Imagine being the parent of a sick child dying of a curable disease and the only chance of survival is to find a near perfect-matched donor for blood and possibly bone marrow transplantation. After exhausting all the possible searches for a usable match and being unable to do so‚ you are told by the physician that there is a procedure that would be helpful. But this procedure would involve the conception of another child that would be the donor‚ starting at birth‚ for your dying child. What would

M5 Assignment: Anemia of Chronic Disease 1. Differentiate between absolute and functional iron deficiency in the context of ACD and IDA. Absolute iron deficiency is when the stores of iron are depleted and bone marrow iron is absent‚ resulting in low serum ferritin and low transferrin saturation. Simple absolute iron deficiency usually results in iron deficiency anemia and can be resolved with iron supplementation. Functional iron deficiency results in anemia of chronic disease/inflammation

Bone is a specialised‚ strong‚ flexible connective tissue and is the main component of the adult skeleton. Unlike hyaline and fibrocartilage‚ bone is supplied with nerves and blood vessels. Epiphyseal veins carry the blood away from the long bones of the body and periosteal arteries‚ which are also accompanied by nerves‚ carry blood to the bones. It provides support and gives the structural framework to the body‚ it acts as a protective cover for internal organs such as the heart‚ brain and lungs

Maksimov‚ proposed the hypothesis about existence of the stem cells and coiled the name for them. Later on‚ in 1963‚ Canadian Scientists‚ James E. Till and Ernest A. McCulloch actually demonstrated the existence of self-renewing cells found in the bone marrow of mice. ( Silverstein‚ 12) It is impossible to say who exactly the founder of the stem cells was. When it comes to such kind of discussion‚ it is better to say that a lot of scientists put a great effort to contribute and give development of this

and develops in the bone marrow. The bone marrow is the soft‚ spongy center of certain bones that produces the three major blood cells: white blood cells to fight infection; red blood cells that carry oxygen; and platelets that help with blood clotting and stop bleeding. When a child has leukemia‚ the bone marrow‚ for an unknown reason‚ begins to make white blood cells that do not mature correctly‚ but continue to reproduce themselves. • Leukemia is diagnosed by bone marrow aspiration or biopsy

clots to prevent blood loss. Red blood cells or erythrocytes develop in the bone marrow and transport oxygen from the lungs to the cells. RBCs also transport carbon dioxide from cells and into the lungs to be exhaled. White blood cells protect the body from infection. The most common type of WBC is neutrophil‚ the immediate response cell and accounts for 60-70% of the total WBC. Neutrophils last less than 1 day so the bone marrow must constantly make new neutrophils to maintain protection against infection

lymph cells: T cells and B cells. When B cells respond to an infection‚ they change into plasma cells. The plasma cells are found mainly in the bone marrow—the soft‚ inner part of some bones. The plasma cells make proteins called antibodies that attack and help kill germs. When plasma cells grow out of control‚ they can form a tumor‚ usually in the bone marrow. This type of tumor is called a myeloma‚ and if there are many tumors they are called multiple myeloma. If there is only one tumor‚ it is called

The development of lymphocytes is different to other elements because lymphocytes not only develop in bone marrow and finish in lympatic tissue. Other elements start and finish their development in bone marrow. 3. Erythropoiesis is the specific production of red blood cells. Negative feedback increases red blood cell production‚ but if the stimulus disrupts homeostasis then in decreases red blood cell
