Metals in medicine are used in organic systems for diagnostic and treatment purposes. [1] Inorganic elements are also essential for organic life as cofactors in enzymes called metalloproteins . When metals are under or over-abundant in the body, equilibrium must be returned to its natural state via interventional and natural methods.
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
An experimental setup used to measure the fraction of exhaled nitric oxide (FeNO) in human breath samples. The subject blows into the tube (1) after a mouthpiece (2) has been connected to it. The wires on the side are part of the system that measures parameters like breath velocity, while the exhaled gas is taken to a FeNO analyzer (3).
The medical uses of silver include its use in wound dressings, creams, and as an antibiotic coating on medical devices. [ 2 ] [ 3 ] [ 4 ] Wound dressings containing silver sulfadiazine or silver nanomaterials may be used to treat external infections.
In lighting, translucent aluminium oxide is used in some sodium vapor lamps. [47] Aluminium oxide is also used in preparation of coating suspensions in compact fluorescent lamps. In chemistry laboratories, aluminium oxide is a medium for chromatography, available in basic (pH 9.5), acidic (pH 4.5 when in water) and neutral formulations.
The Ministry of Health has warned that nitrous oxide is a prescription medicine whose sale or possession without a prescription is an offense under the Medicines Act. [136] This would seemingly prohibit all non-medicinal uses of nitrous oxide, although it is implied that only recreational use will be targeted.
In biology and medicine, nitric oxide is however an important signalling molecule in nature and this fact is the basis of the most important applications of metal nitrosyls. The nitroprusside anion, [Fe(CN) 5 NO] 2− , a mixed nitrosyl cyano complex, has pharmaceutical applications as a slow release agent for NO.
The hydrated form is used medically to treat or prevent iron deficiency, and also for industrial applications. Known since ancient times as copperas and as green vitriol (vitriol is an archaic name for hydrated sulfate minerals ), the blue-green heptahydrate ( hydrate with 7 molecules of water) is the most common form of this material.
