Changes in Synovial Fluid N-Acetyl-β-Glucosaminidase Activity in the Human Temporomandibular Joint with Dysfunction

Changes in Synovial Fluid N-Acetyl-β-Glucosaminidase Activity in the Human Temporomandibular Joint with Dysfunction

β-Glycosidases (N-acetyl-β-glucosaminidase, N-acetyl-β-galactosaminidase, β-glucuronidase) were assayed in temporomandibular joint (TMJ) synovial fluid obtained from 23 patients with closed lock TMJ internal derangement (ID), four with closed-lock TMJ osteoarthritis (OA), and 13 with normal controls...

Zusammenfassung:β-Glycosidases (N-acetyl-β-glucosaminidase, N-acetyl-β-galactosaminidase, β-glucuronidase) were assayed in temporomandibular joint (TMJ) synovial fluid obtained from 23 patients with closed lock TMJ internal derangement (ID), four with closed-lock TMJ osteoarthritis (OA), and 13 with normal controls (N). Synovial fluid was collected from the upper joint space after injecting 1.5 ml of 1% lidocaine three times. The specific activity of N-acetyl-β-glucosaminidase increased significantly both with ID (p
