Treatmentof cells in primary culture with 30 M hydroxyurea for 96 hours significantly increases the fractional

7、 HbF content. TheG: A-globin mRNA is induced 0.30- to 8-fold in vitro2. Hydroxyurea has been shown to block HIV-1 reversetranscription and/or replication in quiescent peripheral blood mononuclear cells and macrophages3.體內(nèi)研究 Hydroxyurea therapy producs consistent reductions in WBC and ANC without imp

8、rovement in anemia over 17 weeks.Hydroxyurea at 50mg/kg produces a reduced white blood cell count, absolute neutrophil count and no improvementin anemia compared to vehicle treated sickle cell mice4.PROTOCOLAnimal Mice: To determine whether hydroxyurea would improve anemia and/or prevent or diminish

9、 the development ofAdministration 4 organ damage in the absence of HbF induction, hydroxyurea, at doses of 25 mg/kg, 50 mg/kg, and 100 mg/kg, orvehicle is administered five days per week to SCD mice4.MCE has not independently confirmed the accuracy of these methods.
