Bone Marrow Transplant Quiz!

Explanation
Bone marrow is a spongy, fatty tissue that is found in the largest bones of the body. It is responsible for producing blood cells, including red blood cells, white blood cells, and platelets. Bone marrow also contains stem cells, which are important for the growth and repair of tissues.

Explanation
In 1956, the first truly successful bone marrow transplant took place. This medical procedure involves the transplantation of healthy bone marrow cells to replace damaged or destroyed cells in the recipient's bone marrow. The success of this transplant marked a significant advancement in the field of medicine and opened up new possibilities for treating various diseases, particularly those affecting the blood and immune system.

Explanation
The correct answer is Early 20th century. This is because the first successful bone marrow transplant was performed in 1956 by Dr. E. Donnall Thomas. Although there were earlier attempts at bone marrow transplantation in the late 19th and early 20th century, they were not successful. It was not until the mid-20th century that advancements in medical technology and understanding of immunology allowed for successful bone marrow transplants.

Explanation
Fredrick Helsing is not an important name in bone marrow transplant history. The other four names mentioned, Donnall Thomas, Jean Dausset, Robert Good, and Joseph Murray, are all significant figures in the history of bone marrow transplantation. Donnall Thomas pioneered the use of bone marrow transplantation as a treatment for leukemia, Jean Dausset discovered human leukocyte antigens (HLAs) which are crucial for matching donors and recipients, Robert Good contributed to the development of bone marrow transplantation as a treatment for immunodeficiency disorders, and Joseph Murray performed the first successful kidney transplant, which laid the foundation for later advancements in transplantation medicine.

Explanation
Autologous bone marrow transplant is a type of transplant where the patient receives their own bone marrow. In this procedure, the patient's bone marrow is collected before undergoing high-dose chemotherapy or radiation therapy. The collected bone marrow is then stored and later infused back into the patient's body. This type of transplant eliminates the risk of rejection or graft-versus-host disease, as the patient's own cells are used. It is commonly used in the treatment of certain cancers and other diseases.

Explanation
David Stahl suffered from lymphoma, which is a type of cancer that affects the lymphatic system. The lymphatic system is responsible for fighting off infections and diseases, but when lymphoma occurs, abnormal cells start to grow in the lymph nodes and other lymphatic tissues. This can lead to symptoms such as swollen lymph nodes, fatigue, and weight loss. Treatment for lymphoma can include chemotherapy, radiation therapy, and in some cases, stem cell transplantation.
