Sickle Cell Disease

Sickle cubicle ailment can be define as acute terminal hemoglobinopathic anemic prepare , which affects pack with stable brokertic traces , for hemoglobin S or Hb S . The abnormality in hemoglobin levels results in torture of the erythrocytes . The distemper produces joint pains thrombosis and fever . Other symptoms allow chronic genus Anemia with splenomegaly , exhaustion and weakness ( reaping hook stall anemia , 2002These symptoms are normally present right from birth and whitethorn cause pallor , jaundice , breathlessness , enlarged short temper , fatigue and headaches . Any infection , dehydration or raw weather usually accelerates the crisis , which results in pain in the castanets , traces of blood in urine , and paralytic strokes or epileptic seizures . Deficiency of red blood cellphones or anemia is grim and reaping hook cell anemia causes pneumonia in children ( reaping hook-cell malady , 2000Sickle cell anemia is an asexual chromosomal transmissible ingredienttic disease Children with the disease must have inherited a imitation of the gene of hemoglobin trait from each parent . closely of the people carry one hemoglobin S gene without any considerable health problems caused by the Hb S . If both the parents are carriers of the sickle cell gene then the possibility of having children with sickle cell anemia is higher . This sickle cell gene trait is more prevalent in people belonging to certain ethnic populations . The Hb S gene is more concentrated in the people of horse opera Africa and eight percent of all African Americans are carriers of the sickle cell gene . It is more commonly present in people of Mediterranean countries , the Middle East , and India . It can in any case be present in people whose ancestors originated from these regions (Eckman 2005Sickle cell disease is an inherited dis of red blood cells and results in anemia and go on body pains . The trait of sickle cell gene is a result of a change catalyzed by a single nucleotide in the Hb S which causes the backup of glutamic dosage by valine as the sixth amino acid of Hb S .

The red blood cells containing the sickle cell hemoglobin S gene survive for a genuinely short period . Thus the resultant anemia and the touched rigidity of blood cells cause obstruction to the free rate of flow in small blood vessels (Sickle cell disease , 2004Children who had inherited one sickle gene and one normal Hb S gene develop simple heterozygous condition also known as sickle cell trait This condition does not develop into anemia or recurrent pain . High quantities of hemoglobin A in sickle cell trait red blood cells provides protection against the evil consequences of Hb S . Eventually homozygous sickle cell anemia causes sufficiently high levels of intracellular concentration of sickle cell Hb S with fatal consequences (Sickle cell disease , 2004One of the characteristics of the sickle cell Hb S is insolubility when deoxygenated . This keeping of the gene is responsible for the cause of disease . Further , oxygenated sickle cell Hb S is as soluble as oxygenated normal hemoglobin . If it is deoxygenated it forms an insoluble polymer . The process of polymerization of sickle cell Hb...If you want to get a full essay, outrank it on our website: Orderessay
