Morphology of cell injury and Intracellular accumulationspptxvaishaliwasnik
MORPHOLOGY OF REVERSIBLE CELL INJURY
Common examples of morphologic forms of reversible cell injury are as under:
Hydropic change
2. Hyaline change
3. Mucoid change
4. Fatty change (discussed under intracellular accumulations)
1. HYDROPIC CHANGE
Hydropic change means accumulation of water within the cytoplasm of the cell.
Other synonyms used are cloudy swelling (for gross appearance of the affected organ) and vacuolar degeneration (due to cytoplasmic vacuolation).
Hydropic swelling is an entirely reversible change upon removal of the injurious agent.
ETIOLOGY
This is the commonest and earliest form of cell
injury from almost all causes.
The common causes include acute and subacute cell injury from various etiologic agents such as bacterial toxins, chemicals, poisons, burns, high fever, intravenous administration of hypertonic glucose or saline etc.
PATHOGENESIS
Cloudy swelling results from impaired
regulation of sodium and potassium at the level of cell membrane.
This results in intracellular accumulation of sodium and escape of potassium.
This, in turn, is accompanied with rapid flow of water into the cell to maintain iso-osmotic
2. HYALINE CHANGE
The word ‘hyaline’ or ‘hyalin’ means glassy (hyalos = glass).
Hyalinisation is a common descriptive histologic term for glassy, homo geneous, eosinophilic appearance of proteinaceous material in haematoxylin and eosin-stained sections and does not refer to any specific substance.
Though fibrin and amyloid have hyaline appearance, they have distinctive features and
staining reactions and can be distinguished from non-specific hyaline material.
Hyaline change is seen in heterogeneous pathologic conditions and may be intracellular or extracellular.
INTRACELLULAR HYALINE
Intracellular hyaline is mainly seen in epithelial cells.
1. Hyaline droplets in the proximal tubular epithelial cells due to excessive reabsorption of plasma proteins in proteinuria.
2. Hyaline degeneration of rectus abdominalis muscle called Zenker’s degeneration, occurring in typhoid fever. The muscle loses its fi brillar staining and becomes glassy and hyaline.
3. Mallory’s hyaline represents aggregates of intermediate filaments in the hepatocytes in alcoholic liver cell injury.
4. Nuclear or cytoplasmic hyaline inclusions seen in some viral infections.
5. Russell’s bodies representing excessive immuno glo bulins in the rough endoplasmic reticulum of the plasma cell
EXTRACELLULAR HYALINE
Extracellular hyaline commonly termed hyalinisation is seen in connective tissues.
1. Hyaline degeneration in leiomyomas of the uterus.
2. Hyalinised old scar of fi brocollagenous tissues.
3. Hyaline arteriolosclerosis in renal vessels in hyper tension and diabetes mellitus.
4. Hyalinised glomeruli in chronic glomerulonephritis.
5. Corpora amylacea seen as rounded masses of concentric hyaline laminae in the enlarged prostate in the elderly, in the brain and in the spinal cord in old age, and in old infarcts of the
lung.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.
