Hematopoietic radiation syndrome in the Gottingen minipig.

Additional large animal models for the acute radiation syndrome (ARS) would facilitate countermeasure development. We demonstrate here that Gottingen minipigs develop hematopoietic ARS symptoms similar to those observed in canines, non-human primates (NHPs) and humans. Dosimetry for whole-body γ irradiation (0.

Vascular access port implantation and serial blood sampling in a Gottingen minipig (Sus scrofa domestica) model of acute radiation injury.

Threats of nuclear and other radiologic exposures have been increasing, but no countermeasure for acute radiation syndrome has been approved by regulatory authorities. Because of their similarity to humans in regard to physiology and anatomy, we are characterizing Gottingen minipigs as a model to aid the development of radiation countermeasures. Irradiated minipigs exhibit immunosuppression, severe thrombocytopenia, vascular leakage, and acute inflammation.

Evaluation of hydration and nutritional gels as supportive care after total-body irradiation in mice (Mus musculus).

Concern regarding the potential for radiation exposure from accidents or nuclear and radiologic terrorism is increasing. The purpose of this study was to determine whether the addition of minimal supportive care consisting of hydration or nutritional gels could be used to reduce mortality in mice exposed to (60)Co gamma-radiation. Male CD2F1 mice received 0, 8.
