RA -
Noun: Abbreviation of Refractory Anaemia . One of the group of related bone marrow diseases under the heading of Myelodysplastic Syndromes.

RABBIT ALG -
Noun: Antilymphocyte Globulin produced from rabbits.

RAEB -
Noun: Abbreviation of Refractory Anaemia with Excess Blasts . One of the group of related bone marrow diseases under the heading of Myelodysplastic Syndromes.

RAEB-t -
Noun: Abbreviation of Refractory Anaemia with Excess Blasts in Transformation . One of the group of related bone marrow diseases under the heading of Myelodysplastic Syndromes.

RARS -
Noun: Abbreviation of Refractory Anaemia with Ringed Sideroblasts .

RBC -
Noun: Abbreviation of Red Blood Cell.

RED BLOOD CELL -
Noun: Red Blood cells ( Erythrocytes) are formed from the stem cells in the bone marrow by a process called erythropoiesis that takes about 5 days. Their normal life span is 120 days. About 3 million red blood cells are made by the stem cells every second to replace the 3 million that die every second. Their formation requires an adequate supply of nutrients, including iron, amino acids, and the vitamins B12 and folic acid. The rate at which RBCs are formed is influenced by a hormone called erythropoietin , which is produced by the kidneys. Red blood cells contain the iron-rich protein haemoglobin that carries oxygen to all tissues of the body. A shortage of red blood cells is known as anaemia. When a person is anaemic, they may feel dizzy, shortness of breath, and have headaches because they do not have enough oxygen circulating in their blood.

REFRACTORY -
Adjective: Not yielding to, or resistant to treatment.

Latin - re = back +
Latin - frangere = to break

REFRACTORY ANAEMIA -
Noun: A form of myelodysplasia often referred to as 'RA'. The fact that it is refractory indicates that it is resistant to treatment.

RENAL -
Adjective: Having to do with or located near the Kidneys such as a renal vein or a renal illness.

Latin - renalis = kidney

RETICULOCYTE -
Noun: A red blood cell that is not fully mature. It retains strands of nuclear material. Reticulocytes normally make up from 0.1 to 1 percent of the red blood cells in the body. See Haematopoiesis .

Latin - reticulum = net (taken from the net like appearance of the remaining nuclear material inside them) +
-cyte = a cell from Greek - kytos = anything hollow.

RH FACTOR -
Noun: An antigen found in the red blood cells of most human beings and the higher mammals. Blood containing this substance is Rh positive and does not combine favorably with blood which is Rh negative and lacks this substance. The presence or absence of the Rh factor is governed by a dominant gene, which means that when Rh-positive and Rh-negative genes are paired, the resulting children are always Rh-positive.

From 'Rhesus monkey', which is a small yellowish-brown monkey with a short tail, found in India. It is often used in medical research. This blood factor was first found in the blood of the rhesus monkey.

RUTH MYLES UNIT (ST. GEORGE'S) -
This Department of St. George's hospital in London, England, headed by Professor Ted Gordon-Smith and Doctor Judith Marsh, is a leading international centre for research on blood cell formation, bone marrow failure syndromes and bone marrow transplantation and is supported by multiple research grants including the Aplastic Anaemia Trust .

The largest topic of research in this Department is Aplastic Anaemia. The work carried out at the Ruth Myles Unit is shared with consultants throughout the UK.

St. George's hospital is right across from Tooting Broadway underground station. See St. George Hospital for map
