Steady-state radiolysis of 2-, 3-, and 4-chlorobenzonitriles under various experimental conditions and HPLC-analysis of the resulting major products were performed. The initial G-values (G i ) of the products have been determined. Hydrated electrons

K562 erythroleukaemic cells produced ascorbate when incubated with dehydroascorbic acid. The reduction depended on the number of cells and on the concentration of dehydroascorbic acid. The observed rate consists of a high affinity (apparent Km 7 mu M

Hematoporphyrin dihydrochloride (HpDC) has been irradiated by red light (at λ=560 ± 20 nm) either in binary solvent mixtures modeling a lipid-like environment of dielectric constant 4–7 or in polar solvents. Quantum yields of the photochemical de

The radiation-induced formation of some haematoporphyrin (HP) transients in aqueous solution was studied by pulse radiolysis. The OH radicals attack HP (rate constant k = (1.3 +/- 0.2) x 10(10) dm3 mol-1 s-1) and the resulting transients decay with 2

The effect of the vitamins C, E-acetate and beta-carotene on the sanazole (AK-2123) efficiency was investigated in vitro (E. coli bacteria AB 1157) under the influence of gamma-rays. The vitamins were applied with sanazole individually or in appropri
