[Effect of antihypertensive drugs on some humoral parameters of endothelial function].
We assessed effect of antihypertensive drugs from various classes on humoral parameters of endothelial function - levels of asymmetrical dimethyl-arginine (ADMA) and metabolites of nitrous oxide (MNO) - in 106 patients with I-II degree arterial hypertension before and after 2 weeks of treatment. Two weeks treatment ...

[Comparative assessment of a calcium antagonist with controlled release of nifedipine and enalapril in arterial hypertension in subjects older than 60 years].
We compared antihypertensive effects and organoprotective action of a calcium antagonist nifedipine RD and angiotensin converting enzyme (ACE) inhibitor enalapril in subjects older than 60 years with systolic diastolic (group 1) and isolated (group 2) I-II degree arterial hypertension. Subgroups of patients receivi...

[Action of a nitric oxide donor dinitrosyl complex of iron with glutathione on hemodynamics in rats and monkeys].
We studied action of a nitric oxide donor, dinitrosyl complex of iron (DNIC) with glutathione as a ligand on the hemodynamics of normotensive Wistar rats, spontaneously hypertensive rats (SHR), and monkeys. Intravenous DNIC introduction (2-120 mg/kg) rendered fast (1-2 min) hypotensive effect combined with increase...
