What's the difference between polychroite and safranin?
Polychroite
Definition:
(n.) The coloring matter of saffron; -- formerly so called because of the change of color on treatment with certain acids; -- called also crocin, and safranin.
Example Sentences:
Safranin
Definition:
(n.) An orange-red dyestuff extracted from the saffron.
(n.) A red dyestuff extracted from the safflower, and formerly used in dyeing wool, silk, and cotton pink and scarlet; -- called also Spanish red, China lake, and carthamin.
(n.) An orange-red dyestuff prepared from certain nitro compounds of creosol, and used as a substitute for the safflower dye.
Example Sentences:
(1) Stage IV cells contain only safranin-positive granules.
(2) In 13- and 15-day embryos, mast cells showed a pale metachromasia with toluidine blue, and stained blue with Alcian Blue-Safranin O (AB-S).
(3) At 30 and 60 days, an S-100 positive band of cells separated a deep safranin-O positive hypertrophic layer from a fibrocellular surface layer.
(4) The increase of cAMP level also affected the maturation of mast cells, as the ratio of cells of mixed granulation increased, compared to the alcian blue- and safranin-present model inhibited degranulation.
(5) Astra blue (AB) safranine stained highly significantly more mast cells than did toluidine blue.
(6) There was a profound loss of safranin-O stainability in the nucleus pulposus, annulus fibrosus and cartilagenous endplate.
(7) Other staining techniques assessed were the modified Ziehl-Neelsen, safranin-methylene blue and auramine-phenol fluorescence.
(8) A zone of safranin O depletion was present in the ventral anulus fibrosus adjacent to the nucleus pulposus in all treated discs, indicating proteoglycan loss.
(9) The distribution and localization of S-100 protein was compared with safranin-O staining and H and E morphology in relatively unaffected, degenerative, and osteophytic regions of human articular cartilage from 26 joints obtained at the time of total joint replacement for osteoarthritis.
(10) Both safranin O and Giemsa were suitable nonfluorescent staining techniques; lomofungin was not.
(11) After 8-12 weeks, however, many subserosal mast cells became positive for berberine sulfate and safranin.
(12) Defects in treated joints contained Safranin O staining material that was histologically similar to a disorganized hyaline cartilage.
(13) Intestinal MC stained with the same dyes as oral MC except for 0.005% toluidine blue, berberine sulfate, and safranin.
(14) A new microspectrophotometric method was developed for quantitation of glycosaminoglycans with Safranin O dye in articular cartilage matrix.
(15) It is concluded that the use of safranine to monitor the changes in membrane potential during Ca2+ transport by mitochondria should be avoided or special care be taken.
(16) The selectivity of myoepithelial cell staining is enhanced by oxidation of sections, nuclear staining by Safranin-O, and differentiation with Tartrazine.
(17) Ferric ion-ferrocyanide staining and safranin-0-counterstaining of neocortical tissue from cats with GM1 gangliosidosis have established that pyramidal neuron meganeurites occur proximal to axonal initial segments and that they are distinct from axonal spheroids.
(18) Cytochrome oxidase reconstituted vesicles, supplemented with ascorbate and cytochrome c. induce large spectral changes of the positive dye safranine, reversed by uncouplers and inhibitors of respiration.
(19) Histologic specimens of the articular cartilage were stained with Safranin-O to assess proteoglycans-enhanced chrondrocyte function, and the synovium was stained with pentachrome.
(20) Synaptosomes were severely energy-deprived, because anaerobic glycolysis was inhibited by 90% from the aerobic level and mitochondrial membrane potential dropped below the limit that could be detected by the safranine method.
