Through an intravenous line attached to one arm, he was receiving pressors, drugs that cause the heart to pump more effectively and increase the tone of the vessels to help maintain blood pressure.
Combination of vascular endothelial growth factor with bosentan failed to increase the tone (n = 4).
The Fisher scores for tone discrimination for the different vowels using the various methods are given in Tables 1 to 4. For comparison, the Fisher scores for vowel discrimination are given inTables 9 to 12.The experimental results show that FrFT analysis increases the tone discriminability for most of the order selection methods proposed here.
Opioids decrease the tone of gastric smooth muscles and increase the tone of sphincters.
They may, therefore, increase the tone of vessels – perhaps beyond normal levels – and thus alter the blood flow response evoked by neuronal activity (see above).
The drawback is that this drug also increases the tone of the gastric sphincter, so although the esophagus may work harder, it is effectively pushing against the closed door of the gastric sphincter, so you are back to square one.
However an increased level of EPS (2%) used in the present study was increasing the inflammatory tone upon ingestion.
All dynamic preload indicators (SVV, SPV, PPV and PPVapnea) were significantly reduced by phenylephrine during hemorrhage, mainly by increasing the vasomotor tone.
The underfilling is sensed by the arterial baroreceptors, which activate primarily the sympathetic nervous system and renin-angiotensin-aldosterone system, as well as vasopressin, to restore the arterial filling by increasing the vascular tone and retaining sodium and water.
In this regard, lactotrope proliferation would be suppressed both by a direct action on the pituitary by increasing the dopaminergic tone and also by an indirect effect by reducing the progesterone-induced tumorigenic signaling pathways (27).
