    Notes: Summary A 43-year-old man was treated with orchiectomy and radiotherapy for testicular seminoma. Four years later, he developed a typical Philadelphia chromosome positive chronic granulocytic leukemia. Since the patient was not eligible for bone marrow transplantation, he was treated with busulfan. Long term follow-up of patients who received radiotherapy for testicular seminoma is warranted in order to detect possible secondary tumors.

    Notes: Abstract We report the case of a 64 year old male patient with a history of ischemic heart disease who underwent surgery for an abdominal mass. The histological diagnosis was highly malignant non-Hodgkin's lymphoma. After surgery the patient was admitted to our Department and received 6 courses of chemotherapy according to the COP schedule, followed by radiotherapy to the left upper abdominal region and ipsilateral lung base. The patient achieved partial remission. One month later he began to complain of left axillary lymphadenomegaly, polydipsia and polyuria. A NMR brain scan showed a hypophyseal mass. The patient was treated with DDAVP and chemotherapy with the PRO-MACE protocol; the polyuria and lymphadenomegaly disappeared and the size of the hypophyseal mass reduced markedly. The clinical picture was, therefore, attributed to a hypophyseal localization of the non-Hodgkin's lymphoma, which is a very rare manifestation of lymphomatous spread to the central nervous system. Our case is also interesting because it shows that a favorable outcome can be obtained with chemotherapy, provided that the latter is sufficiently aggressive. This is not necessarily the case with radiotherapy which may also be followed by late and severe neurologic sequelae.

    Notes: Abstract Human pluripotential stem cells (PSC) are currently the target fortransplantation attempts and genetic manipu-lation. We have thereforeinvestigated the frequency and the expansion potential of PSC's in differenttypes of blood samples. CD 34+ cells were thus obtained from human bonemarrow (BM), as well as from peripheral blood (PB) and cord blood (CB)samples. After immuno-magnetic separation the highest yields of CD 34+cells were from BM (1.08-2.25%) and CB (0.42-1.32%) while PBsamples gave much lower values. Suspension cultures of PSC's from the threesources were then set up, in the presence of combinations of haemopoieticgrowth factors. A remarkable amplification of the nucleated cell pool wasobserved reaching a maximum between 10 and 15 days of culture; earliest andmaximum expansion (up to 220-fold) was achieved when Erythropoietin (Epo)was added to the culture medium, but this resulted in reduction ofcolony-forming cells and differentiation into erythroid progenitors.Clonogenic tests for BFU-E's derived colonies showed a peak value at 5 daysof liquid culture. Further studies are advisable to establish the bestcytokine combination for a valuable ex vivo expansion, coupled withpreservation of stem cell properties.
