Altered β1-3-adrenoceptor influence on α2-adrenoceptor-mediated control of catecholamine release and vascular tension in hypertensive rats β2AR activity was a required substrate for α2AR auto inhibition of norepinephrine release in WKY. β1+2AR opposed α2AR inhibition of norepinephrine release in SHR and epinephrine secretion in both strains. βAR-α2AR reciprocal control of vascular tension was absent in SHR.

Reason for the aggravation of diseases caused by inflammation and the ineffectiveness of NSAIDs on these diseases in rainy weather  Indomethacin, diclofenac, meloxicam and nimesulide were found to exert anti-inflammatory effects by decreasing adrenaline levels but not affecting corticosterone levels. The anti-inflammatory effects of the tested drugs was eliminated on rainy days due to the low level of corticosterone. Catecholamines were measured in serum/plasma with Chromsystems HPLC assay. 2009
Effects of meal timing on changes in circulating epinephrine, norepinephrine, and acylated ghrelin concentrations: a pilot study In conclusion, E/NE concentrations were higher after the morning meal, while AG showed an opposite behavior.
