4.6. detachment of ribosomes from RER

4.7. Accumulation of lactate

4.8. intra celler lactic acidosis

4.9. decreased protein syntheis

5. 5 morphology

5.1. acute cellular swelling due to influx of water

5.2. cell memebrane and cytoplasm = blebbing

5.3. fatty changes apparance of lipid vacuoles in cytoplasm

5.4. Nucleus and mitochondria: NO change

6. 6 Reperfusion Injury MCHIN

6.1. = BLood got back to the tissue

6.2. 1 calciom overload lead to

6.2.1. + lipid peroxidation
