Catecholamines, frequently used in sepsis therapy of critically ill patients, have been shown to inhibit endotoxin-induced expression of monocyte cytokines, such as TNF-α or IL-6 [ 1 ]. The aim of our study was to prove whether epinephrine (EPI) and norepinephrine (NOREPI) may also affect...
York Fasted sheep (20-30 kg) were anesthetized with thiopental sodium (20 mg/kg iv) and intubated. The endotracheal tube was connected to a Harvard respirator, and the animals were ventilated with a mixture of oxygen lung lymph flow; lymph-to-plasma prot
CONCLUSIONS: Administration of the vasopressors phenylephrine, epinephrine, and norepinephrine failed to increase microcirculatory blood flow in most abdominal organs despite increased perfusion pressure and-in the case of epinephrine and norepinephrine-increased systemic blood flow. In fact, norepinephrine and...

The effect of 24-h pretreatment with epinephrine (EPI) or norepinephrine (NE) on alpha(2)- and beta-adrenoceptor agonist-induced, cAMP responses and G(i3)alpha-protein expression was studied in primary cultures of rat superior cervical ganglionic (SCG) neurons. SCG neurons, 10 to 12 days in...
Some beta blockers, for example, pindolol (Visken) have intrinsic sympathomimetic activity (ISA), which means they mimic the effects of epinephrine and norepinephrine and can cause an increase in blood pressure and heart rate. Beta blockers with ISA have smaller effects on heart rate than agent...
