Cholinergic signal activated renin angiotensin system associated with cardiovascular changes in the ovine fetus.
AIM Cholinergic regulation is important in the control of cardiovascular and endocrine responses. The mechanisms behind cardiovascular responses induced by cholinergic activation are explored by studying hormonal systems, including renin-angiotensin and vasopressin (VP). RESULTS In chronically prepared fetal sheep, intravenous infusion of the cholinergic agonist carbachol increased fetal syst...
متن کاملAngiotensin-(1--7) in the ovine fetus.
In the adult animal, ANG-(1-7) may counterbalance some effects of ANG II. Its effects in the fetus are unknown. Basal ANG-(1-7), ANG I, ANG II, and renin concentrations were measured in plasma from ovine fetuses and their mothers (n = 10) at 111 days of gestation. In the fetus, concentrations of ANG I, ANG-(1-7), and ANG II were 86 +/- 21, 13 +/- 2, and 14 +/- 2 fmol/ml, respectively. In the ew...
متن کاملRenin-angiotensin system and unilateral ureteral obstruction
Unilateral ureteral obstruction (UUO) is a clinical scenario that leads to obstructive nephropathy. UUO alters the expression of many mediators in the ipsilateral kidney. Renin-angiotensin system (RAS) is involved in UUO. Angiotensin II (Ang II) and angiotensin 1-7 (Ang 1-7) as the main arms of RAS influence kidney function which may alter by UUO. Ang II via Ang II receptor subtypes I (AT1R) ...
متن کاملRenin angiotensin system and gender differences in the cardiovascular system.
In the effort to explain gender-related differences of the cardiovascular system, the renin-angiotensin system experienced intensive exploration. Indeed, the development of hypertension as well as the progression of coronary artery disease and heart failure have two factors in common: (1) display distinct gender specific characteristics and (2) are enhanced by the renin-angiotensin system. It i...
متن کاملCardiovascular Risk Reduction with Renin-Angiotensin Aldosterone System Blockade
This paper examines the evidence supporting treatments within the renin-angiotensin aldosterone system (RAS), the role cardioprotection plays within the management of hypertension, considerations around medication adherence, and the role of the nurse or nurse practitioner in guiding patients to achieve higher hypertension control rates. A large body of data now exists to support the use of angi...
