Preeclamptic cord blood hemolysis and the effect of Monascus purpureus and Saccharomyces cerevisiae in modulating preeclamptic stress

Abstract

Preeclampsia is associated with impaired antioxidant defense that results in materno- fetal complications. In addition to antioxidant deficiency, hemolytic disorder has also been observed in preeclamptic mother. This study aims in analyzing the fetal complications using cord blood RBC (red blood cell); further the antihemolytic and antioxidant efficiency of two common probiotic yeasts Monascus purpureus and Saccharomyces cerevisiae in preeclamptic and normotensive RBCs were assessed. There was a significant decrease in the antioxidant status (p<0.05) with increased oxidative stress, nitrative stress (p<0.05) and hemolysis (p<0.001) in preeclamptic RBC comparatively. M. purpureus demonstrated a highly significant reactive oxygen radical scavenging activity (p<0.001) whereas S. cerevisiae exhibited a highly significant nitric oxide radical scavenging activity (p<0.001). It was noted that oxidative stress hemolysis was decreased with increased antioxidant level in cord blood RBC from both samples after incubation with both yeasts in a similar manner. The antihemolytic property of M. purpureus and S. cerevisiae suggests that S. cerevisiae functions efficiently with increasing stress. This study demonstrates for the first time that despite their differential scavenging activities, a diet rich in M. purpureus and S. cerevisiae could equally serve as a good natural supplement to alleviate the stress status in the preeclamptic fetus (Tab. 4, Fig. 1, Ref. 39).
