Molar Solution: From 1 Different Sources
a solution in which the number of grams of dissolved substance per litre equals its molecular weight, i.e. a solution of molarity 1 M.
mole1 n. the *SI unit of amount of substance, equal to the amount of substance that contains as many elementary units as there are atoms in 0.012 kilograms of carbon-12. The elementary units, which must be specified, may be atoms, molecules, ions, electrons, etc., or a specified group of such entities. One mole of a compound has a mass equal to its molecular weight expressed in grams. Symbol: mol.
mole2 n. a nonmalignant collection of pigmented cells in the skin. Moles are rare in infancy, increase in numbers during childhood and especially in adolescence, but decline in numbers in old age. They vary widely in appearance, being flat or raised, smooth or hairy. Changes in the shape, colour, etc., of moles in adult life should be investigated as this may be an early sign of malignant *melanoma. Medical name: pigmented naevus. See also atypical mole syndrome.
A solution commonly used as a means of ?uid replacement in dehydrated patients (see also DEHYDRATION). Each litre contains 3·1 grams of sodium lactate, 6 grams of sodium chloride, 0·4 grams of potassium chloride, and 0·7 grams of calcium chloride.... hartmann’s solution
A compound solution of iodine and potassium iodide used in the preoperative preparation of patients with thyrotoxicosis (see THYROID GLAND, DISEASES OF). The solution is taken orally.... lugol’s solution
The last three TEETH on each side of the JAW.... molar teeth
A liquid preparation containing one or more soluble drugs, usually dissolved in water.... solution
(BSS) a solution containing physiological concentrations of sodium chloride, potassium chloride, calcium chloride, magnesium chloride, sodium acetate, and sodium citrate. Such fluids are isotonic to eye tissue; they are used during intraocular surgery and to replace intraocular fluids.... balanced salt solution
a *physiological solution used for infusion into the circulation. In addition to essential ions, it also contains glucose. [A. F. Hartmann (1898–1964), US paediatrician]... hartmann’s solution
(aqueous iodine oral solution) a solution of 5% iodine and 10% potassium iodide, used in the treatment of thyrotoxicosis in emergencies, such as *thyroid crisis, or when surgery cannot wait for more conventional treatments. For its mode of action it utilizes the abnormal *Wolff–Chaikoff effect, seen in cases of thyroiditis. [J. G. A. Lugol (1786–1851), French physician]... lugol’s solution
a defect involving a deficiency in the mineralization of permanent first molar and incisor teeth during their maturation phase, thought to be due to a disturbance of development around the time of birth. It often presents in discolouration (yellow, brown, cream, or white depending on severity) and results in the affected teeth being more susceptible to decay.... molar–incisor hypomineralization
one of a group of solutions used to maintain tissues in a viable state. These solutions contain specific concentrations of substances that are vital for normal tissue function (e.g. sodium, potassium, calcium, chloride, magnesium, bicarbonate, and phosphate ions, glucose, and oxygen). An example of such a solution is *Ringer’s solution.... physiological solution
(Ringer’s mixture) a clear colourless *physiological solution of sodium chloride (common salt), potassium chloride, and calcium chloride prepared with recently boiled pure water. The osmotic pressure of the solution is the same as that of blood serum. Ringer’s solution is used for maintaining organs or tissues alive outside the animal or human body for limited periods. Sterile Ringer’s solution may be injected intravenously to treat dehydration. [S. Ringer (1835–1910), British physiologist]... ringer’s solution
an electrolyte solution used to prevent dehydration in patients who have a large watery output of faecal fluid from their *stoma, often due to *short bowel syndrome. Originally formulated in St Mark’s hospital in London, the solution consists of 1l water, six heaped 5-ml teaspoons glucose, one level 5-ml teaspoon salt, and half a heaped 2.5-ml teaspoon sodium bicarbonate.... st mark’s solution
