    Notes: Summary We have studied a family in which the mother and her son were carriers of an X;Y translocation, der(X)t(X;Y) (p22.3;q11). The mother was of slightly short stature and had mildly short upper extremities. The son had epiphyseal punctate calcifications, mildly short extremities, a flattened nasal bridge, and mental retardation (chondrodysplasia punctata). The extra bands on the short arm of the X chromosome were identified as deriving from the long arm of the Y chromosome, using in situ hybridization with a Y-chromosome-specific DNA probe (pHY10). The chondrodysplasia punctata seen in our case may be associated with the abnormality of the distal short arm of the X chromosome caused by X;Y translocation.

    Notes: Abstract Nongerminomatous germ-cell tumor (NGGCT) in the central nervous system (CNS) is still highly lethal. The present study evaluated the outcome of high-dose chemotherapy followed by autologous stem-cell rescue (ASCR). The patients included three cases of choriocarcinoma, two cases of embryonal carcinoma and one case of yolk sac carcinoma. High-dose cisplatin (200 mg/m2), etoposide (1250 mg/m2) and ACNU (150 mg/m2) were administrated in combination with ASCR to patients at complete remission as a result of surgical removal, irradiation, and from four to seven courses of induction chemotherapy. All the patients treated with this therapy were alive from one to seven years after the diagnosis, living with good performance status. The patients have not required any additional treatments after ASCR. The myelosuppression period, characterized by fewer than 500/µl peripheral neutrophils, ranged from 8 to 15 days (median, 11.5 days). Within seven days of ASCR, high fever was found in four patients. Although mild liver dysfunction was found in all patients, renal dysfunction was not observed. Hearing disturbance was found in 50% of the patients. This treatment regime will improve long-term survival for patients with NGGCT.

    Notes: We studied the effects of murine recombinant granulocyte-macrophage colony-stimulating factor (GM-CSF) on murine hemopoiesis in methylcellulose culture. The GM-CSF was purified from cultures of Saccharomyces cerevisiae transfected with a cloned murine GM-CSF cDNA. In cultures of spleen cells from normal mice, only granulocyte-macrophage (GM) colonies were supported by GM-CSF. Blast cell colonies were the predominant type in cultures of spleen cells from 5-fluorouracil (5-FU)-treated mice. Dose-response studies revealed that maximal GM and blast cell colony formation is achieved with 100 U/ml GM-CSF. Blast cell colonies revealed variable but high replating efficiencies, and the secondary colonies included multilineage colonies. Serial replating of washed blast cell colonies in cultures with GM-CSF provided evidence for the direct effects of GM-CSF on the proliferation of multipotential blast cells. A combination of GM-CSF and interleukin-3 (IL-3) did not increase the number of blast cell colonies over the level supported by IL-3. This observation indicates that the progenitors for blast cell colonies that responded to GM-CSF are a subpopulation of multipotential progenitors that are supported by IL-3. Cytological studies of colonies derived from GM-CSF and/or IL-3 suggest that the eosinophilopoietic ability of murine GM-CSF is less than that of IL-3.

    Notes: We investigated the effects of interferon γ (IFN-γ) on the growth of murine hematopoietic progenitors. IFN-γ inhibited granulocyte colony-stimulating factor (G-CSF)- and interleukin-3 (IL-3)-dependent colony growth by granulocyte-macrophage (GM) progenitors derived from the bone marrow cells of normal mice. However, the number of IL-3-dependent GM colonies formed by the bone marrow cells of 5-fluorouracil (5-FU)-treated mice was not influenced by the addition of IFN-γ. Replating experiments suggested that IFN-γ suppressed GM colony growth directly and that it exerted an inhibitory effect on the proliferation, but not on the commitment, of GM progenitors. In contrast, IFN-γ failed to suppress colony growth by mast cell progenitors. Erythroid and megakaryocytic progenitors exhibited different responses to IFN-γ depending on mouse strains. These results suggest that potent negative regulators are not always inhibitors of hematopoietic progenitors. © 1992 Wiley-Liss, Inc.
