To assess the sensitizing effect of SP on articular afferent fibres the NK<jats:sub>1<\/jats:sub>receptor antagonist RP 67580 was applied in normal and acutely inflamed rat knee joints.<\/jats:p><jats:p>Altogether 38 fine afferent nerve fibres from the rat knee with conduction velocities of 0.71\u201313.5\u2008m\/s were recorded as single units, during non\u2010noxious and noxious joint rotations. SP, injected i.a. as a bolus close to the knee joint, was able to sensitize 45.5% (10 of 22) of the units recorded from normal joints and 33.3% (five of 15) of afferents from inflamed joints. The following i.a. application of RP 67580 in a range of 20\u2013200 nmol antagonized in a dose\u2010dependent manner the sensitizing effect of SP in a large proportion of slowly conducting articular afferents from normal (66.7%) and inflamed (46.2%) knee joints. Subsequent SP application enhanced the afferent sensitivity further. The electrophysiological results presented here further support the suggestion that the sensitization of afferents by SP in the rat knee joint is mediated mainly by the NK<jats:sub>1<\/jats:sub>receptor, which is probably located on the primary afferents.<\/jats:p>","DOI":"10.1053\/eujp.2000.0222","type":"journal-article","created":{"date-parts":[[2002,9,10]],"date-time":"2002-09-10T15:03:34Z","timestamp":1031670214000},"page":"69-79","source":"Crossref","is-referenced-by-count":13,"title":["The neurokinin\u20101 receptor antagonist RP 67580 reduces the sensitization of primary afferents by substance P in the rat"],"prefix":"10.1002","volume":"5","author":[{"given":"Matthias","family":"Pawlak","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert F.","family":"Schmidt","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernd","family":"Heppelmann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ulrike","family":"Hanesch","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,1,9]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0169-328X(95)00244-M"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0304-3940(93)90071-R"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0006-8993(96)00619-1"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1476-5381.1993.tb13708.x"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1476-5381.1996.tb15664.x"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1159\/000138190"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00506259"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/0167-0115(93)90066-H"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1982.sp014347"},{"key":"e_1_2_1_11_1","doi-asserted-by":"crossref","first-page":"25668","DOI":"10.1016\/S0021-9258(18)35658-8","article-title":"Molecular basis for the species selectivity of the neurokinin\u20101 receptor","volume":"267","author":"Fong T.M.","year":"1992","journal-title":"J Biol Chem"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.88.22.10208"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0014-2999(97)01581-1"},{"key":"e_1_2_1_14_1","first-page":"59","volume-title":"Proceedings of the Fifth World Congress on Pain","author":"Handwerker H.
