The aim of this study was to investigate the effect of hyaluronic acid (HA) on the expression of osteopontin (OPN) and CD44 mRNA of fibroblast-like synoviocytes (FLS) in the patients with osteoarthritis (OA) of the knee. FLS were obtained from the knees of 10 patients with OA. Real-time quantitative polymerase chain reaction (Q-PCR) was used to assess the expression of the OPN mRNA and CD44 mRNA.

Background: Many studies have identified smoking as a risk factor for osteoporosis, but it is unclear whether passive smoking has an effect on bone mineral density and bone turnover and if such an effect could cause osteoporosis.The purpose of the study was to investigate the effect of passive smoking on bone mineral density (BMD) and bone turnover and the relationship between BMD and bone turnover in female rat.
Methods: Forty-eight female Wistar rats were randomized into six groups: 2-month, 3-month,4-month smoke-exposed rats and their controls.
