What's the difference between macrocyte and megalocyte?
Macrocyte
Definition:
Example Sentences:
Megalocyte
Definition:
(n.) A large, flattened corpuscle, twice the diameter of the ordinary red corpuscle, found in considerable numbers in the blood in profound anaemia.
Example Sentences:
(1) Finally, morphological analysis revealed a progressive increase of RBC with Heinz bodies, of macro-megalocytes and of immature erythroblasts thus indicating that the cell population, produced during recovery from PHZ induced anemia, is widely heterogeneous.
(2) Megalocytes with huge nuclei and nucleoli frequently occur.
(3) The RNA polymerase activity of the megalocyte nuclei was essentially comparable to the activity observed in normal liver cells.
(4) However, the simplest explanation of our results would be to consider that the potential tumour cells are located among the megalocytic cells, without admitting that every megalocyte is obligatorily a precancerous cell.
(5) However, the increased uptake of 3H-thymidine by megalocytes, in the absence of observable mitotic activity, suggests that these cells are in the process of hypertrophy.
(6) The first case of favorable evolution under conservative treatment for acute renal failure caused by megalocytic interstitial nephritis and the ongoing transitory impairment of the polymorphonuclear bactericidal ability are described.
(7) The typical oval cells and the megalocytic hepatocytes were not fluorescent.
(8) It is concluded that the megalocytes are functionally normal cells, except that they are in the process of cellular hypertrophy and are incapable of division due to potent antimitotic action of the pyrrolizidine alkaloids.
(9) Megalocytes also appeared when rats were partially hepatectomized as late as 26 weeks after injection of the carcinogen.
(10) No patient was free from side effects, which included gingival hypertrophy (90% of patients), increased alkaline phosphatase activity (55%), suggestion of a sensory peripheral neuropathy (34%), central nervous system (CNS) intoxication (22%), coarsened facial features (19%), tendency to bleed excessively (15%), hirsutism (12%), and mild megalocytic anemia (5%).
(11) These are the first macroscopically visible tissues to appear in organ culture and they give rise to megalocytes, the ultimate stage of blood cell evolution in the normal mouse embryo yolk-sac.
(12) The radiologic and ultrasonic findings are presented in a case of megalocytic interstitial nephritis, a very rare condition, in many ways similar to renal malacoplakia.
(13) On the basis of other studies, megalocytic hepatosis and foci of cellular alteration are both considered to be important precursor lesions in the stepwise histogenesis of hepatic neoplasms.
(14) The groups of small hyperplastic cells showed normal or increased activity and there was increased enzyme activity in the megalocytes.
(15) Although at 7 days after the hepatectomy many megalocytes could still be found in centrilobular zones, the majority of the hepatocytes were of normal size or smaller.
(16) Protease activity extracted from membranes of megalocytes was not different from normal.
(17) In addition, megalocytic change of hepatic cells with intranuclear inclusions, pelliosis hepatis, and cholangiomatous lesions were also encountered frequently in the livers.
(18) Two cases--although with similar cellular infiltrate--had a marked paucity of Michaelis-Gutmann bodies and thus might have been classified as megalocytic interstitial nephritis were it not for the identification of such calcific intracellular inclusions under the electron microscope.
(19) It is suggested that the tubular granulated cells of megalocytic interstitial nephritis regarded as identical with renal cortical malakoplakia also have a tubular epithelial origin.
(20) At 48 hr after partial hepatectomy, following completion of the first mitoses, almost all hepatocytes were enlarged (megalocytes) and many contained enlarged nuclei.
