Allotransplantation

**Allotransplantation** is the transplantation of a part or an entire organ from one person to another. Transplanted organs, tissues, cells, drugs for cell replacement therapy, etc. must be taken from living people who are not relatives of the recipient. The surfaces of organs are removed under sterile conditions immediately after the death of the donor; preservation of organs during storage before surgery should ensure their functional suitability. In order to ensure the functioning of the transplanted organ according to the type of compartmentally damaged parenchyma, germinoplasty (ovarian and adrenal gland transplantation) is also used. Restorative procedures last for at least a week, during which the patient takes immunosuppressive therapy. If the transplant did not take root or was not available, they switch to using allogeneic organs from dying or deceased patients with chronic renal failure. Bone marrow allotransplantation is possible. However, the procedure is complex because it uses incompatible lymphocytes from the patient, which can cause rejection. Due to the need to combine when transplanting a small part or part of an organ (for example, the cornea or skin), the operation is sometimes performed in a coexisting graft or from an organ taken in this condition; To achieve this, surgical or chemotherapeutic reduction of viability is performed. A prosthetic transplant is an analogue organ created experimentally
