abstract：:Synthetic lysophospholipids represent a variety of analogs of the naturally occurring 2-lysophosphatidylcholine. Some of these compounds showed significant therapeutic effects on the survival of mice following radiation injury when administered after various doses of whole-body X irradiation. Such therapeutic effects ...

abstract：:The anoxic sensitization of bacterial spores by added H2O2 has been studied. Two mechanistic pathways for damage from H2O2 were found; one of these requires the presence of OH radicals. For this kind of damage, the relationship between H2O2 and OH appears to be that they are reactants. O-2 (and/or HO2), the product of...

abstract：:The percentage of T lymphocytes of atomic bomb survivors showed no change as a function of age or exposure dose. The percentage of T cells was slightly lower in malignant-tumor patients than in the control group, but was significantly higher in the group with chromosomal aberrations than in the control group. The perc...

abstract：:An induction-type radiofrequency generator was used to heat thigh implants of the VX2 rabbit carcinoma. The tumor temperature could be easily raised to over 50 degrees C, while the temperature of normal adjacent muscle generally remained at about 43 degrees C. The marked hypovascularity of the tumor, as demonstrated a...

abstract：:Pulse radiolysis and 60Co gamma radiolysis were used to study the effects of ionizing radiations on the activity of glutamate dehydrogenase. Hydroxyl radicals are considerably more effective than hydrated electrons in causing loss of enzymatic activity. Evidence is also presented that the free radical anions (SCN)-.2,...
