What is a swollen cell called?
Cellular swelling (synonyms: hydropic change, vacuolar degeneration, cellular edema) is an acute reversible change resulting as a response to nonlethal injuries. It is an intracytoplasmic accumulation of water due to incapacity of the cells to maintain the ionic and fluid homeostasis.
What does Myocytolysis mean?
Myofibrillar degeneration (myocytolysis) is a distinctive sublethal injury of cardiac muscle cells. Affected fibers have pale eosinophilic sarcoplasm and lack cross-striations. Ultrastructurally, myofibrils have variable extent of dissolution (myofibrillar lysis).
What does Hydropic change mean?
Hydropic change is one of the early signs of cellular degeneration in response to injury. Hydropic change refers to the accumulation of water in the cell. This is clearly seen in this slide. Note the large clear cells occupying 95% of the field.
What causes Hydropic degeneration?
Hydropic degeneration is a result of ion and fluid homestasis that lead to an increase of intracellular water. The vacuolated swelling of the cytoplasm of the hepatocytes of the GNPs treated rats might indicate acute and subacute liver injury induced by the GNPs.
What is cell degeneration?
Nonlethal injury to a cell may produce cell degeneration, which is manifested as some abnormality of biochemical function, a recognizable structural change, or a combined biochemical and structural abnormality. Degeneration is reversible but may progress to necrosis if injury persists.
What is apoptosis & necrosis?
Apoptosis is described as an active, programmed process of autonomous cellular dismantling that avoids eliciting inflammation. Necrosis has been characterized as passive, accidental cell death resulting from environmental perturbations with uncontrolled release of inflammatory cellular contents.
What qualifies Dallas?
The Dallas criteria were proposed in 1986 and provided a histopathological categorization by which the diagnosis of myocarditis could be established. Dallas criteria myocarditis requires an inflammatory infiltrate and associated myocyte necrosis or damage not characteristic of an ischemic event.
What’s Hydropic degeneration?
What is difference between cell death and necrosis?
The main difference between apoptosis and necrosis is the mechanisms involved in the cell death. Apoptosis is a natural physiological process while necrosis is a pathological process, caused due to external agents like toxins, trauma, and infections.
What is hyaline degeneration?
Medical Definition of hyaline degeneration : tissue degeneration chiefly of connective tissues in which structural elements of affected cells are replaced by homogeneous translucent material that stains intensely with acid stains.
What does the medical term degenerative mean?
Listen to pronunciation. (deh-JEH-neh-ruh-tiv dih-ZEEZ) A disease in which the function or structure of the affected tissues or organs changes for the worse over time.
What does degenerative mean in biology?
In evolution, degenerate (in the sense of degeneration) refers to the state or process when an organism has lost one or more highly developed features. The feature may be a function or a structure.
