1897R. C. Cabot Guide Clin. Exam. Blood 77 The typical megaloblast is an abnormally large cell.., frequently showing marks of degeneration (polychromatophilia) in its protoplasm, which is therefore brownish or purplish with the Ehrlich-Biondi stain. Ibid. 124 More common than in any other form of anæmia are the polychromatophilic red corpuscles (see Plate IV.). 1898A. C. Coles Blood Pl. I (caption) Polychromatophile corpuscles. 1908Practitioner Aug. 324 In polychromatophil degeneration, the stained cell may vary in colour from lilac to quite deep blue (when Jenner's stain has been used). 1933A. Piney tr. Morawitz's Blood Dis. in Clin. Pract. ii. 12 Among the non-nucleated red corpuscles Jenner's stain often shows elements which are not purely red, but violet: this is polychromatophilia... More rarely erythrocytes with blue stippling are found: these have the same significance as the polychromasic ones. 1947Jrnl. Lab. & Clin. Med. XXXII. 765 The polychromatophile normoblasts likewise were identified by their nuclei..and not by the cytoplasm which was basophilic rather than polychromatophilic. 1956E. Ponder tr. Bessis's Cytol. Blood ix. 246 In the normal state, the circulating blood contains an extremely small number of polychromatophil red cells... In pathological conditions..polychromatophil red cells can appear in the blood in large numbers and their basophil material can take the form of little structures. 1973B. A. Brown Hematol. ii. 34/2 Polychromatophilia..indicates red blood cells containing RNA. They will stain a pinkish-gray to pinkish-blue color. 1974Exper. Parasitol. XXXVI. 6 Early in the course of the developing anemia, many polychromatophilic erythrocytes and occasional normoblasts were found in the blood. |
