Hemotherapy
Hemotherapy ( ) or hemotherapeutics ( ) is the treatment of disease by the use of blood or blood products from blood donation ( by others or for oneself). It includes various types, such as: * Blood transfusion * Packed red blood cells transfusion * Fresh frozen plasma transfusion * Plasmapheresis Plasmapheresis (from the Greek language, Greek πλάσμα, ''plasma'', something molded, and ἀφαίρεσις ''aphairesis'', taking away) is the removal, treatment, and return or exchange of blood plasma or components thereof from and to the ... of various kinds, including plasma exchange * Autohemotherapy, with autologous blood that is usually modified in some way References Transfusion medicine {{treatment-stub ...

Autohemotherapy
Autologous blood therapy, also known as autologous blood injection or autohemotherapy, comprises certain types of hemotherapy using a person's own blood ('' auto-'' + '' hemo-'' + ''therapy''). There are several kinds, the original belonging only to traditional medicine, alternative medicine, and some newer kind of medicine under investigation. The original, unscientific form is "the immediate intramuscular or subcutaneous reinjection of freshly drawn autologous blood". It was used in the early 20th century, when some physicians believed that it had efficacy and a logical mechanism of action; it was abandoned as advancing science made clear that it lacked those.

Packed Red Blood Cells
Red blood cell concentrates, also known as red cell concentrates or packed red blood cells, are red blood cells that have been separated for blood transfusion. A red blood cell concentrate typically has a haematocrit of 0.50 – 0.70 L/L and a volume between 250 and 320 mL. Transfusion of red blood cell concentrates is indicated to compensate for a deficit caused by critical bleeding or to correct anaemic conditions, in order to increase the oxygen-carrying capacity and avoid detrimental effects caused by oxygen debt. In adults, one unit brings up hemoglobin levels by about 10 g/L (1 g/dL). Repeated transfusions may be required in people receiving cancer chemotherapy or who have haemoglobin disorders. Cross-matching may be required before the blood is given. A red blood cell concentrate is given by injection into a vein. The widespread use of red blood cell concentrates as part of blood component therapy began in the middle of the 20th century, when polyvinyl chloride (PVC ...

Autotransplantation
Autotransplantation is the transplantation of organs, tissues, or even particular proteins from one part of the body to another in the same person ('' auto-'' meaning "self" in Greek). The autologous tissue (also called autogenous, autogeneic, or autogenic tissue) transplanted by such a procedure is called an autograft or autotransplant. It is contrasted with allotransplantation (from other individual of the same species), syngeneic transplantation (grafts transplanted between two genetically identical individuals of the same species) and xenotransplantation (from other species). A common example is the removal of a piece of bone (usually from the hip) and its being ground into a paste for the reconstruction of another portion of bone. Autotransplantation, although most common with blood, bone, hematopoietic stem cells, or skin, can be used for a wide variety of organs. One of the rare examples is autotransplantation of a kidney from one side of the body to the other. Kid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disease
A disease is a particular abnormal condition that adversely affects the structure or function (biology), function of all or part of an organism and is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergy, allergies, and autoimmune disorders. In humans, ''disease'' is often used more broadly to refer to any condition that causes pain, Abnormality (behavior), dysfunction, distress (medicine), distress, social problems, or death to the person affected, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injury in humans, injuries, disability, disabilities, Disorder (medicine) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blood
Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells. Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, and hormones. The blood cells are mainly red blood cells (erythrocytes), white blood cells (leukocytes), and (in mammals) platelets (thrombocytes). The most abundant cells are red blood cells. These contain hemoglobin, which facilitates oxygen transport by reversibly binding to it, increasing its solubility. Jawed vertebrates have an adaptive immune system, based largely on white blood cells. White blood cells help to resist infections and parasites. Platelets are important in the clotting of blood. Blood is circulated around the body through blood vessels by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blood Transfusion
Blood transfusion is the process of transferring blood products into a person's Circulatory system, circulation intravenously. Transfusions are used for various medical conditions to replace lost components of the blood. Early transfusions used whole blood, but modern medical practice commonly uses only components of the blood, such as red blood cells, blood plasma, plasma, platelets, and other clotting factors. White blood cells are transfused only in very rare circumstances, since granulocyte transfusion has limited applications. Whole blood has come back into use in the Major trauma, trauma setting. Red blood cells (RBC) contain hemoglobin and supply the Cell (biology), cells of the body with oxygen. White blood cells are not commonly used during transfusions, but they are part of the immune system and also fight infections. Plasma is the "yellowish" liquid part of blood, which acts as a buffer and contains proteins and other important substances needed for the body's overall ...

