Cysteine proteinase procoagulant from amnion-chorion

Cysteine proteinase procoagulant from amnion-chorion.

Various coagulation abnormalities are associated with pregnancy. Several investigators have suggested that there may be a unique procoagulant associated with amniotic tissue and fluid. We identified a cysteine proteinase from malignant tissue, cancer procoagulant, and had reason to believe a similar proteinase may be present in amniotic tissue. Amniotic fluid and extracts of amnion-chorion were...

Antibacterial properties of human amnion and chorion in vitro.

OBJECTIVE The purpose of the present study was to explore the direct effects of amnion and chorion on bacterial growth in vitro including the antibacterial spectrum. Chorioamniotic membranes were obtained under sterile conditions from 13 healthy women undergoing elective cesarean section at term. Likewise, chorioamniotic membranes were obtained from 10 healthy women with spontaneous vaginal del...

Amnion/chorion grafts and their applications in urology

tau.amegroups.com © Translational Andrology and Urology. All rights reserved. The use of human amnion/chorion membranes in wound healing and skin grafting dates back to the early 1900s (1-4). Widespread use of these graft materials has been limited by concerns with sourcing, storage, preparation, and the potential for transmission of infectious diseases (including hepatitis C) (4). Recent devel...

Some properties of a cysteine proteinase inhibitor from corn endosperm.

Thougha numberof proteinaceous cysteine proteinase inhibitors (cystatins) of animal origin have long been studied in detail,1* little is well-defined about plant cystatins except for oryzacystatins from rice seeds.2'3) Preceding the studies on oryzacystatins, however, we purified a cysteine proteinase inhibitor from corn.4'5) In this study we carried out amino acid analysis and kinetic studies ...
