2001 JUL 5 - (NewsRx Network) -- Researchers have identified reduced blood levels of available nitric oxide as a cause of preeclampsia, according to a report in the June 8, 2001, issue of Circulation Research, a journal of the American Heart Association.
Preeclampsia is a major cause of severe complications and death for both mother and newborn. Nitric oxide (NO) is produced by the blood vessels and helps the vessels relax, which eases blood pressure.
Researchers took blood samples from 21 pregnant women with preeclampsia and 21 women with normal pregnancies. Those with preeclampsia had elevated blood levels of S-nitrosothiols, substances that act as a major reservoir of releasable NO, which means NO was not being released. The levels of S-nitrosothiols were 294 picomole per milligram (pmol/mg) of protein in women with preeclampsia vs. 186 pmol/mg in those with ...
