Possible Interaction: Catechin and Norepinephrine

“There was … patients receiving norepinephrine (odds ratios = 15, p = 0.… = 12, p = 0.001) and C (odds ratios = 17, p = 0.001).ConclusionIn critically ill patients on intermittent hemodialysis, the absence of hypervolemia … ultrasound predisposes to intradialytic hypotension and suggests alternative techniques of hemodialysis to provide better hemodynamic stability.”

“The alpha(2)-adrenergic receptor (alpha(2)AR) subtypes A and C are both expressed on presynaptic nerves and act to inhibit norepinephrine release via negative feedback.”

“Although cool exposure had no significant effects on plasma triglyceride, free fatty acid, and glycerol levels, changes in adrenaline and noradrenaline levels at C were significantly lower than WH during the prolonged exercise (p<0.01).”

“Standing (S), isometric hand exercise (… in cold water C ) resulted in … plasma NE concentrations in normal subjects; plasma E concentrations rose only at 6 minutes of S. Average rises (percentage +/- SEM) … +/- 3 (S), 22 +/- 6.5 (H), and 46 +/- 4.1 (C); for E, 33.1 +/- 12.2 (S).”

“There was a significantly lower percentage response of plasma NE concentrations in patients during S (P less than 0.001) and C (P less than 0.01), compared with that in normal subjects.”

“BACKGROUND Although norepinephrine induces cardiac hypertrophy by activating protein kinase A and C through beta- and alpha 1-adrenoceptors, respectively, protein kinase A has been reported to inhibit cell growth in many other cell types.”

“ Norepinephrine rose from 145 +/- 10 to 242 +/- 32 pg/ml by 150 min of exercise in C and from 150 +/- 25 to 333 +/- 83 pg/ml in DN.”
