SPE-like radiation and hindlimb suspension induces the accumulation of LPS in subepithelial regions of the ileum.

<p>Terminal ileum obtained 4 days post irradiation and/or 6 days post hindlimb suspension or from control animals was stained for LPS using a mouse mAb specific for E. coli LPS. A) Ileum from a control treated mouse. B) Ileum from a mouse irradiated with 2 Gy of 70 MeV protons. C) Ileum from a mouse subjected to hindlimb suspension. D) Ileum from a mouse treated with hindlimb suspension and irradiated with 2 Gy of protons. Original magnifications 200×. Tissue from 10 animals was analyzed for each condition.
