Maybe it is not so admired as the prospects for cancer treatment Cancer Treatment - difficult, but necessary   and restoration of the damaged spinal cord, but the branch of science dealing with the problem of aging, is also beginning to make active use of stem cells. The main objectives in this area - to slow or even reverse the aging process to wrap the man. Scientists are trying to find not only a means to an external rejuvenation and cure for diseases such as heart failure, Alzheimer's disease, stroke, Stroke - a serious brain injury , and so on. Perhaps, with the help of stem cells will be able to solve these problems.

Calling

As physicists are trying to find a general theory of all physicians and scientists trying to create a theory that would explain all the processes taking place in an aging body. Some experts believe that their main reason is the lack of activity of stem cells.

Stem cells are the basis for the development of living beings. Embryonic stem cells have the capacity to form cell types present in the body, while table cell adults can become a particular cell type. All stem cells are necessary in order that the body can continuously recover and to replace dead cells.

Most of the work on the study of stem cells is devoted to finding ways in which to stimulate the formation of these cells, all other cells - muscle, nerve, brain cells. If scientists succeed, these cells can replace cells in the body that no longer work properly. It is assumed that once it becomes a real opportunity to regenerate healthy tissue of the heart muscle after a heart attack, or reduce the symptoms of Alzheimer's disease Alzheimer's disease - can be slowed down, it can not be cured Replacing damaged brain cells.

At the same time, many scientists consider stem cells with a systemic point of view - they are interested in how we can use these cells to maintain the health of the aging body. For many years, canteens cells are considered a kind of "fountain of youth" - because of their ability to continuously divide and proliferate, giving the body life of fresh, healthy cells. The basic idea is that you can take advantage of the fountain of youth, if you constantly replace old cells with new ones.

The ability of stem cells to repair tissue and to replace damaged or dead cells over time weakens. It is now known that in the elderly the same number of stem cells, and how the young, and most of them - are in good condition. However, in the surrounding tissues it is something that inhibits stem cell and makes them less efficient. If there was a way to reactivate found stem cells, at least temporarily, it would open up opportunities for the treatment of geriatric diseases, many of which are related to the weakening of the body's ability to heal itself.

However, all this does not mean that it will be possible to completely cure Alzheimer's disease and enable people to live to 200 years.

Napping potential

In the application of stem cells have dormant potential that, if scientists can reveal it, will allow a significant impact on the recovery of tissues.

Even if the stem cells will not add decades to the human life they will give people a lot of healthy and productive years - in theory, people can actively work and live full lives without suffering from serious health problems, up to 70-80 years, and even longer.

As we age, many body systems start to work less effectively destroyed, or become more susceptible to various diseases. With the help of stem cells Stem cells: on the edge of scandal   this can be avoided.

Two mice

In 2005, scientists set up an experiment on two mice - young and old: they are (literally) sewed them together to connect their blood system. After some time the stem cells old mice became more active and healthy. This led scientists to conclude that the young blood and tissue had such an influence on stem cells of old mice.

After this experience, scientists began looking for a way to use the information obtained in the treatment of the elderly. It is possible that transplant young stem cell is able to accelerate healing, for example after a hip fracture or make muscle senescent stronger and less prone to damage.

It is unclear exactly when the broad masses of the people have the opportunity to rejuvenate with the help of stem cells, but it is assumed that it is a matter of a few years, or at most a pair of decades.

Organ transplantation - is, in fact, the replacement of the body that has ceased to function, a healthy body. Not all organs can be transplanted.

The most commonly transplanted organs following:

• Kidneys; it may be necessary in diseases such as diabetes, polycystic kidney Polycystic kidney disease: severe hereditary disease , Lupus, or other infringements.
• The liver, for example, cirrhosis, which can be caused by many reasons.
• Heart - due to coronary artery disease, cardiomyopathy, heart failure and other heart problems.
• Pancreas - transplant usually required due to diabetes.
• Light - in cystic fibrosis Cystic fibrosis: early diagnosis - the key to recovery , Chronic obstructive pulmonary disease (COPD), and other violations.
• Small intestine due to short bowel syndrome, caused by necrotizing enterocolitis, Crohn's disease and so on.

In one operation can be transplanted more than one body.

Not everyone is a good candidate for organ transplants. Typically, this operation does not like patients with various infections, uncontrolled heart disease and other serious diseases, as well as those who have alcohol or drug dependency.

If the results of examination of the patient is a suitable candidate for an organ transplant, his name are entered in the "waiting list". It may take several months or years Lager before held organ transplants.

The success of the operation

The techniques used for organ transplants, are constantly being improved, but the operation remains difficult and very dangerous. The success of organ transplantation depends on the following factors:

• Which organ is transplanted.
• How many organs are transplanted.
• Diseases that cause organ failure.

Preparing for organ transplants

First of all, the person who is to transplant organs, are doing all the tests necessary to find a suitable donor organ. Improper organ donor's immune system will reject that can lead to very serious health consequences.

In addition, the pre-transplant need to continue to closely monitor their health - to take the necessary medication, adhere to recommendations on exercise and nutrition.

Interview with psychiatrist or clinical psychologist is another important part of the training in organ transplants.

The duration of organ transplants, the degree of complexity, the duration of the recovery period depends on what kind of organ transplant, as well as the general health of the patient and other factors.

After transplantation

Many patients who have undergone organ transplants, said that for many years did not feel so good. This is not surprising, since the transplant in most cases preceded by a long illness.

For some time after the operation the patient must take drugs that suppress the immune system to prevent rejection of the donor organ. Gradually, the required dose of these drugs is reduced.

Because these drugs suppress the immune system, increases the risk of various infections. Because of this, patients are advised to avoid crowded places and take other precautions to protect themselves from infection.

The patient should undergo regular medical examinations to specialists to ensure how the new organ.

One of the common effects of organ transplants is depression. This may be due to the strong tension that preceded the operation, as well as many other factors. If any signs of depression Depression - a little more than a bad mood   should see a specialist without delay. The sooner you start treatment, the sooner you will cope with this disease.

Rejection of transplanted organs

As the perfect man can come only body of its twin, the immune system is always trying to tear the donation of organs. There are three basic types of organ rejection:

• Hyperacute rejection starts as soon as the donor organ enters the body. This is only possible if the body of the recipient already has antibodies that reject body; The reason for this can be incompatibility of blood donor and the recipient. Rejection of this type is practically nonexistent, as previously performed all analyzes required to prevent such reactions. If for any reason to prevent the rejection svehostroe failed, the patient is likely to die right on the operating table.
• Acute rejection begins a few days after surgery, when the body detects foreign material. This is a normal immune response with which to cope with the help of immunosuppressant.
• Chronic rejection - a gradual rejection of the donor organ, which can last months or years. For some time, the patient may not notice any effects of chronic rejection.

Who can be an organ donor

Most people can become organ donors. Some of them are in life. Many people decide that their organs after death can be used for transplantation to other people.

To be a donor in life, a person must be in good health, it should not be such disorders as diabetes, hypertension and mental illness Mental illness - ashamed to ask for help? . The donor must be at least 18 and no older than 60 years.

If a person has consented to the transplantation of organs after his death, the decision to use its organs depends largely on what state they are in, as well as from what was the state of health of the person at the time of death.
