lytic1889

1889 New Sydenham Soc. Lexicon Lytic, of, or belonging to, a loosing or dissolving.

1907 Practitioner Apr. 500 It boots little whether that increase in heat [during fever] is due to an excessive production, as the ‘genetic’ protagonists proclaim, or an inadequate dissipation, as their ‘lytic’ opponents contend.

1962 Lancet 26 May 1123/2 Ice placed inside the oxygen tent and cold sponging are remarkably efficient in lowering the temperature of these infants to 86–88°F (31°C)... In our experience ‘lytic’ agents are not required.

2. Bacteriology. Pertaining to or causing lysis (sense 3); lytic cycle, the sequence of events that takes place from the infection of a bacterium by a virulent phage to lysis of the bacterium and the release of progeny phage.

1902 Jrnl. Exper. Med. 17 Mar. 281 Only when the lytic serum is very fresh will solution be effected.

1925 C. H. Browning Bacteriol. ix. 214 He concluded that the agent causing this solution or lytic action was a living virus.

1968 R. Rieger et al. Gloss. Genetics & Cytogenetics 34 The introduction by infection of the genetic material of virulent phages into a susceptible host results invariably in the death and dissolution of the cell with the release of (100–10000) new phages (‘lytic cycle’).

1972 Nature 24 Mar. 144/3 It is much more likely that the tails kill sensitive cells either by injecting lytic enzymes or by acting at the cell surface.

lytic cocktail n. Pharmacology (now chiefly historical) a combination of drugs (typically the sedative chlorpromazine, the opioid pethidine, and the antihistamine promethazine) used originally as an adjunct in general anaesthesia and later mainly for sedation and for the management of conditions such as eclamptic seizures and chronic pain. [After French cocktail lytique (H. Laborit & P. Huguenard 1951, in Presse médicale 13 Oct. 1329/1).]

1952 Internat. Abstr. Surg. 94 196/2 The designation ‘lytic cocktail’ has been proposed for the method.

1988 Hastings Center Rep. 18 22/2 In the case of terminally ill cancer patients, it is not uncommon in our country [sc. Uruguay] for the physician ultimately to resort to a ‘lytic cocktail’ comprised of an opiate, a sedative, and an analgesic administered in a constant intravenous drip.

2002 Internat. Jrnl. Gynecol. & Obstetr. 76 7/1 They [sc. data] do confirm magnesium sulfate as the drug of choice for women with eclampsia, and are sufficient to suggest that lytic cocktail be withdrawn from clinical practice.
