Experiments on isolated segments of the tail artery from young (aged 4-6 weeks) rats addressed the effects of noradrenaline (0.01-1.0 microM) on the reactions of these segments to stimulation with an electric field in isometric conditions. These studies showed that noradrenaline increases this reaction after spontaneous or acidosis (pH 6.6)-induced(More)
In vitro experiments on segments of the tail artery of young Wistar rats addressed the influence of noradrenaline (0.03–1.0 μM) on neurogenic constriction of these segments evoked by electric field stimulation in conditions of a reduction in perfusate pH from 7.4 to 6.6 or perfusate temperature from 36 to 25°C. Noradrenaline was found to potentiate(More)
Experiments using segments of the tail artery from young rats addressed the effects of noradrenaline on the neurogenic vasoconstrictor reactions of these segments evoked by stimulation with an electric field of frequencies 3, 5, 10, and 40 Hz in controls and after decreasing the solution pH from 7.4 to 6.6. Acidosis produced significant decreases in this(More)
The effect of melatonin on neurogenic reactivity of the juvenile rat tail artery segment was studied. The electrical field stimulation-evoked contraction of the segment decreased in the course of the experiment. Melatonin (0.1 microM) applied at different time points of the experiment produced an increase in the contraction, which directly correlated with a(More)
