- Abstract
Purpose: The purpose of this study was to study the protective effect and influence of sodium hyaluronate (Na- HA) on mRNA expression of peroxisome proliferators-activated receptor gamma (PPAR-γ) in cartilage of rabbit osteoarthritis (OA) model. Materials and Methods: Forty eight white rabbits were randomly divided into A, B, and C groups. Group A was normal control group, B and C groups underwent unilateral anterior cruciate ligament transection (ACLT). The rabbits in group B were injected normal saline after ACLT; and Group C received intraarticular1% sodium hyaluronate (HA) injection 5 weeks after surgery, 0.3 mL once a week. At 11th week after surgery, all the rabbits were sacrificed. The cartilage changes on the medial femoral condyles were graded separately. Cartilage sections were stained with safranin-O and HE, and messenger RNA (mRNA) expression of PPAR-γ was detected by using real time polymerase chain reaction (Real Time-PCR). Results: Cartilage degeneration in group B was significantly more severe than in A and C injection group. The grey value of Safranin- O of B group was higher than A and C groups. Expression of PPAR-γ mRNA in group B was higher than group A and C. Conclusion: This study shows that Na-HA has a protective effect on articular cartilage degeneration, and the inhibitory effect on the PPAR-γ mRNA expression may be one of therapeutic mechanism of Na-HA.
