13. Effects of antioxidants on oxidant-induced sister chromatid exchange formation.
Stimulated human phagocytes produce sister chromatid exchanges in cultured mammalian cells by a mechanism involving oxygen metabolites. Experiments were designed to determine whether antioxidants inhibit this process. Superoxide dismutase, catalase, and hydroxyl radical scavengers (benzoate, mannitol) protected target Chinese hamster ovary cells from phagocy

14. Accumulation of α-Keto Acids as Essential Components in Cyanide Assimilation by Pseudomonas fluorescens NCIMB 11764
Pyruvate (Pyr) and α-ketoglutarate (αKg) accumulated when cells of Pseudomonas fluorescens NCIMB 11764 were cultivated on growth-limiting amounts of ammonia or cyanide and were shown to be responsible for the nonenzymatic removal of cyanide from culture fluids as previously reported (J.-L. Chen and D. A. Kunz, FEMS Microbiol. Lett. 156:61–67, 1997). The

15. Antiviral effect of lymphokine-activated killer cells: characterization of effector cells mediating prophylaxis.
Lymphokine-activated killer (LAK) cells generated by cultivation of C57BL/6 mouse spleen cells in the presence of recombinant interleukin-2 were transferred into natural killer (NK) cell-deficient suckling mouse recipients. These mice were then challenged with either murine cytomegalovirus (MCMV) or lymphocytic choriomeningitis (LCMV) and sacrificed 3 days l
