Hemolytic Anemia: Sickle Cell Anemia

Hemolytic anemia: Sickle Cell Anemia Sickle cell anemia is an autosomal recessive disorder caused prayers The gene defective copy of the inheritance of hemoglobin, respectively From Single Parents. The defects of hemoglobin, called hemoglobin S (HbS), become stiff and form a Crescent Demolition configuration if exposed to low oxygen levels. Oxidative stress also triggers Additions glycation Production Kesawan will enter into circulation, thereby worsening the individual vascular pathology ON The Sickle cell anemia. Red Blood Cells Sickle cell anemia AT husband lost the ability to pass through New Media Operating Winx narrow vessels and consequently trapped in Kesawan microcirculation. Husband it causes blockage of blood flow to the underlying network, consequently Pain Occur Network BECAUSE ischemia.
Although Sickle cell shape can be reversible or tax Husband Reported to its original shape if it was reported normal hemoglobin saturation, Very Fragile Crescent cells and LOT is well broken in Kesawan Very Small vessels, causing anemia. Cells that had been destroyed filtered and transferred to Kesawan circulation of Spleen; conditions resulted Spleen husband works more vehicles. Myocardial scar tissue and sometimes (cell death is well) Of the various organs, especially spleen and bones, can occur. Multiorgan dysfunction is often the case a few years taxable income.

What conditions can stimulate other cells BETWEEN Crescent hypoxia, anxiety, Cold Fever, and exposed. BECAUSE Spleen merupa his immune organ parts which, infections, mainly caused by bacteria Yang, general and Sickle cell crisis is often stimulating.

At birth, a sign of sickle cell anemia may not be seen because all babies have high levels of different types of hemoglobin, fetal hemoglobin (F). fetal hemoglobin do not sickle-shaped, but only survive in a time of approximately 4 months after birth. At the time this is a sign of the disease began to appear. These signs include the classic symptoms and signs of anemia associated with blockage of the characteristics of a very painful disorder.

Individual people with sickle cell anemia carry two defective genes and consequently have only hemoglobin S. Individuals who are heterozygous for sickle cell gene (carry one defective gene is said to bring the nature of sickle cell. heterozygous hemoglobin S is usually described in about 30 to 40% red blood cells, with normal hemoglobin carried by red blood cells left. Individuals are usually asymptomatic unless exposed with low oxygen levels, especially when exercising.

Demographic Roots of sickle cell anemia may be tracked in malaria endemic areas. The nature of sickle cell proved to provide protection against damage to red blood cells after infection with a microorganism responsible for causing malaria. Suspected that this protection allows the cells to survive genes during the process of evolution in malaria endemic areas, such as the equator in Africa. While in the United States, sickle cell anemia primarily affects individuals who have blood descendants of those African areas: achieving approximately 10% African-American descent carry this trait, and approximately one out of every 375 African American children born with this disease. Figure 12.4 shows the diagram of the chi square test genetic inheritance of sickle cell anemia.
