We and others have previously observed an imbalance in cytotrophoblast secretion of the vasoactive prostanoids prostacyclin and thromboxane A(2) in pre-eclampsia. To examine the effects of potential modulators of this imbalance, cytotrophoblasts isolated from normal and pre-eclamptic pregnancies were incubated in the presence of lipopolysaccharide, the(More)
Villous trophoblasts isolated from term placentae of normal pregnancies, and pregnancies complicated by chronic hypertension or pre-eclampsia, were examined over 7 days in primary culture. Low levels of prostaglandin E2 and prostacyclin (measured as 6-keto prostaglandin Fl alpha) were secreted by trophoblast cells from all three clinical groups. Secretion(More)
OBJECTIVE This study was conducted (1) to determine in vitro placental villous cytotrophoblast secretion of prostacyclin, prostaglandin E2, and endothelin-1, (2) to examine the effect of serum from normal and preeclamptic women on secretion of these vasoactive substances, and (3) to determine whether responses to these sera by cytotrophoblasts from(More)
OBJECTIVE To screen the activated fraction from Celastrus aculeatus and study its effect on T lymphocyte apoptosis. METHODS Different polarity fractions were isolated from Celastrus aculeatus extract. Flow Cytometry method was used to detect apoptosis ratio of the active fractions. RESULTS Different fractions extract from Celastrus aculeatus and GSF-A(More)