Blood Product
A blood product is any therapeutic substance prepared from blood, usually human blood; in some medicolegal contexts, the term refers specifically to human-blood-derived products. Blood products include whole blood, blood components, and blood plasma derivatives. Blood components include red blood cell concentrates or suspensions; platelets produced from whole blood or via apheresis; granulocytes; fresh frozen plasma; cryoprecipitates; antisera; and others. Some products for topical use, such as serum eye drops, have also been recently classified as blood components. Plasma derivatives are plasma proteins prepared under pharmaceutical manufacturing conditions, including: albumin; coagulation factor concentrates; and immunoglobulins. __TOC__ Relation to other substances Blood products may also be called blood-based products or blood-derived products. to differentiate them from blood substitutes, which generally refer to artificially produced products.

Blood Donation
A 'blood donation'' occurs when a person voluntarily has blood drawn and used for transfusions and/or made into biopharmaceutical medications by a process called fractionation (separation of whole blood components). A donation may be of whole blood, or of specific components directly ( apheresis). Blood banks often participate in the collection process as well as the procedures that follow it. In the developed world, most blood donors are unpaid volunteers who donate blood for a community supply. In some countries, established supplies are limited and donors usually give blood when family or friends need a transfusion (directed donation). Many donors donate for several reasons, such as a form of charity, general awareness regarding the demand for blood, increased confidence in oneself, helping a personal friend or relative, and social pressure. Despite the many reasons that people donate, not enough potential donors actively donate. However, this is reversed during dis ...

Allotransplantation
Allotransplant (''allo-'' meaning "other" in Greek) is the transplantation of cells, tissues, or organs to a recipient from a genetically non-identical donor of the same species. The transplant is called an allograft, allogeneic transplant, or homograft. Most human tissue and organ transplants are allografts. It is contrasted with autotransplantation (from one part of the body to another in the same person), syngenic transplantation of isografts (grafts transplanted between two genetically identical individuals) and xenotransplantation (from other species). Allografts can be referred to as "homostatic" if they are biologically inert when transplanted, such as bone and cartilage.(W. P. Longmire, ''J. National Cancer Institute'' 14, 669: ''The term ''homostatic graft'' might be applied to inert tissues such as bone and cartilage when transferred from one individual to another of the same species; and the term ''homovital graft'' might be used in reference to grafts whose ...

Fresh Frozen Plasma
Fresh frozen plasma (FFP) is a blood product made from the liquid portion of whole blood. It is used to treat conditions in which there are low blood clotting factors (INR > 1.5) or low levels of other blood proteins. It may also be used as the replacement fluid in plasma exchange. Using ABO compatible plasma, while not required, may be recommended. Use as a volume expander is not recommended. It is administered by intravenous, slow injection into a vein. Side effects include nausea and itchiness. Rarely there may be allergic reactions, blood clots, or infections. It is unclear if use during pregnancy or breastfeeding is safe for the baby. Greater care should be taken in people with protein S deficiency, IgA deficiency, or heart failure. Fresh frozen plasma is made up of a complex mixture of water, proteins, carbohydrates, fats, and vitamins. When frozen it lasts about a year. Plasma first came into medical use during the Second World War. It is on the WHO Model List of Essenti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plasmapheresis
Plasmapheresis (from the Greek language, Greek πλάσμα, ''plasma'', something molded, and ἀφαίρεσις ''aphairesis'', taking away) is the removal, treatment, and return or exchange of blood plasma or components thereof from and to the circulatory system, blood circulation. It is thus an extracorporeal therapy, a medical procedure performed outside the body. Three general types of plasmapheresis can be distinguished: * ''Autologous'', removing blood plasma, treating it in some way, and returning it to the same person, as a therapy. * ''Exchange'', a patient's blood plasma is removed, while blood products are given in replacement. This type is called plasma exchange (PE, PLEX, or PEX) or plasma exchange therapy (PET). The removed plasma is discarded and the patient receives replacement donor plasma, albumin, or a combination of albumin and saline (medicine), saline (usually 70% albumin and 30% saline). * ''Donation'', removing blood plasma, separating its components, and ...
