objective :To research the relation between the bone joint degeneration and the activity of the Alkaline phosphatase (ALP) .

Experimental Studies on Repairing Articular Cartilage Degeneration with Glucosamine Sulphate and aFGF in Rabbits with Osteoarthritis;

In order to investigate the prophylactic effects of intra-articular injection of Radix Salviae MiltioiThizae(RSM) and Sodium Hyaluronate (SH) on cartilage degeneration and cartilage cell apoptosis of osteoarthritis(OA), 37 healthy adult Japanese rabbits were divided randomly into 4 groups: 9 for Group A injected physiological saline 0.

Many studies have proved that the subchondral bone plays an important role in the development of osteoarthritis,and may be the initial factor of the disease,but the exact relationship between articular cartilage degeneration and subchondral bone sclerosis is still unclear.
