What's the difference between corpuscle and poikilocyte?

Corpuscle


Definition:

  • (n.) A minute particle; an atom; a molecule.
  • (n.) A protoplasmic animal cell; esp., such as float free, like blood, lymph, and pus corpuscles; or such as are imbedded in an intercellular matrix, like connective tissue and cartilage corpuscles. See Blood.

  • (18) The major derivative possesses a paracrystalline corpuscle and the minor has an electron-dense area in the juxta-axonemal region.
  • (19) The shape of this age-related decline in the ratio corresponded well with the decrease in the number of Meissner corpuscles found in histological studies.

Poikilocyte


Definition:

  • (n.) An irregular form of corpuscle found in the blood in cases of profound anaemia, probably a degenerated red blood corpuscle.

Example Sentences:

  • (1) In both studies, the poikilocytes were identified as echinocytes, spiculated erythrocytes, and schizocytes.
  • (2) Spiculated poikilocytes occur in several different forms.
  • (3) Light microscopic studies indicated that approximately one-fifth as much urea is required to block sickling as is necessary to reverse sickled poikilocytes to normal forms.
  • (4) Calves less than six weeks of age had more poikilocytes, lower serum iron, higher total iron binding capacity, less adult hemoglobin and more neonatal and fetal hemoglobin than calves greater than six weeks of age.
  • (5) Bite cells are morphologically characterized as poikilocytes with one or more semicircular portions removed from the cell margin.
  • (6) Sensibilization has resulted in the rise of echinocyte, poikilocyte and schizocyte blood level.
  • (7) A kindred is described in which two brothers with a poikilocytic variant of hereditary elliptocytosis (HE) were found to have a defect of spectrin dimer association and a decreased spectrin-band 3 ratio.
  • (8) Clinical expression of HE in these families ranges from mild elliptocytosis without hemolysis to severe poikilocytic hemolytic anemia clinically resembling HPP.
  • (9) Thus, co-inheritance of two alpha spectrin defects can result in a poikilocytic hemolytic anemia milder than that usually found in HPP.
  • (10) We propose that the patients' red-cell morphology is the result of in vivo fragmentation, and that the spleen is the major site of microspherocyte and poikilocyte destruction.

  • (14) Occasional nonspecific poikilocytes are found in most normal blood smears, but dominance of one or more forms of poikilocytes usually is indicative of a specific anemia or disease in an organ or organ system.
  • (15) The action of constant current (0.01-3 A, 1-25 V) on human blood during varying exposures induced intensified plaque-formation in the preparations of the local hemolysis test, and transformation of red blood cells-discocytes into echino- and poikilocytes that was attended by pronounced changes in the extent, intensity of light diffusion, natural green and red luminescence of red blood cells caused by flavoproteins and metalloporphyrins.
