Key result
NOS inhibition with L-NAME selectively reduced plasma volume in pregnant rats (4.5 vs 6.8 mL/100 g; P<0.05), mimicking a major pathophysiological perturbation of preeclampsia.
Why the study?
Does NOS inhibition with L-NAME alter plasma volume and hormonal regulation in pregnant rats?
Does NOS inhibition with L-NAME alter plasma volume and hormonal regulation in pregnant rats?
Absolute Event Rate: 4.5% vs 6.8%
p-value: p=<0.05
NOS inhibition in pregnant rats selectively reduces plasma volume, mimicking a major pathophysiological perturbation of preeclampsia, but does not induce its characteristic hormonal changes.

Hypothesis-generating for preeclampsia volume dysregulation; leaves open human translation and therapeutic targeting of NOS.
Zhang et al. (2000) studied Pregnancy. Nω-nitro-L-arginine methyl ester (L-NAME) vs. D-NAME was evaluated on Plasma volume in pregnant rats (p=<0.05). NOS inhibition with L-NAME selectively reduced plasma volume in pregnant rats (4.5 vs 6.8 mL/100 g; P<0.05), mimicking a major pathophysiological perturbation of preeclampsia.
