[Treatment of Giant Cell Tumor of Bone in the Distal Radius and Ulna].

PURPOSE OF THE STUDY The preferred treatment of giant cell tumor of bone is curettage with the use of local adjuvant. If the tumor spreads beyond the bone into soft tissues, en bloc excision should be performed. Intralesional curettage allows joint preservation, but it is associated with a high recurrence rate.

Acidified chloroquine treatment for the removal of class I HLA antigens.

With the aim of reducing the damage to platelets while effectively removing class I HLA antigens from their surfaces, we developed a new method using acidified chloroquine diphosphate. Platelets were treated with a 0.2 M solution of chloroquine diphosphate (pH 4.

Thirty-five-day modified red cells and 7-day stored platelet concentrates from triple bags of identical PVC formulation.

There is continuous need for blood components with long shelf life. To this end the 'circle' triple pack has been modified to provide 35-day red cell and 7-day platelet concentrates, in PVC bags of identical formulation and 0.4 mm thick.
