Elevated bradykinin receptor type 1 expression in postpartum acute myometritis: Possible involvement in augmented interstitial edema of the atonic gravid uterus.

We demonstrated the up-regulated expression of B1R in the myometrium and its positive correlation with histologically estimated interstitial edema, suggesting the contribution of the kinin-kallikrein-B1R system to the development of interstitial edema in PAM cases.
