Correspondence MEDICALTJOSRNAL 559 Acquired Pure Red Cell Aplasia SIR,-May we make the following observation about your article on acquired pure red cell aplasia and its treatment with steroids (6 April, p. 3) ? A pure red cell aplasia that responded to riboflavine or prednisone has been described in African adults and in children with marasmus and kwashiorkor.' In marasmus and kwashiorkor an e...

Red blood cell (RBC) transfusion therapy is used in the clinical setting for a variety of indications, including patient resuscitation, augmentation of oxygen delivery, and to reverse or alleviate the symptoms of anemia [1–5]. Despite calls for a more conservative approach to blood transfusion as early as the late 1950s [6,7], the trend toward more cautious transfusion practices did not begin u...

Normal red blood cells in dogs contain stroma in fairly uniform amounts. This red cell stroma is rich in proteins and lipides. Anemia due to blood loss causes an increase in stroma protein. The highest levels of stroma protein are found in the severe anemias. As the anemia is corrected by red cell regeneration, the stroma protein level falls to normal. Anemia due to blood destruction (phenylhyd...

Red cell aplasia in children is a condition characterised by failure of erythropoiesis, with normal production of white blood cells and platelets. The disorder is either acquired or constitutional (congenital or inherited). The constitutional disorder is usually permanent, while the acquired variety is often transient, and thereby differs from adult pure red cell aplasia. As the treatment and p...

The human red blood cell is readily available in a wide range of quantities and can be processed to a highly purified single cell suspension. It normally converts glucose almost quantitatively to lactic acid, and this conversion appears to be a predominant fraction of the total metabolic activity (1). Because of these characteristics the human red cell provides a convenient material for the stu...

Diadema setosum (Leske, 1778), is one of the common echinoids widely distributed in the Indo-West Pacific Ocean, where it occurs from the Red Sea, Persian Gulf and the east coast of Africa to Japan, Australia and Malaysia. To investigate the developmental basis of morphological changes in embryos and larvae, we documented the ontogeny of D. setosum in a controlled laboratory condition at the In...

To test the hypothesis that haemoglobin concentration is a poor predictor of benefit from transfusion in preterm infants, and that red cell volume is the most important indicator of anaemia, 24 preterm infants receiving red cell transfusions had red cell volume, haemoglobin concentration, and cardiac output measured before and after transfusion. Red cell volume was measured either using dilutio...

environmental pollution plays a destructive role in the daily life of industrialized communities and due to their negative impact on the society they are always under close investigation.  besides well-known pollutants substantial, all major international health organizations consider noise pollution as an important health problem. in this study, we have used an animal model to study the effect...
