Part Descriptions

LP15543-9   DOPamine
Dopamine, a chemical naturally produced in the body, functions in the brain as a neurotransmitter, activating dopamine receptors. It is also a neurohormone released by the hypothalamus. As a hormone, it inhibits the release of prolactin from the anterior lobe of the pituitary. Dopamine can also be supplied as a medication to target the sympathetic nervous system, leading to increased heart rate and blood pressure. Because dopamine cannot cross the blood-brain barrier, however, when given as a drug it does not directly affect the central nervous system. To increase the amount of dopamine in the brains of patients with diseases such as Parkinson's disease and Dopa-Responsive Dystonia, a synthetic precursor to dopamine such as L-DOPA can be given, since this will cross the blood-brain barrier.

LP15543-9   DOPamine
Dopamine is a member of the catecholamine (Neurotransmitters) family in the brain, and is a precursor to epinephrine (adrenaline) and norepinephrine (noradrenaline). Dopamine is synthesized in the body (mainly by nervous tissue and adrenal glands) first by the hydration of the amino acid tyrosine to DOPA by tyrosine hydroxylase and then by the decarboxylation of DOPA by aromatic-L-amino-acid decarboxylase.

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.
