bradykinin derivatives with increasing molecular weights ( lysyl-bk ( l-bk ) , methionyl-lysyl-bk ( ml-bk ) and glycyl-arginyl-methionyl-lysyl-bk ( gaml-bk ) ) were found to produce effects of decreasing intensity on the threshold of electrical stimulation according to the following scale : bk ( 1.00 ) > l-bk ( 0.28 ) > ml-bk ( 0.060 ) > gaml-bk ( 0.047 ) .3 .
