For example, the patient can be to cells. This is critical because the pharmacological efficacy administered an antioxidant and a nitric oxide donor, or the of NO depends upon the form in which it is delivered. In patient can be administered an antioxidant and a nitrosated contrast to the nitric oxide radical (NOo), nitrosonium (NO") compound.

Patients were considered to be salt-sensitive if mean blood pressure was at least 10 mm Hg higher during the 0191). As described herein, NO deficiency is a central salt loading period (Weinberger etal, Hypertension, 8: II-127 pathophysiologic mechanism for the black vascular diathesis. II-134 (1986)). As shown in FIGS. 4A-B, there were trends To examine this issue in forearm microVessels, the vasodila for impaired vasodilator responses to both methacholine tor responses to intra-arterial infusions of methacholine, Sodium nitroprusside, and were examined using (FIG. 4A) and sodium nitroprusside (FIG. 4B).

These data show factors, such as Smoking, diabetes mellitus, or hypercholes impaired NO action in the microvasculature of salt sensitive terolemia, and the two groups were matched in terms of age, individuals prior to the development of hypertension. gender, lipid levels, blood pressure, and anti-hypertensive treatment. Similar to previous reports (Lang et al., N Engl J Example 4 Med, 333:155-160 (1995); Panza etal, NEngl.JMed, 323:22 27 (1990)), the dilator response to methacholine, but not 0194 The effects of hypertension and race on conduit nitroprusside, was significantly reduced in these hypertensive vessel function were examined using a well-established bra patients compared to age-matched normotensive controls chial ultrasound technique (Vita et al.

As shown in Table 1, there hypertensive patients compared to white hypertensive were no significant differences in flow-mediated dilation or patients.
