since cat ileum desensitized with bk or lys-bk shows a significant decrease or a complete disappearance of the response to the other agent , while maintaining full sensitivity for histamine , and since the pa2 values of [ leu-ome8 , des-arg9 ] -bk against bk and lys-bk are identical in the rabbit aorta , we conclude that the two kinins act on the same types of receptors .
