    Notizen: Summary A 73-year-old woman was diagnosed with seropositive destructive rheumatoid arthritis in 1981. She was treated with cortisone, chloroquine, and cyclophosphamide (Sendoxan) in 1982 and 1984 and contracted severe neutropenia. After that she only received cortisone. During 1991, again low neutrophilic counts were registered, especially granulocytopenia. At first, B-cell lymphoma was suspected, but later Felty's syndrome was established. The patient was treated with high-dose cortisone with some success and had a few minor septic episodes. In May 1992 she contracted a traumatic wound on the back of the lower leg. Conservative treatment resulted in a worsening of the condition and an increased wound area, most likely related to the neutropenic condition. In mid July the patient was hospitalized. Bacterial isolates yielded mixed gramnegative enteric bacteria from the wound. Parenteral antibiotic treatment was started, followed by oral drugs. rhG-CSF (filgrastim) was given subcutaneously once a day, starting 3 days after admission. This resulted in increased numbers of peripheral granulocytes. The ulcer started to heal and by mid August the patient received a transplant with autologous skin grafting. In mid September the wound was completely healed. It is concluded that the combination of antibiotics, skin transplantion, and G-CSF was necessary for the successful result. Actually, the bacterial growth did not call for antibiotics, but it was considered necessary to cover for staphylococci. No worsening of the underlying arthritis was observed.

    Notizen: Abstract It is controversial whether odontocetes (toothed whales) and mysticetes (whalebone whales) have a common ancestry. Cetacean karyological uniformity, which is unique among mammalian orders, suggests a monophyletic origin; however, several anatomical authorities have maintained that odontocetes and mysticetes are diphyletic. We investigated the issue using Southern blot hybridization. Two labelled restriction fragment probes from the DNA of the sei whale (a mysticete) were hybridized to restricted DNA of cetacean species representing all extant families except the Eschrichtiidae, the gray whales. The probes hybridized to specific restriction fragments in all odontocete and mysticete materials. Hybridizations showed preservation of hybridization homologies and a striking conservation of the length of highly repeated DNA sequences. The results are compatible with a common ancestry of odontocetes and mysticetes.

    Notizen: Abstract Normal mouse fibroblasts at early passage levels were used as a starting material to construct mouse-hamster microcell hybrids (MCH). Theneo r gene, carried on the pSV2neo and pZIP-NeoSV(X)1 plasmids, was introduced into the mouse fibroblasts by gene transfection and retroviral infection, respectively, prior to microcell hybridization into the E36 Chinese hamster cell line. In total about 180 MCH clones were isolated and their amount of mouse DNA was estimated by dot-blot analysis. About 50% of the transfection based hybrids (T-hybrids) showed signals indicating one mouse chromosome, less than 10% more than one mouse chromosome, and the remaining clones contained only subchromosomal amounts of mouse DNA. In the infection-based hybrid series (I-hybrids) more than 95% showed only subchromosomal mouse DNA content. Chromosomal integration analysis verified the presence ofneo r insertions in all 42 hybrid clones analyzed. C-banding analysis verified 14 of 15 hybrids scored as monochromosomals on dot blots. Chromosome fragmentation in T-type MCH was found to be (1) nonrandom, preferentially occurring in MCH derived from certain transfectants, (2) late in clonal establishment, and (3) essentially not related to prolonged cultivation in vitro. Once established, most T-type MCH clones including mono- and subchromosomal hybrids were essentially stable during prolonged cultivation. In contrast MCH initially containing several mouse chromosomes tend to lose the nonselectable ones during prolonged cultivation. In total we estimate the number of independent monochromosomal MCH derived in this study to more than 30.

    Notizen: Abstract A panel of four microcell hybrids representing different sites of insertion of the exogeneous neogene into mouse chromosome 17 has been constructed. These constructions were based on a cotransfer of mouse chromosome 17 and neomycin resistance generated in a stepwise procedure involving (1) random insertion of the neogene into a primary cell hybrid containing mouse chromosome 17 in a hamster cell background, (2) microcell-mediated chromosome transfer (MMCT) to segregate mouse and hamster chromosomes, and (3) identification of the mouse chromosome containing cells using a novel cell dotting procedure for mass screening at the cell colony level by molecular hybridization. Using this panel of four microcell hybrids for chromosome mediated gene transfer (CMGT), we obtained one transformant containing a chromosome fragment derived from the t-complex region located on mouse chromosome 17. It is concluded that the specific chromosome based procedure used here to generate CMGT transfectants may provide a general means to produce large numbers of transfectants containing megabase fragments covering, in principle, all regions of a given chromosome.
