Abstract:
[Objective]To observe expression of inducible nitric oxide synthase and peroxynitrite anion around the prostheses,and study the relationship between the osteolysis and inducible nitric oxide synthase peroxyni-trite.[Method]Interface tissues were obtained at three Delee-Charnley acetabular sections and seven Gruen femur sections in six revision total hip arthroplasty surgery. The tissues were prepared for immunohistochemical assays to determine the expression of iNOS and nit rotyrosine (NT)-a specific“footprint”of peroxynitrite. Pre-revision X-ray films were observed to determine the incidence of osteolysis regions and non-osteolysis regions. The correlation between the positive cells and the severity of osteolysis were analyzed and compared.[Result]Data showed that zone Ⅲ has much higher iNOS positive immunostaining than that of zone Ⅰ and Ⅱ at acetabulum, and the expression of zone 1、2、6、7 was significantly higher than the other zone at femur(P
