Necrosis
vs. Apoptosis
Unless you are in the medical field, necrosis and apoptosis can seem like fancy words for a disease that you may never get. Think again. Both of these infections are on a cellular level and are common among people with various diseases and injuries. Apoptosis and necrosis are related to the death of otherwise healthy cells, either by internal causes or external causes. Someone who suffers either at a grand scale level can even die if they are not treated by a physician soon enough.

Apoptosis
is the planned cell death within organisms that are multi-cellular. These
cellular changes are done to the advantage of the organism, and do not involve
any cellular trauma or damage to the organism. Some of the ways that apoptosis
occurs includes cell shrinkage, nuclear fragmentation, condensation of the
chromatin in the cell and fragmentation of the DNA chromosomes. The changes
which cause apoptosis are all biochemical and involve the morphology and death
of cells within certain organisms. The death of a cell can occur in many
fashions. The first is that the cell contents leak out and cause inflammation
of the tissues in the surrounding area. They can also swell by themselves, which
can lead to an eruption or a slow leak of cell contents. Patients who have AIDS
or are HIV positive will have cells that suffer from apoptosis in random areas
throughout their body.
Necrosis
is different from apoptosis in that the cell has not lived out its life. There
is an outside cause for the reason that the cell has died. Necrosis is the
death of cells and living tissue from something that has attacked the cellular
ability to complete mitosis. Toxic elements, infections, and trauma are often linked
to necrosis occurring in patients most frequently. Unlike the cells that
undergo apoptosis, cells that succumb to necrosis are not supposed to die,
which could have a larger and more deadly effect on the patient. Phagocytes are
not able to engulf the cell that is dead, therefore dead tissue and cell debris
build around the area where the first cell was located. This can mean
amputation of an arm or leg, or death if the necrosis occurs in the torso near
vital organs of the body.
While
apoptosis and necrosis are two very different problems for the cells of humans,
they are no laughing matter and should be taken very seriously.
Summary
1.
Apoptosis and necrosis are both involved in the death of cells. Apoptosis cells
are damaged by a planned death, these cells are expected to die for some
reason. A necrosis cell is suddenly killed by an outside source.
2. Apoptosis cells can shrink or fragment into pieces. Necrosis cells can leak out or even rupture.
3. Apoptosis is common in patients who suffer from AIDS or are HIV positive. Necrosis is often seen in patients who have cancer, or even those who have been bitten by a poisonous insect or reptile.
