The normochromic cells have a normal concentration of haemoglobin, and are therefore 'red enough' while the hypochromic cells do not; thus the value of the mean corpuscular hemoglobin concentration.The most common cause of microcytosis is iron deficiency anemia. Every time Hb synthesis being impaired in bone marrow microcytosis can occurs such ...
Microcytic anaemia; Microcytosis is the presence of red cells that are smaller than normal. Normal adult red cell has a diameter of 7.2 µm. Microcytes are common seen in with hypochromia in iron-deficiency anaemia, thalassaemia trait, congenital sideroblastic anaemia and sometimes in anaemia of chronic diseases.

Pinocytosis, also known as cell drinking, is the absorption of small aqueous particles along with the membrane receptors that recognize them.It is an example of fluid phase endocytosis and is usually a continuous process within the cell.
Autoimmune disease.; Thymoma. [2]Viral infections such as HIV, herpes, parvovirus B19 (Fifth disease), [3] or hepatitis. [citation needed]Lymphoproliferative.Association of pure red cell aplasia with T-cell large granular lymphocyte leukemia is well recognized, especially in China.
The experimental drug TGN1412—also known as Theralizumab—caused extremely serious symptoms when given to six participants in a Phase I trial. [2] A controlled and limited CRS is triggered by active fever therapy with mixed bacterial vaccines (MBV) according to Coley ; it is used for oncological and certain chronic diseases. [ 19 ]
While virtually any drug should be considered as a possible cause of these signs and symptoms, the following drugs and drug classes are some of the most frequently reported causes: penicillins, cephalosporins, dapsone, sulfonamides, carbamazepine, phenytoin, lamotrigine, valproic acid, nevirapine, efavirenz, and ibuprofen. These drugs may cause ...
