;
The effects of shielding the head or abdomen on functional state of the GI (gastrointestinal) tract during the first 3 days after exposure to ..gamma..-radiation were studied in experiments on albino rats. Local shielding of the head or abdomen lowered equally the degree of functional gastric disorders at the early (up to 24 h) postradiation stage. Thereafter, the protective effect of shielding the head diminished, whereas shielding of the abdomen, on the contrary, enhanced normalization of impaired GI functions. An evaluation was made of the contribution of central and peripheral mechanisms to early disturbances of radiation-induced GI functions.
