LP15271-7 Norepinephrine
Norepinephrine (INN) or noradrenaline (BAN) is a catecholamine and a phenethylamine with chemical formula C 8 H 11 N O 3. The natural stereoisomer is L-(ˆ')-(R)-norepinephrine. It is released from the medulla of the adrenal glands as a hormone into the blood, but it is also a neurotransmitter in the nervous system where it is released from noradrenergic neurons during synaptic transmission. As a stress hormone , it affects parts of the human brain where attention and impulsivity are controlled. Along with epinephrine, this compound affects the fight-or-flight response, activating the sympathetic nervous system to directly increase heart rate, release energy from fat, and increase muscle readiness. Norepinephrine is released when a host of physiological changes activated by a stressful event, unleashed in part by activation of an area of the brain stem called the locus ceruleus. This nucleus is the origin of most norepinephrine pathways in the brain.

LP15271-7 Norepinephrine
Norepinephrine, a precursor of epinephrine secreted by the adrenal medulla, is a widespread central and autonomic neurotransmitter. It is the principal transmitter of most postganglionic sympathetic fibers and of the diffuse projection system in the brain arising from the locus ceruleus. It is also found in plants and is used pharmacologically as a sympathomimetic.

LP32035-5 Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
