Evidence for new spasmogenic substances released by trypsin from plasma of normotensive and hypertensive rats.

We have extended our previous study of increased levels of new spasmogenic substances released by trypsin from the plasma of chronic one-kidney, one-clip hypertensive rats by describing preparative procedures utilizing Sephadex G-25, CM-cellulose and C18 reverse-phase HPLC for their partial purification. We demonstrate the existence of at least 6 HPLC components, distinguishable from bradykinin, bradykinin homologues having Lys before Arg1 of bradykinin and T-kinin (Ile-Ser-bradykinin) on the basis of their chromatographic properties. Several of these spasmogenic substances induce a very slow contraction of the isolated guinea pig ileum when compared to bradykinin.[1]
