Abstract:
Expression of endogenous ouabain in placenta and the concentrations of serum ET-1 and NO were examined in 30 patients with hypertensive disorder complicating pregnancy (HDCP) and 30 healthy pregnant women to investigate the effect of endogenous ouabain on HDCP. Compared with the healthy pregnant group, the expression of endogenous ouabain dramatically increased in the HDCP groups (P<0.01). There was a significantly positive correlation between the expression of en- dogenous ouabain with ET-1 (r=0.5567, P<0.01), while the correlation of endogenous ouabain and NO was significantly negative (r=-0.6895, P<0.01). As expected, the correlation between ET-1 and NO was negative (r=-0.7796, P<0.01). ET-1 concentrations of maternal and cord sera in HDCP groups were significantly higher in comparison with healthy pregnant group (P<0.01). On the con- trast, NO concentrations were much lower in the maternal and cord sera of HDCP groups as com- pared with healthy pregnant group (P<0.01). Our data suggest that endogenous ouabain is directly involved in the nosogenesis of HDCP, with accompanying decreased NO and the elevated of ET-1.
