    Involvement of actin-containing microfilaments in HSV-induced cytopathology and the influence of inhibitors of glycosylation (1986)

    Notes: Summary Two and a half hours after infection with a high dose of different strains of HSV-1 which induce rounding of cells, breakdown of actin containing microfilaments can be observed. At the periphery of the cell, actin containing knob-like protuberances were visible. Later on, actin seems to be located exclusively on the surface of cells. Observations were done by immunofluorescence microscopy, scanning electron-microscopy and immunoperoxidase staining of ultrathin sections. The envelope of HSV appears to be stained by anti-actin. Strain IES produces rounding of cells at a high dose of infection before fusion proceeds at 37°C. Similar alterations were not observed with the fusing strains MP and HFEM. Incubation of infected cells at 39°C revealed strain dependent differences of the fusion activity. At 41°C no “fusion from within” of cells but only rounding was detectable. Application of tunicamycin resulted in complete inhibition of fusion by all strains. The fusion activity of some strains of HSV-1 (ANG, HFEM, and MP) was not inhibited by addition of 2-deoxy-D-glucose and 2-fluoro-deoxy-D-glucose. A variant from strain MP could be isolated, which is sensitive to the effects of 2-deoxy-D-glucose. Inhibitors of processing of glycoproteins did not affect fusion of cells.

    Notes: Abstract Long-term experiments have been undertaken to investigate the effects of various types of phosphorus fertilizers on yields, phosphorus uptake and fertilizer conversion in the soil. Optimum effects were obtained from water-soluble phosphate, whereas finely ground soft rock phosphate had little effect even with large amounts of phosphorus fertilizers and with a pH value of the soil of around 5.4. Partially decomposed and sintered phosphates performed well, as did NPK fertilizers (100% water soluble) and Thomas phosphate. The addition of large amounts of phosphorus fertilizers (to cereals, 26.4 kg/ha, to other crops 44 kg/ha) led to yields being increased by 7% and phosphorus extraction being increased by 11%. Smaller amounts of phosphorus fertilizers (13.2 and 17.6 kg/ha) did not have this effect. Increases in the amount of double-lactate-soluble phosphorus in the soil depended on the level of fertilization and did not differ significantly according to the type of phosphorus fertilizer used.
