Figure 1From: Activation of voltage-gated KCNQ/Kv7 channels by anticonvulsant retigabine attenuates mechanical allodynia of inflammatory temporomandibular joint in rats Histopathologic examination of inflammatory TMJ region induced by CFA in rats. A. Photomicrograph of TMJ 24 hours after injection of saline as a normal control. B. Photomicrograph of TMJ 24 hours after injection of CFA. Exuberant hypertrophy of the synovial tissue, angiogenesis in the enlarged area (indicated by arrowhead) and fibrin-like exudates (indicated by arrow) in the joint space were observed (Magnification × 4, scale bar = 200 μm).Back to article page
