Summary. Three cases of acute leukaemia with t(4;12) (qll-12;pl3) karyotypic abnormalities were analysed. They had the following common clinical and biological characteristics: (1) dysplasia of three haemopoietic lineages; (2) absent or low myeloperoxidase activity; and (3) retention of platelets in the peripheral blood and megakaryocytes in the bone marrow. There were increased numbers of basophils in the bone marrow and peripheral blood in two of the cases. In all, the blast cells displayed the unique immunophenotype CD7+ CD13+ CD34+ HLA-DR+ . The blasts analysed in one case expressed c-kit on the membrane surface. These findings suggest that the t(4:12) (qll-12:pl3) abnormality is associated with a particular type of acute leukaemia, one in which the morphology and immunophenotype suggest that the translocation may have occurred at an early stage of haemopoiesis. 相似文献

A prospective study was performed to investigate the validity of renal failure index (RFI) or fractional excretion of sodium (FENa) in preterm infants. The subjects were 128 newborn infants, 72 with oliguria and 56 without renal dysfunction (control). Oliguric infants were divided into two categories: acute renal failure (ARF) and prerenal failure (PRF), according to creatinine clearance (Ccr). Furthermore, all subjects were divided into four groups according to gestation, that is, 38 infants with gestational age of 25–28 weeks (group 1), 28 with 29–30 weeks (group 2), 38 with 31–36 weeks (group 3) and 24 of > 37 weeks (group 4). As a result, differentiation between ARF and PRF was valid when the RFI or FENa was used in infants of > 29 weeks gestation (groups 2, 3 and 4). Although infants of > 31 weeks gestation (groups 3 and 4) who present with an RFI > 3 or an FENa > 3% may be diagnosed as having ARF, infants in group 2 with an RFI of > 8 or an FENa of > 6% may be diagnosed as having ARF. For the infants in group 1, the application of RFI or FENa for diagnosis of ARF may be limited because of some overlap among the groups. 相似文献
