Rhythmic Aortic Contractions Induced by Electrical Stimulation In Vivo in the Rat
For over a century, the behavior of the aorta and other large arteries has been described as passive elastic tubes in which no active contraction occurs in the smooth muscle wall. In response to pulsatile pressure changes, the vessels undergo a 'passive' elastic dilatation-contraction cycle, described as a "Windkessel" effect. However, Mangel and colleagues have presented evidence that is contr...
متن کاملEffect of protein kinase C and calcium on bradykinin-mediated contractions of rabbit vessels.
Bradykinin caused graded contractions of rings of rabbit aorta and jugular vein with EC50 values of 1.3 microM and 2.2 nM. In denuded preparations, responses of bradykinin in jugular vein but not in aorta were potentiated 1,000-fold. Both preparations bathed in calcium-free solution showed markedly depressed responses to bradykinin, but addition of 1 mM EGTA further inhibited bradykinin respons...
متن کاملSaffron Induced Relaxation in Isolated Rat Aorta via Endothelium Dependent and Independent Mechanisms
Crocus sativus L. (saffron) is a widely used food additive for its color and taste. The hypotensive effects of saffron have been shown in previous studies. The aim of this study was to evaluate the mechanism of vasodilatory effects induced by saffron on isolated rat aorta.To study the vasodilatory effects of saffron aqueous extract (0.5, 1 and 2 mg/mL), isolated rat thoracic aorta rings were co...
متن کامل[Induction of rhythmical activity in digastric muscles in an in vitro brainstem preparation from adult mice].
In this study, it was attempted to induce masticatory movements in an in vitro brainstem-spinal cord preparation isolated together with the orofacial structure from adult mice. The preparation was perfused intra-arterially with an artificial cerebrospinal fluid (ACSF) containing dextran through a cannula fixed to the descending aorta, and was placed in a bath perfused with the ACSF. Repetitive ...
