Definition: Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Input: To search tools of high blood pressure in the model of nitric oxide (NO)-defective hypertension, and the study focused on the effect of rilmenidine, agonist of imidazoline receptors, which was suggested to modulate central sympathetic outflow.', 'Three experimental groups, each consisting of 7 rats, were used: (I) rats with inhibition of NO synthase (NOS) by N(G)-nitro-L-arginine methyl ester (L-NAME) 40 mg.kg(-1).d(-1) for 4 weeks in drinking water, (II) rats with inhibited NOS as in group I , plus agonist of imidazoline receptors rilmenidine 3 mg.kg(-1).d(-1) for 4 weeks by gavage, and (III) control rats. Systolic blood pressure was measured weekly noninvasively. At the end of experiment aortic ring isometric tension was followed, NOS expression (aorta, left ventricle), and NOS activity (left ventricle and brain) were determined.', 'In the group I systolic blood pressure increased significantly, aortic ring relaxation to acetylcholine was significantly attenuated. Rilmenidine administered simultaneously with L-NAME (group II) prevented the increase of blood pressure which did not differ significantly from control values; aortic ring relaxation to acetylcholine did not differ from control. No change in NOS expression (aorta and left ventricle) was found in groups I and II. Significant decline in NOS activity (left ventricle and brain) was found in groups I and II.
Output:
Does rilmenidine prevent blood pressure increase in rats with compromised nitric oxide production?
