Necrosis can be caused by external or internal factors. External factors include blood vessels damage, mechanical trauma, and ischemia. Extremely high or low temperature can cause disruption of cells, which may result in necrosis. Internal factors like trophoneurotic disorder, pancreatic enzymes, injury and paralysis of nerve cells can also cause necrosis. Sometimes steroids can also cause necrosis.
Necrosis: The death of living cells or tissues. Necrosis can be due, for example, to ischemia (lack of blood flow). From the Greek "nekros" (dead body). It's skin death and looks like dried blood underneath the skin (black like a bruise) at first and can progress.
Cystic medial necrosis has no known cause. It is diagnoses by thickening of the muscle fibers in the aorta accompanied by the accumulation of mucopolysaccharide.
Extravasation can cause tissue necrosis.
Liquefactive necrosis is good for your body, especially your brain (due to the beneficial liquids produced) but coagulative necrosis is bad due to the clumping and coagulation (i.e. clotting) that occurs.Coagulation necrosis is the "acute" necrosis in which the protein fibers become denatured and everything turns into a semi-solid mess of dead tissue. Liquefactive necrosis is a more "chronic" necrosis in which the dead tissue is digested into a liquid which can then be removed by the macrophages.
A horned spider is not deadly to humans although the venom can cause necrosis.
It is the tumor necrosis factor
The use of Prednisone can cause Avascular Necrosis. This would affect the bone area. It has been reported that those who have taken doses greater then 20 milligrams a day of Prednisone have experienced this condition, particularly in the hip area.
Necroses is the plural of necrosis
The Black Widow spider and the Redback Spiders are two spiders whose bites can cause necrosis by working directly on the nervous system causing paralysis and effects on the cardiorespiratory system.
The correct spelling is "necrosis".
If given in a concentration over 40mEq/l per peripheral line, or over 20mEq/100ml by central line, KCl can be sufficiently injurious as to cause phlebitis or even necrosis, especially if the solution infiltrates outside the vessel.
Necrosis is tissue death. It is common to find necrosis in the extremities, however necrosis can result from damage or disease in any living tissue or body part.
Fat necrosis is one of many types of necrosis. Necrosis is cell death with inflammation (different from apoptosis, which is without inflammation). Fat necrosis occurs in two forms. 1. Traumatic fat necrosis is the result of trauma. Cellular damage to fat-rich organs, such as the breasts, can lead to necrosis of the adipocytes. 2. Fat necrosis as a result of acute haemorrhagic pancreatitis. In this case, damage to the pancrease releases lipolytic enzymes into the blood, causing damage, and eventual necrosis of adipocytes.
