Cardiohemodynamics and efficiency Frank-Starling mechanism in spontaneously hypertensive rats

Abstract: Кардіогемодинаміка та ефективність механізму Франка-Старлінга у щурів зі спонтанною гіпертензією У дослідженні на щурах з генетично детермінованою артеріальною гіпертензією і щурах контрольної групи лінії Вістар вивчали особливості кардіогемодинаміки і механізму Франка-Старлінга. Щурів наркотизували за допомогою уретану (1,25 г/кг, внутрішньоочеревинно). Зміни тиску і об'єму лівого шлуночка з візуалізацією кривих залежності цих величин протягом серцевого циклу реєстрували за допомогою ультрамініатюрного катете… Show more

“…Later, NOguanylate cyclase-protein kinase G (NO-GC-PKG) pathway was considered as the main regulator of intracellular calcium metabolism in the Frank-Starling mechanism (BELGE et al, 2005;Casadei and Sears, 2003;Scotcher et al, 2016). Reduced NO production might be the main reason of deteriorated pressure-volume (P-V) regulation in arterial hypertension, Parkinson's disease or other pathological conditions, which also indicates the involvement of the NO system in the heterometric regulation of the heart function (Dorofeieva et al, 2012;Talanov et al, 2009). At the same time, stimulation of NO synthesis by catestatin protein increase Frank-Starling response not only in hypertensive but also in normotensive rat heart (Angelone et al, 2015).…”
