[Correction of endothelial dysfunction by L-arginine under experimental pre-eclampsia conditions].

The ADMA-like pre-eclampsia in pregnant rats was modeled by daily introduction of L-NAME in a dose of 25 mg/kg for 7 days. L-arginine (200 mg/kg) prevented the development of arterial hypertension and a decrease in placentary microcirculation and microalbuminuria. The possibility of using L-arginine for the prevention of competitive eNOS inhibition by ADMA is discussed.
