In vitro effect of M1-cholinoreceptor blockade on the cardiac inotropic function was examined in rats aging 1, 3, 6, 8, and 20 weeks. In 1- and 3-week old rat pups, the sympathetic control of the heart has not developed, ...

© 2020, Springer Science+Business Media, LLC, part of Springer Nature. The study examined the effects of α1A-adrenoceptor stimulation on chronotropic function of Langendorff-perfused isolated heart ex vivo and on cardiac ...

© 2015, Springer Science+Business Media New York. Selective blockade of various α2-adrenoceptors exerts various effects on the cardiovascular system in rats. Blockade of α2A/D-adrenoceptors in experimental animals decelerates ...

We have studied the formation of interrelation between sympathetic and parasympathetic influenceson the heart in dogs and rats in ontogenesis during electrical stimulation of nerves. To achieve the tasks set we have carried ...

Studies by EPR spectroscopy showed that 30-day exposure of rats to augmenting hypokinesia led to a 3-fold increase in nitric oxide (NO) production in the heart and 2-fold in the liver. These results indicated that long-term ...

The study examined the effect of α1-adrenoceptor stimulation with methoxamine on chronotropic function of isolated heart perfused ex vivo according to Langendorff and cardiac chronotropy in vivo. Stimulation of α1-adrenoceptors ...

© 2015, Springer Science+Business Media New York. We studied the effects of selective blockade of various subtypes of α2-adrenoceptors on cardiac chronotropy in newborn rats. This period in rats is characterized by the ...

Paramagnetic complexes containing nitric oxide (NO) have been assayed in rat heart and liver tissues by EPR spectroscopy to investigate the time variation of NO production during postnatal development. Nitric oxide levels ...
