Muscarinic effects and foetal cardiovascular and hormonal responses in utero

Abstract

The results suggest that foetal automatic systems, not those hormonal factors tested, play a major role in cholinergic mechanisms mediating cardiovascular control. Furthermore, the data provide new information on how muscarinic inhibition affects renin-angiotensin system and adrenal cortex functions. Key words: aldosterone, angiotensin-converting enzyme, autonomic regulation, foetus.
