ABSTRACT

Objective To detect the pathological expressions of TNF-? and VEGF in interspinous ligament of patients with ankylosing spondylitis(AS) in active stage. Methods The expressions of TNF-? mRNA and VEGF mRNA in the interspinous ligament of patient with AS group and control group were detected by hybridization in situ. Their different results were compared by image analysis system and the correlation between TNF-? mRNA, VEGF mRNA and both AS disease active index (DAI) and C reactive protein (CRP) was analysed respectively. Results The expressions of TNF-? mRNA and VEGF mRNA in the interspinous ligament of patients with active AS were positive,but those of the control group were negtive. Statistical differences existed in the positive cell numbers and in image gray scale value of AS group (P
