1939 A. T. Shohl Mineral Metabolism i. 11 Following are definitions of other terms used in this book:..osmol, or osM = the amount of electrolyte equivalent in osmotic pressure to that of a molar or molal solution of non-ionized solute.
1956 A. C. Guyton Textbk. Med. Physiol. xxvi. 302/2 If each molecule ionizes into two ions each of which is osmotically active, then 1 mol of solute equals 2 osmols.
1964 L. C. Martin Clin. Endocrinol. (ed. 4) i. 51 In normal subjects they found that the initial serum osmolality was 285 ± 4·4 m-osmoles/kg. of water.
1977 Ann. Internal Med. 86 554/1 This accumulation of idiogenic osmols causes an intrabrain cell hyperosmolality, with an influx of water into the cells.
1984 J. F. Lamb et al. Essent. Physiol. (ed. 2) App. 441 The osmotic strength of a solution may be expressed as osmoles per litre of volume (osmolarity) or osmoles per litre of water (osmolality).
2003 Amer. Jrnl. Physiol. 284 f65 Anaerobic glycolysis..is also a source of net osmoles, because it splits each glucose into two lactate molecules.
