    Notizen: For the first time, atomic force microscope measurements on the (111) and (100) surfaces of AgBr crystals are reported. We could image steps of varying sizes ranging from 0.9 nm to several nm. The lateral orientation of these steps could be determined by comparison with x-ray measurements. On the (100) surface, steps with the low index orientations 〈011¯〉 and 〈011〉 were observed. On the (111), surface steps were mainly oriented in the 〈12¯1〉 and 〈11¯0〉 directions. The most evident difference between these surfaces was that on the (111) surface no crossing steps occurred. This observation will be discussed in relation to the adsorption of dye aggregates on these crystals, which is of great importance for photographic emulsion technology.

    Notizen: We present high-resolution magnetic force microscopy (MFM) images of a Co80Cr20 film with a thickness of 230 nm. We clearly observe a stripe domain structure with a domain width of 220 nm, the highest resolution of a periodic magnetic structure measured by MFM to this date, by measuring forces as small as 0.1 nN. The micromagnetic structure is compared to the morphology of the sample, which consists of vertical columns with an average cross section of about 40×60 nm2. The average surface roughness of this film did not exceed 12 nm on a 1-μm lateral scale. A magnetic fine structure of typically 50 nm width and more than 200 nm length is observed. Theoretical calculations of force traces are in reasonable agreement with experiment. A nonuniform sample magnetization, correlated to the morphology, has to be assumed to simulate the observed fine structure of force traces. Calculated images characteristically depend on the effective domain structure of the last 500 nm of the tip.

    Notizen: Abstract. The eggs of 30 female chinook salmon, Oncorhynchus tshawvtscha (Walbaum), were collected at spawning. Some eggs from each fish were collected for bacteriologic study. Two salmon produced eggs judged to be of poor quality which were not used. The remaining 28 of the 30 groups of eggs were fertilized from a single sperm pool and the eggs incubated in separate groups. Mortality data on the developing salmon were recorded regularly through the twelfth week on feed. Unfertilized eggs from each group were surface-disinfected with an iodine solution, then crushed and subjected to a culture procedure designed to permit growth of as many bacterial types as possible. Bacteria were cultured and identified, and a comparison made of the types of organisms present in eggs from groups which later incurred high or low mortalities. Bacteria were recovered from both groups of salmon eggs. Although no single organism could be identified as a cause of increased mortality, the more frequent occurrence in the eggs of the ‘high mortality’ group of species of Vibrio, Listeria, Corynebacterium and Staphylococcus suggests that these bacteria may play a role. It is suggested that the cause of so-called early lifestage disease of salmon is multifactorial.

    Notizen: Summary 26 homosexual men with antibodies to HIV and generalized lymphadenopathy were examined between 1982 and 1984. Lymphadenopathy was accompanied by clinical symptoms such as fever, diarrhoea and weight loss (50%), moderate leukopenia (15%), lymphocytosis (50%), hypoergy to intraepidermal skin test with recall-antigens (12%), elevated serum levels of IgG (62%), IgA (23%), IgM (19%), beta-2-microglobulin (76%) and neopterin (69%), diminished absolute numbers of CD4-helper cells in the peripheral blood (24%) and an inversion of the ratio CD4-helper cells/CD8-suppressor cells both in blood (64%) and in lymphnodes (36%). Mitogen induced lymphocyte proliferation was significantly lower and the serum levels of gamma-interferon were significantly higher than in healthy controls. Lymphnode biopsy revealed only nonspecific reactive hyperplasia with follicular hyperplasia in 54%, a mixed pattern of both follicular hyperplasia and follicular involution with paracortical expansion in 25% and follicular involution with paracortical expansion in 21%. 22 patients were followed longitudinally for a median time of 37 months (33–51 months). 10 patients (46%) developed fullblown AIDS within a median period of 35 months (24–46 months) after first examination and 43 months (36–77 months) after the anamnestic onset of the lymphadenopathy syndrome. The parameters distinguishing these patients from those without progression of disease were higher serum levels of gamma-interferon, higher relative and absolute numbers of CD8-suppressor cells in the peripheral blood, a reduced number of CD4-helper cells in the lymphnodes, and a lower CD4/CD8 ratio as well in the peripheral blood as in the lymphnodes. Despite of the significant differences, these parameters varied in a wide range. Therefore, we could not establish a symptom likely to predict the emergence of AIDS in an individual patient.

    Notizen: Summary 26 homosexual men with HIV-infection and lymphadenopathy syndrome were examined between 1982 and 1984 and prospectivelly observed over a period of 58 months (median, range 53–69 months). 16 (61.5%) developed full blown AIDS within a median period of 41 months (23–63 months). 12 of them died 50 months (median, range 29–67 months) after the first examination. 10 patients showed no symptoms of AIDS after a median observation time of 57 months (54–63 months). A panel of clinical symptoms, signs of concomitant infections, chemical and immunological analyses, including a lymphnode biopsy were correlated to the course of the disease. A decreased proportion of CD4-cells and a lower CD4/CD8ratio in the lymphnode suspensions at the first examination in patients with disease progression were the only parameter which correlated significantly with the development of AIDS.
