[Serum tuftsin concentration as an indicator of postoperative splenic function after spleen-preserving surgery].

Serum tuftsin level was measured by reverse-phase high performance liquid chromatography in 40 cases. Compared with 10 normal controls, tuftsin level remained almost unchanged in 20 autotransplantation cases after splenic resection for traumatic rupture of the spleen, and in 10 partially splenectomy cases for splenomegaly hypersplenism. The level of tuftsin was lower than that of the normal controls though it was higher than that of total splenectomy cases.
