Part Descriptions
LP16194-0 Methamphetamine
Methamphetamine (MA) is a drug of abuse also referred to as meth, crystal and speed. It is a central nervous system stimulant that can be injected, smoked, snorted or ingested. Short-term MA abuse causes an increase of energy, sense of well-being and decreased appetite that lasts 6-8 hours. PMID: 19042205 MA use can lead to stroke, cardiac arrhythmia, stomach cramps, shaking, anxiety, insomnia, paranoia, hallucinations, and structural changes to the brain. Pregnant women who use MA can cause growth retardation, premature birth, and developmental disorders in neonates and long lasting intellectual deficits to the children as they grow. PMID: 10908000 Users addicted to MA experience withdrawal symptoms that include dysphoria, fatigue, insomnia and an increased appetite. In chronic MA users positron emission tomography has proven a decrease in dopamine D2 receptors which is associated with mental deterioration that can be reversed to some extent after abstaining from MA. PMID: 19042205

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.
