Necrosis is death of body tissue. It occurs when there is not enough blood flowing to the tissue, whether from injury, radiation, or chemicals. Necrosis is not reversible.
When substantial areas of tissue die due to a lack of blood supply, the condition is called gangrene.

Thyroid hormones for acute kidney injury
Acute kidney injury (AKI) has a number of causes including infection, trauma, kidney stones, toxic drugs, or acquired during hospital treatment. People with AKI suddenly lose kidney function leading to poor urine output and retention of body wastes. In every 1000 people who are discharged from hospital about 30 are diagnosed with AKI; about 6% of all critically ill patients have AKI. Many people with AKI will die from the disease.
