Body Fluids and Circulation Question 90
90. Examination of blood of a person suspected of having anaemia, shows large, immature, nucleated erythrocytes without haemoglobin. Supplementing his diet with which of the following, is likely to alleviate his symptoms?

(d) Thiamine
Show Answer
Answer : a
Hints & Solutions
(a) Folic acid (Cyanocobalamine-Vit. $B _{12}$ ) works in the formation and maturation of RBCs. In its deficiency RBC formation decreases and the formed RBCs will not mature i.e. they will not loose the nucleus and hence remain nucleated and lack haemoglobin. Such RBCs cannot carry oxygen & person suffers from anaemia. Supplementing his diet with folic acid and cobalamine will lead to the increased formation and proper maturation of enucleated RBCs with haemoglobin and eliminate anaemia.
