ABSTRACT
A 4-year-old boy with Diamond-Blackfan anemia and a history of multiple transfusions underwent umbilical cord blood transplantation from his HLA-identical female sibling born by vaginal delivery at 38 weeks. The patient was prepared with busulfan, cyclophosphamide and antilymphocyte globulin. Methotrexate and cyclosporin A were given for the prophylaxis of GVHD. Regimen-related toxicity was not observed and successful engraftment occurred, including the erythroid series. No evidence of acute or chronic GVHD has been observed for 14 months after transplantation. This is the first case of successful umbilical cord blood transplantation to a patient with Diamond-Blackfan anemia.

The teratogenicity of Tween 60 was studied in Wistar rats. Pregnant rats were given Tween 60 at a dose of 0, 0.1, 1.0 or 10% in the diet from day 7 to day 14 of pregnancy. Daily intakes of Tween 60 were 99 mg/kg for the 0.1% group, 960 mg/kg for the 1.0% group and 7693 mg/kg for the 10% group. No change induced by Tween 60 was detected in the number, sex ratio and body weight of live fetuses. External, skeletal and internal examinations of the fetuses revealed no evidence of teratogenesis. It could be concluded that Tween 60 has no harmful effects on the prenatal development of the rat offspring at doses employed in the present study.
