  1. GP lab I

  2. Cell Injury I

  3. normal cell mild damaging stimulus Sublethal cell injury Removal of cause of damage continued damage Reversible cell injury cell death Irreversible cell injury necrosis

  4. Cell Injury • Reversible • (Cell degeneration) • Irreversible (Cell death)

  5. Reversible injury(Cell degeneration) Degeneration = morphological changes in cells caused by sublethal injury

  6. Reversibleinjury • Cellular swelling (Cloudy swelling) • Hydropic degeneration • Fatty metamorphosis (Fatty degeneration)

  7. Cloudy swelling • Liver, Kidney, Heart • swelling of the cells • fine eosinophilic granular cytoplasm

  8. Hydropic degeneration • swelling of the cells • various sizes of vacuoles in cytoplasm

  9. Fatty metamorphosis • fat droplets in cytoplasm • pushing the nuclei to one side
