Who are suitable for bone marrow donation, and what are the harms and benefits of bone marrow donati

In good shape. There are no chronic diseases of any kind.

The good is love, but the disadvantage is that if you have to say that there is, it hurts.

In fact, it is similar to the principle of blood donation.

Blood cells have blood types.

There are also types of white blood cells.

Not too much more elaborate.

Rejection is more likely to occur.

Both blood cells and white blood cells in the human body have the function of remodeling.

So just donate one after another to recover well.

It's not harmful to the body.

Also, if you are a man, donating more blood is more beneficial to your body than for women.

...... to prevent cancerI won't say much about the specifics.

You didn't ask about that.

What we need to transplant is hematopoietic stem cells from the bone marrow, and now there are two ways to extract such stem cells: the first is to extract the bone marrow hematopoietic stem cells, which are extracted from the iliac bone after the donor is anesthetized; The second is to collect peripheral blood hematopoietic stem cells, inject mobilizer into the donor to mobilize a large number of hematopoietic stem cells in the bone marrow blood into the peripheral blood, and collect 50 100 ml of whole blood directly from the vein of the donor's arm (note: ordinary blood donation volunteers usually need to donate 200 400 ml, and the amount of 100 ml is equivalent to a small bag of ordinary milk), extract 100 ml of hematopoietic stem cells through a blood cell separator, and at the same time transfuse other blood components back into the donor's body.

In the former way, volunteers need anesthesia and hospitalization, while in the latter way, volunteers do not need anesthesia and hospitalization, and there is no pain, and the volunteers of the China Bone Marrow Bank donate hematopoietic stem cells through the second way.

Through the enrichment of blood cell separators, the remaining blood is transfused back into the human body, which does not affect health at all.

Donating bone marrow does not affect a person's physical health. Many people think that donating bone marrow is extracting spinal cord, which is a complete misconception. A bone marrow transplant requires the body's red bone marrow – hematopoietic stem cells.

An adult's bone marrow weighs 3 kilograms, and less than 10 grams of bone marrow hematopoietic stem cells from a donor can save the life of a leukemia patient. Therefore, it does not weaken its immune function and hematopoietic ability.

Bone marrow is a tissue with strong regenerative ability, and the average healthy person can make up for the donated stem cells in about ten after donating hematopoietic stem cells.

Hello Bone marrow donation has some damage to the body, but it is within the scope of recovery. If it can help the dying patient, it is still very valuable. Hope.

The normal donation of bone marrow does not have much impact on the body, because our body has the ability to repair itself, especially the bone marrow, and everyone's bone marrow can be regenerated. Generally speaking, young people or young people can restore normal bone marrow as long as they maintain proper exercise and pay attention to nutritional supplementation after donating bone marrow, so they may not be suitable for the short term after donating bone marrow, but they will recover their bone marrow by themselves in the long term.

Because when donating bone marrow, the hospital will conduct strict screening on donors, if there is a disease or the body is relatively weak, older people will be excluded, so they do not meet some specific processes of bone marrow donation. Only some people who are of the right age and have strong physical fitness can meet the bone marrow donation process. After they complete the bone marrow donation, they generally have to carry out some restorative activities and maintain a certain amount of exercise every day, so that in the near future, their bone marrow will grow again and they can return to their previous state.

So this is a very complicated issue, only those who meet the basic requirements can donate bone marrow, and after donating bone marrow, the impact on people is generally not too great, and it will not affect people's physical health.

And some older people who are older, generally they will not meet the donation target, so they will not donate bone marrow. If young people donate bone marrow, under a certain amount of exercise and recovery, they can recover in a short time, because bone marrow can be regenerated, as long as you donate bone marrow, you can have a good effect on your body, not only will not harm the body, but may also help the body to a certain extent. Therefore, when we donate, we can deal with it according to our actual situation, and if our physical conditions do not allow it, then we should maintain a cautious attitude and do not do risky things.

Dedicating one's bone marrow to the patients and rescuing those dying brothers and sisters is what a noble act of the erection group! With the development of bone marrow transplantation, more and more people have responded to the work of bone marrow donation. However, there are also many people who do not understand the process of marrow donation and lack knowledge in this area, and they are worried about whether marrow donation will affect their health.

Actually, this worry is unnecessary.

Many different types of blood cells in our body come from the same ancestor, superfluous orange hematopoietic stem cells. Not only can he continue to differentiate his offspring, but he can also reproduce cells that are exactly the same as his own. As a result, our hematopoietic function is endless.

When the old blood cells die, new ones grow in their place; When some hematopoietic stem cells are damaged, healthy stem cells are born soon to compensate for them. Our bodies work so well together. Pluripotent stem cells are not very numerous and are distributed throughout the bone marrow.

When donating bone marrow, only a small part of the bone marrow of the human body is extracted, and only a part of the pluripotent stem cells are lost, and the remaining pluripotent stem cells will be quickly replicated, and the hematopoietic function will completely return to normal in a short period of time. Therefore, bone marrow donation will not affect the hematopoietic function of the person.

Some people are afraid of the operation of donating bone marrow, and the following is an introduction to the operation of bone marrow collection: the donor is considered qualified by a comprehensive physical examination and then carried out under continuous epidural anesthesia or general anesthesia (the anesthesia method is the same as that of general surgery), and the part of bone marrow collection is mostly used in the iliac bone, which is commonly known as the large hip bone, and there are also sternum. The method of marrow collection is similar to that of a bone marrow aspirate.

A needle is used to aspirate several milliliters of bone marrow fluid. The amount of bone marrow taken depends on the patient's weight and the number of cells in the donor's bone marrow fluid. The number of bone marrow cells transfused should not be less than kilogram of the patient's body weight, and if it is too small, it is not easy to be transplanted successfully.

Therefore, adults generally need to donate about 800-1000 ml of bone marrow. In fact, there is a large amount of blood mixed with so much bone marrow fluid, so it is necessary to have a proper blood transfusion during the operation. When the number of cells reaches the required level, the operation is over.

After surgery, there will be pain in the surgical area due to the large number of puncture points, which usually disappears within two weeks. Many donors are able to return to work within 3-4 days after surgery, with the youngest donors being in the range of months. These all indicate that donating bone marrow is safe for healthy people.

Dear readers, you probably don't worry much anymore after reading the above, do you? When your friends or loved ones need it, you're going to lend a helping hand, right?
