Abstract
GRAM-NEGATIVE endotoxins1 or typhoid-paratyphoid A and B vaccine (TAB)2 can have a favourable influence on the acute radiation syndrome when they are administered after total-body irradiation. By stimulating excessively the release of adrenergic neurohormones5,6 or by increasing sensitivity to catecholamines7,8, however, these substances can cause reduced blood flow to the kidneys, liver and intestines5 leading to ischaemia and irreversible tissue damage. Such changes may result from the vasoconstrictor action of catecholamines.
