Systolic blood pressure (sBP) was measured weekly by the plethysmographic method. For morphological studies, the animals (n=10) were perfused with a fixative (120 mm Hg), and thoracic aorta and carotid and coronary arteries were processed for electron microscopy. For functional investigation (n=10), aortic rings were used in an organ bath. In Wistar rats, L-NAME evoked an increase of sBP; hypertrophy of the heart and arterial walls; an increase in cross-sectional areas (CSA) of endothelial cells (EC), muscle cells (SMC), extracellular matrix (ECM), and\u00a0a\u00a0decrease in acetylcholine-induced endothelial-dependent relaxation (EDR). 7NI evoked sBP-independent hypotrophy of the heart and arterial walls, a decrease in CSA of EC and SMC without affecting the CSA of ECM, and a mild decrease in acetylcholine-induced EDR. 7NI and L-NAME administered together evoked lower effect on BP and trophicity of the heart and all arteries, and a similar decrease in acetylcholine-induced EDR compared to L-NAME alone. In SHR, 7NI did not evoke any effect on the studied parameters.<\/jats:p>","DOI":"10.33549\/physiolres.932777","type":"journal-article","created":{"date-parts":[[2020,4,6]],"date-time":"2020-04-06T07:17:19Z","timestamp":1586157439000},"page":"1-10","source":"Crossref","is-referenced-by-count":3,"title":["Different Effects of 7-nitroindazole and L-NAME Administered Both Individually and Together on the Cardiovascular System of the Rat"],"prefix":"10.33549","author":[{"given":"F.","family":"KRISTEK","sequence":"first","affiliation":[{"name":"Institute of Normal and Pathological Physiology, Centre of Excellence for Examination of Regulatory Role of Nitric Oxide in Civilisation Diseases, Slovak Academy of Sciences, Bratislava, Slovak Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"DROBNA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"CACANYIOVA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"19169","published-online":{"date-parts":[[2015,2,15]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"BACHHAV SS, BHUTADA MS, PATIL SD, BASER B, CHAUDHARI KB: Effect of Viscum articulatum Burm.
