Effects of Polyvinylpyrrolidone on Whole-body-irradiated Rats
International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1964SummaryPolyvinylpyrrolidone (PVP) given intraperitoneally four times at 12-hour intervals reduced the mortality of rats exposed to whole-body irradiation by 650 r, but hastened post-irradiation death when the dose was 800 r. The granulocyte-rich ascitic fluid produced by the injection of PVP did not possess either protective or therapeutic qualities ...

Radioactivity: Effects of Whole Body Irradiation
Annual Review of Medicine, 1952Radiation through its biologic effects and its use as a tool in research is rapidly spreading in to all facets of science and medicine. Through the medium of the atomic bomb, radiation is extending into the fields of diplomacy, politics, and the social sciences.

Dopamine Protects Mice against Whole-Body Irradiation
Science, 1967Injection of dopamine before whole-body x-irradiation of mice resulted in 80 percent survivors whereas no irradiated controls survived; injection after exposure had no effect. D,L-Dihydroxyphenylalanine, the precursor of dopamine, had no effect on survival when injected either before or after irradiation.

Benzoyl-glycine Conjugation after Whole-body Irradiation
International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1968SummaryUrinary excretion of benzoyl-glycine was increased after whole-body gamma-irradiation of rats, sheep and pigs maintained on a constant daily food intake. The increase occurred in the rat and sheep in the third and fourth week, and in the pig in the third to sixth weeks.

Deoxycytidine in Urine of Humans after Whole-Body Irradiation
Science, 1963Increased levels of deoxycytidine were found in the urine of two humans during the first 24 hours after irradiation. This substance presumably was produced by the breakdown of DNA following irradiation, or resulted from interference with the synthesis of DNA.

The Effect of Heating on Susceptibility to Whole Body Irradiation in the Mouse
The British Journal of Radiology, 1964The effect of raising the environmental temperature to 37°C on the susceptibility of white Swiss mice to whole body irradiation has been studied and enhancement of effect demonstrated for all doses of irradiation in the range 300 R to 600 R. Enhancement was observed if heating preceded irradiation, but not if irradiation preceded heating.

PATTERNS OF HEMOPOIETIC RESPONSE TO CONTINUOUS WHOLE‐BODY IRRADIATION
Annals of the New York Academy of Sciences, 1964Massive splenic erythropoiesis developed in rats during continuous exposure to gamma radiation at a rate of 70 r per day. The erythropoiesis was first seen between the fifth and sixth week of irradiation. It was not accompanied by bone-marrow recovery.

Natural β-carotene and whole body irradiation in rats
Radiation and Environmental Biophysics, 1996beta-carotene and other carotenoids are reported to be potent free radical quenchers, singlet oxygen scavengers, and lipid antioxidants. Whole-body irradiation is known to cause an immunosuppression effect in mammals through the possible initiation and production of reactive oxygen species.

HEMATOLOGICAL RESPONSES TO INHOMOGENEOUS AND HOMOGENEOUS WHOLE‐BODY IRRADIATION*
Annals of the New York Academy of Sciences, 1964Effects of homogeneous radiation were compared to effects of inhomogeneous radiation in uremic patients irradiated in attempts to increase the receptivity of renal homografts. Homogeneous radiation was given by means of an 1800-C /sup 60/Co source, and inhomogeneous radiation from a 250-kv orthovoltage source.
