Nitric oxide and malondialdehyde levels in healhty normotensive subjects and hypertensive patients

Nitric oxide modulates tissue plasminogen activator release in normotensive subjects and hypertensive patients.

We evaluated the possible role of NO in modulating tissue plasminogen activator (t-PA) release in the forearm microcirculation of normotensive subjects and hypertensive patients. Essential hypertensive patients are characterized by endothelial dysfunction because of a reduced NO availability and also show an impaired t-PA release. In healthy volunteers and essential hypertensive patients, we st...

Effect of enalapril on exhaled nitric oxide in normotensive and hypertensive subjects.

We investigated whether an angiotensin-converting enzyme (ACE) inhibitor increases the production of nitric oxide (NO) in exhaled air in normotensive and hypertensive subjects. In study 1, 8 normotensive male subjects received a single oral dose of enalapril (5 mg) or nitrendipine (10 mg) in a crossover manner. Exhaled air was collected at baseline, and at 2, 4, and 8 hours after administration...

Effects of Dietary l-Arginine on Nitric Oxide Bioavailability in Obese Normotensive and Obese Hypertensive Subjects

Obesity related hypertension is a major risk factor for resistant hypertension. We do not completely understand the mechanism(s) underlying the development of obesity related hypertension which hinders the development of novel treatment strategies for this condition. Data from experimental studies and small clinical trials indicate that transport of l-arginine, the substrate for nitric oxide (N...

Autonomic Function in Hypertensive and Normotensive Subjects

Malondialdehyde, glutathione, and nitric oxide levels in Toxoplasma gondii seropositive patients.

The aim of this study was to investigate the difference in the serum malondialdehyde (MDA), glutathione (GSH), and nitric oxide (NO) levels between normal and T. gondii-infected patients. To this end, MDA, GSH, and NO levels in the sera of 37 seropositive patients and 40 participants in the control group were evaluated. In Toxoplasma ELISA, IgG results of the patient group were 1,013.0 +/- 543....
