Abstract
The effects of nitric oxide (NO, 10-6 M) on contractility and intracellular calcium
level ([Na2+].) of rat tail artery smooth muscles in control and under inhibition of soluble
guanylate cyclase (sGC) with 6-anilino-5,8-quinolinedione (LY83583, 10-6 M) are
investigated. NO-induced relaxations of vascular smooth muscles comprised
61,01 ± 5,56% of maximum induced amplitude of K+-contracture, and decreases in
[Ca2+]i comprised 66,35 ± 11,33%. Under the inhibition of sGC with LY83583
NO-induced relaxations of vascular smooth muscles comprised 29,41 ± 5,17% of
maximum induced amplitude of K+-contracture, and decreases in [Ca2+]i comprised
53,68 ± 16,93%. Thus, cGMP-independent relaxation of vascular smooth muscle and
decrease in [Na2+]. of rat tail artery is confirmed.
