ˌhypersensitiˈzation
[f. next + -ation.]
The action or process of hypersensitizing, or the state of being hypersensitized. a. Med. b. Photogr.
a.1908Jrnl. Amer. Med. Assoc. 15 Feb. 528/1 The remarkable phenomenon of hypersensitization or anaphylaxis. 1947L. Schwartz et al. Occup. Dis. Skin (ed. 2) iv. 39 If such a worker is able to keep on working, the dermatitis clears up... In other words exposure first causes a hypersensitization, then further exposure causes a dermatitis, and still further exposure causes hyposensitization. 1959New England Jrnl. Med. CCLX. 170/2 The use of human gamma globulin rather than that derived from animal plasma significantly diminishes the risk of hypersensitization to a foreign protein.
b.1933Carroll & Hubbard in Bureau of Standards Jrnl. Res. X. 212 We shall use the term ‘hypersensitization’ to cover any case in which increase in sensitization by a dye is produced by treatment with a material itself colorless or absorbing a spectral region different from that of the dye. Ibid. 213 In our experiments hypersensitization always involved an increase in relative sensitivity to the longer wave lengths. 1956Electronic Engin. Feb. 78/1 The processes of hyper-sensitization (treatment before exposure) and latensification (treatment after exposure) may give an increase in relative speed of up to two or three times with normal development. 1964J. Roubier Odham's Pract. Photogr. & Film-Making ii. 34 The effective speed of an emulsion can be raised by 100% or even 150% by hypersensitisation. |
