100 IU/L (2.5 x UNL)
8. Serum Hgb ≥ 10 gm/dl, platelet count ≥ 100,000/ul, total WBC count >= 4,000/uL,
absolute neutrophil count ≥ 1,500/ul
9. Patients must sign an informed consent indicating that they are aware of the
investigational nature of the study in keeping with the policy of the hospital. The
