Brief Summary:
Seventy-two pregnant patients diagnosed of minor or intermediate beta thalassemia with mild anemia were randomly assigned to treatment group and control group. Patients in the treatment group were given 15 g of Colla corii asini in powder form daily for 4 weeks while the control group were observed and followed up in the same period without any treatments. Levels of hemoglobin(Hb), serum iron (SI), serum ferritin (SF) and three types of hemoglobin components [adult hemoglobin (HbA), fetal hemoglobin (HbF), minor adult hemoglobin (HbA2)] were measured before and after treatments.
