J. Neurochem. (2006) 97, 310–333. Norepinephrine (NE) is the principle chemical messenger employed in central noradrenergic and peripheral sympa-thetic synapses. The norepinephrine transporter (NET), present on the plasma membrane of noradrenergic neurons, limits the action of NE through reuptake into the cytoplasm.

Here, we report that, compared to indole, epinephrine and norepinephrine exert divergent effects on EHEC chemotaxis, motility, biofilm formation, gene expression, and colonization of HeLa cells. Using a novel two-fluorophore chemotaxis assay, it was found that EHEC is attracted to epineph-rine and norepinephrine while it is repelled by indole.

This was an un-expected finding because, as has been already indicated, in cat's isolated lungs epinephrine has well marked pulmonary vasoinotor effects. The dose of epinephrine given was approxi-mately 7 to 14 times that found by Polkow & von Euler12 in the adrenal venous blood of cats under chloralose anesthesia.

After adjustment, the difference in rearrest rates between epinephrine and. norepinephrine persisted (OR 3.28, 95% CI 2.25-5.08), and the odds of pulses at hospital arrival. were lower in the epinephrine group (OR 0.52 95% CI 0.32-0.83).

Hyperglycemia is a metabolic derangement that fre-quently develops after cardiovascular surgery. The periop-erative administration of inotropic and vasoactive agents, such as epinephrine and norepinephrine, are common in the management of cardiac surgery patients and are known to contribute to the development of postoperative hypergly-cemia.

Methylation of norepinephrine by S-adenosylmethionine gives epinephrine.

Epinephrine salts are formed when you dissolve pure "epinephrine base" in acid. Epinephrine base is only sparingly soluble in water, while the salts dissolve readily. When used in drug applications, epinephrine is usually administered in the salt form, as a dilute water solution. Therefore, as a rough rule of thumb, if

not with infusions (available evidence indicates that a phenylephrine infusion functions pr etty similarly compared to a norepinephrine infusion). It is safe to give peripherally. Phenylephrine is about ten times less potent than nor epinephrine (i.e. 10 mcg/min phenylephrine is r oughly equivalent to 1 mcg/min norepinephrine).

Dopamine neurons are located in the midbrain substantia nigra and ventral tegmental area. These neurons project densely to the dorsal and ventral striatum, respectively. Figure 1. Dopamine is synthesized in two steps from the amino acid tyrosine in dopaminergic neurons. Norepinephrine is produced from dopamine in noradrenergic neurons.

Norepinephrine equivalence (NEE) is a scale to quan-tify vasopressor exposure, which converts the dose of each vasopressor equivalent to that of norepinephrine. NEE has been used in clinical trials to set an inclusion criterion, define trial protocols, report baseline char-acteristics, and assess outcomes [13–19].
