since we found that d-pro-phe-arg-pna is a potent inhibitor of the bradykinin induced contractile action of isolated smooth muscle preparations such as the guinea pig ileum and rat uterus , we screened d-pro-phe-arg-s-ch2-c6h5 at a 5 x 10 ( -5 ) m and found that it completely blocked the bradykinin ( 1 ng ) induced contraction of the isolated rat uterus preparation .
