5?33.5(vs control,P
