Sickle cell anaemia. Coloured scanning electron micrograph (SEM) of red blood cells in sickle cell anaemia (drepanocytosis). Here,normally rounded red blood cells have become curved,elongated sickle-shaped cells. Sickle cell anaemia is an inherited blood disease largely affecting black people,in which the red blood cells contain abnormal haemoglobin,the oxygen-carrying pigment. In areas of deoxygenated blood the haemoglobin distorts the red blood cells into a sickle shape,causing bone ache and organ damage. The fragile sickle cells are easily destroyed in the bloodstream. No cure is yet known for this disease. Magnification unknown | |
