    Notes: Summary To investigate the mechanism of Bacillus de Calmette Guérin (BCG) bladder instillation therapy, the killer cell activity induced in peripheral blood mononuclear cells (PBMNCs) after BCG instillation was examined. Significant cytotoxic activity against natural killer (NK) cell resistant target tumor cells was detected after 3 days of instillation. To characterize this BCG induced cytotoxic activity further, human PBMNCs were cultured with BCG in vitro. From 24 h maximum cytotoxicity was obtained and continued for 3 days, then decreased slightly. Neither a DNA synthesis inhibitor Cytosine-arabinoside (Ara-C) nor a cytotoxic T cell (CTL) generation inhibitor Cyclosporine A inhibited this killer cell activation. Monoclonal antibody treatment revealed that both precursor and effector cells are Leu1-, 3a-, 7+, 11b+. The recognition specificity from cold target competition experiments was selective. Taken together NK type precursor was activated with BCG into NK type effector which has wider spectrum of target cells than usual NK cell.

    Microneurographic analysis of muscle sympathetic nerve activity in amyotrophic lateral sclerosis (1993)
    Springer
    Clinical autonomic research 3 (1993), S. 131-135

    Notes: Abstract Muscle sympathetic nerve activity by (microneurograph) blood pressure and heart rate has been studied in patients with amyotrophic lateral sclerosis and in age-matched normal subjects (controls) at rest and during head-up tilt. Muscle sympathetic nerve activity in amyotrophic lateral sclerosis patients was significantly increased at rest unlike controls. There was no correlation between muscle sympathetic nerve activity and age in the patients with amyotrophic lateral sclerosis. Elevated muscle sympathetic nerve activity was present mainly in younger patients. There were no differences between blood pressure or heart rate in either group at rest or during head-up tilt in amyotrophic lateral sclerosis. The increase in muscle sympathetic nerve activity following tilt in the amyotrophic lateral sclerosis patients was less than in the controls, but they had no postural hypotension. The possible reasons for this observation of increased muscle sympathetic nerve activity at rest in amyotrophic lateral sclerosis are discussed.

    Ab-initio molecular dynamics simulation of monolayer C60 thin film on silicon (100) surface (1993)

    Notes: Abstract Two dimensional band structure is calculated for a triangular lattice of C60 molecules by using a mixed-basis approach in which wave functions are expanded with not only plane waves but also 1s and 2p atomic orbitals of carbon atoms. The present analysis modeling a charge transfer from Si dimers of the Si (100) surface suggests the existence of a small Fermi-surface. The resulting partial charge distribution is consistent with the recent STM observation of specific stripes, the direction of which is parallel to that of the topmost double bond of C60, regardless of the intermolecular interaction. It is concluded that the orientation of C60 on the Si surface is mainly determined by the direction of dimer arrays and not by the interaction between C60 molecules.
