Thalassemia地中海贫血

Rationale

145. Correct answer: b.
Thalassemia minor is generally asymptomatic and does not require treatment. It is an inherited disorder which most often affects persons of Mediterranean descent. The disease is characterized by decreased production of RBCs and chronic hemolytic anemia.

146. Correct answer: d.
The hemoglobin S red blood cell, which has normal oxygen-carrying capacity, forms a sickle shape under conditions of decreased oxygen tension in the blood. The sickled cells tend to clump and block small blood vessels thereby causing tissue hypoxia. Sickle cell anemia is inherited as an autosomal recessive disorder which means a defective gene had to be inherited from both the mother and the father. Therefore, if a woman with sickle cell anemia has a child with a man who does not have the disease and is not a carrier; the child will be a carrier but will not have the disease itself. Splenectomy does not relieve the symptoms of sickle cell disease; it relieves the symptoms of hereditary spherocytosis.
