Experimental Model of Zymosan-Induced Arthritis in the Rat Temporomandibular Joint: Role of Nitric Oxide and Neutrophils
Figure 5
Photomicrographs of the immunostaining for iNOS in the TMJ and periarticular tissues of zymosan-induced TMJ arthritis in rats. (a) Negative control (sections in the absence of anti-iNOS antibody) of arthritic rats (100x). (b) Normal rat TMJ showing light immunostaining for iNOS (100x). (c) TMJ arthritis induced by zymosan 2 mg showing strong immunostaining for iNOS in chondrocytes and synoviocytes (100x).
