Age-related peculiarities of the effect of α-adrenoceptor blockade on cardiac function in rats

Ziyatdinova N.; Zefirov A.; Zefirov T. (2002)

Blockade of α1-adrenoreceptors with prazosin produces bradycardia. The degree of this bradycardia in rats depends on age. In adult (20-week-old) rats bradycardia is pronounced, in 3-week-old rats it is insignificant, and ...
Blockade of hyperpolarization-activated channels modifies the effect of β-adrenoceptor stimulation

Zefirov T.; Ziyatdinova N.; Gainullin A.; Zefirov A. (2002)

Experiments on rats showed that blockade of hyperpolarization-activated currents moderates tachycardia induced by β-adrenoceptor agonist isoproterenol and potentiates the increase in stroke volume produced by this agonist. ...
Parasympathetic nervous system modulates effects of hyperpolarization-activated channel blockade

Ziyatdinova N.; Zefirov T. (2002)

Bilateral vagotomy eliminating extracardiac parasympathetic influences on the heart modulates the changes in variational pulsogram during blockade of hyperpolarization-activated currents, but has no significant effect on ...
