Dict. Suppl.); (b) = peptotoxin. ˈtoxophil |-fɪl| a. [Gr. -ϕιλος loving], having affinity for a toxin. ˈtoxophore |-fɔə(r)| [ad. G. toxophor adj. (P. Ehrlich 1898, in Deutsch. med. Wochenschr. 22 Sept. 599/2)], toxophoric |-ˈfɒrɪk|, toxophorous |-ˈɒfərəs| adjs. [Gr. -ϕορος bearing, carrying], poison-bearing; applied to a particular group of atoms in the molecule of a toxin to which its toxic properties are due; also toxophore n., a toxophoric group. toxophylaxin |-fɪˈlæksɪn| [Gr. ϕύλαξ guard, protector], toxosozin |-ˈsəʊzɪn| [Gr. σώζειν to save], names for defensive proteins or antitoxins (see quots.). toxoprotein |-ˈprəʊtiːɪn|, a toxic protein, or mixture of a toxin and a protein.
1907Med. Record 17 Aug. 279 The original cause of the lack of coagulation may be *toxoinfectious, or due to marked congestion.
1896Allbutt's Syst. Med. I. 526 Scholl, growing the vibrio, in eggs, obtained a *toxo-peptone.
1902Vaughan & Novy Cellular Toxins (ed. 4) 182 The body cells must possess *toxophil side chains. By this we mean that.. there are groups of atoms which may combine with bacterial toxins.
1899*Toxophore [see haptophore]. 1900Lancet 18 Aug. 528/1 The toxophore group of the toxin molecule being much less stable than the haptophore group was much more easily destroyed. 1903Brit. Med. Jrnl. 21 Mar. 654 The other atomic group is toxophore, namely, is the cause of the specific toxic action. 1951Kirk & Othmer Encycl. Chem. Technol. VII. 121 In World War I, derivatives of trivalent arsenic received considerable attention, the structure {b1}As{b2} being considered a toxophore.
1902Brit. Med. Jrnl. 29 Mar. 785 The toxin molecule..must possess a second group which he [Ehrlich] calls the *toxophoric group. 1904Ibid. 10 Sept. 574 Although the toxophoric group may be similar, the haptophor is dissimilar.
1902Encycl. Brit. XXVI. 65/1 In the molecule of toxin there are at least two chief atom groups—one, the ‘haptophorous’, by which the toxin molecule is attached to the cell protoplasm; and the other the ‘*toxophorous’, which has a ferment-like action on the living molecule, producing a disturbance which results in the toxic symptoms.
1899Syd. Soc. Lex., *Toxophylaxin, a defensive proteid produced in the body of an animal which has acquired immunity for a given infectious disease, and which has the power of rendering inert the toxic products of the pathogenic micro-organisms to which the condition was due.
1896Allbutt's Syst. Med. I. 523 The *toxo-proteins in reality are mixtures of albuminous, proteid, or albuminoid bodies with the true toxins.
1899Syd. Soc. Lex., *Toxosozin, a defensive proteid found in the body of a normal animal which has the power of protecting itself to a greater or less degree against micro-organisms and their products. |
