What does bone marrow transplantation mean

summary

The only way to treat leukemia now is bone marrow transplantation, or chemotherapy, especially to hurt the body. Recently, my colleagues' children have been looking for bone marrow, and I'd like to explain the related knowledge of bone marrow transplantation to you.

What does bone marrow transplantation mean

First of all, bone marrow transplantation is the treatment of transplanting donor's normal bone marrow cells through intravenous injection to patients with hematologic diseases such as leukemia or aplastic anemia. In addition to bone marrow, hematopoietic stem cells used in bone marrow transplantation can also be obtained by recovering PBSCT or umbilical cord blood from peripheral blood. This is the only way to treat leukemia, and the only way to save patients with leukemia.

Secondly, bone marrow is a kind of spongy tissue existing in the bone marrow cavity of long bones (such as humerus and femur) and in the eyes of cancellous interosseous reticulum of flat bones (such as ilium, ribs, sternum, spine, etc.). The bone marrow that can produce blood cells is slightly red, which is called red bone marrow. Some of the adult bone marrow cavity bone marrow contains many fat cells, yellow, and can not produce blood cells, known as yellow bone marrow. When a person is born, the marrow cavity of the whole body is full of red bone marrow. With the growth of age, the number of fat cells in the marrow increases, and a considerable part of the red bone marrow is replaced by yellow bone marrow. Finally, almost only flat bone and cancellous bone have red bone marrow. This change may be due to the fact that adult does not need all the marrow cavity hematopoiesis, and part of the marrow cavity hematopoiesis is enough to supplement the required blood cells. When the body is severely ischemic, part of the Yellow bone marrow can be transformed into red bone marrow, and the ability of hematopoiesis can be restored.

Finally, bone marrow transplantation is a kind of practical treatment method of organ transplantation, in which normal bone marrow is intravenously injected into patients to replace diseased bone marrow. It is used to treat many cases of hematopoietic dysfunction, immune deficiency, hematological malignancies and other malignancies. This treatment can improve the curative effect, improve the prognosis, and obtain long-term survival and even radical cure.

matters needing attention

The reason for the failure of transplantation may be that the patient has received multiple blood transfusions, and the chemistry of hematopoiesis and immune cells. The radiation after my transplantation is not strong enough, and the bone marrow transfused is not enough. Drug damage to bone marrow and so on. To maintain a good mood, to actively improve immunity, do not eat some miscellaneous food, to pay attention to bed rest.
