Direct identification of sickle cell anemia by blot hybridization.

Direct identification of sickle cell anemia by blot hybridization.

Several reports have been published on the use of polymorphisms found in the human hemoglobin genes as a means for prenatal diagnosis of sickle cell anemia. The disadvantages of this approach reside in its limited application and the need for family analysis. Here we report that, by use of restriction endonuclease Dde I and diazobenzyloxymethyl-paper transfer procedures, a direct analysis can b...

Side Effects of Hydroxyurea in Patients with Sickle Cell Anemia

Background: Hemoglobin S arises is the result of a point mutation (A-T) in the sixth codon on the -globin gene on chromosome 11 causing sickle cell anemia. The presence of fetal hemoglobin in infancy plays a relatively protective role for vaso-occlusive symptoms that are the major contributor for the morbidity and mortality among patients with sickle cell anemia. hydroxyurea, an s-phase-specif...

Sickle Cell Anemia

We studied the role of the sodium-potassium pump in erythrocytes of 12 patients with sickle cell anemia (SS). Ouabain-binding sites per cell and pump-mediated Rb/K uptake were significantly higher in SS patients than in white or black controls. Ouabainresistant Rb/K influx was also greater than in normal controls or patients with sickle cell trait. Deoxygenation of SS erythrocytes increased oua...
