    Notes: [Auszug] Polycrystalline d,Z-methionine ('De-gussa5, Frankfurt/Main) with a bulk volume of 187 cm8/100 g was evacuated (〈 10-3 torr) in quartz-tubes and X-irradiated (180 kV, 20 m.amp, half-value layer: 0-90 mm copper, dose-rate: 450 r/min, dose: 100 kr.). Nearly 5 min later, after the electron spin ...

    Notes: [Auszug] Polycrystalline native bovine serum albumin (Behring Werke, Marburg, Germany) with a bulk volume of 540 cm8/ 100 g was sealed under vacuum (〈 103 torr) and irradiated at room temperature. The electron spin resonance measurements were carried out under the same conditions. The irradiation with ...

    Radioprotective and haemopoietic effects of some lipopolysaccharides from Rhodospirillaceae species in mice (1981)
    Springer
    Cellular and molecular life sciences 37 (1981), S. 1331-1332

    Notes: Summary Lipopolysaccharides (LPS) from variousRhodopseudomonas andRhodospirillum species were tested for their radioprotective efficiency against X-irradiation and for their influence on the growth of spleen colony forming units (CFU-s) in mice. The LPS fromRhodopseudomonas gelatinosa Dr2 gave a high survival rate. It also favoured CFU-s formation and erythroid differentiation.

    Haematological studies on90Sr-90Y-toxicity (1980)

    Notes: Summary Erythropoietic changes were observed, measured by59Fe-uptake into red blood cells, and on radioiron turnover from blood plasma, at different time intervals (2–64 days) after treating adult female mice with varying activities of90Sr-90Y. Activities of 2.5 or 5.0 µCi radiostrontium per animal lead to a depression at time intervals of two and four days, at longer periods there was an overshoot. With activities of 0.5 or 1.0 µCi radiostrontium disturbances in the radioiron uptake are still observed, although these effects are not as pronounced as in experiments with higher burdens. In comparison with results obtained in experiments in which the plasma59Fe-turnover was applied, even with an activity of 5 µCi radiostrontium per mouse, no deviation as against the untreated controls was detected.

    Haematological studies on90Sr-90Y-toxicity: II. Femoral CFU-s kinetics and mitogen response of spleen cells (1982)

    Notes: Summary Ferrokinetic perturbances in peripheral blood of mice treated with90Sr-90Y were demonstrated previously. This paper deals with the effects of90Sr-90Y treatment (2.5, 5, and 10 µCi/mouse), on the haemopoietic stem cell compartment and on the immune-status. The frequency and kinetics of haemopoietic stem cells in femoral marrow (determined as colony forming units in spleen, CFU-s) and their haemopoietic efficiency (as gauged by59Fe-and125IUdR-uptake) were estimated. The responsiveness of splenic lymphocytes of the same animals to mitogens (Con A, PHA, and LPS) were also measured. In all assays striking dose-dependent changes marked either by depressions or overshoots were observed during the first week post-incorporation. These are correlated with the pattern of deposition (primary and secondary) of the radionuclides90Sr-90Y. Towards the end of the period of observation and presumably thereafter, the dependence on dose disappeared and the values remained subnormal. An exception to this was the response of splenic lymphocytes to mitogens. Much higher reactivity was recorded up to the end. This higher reactivity is attributed to augmented cellular turnover, the newly recruited lymphocytes (in accord with their extreme radiosensitivity), being probably more reactive.
