to examine if these responses are mediated by different neurokinin receptors , we studied the mechanical response and the release of [ 3h ] acetylcholine from antral muscle strips in response to sp , substance p methylester ( spme ) , neurokinin a ( nka ) , neurokinin b ( nkb ) , and several non-mammalian tachykinins .
