Abstract
Substance P immunoreactive (SP-IR) nerve fibres were identified using fluorescence immunohistochemistry and the length of the labelled individual nerve fibres was measured using confocal microscopy of whole mounts of the lateral wall of the ankle joint in 2-week-old domestic chicks. In the normal ankle there was an extensive network of SP-IR fibres in the synovial and subsynovial tissue of the joint capsule. Fours hours after injection of sodium urate into the joint space the joint was inflamed and there was a significant reduction in the labelled nerve fibres. These results demonstrate experimentally that painful gouty arthritis produces a neurogenic depletion of substance P from peripheral nerve fibres in the synovial and subsynovial tissue.
