What's the difference between albinism and pigment?

Albinism


Definition:

  • (n.) The state or condition of being an albino: abinoism; leucopathy.

  • (16) Ocular albinism is distinguished from the more common oculocutaneous albinism by the presence of normal pigmentation of skin and hair in the former condition.
  • (17) The iris shows the lack of pigmentation in various types of albinism.
  • (18) It has recently been suggested that aberrant misrouting of retino-geniculate-cortical (RGC) projections, a finding previously noted only in albinism, may be an additional feature of the Prader-Willi syndrome.
  • (19) Histopathologic and ultrastructural findings in an eye from a patient with complete oculocutaneous albinism are reported.
  • (20) This is believed to be the first case of albinism reported in sheep.

Pigment


Definition:

  • (n.) Any material from which a dye, a paint, or the like, may be prepared; particularly, the refined and purified coloring matter ready for mixing with an appropriate vehicle.
  • (n.) Any one of the colored substances found in animal and vegetable tissues and fluids, as bilirubin, urobilin, chlorophyll, etc.
  • (n.) Wine flavored with species and honey.

Example Sentences:

  • (1) The results also suggest that the dispersed condition of pigment in the melanophores represents the "resting state" of the melanophores when they are under no stimulation.
  • (2) Differences between the albino vs pigmented strains were observed following injections of saline.
  • (3) Two lectins, wheat germ agglutinin (WGA) and peanut agglutinin (PNA), were used to compare domains within the interphotoreceptor matrices (IPM) of the cat and monkey, two species where the morphological relationship between the retinal pigment epithelium (RPE) and photoreceptors is distinctly different.
  • (4) Uptake studies with 22Na were performed in cultured bovine pigmented ciliary epithelial cells, in order to characterize mechanisms of Na+ transport.

  • (7) Changes in protein phosphorylation induced by phagocytic challenge were identified in cultured rat retinal pigment epithelium (RPE) following exposure to isolated rat rod outer segments (ROS) or to polystyrene latex microspheres (PSL).
  • (8) Both categories frequently showed pellagrous pigmentation and mucocutaneous signs of B-vitamin deficiency.
  • (9) We show that, in digitonin-permeabilized goldfish xanthophores, the pigment organelles can be induced to disperse by a combination of cAMP, ATP, and xanthophore cytosol.
  • (10) A red pigment produced by the actinomycete strain B 4358 was identified as butyl-meta-cycloheptylprodiginine (4) by 1H, 13C and correlation via long range coupling NMR spectra.
  • (11) Two unusual types of oral mucosal pigmentation are reported.
  • (12) These results are consistent with the idea that RPE pigment dispersion is triggered by a substance that diffuses from the retina at light onset.
