    Abstract

    Recent studies effected by our Institute indicate that various forms of human arthritis express both immunohistochemically and biologically active nerve growth factor (NGF) in the synovium. In the present study, we used a model of carrageenan-induced arthritis to further evaluate the effects of joint inflammation on NGF level. These studies showed that experimentally-induced arthritis in rats caused a significant increase in NGF in the perivascular area of the synovium. We also showed that injection into the synovium of purified NGF did not cause inflammation per se and that the destruction of peripheral sympathetic innervation significantly reduced both the inflammation and the level of NGF following carrageenan injection.
