Study of Different "Fibrinoids" by Histochemical Means.

Abstract

The types of "fibrinoids''* in different pathological processes were studied by means of specific staining reactions and histochemical procedures intended to block amino groups. All fibrinoids differed from fibrin in their behavior. The "fibrin" layer around the placental villi behaved more like fibrin than any other "fibrinoids". The other "fibrinoids" differed markedly from each other and from fibrin. It may be concluded that in spite of their tinctorial similarities, the various "fibrinoids" contain different compounds and might represent the end-stages of different processes.
