A20) aplastic anemia, renal disease
Normochromic normocytic anemia is the condition in which the blood cells are in normal size and normal in shape and the anemia is present.
Aplastic anemia is the failure of bone marrow. It is the disorder due to attack of white blood cells on bone marrow. The cells is aplastic anemia is normal in size of RBC and normal shape cell.
Renal failure occurs in normochromic and normocytic anemia due to infiltration of RBC cells in glomerulus.
A21)Hereditary stomatocytosis
In Hereditary pyropoikilocytosis, spectrum deficiency is there.
In Hereditary spherocytosis, incorporation and binding spectrin takes place.
In Hereditary elliptocytosis, defect in two spectrins occurs. Alpha spectrin and Beta spectrin. Mutations in genes of alpha spectrin lead to incapability to form alpha beta heterodimers. And mutation in beta spectrin leads to incapability of formation of tetramers.
In Hereditary stomatocytosis, the spectrin molecules will not be defected. It occurs due to osmosis which leads to burst and rupture of cells.
A22)false
In hereditary stomatocytes, increased numbers of stomatocyte cells present in blood smears of alcoholics, liver failure patients etc.
A23)acanthocytes
A24)pancytopenia
A25) acanthocytes
