Abstract
Enprostil, a synthetic E2 prostaglandin, was administered in a dose of 5 micrograms/kg body weight by gastric tube to rats for 14 days following abdominal irradiation with a single dose of 600 cGy from a 137Cs source. Enprostil prevented the body weight loss and the reduced food intake observed in irradiated animals given placebo, and also prevented the irradiation-associated decline in the mucosal weight and surface area of the ileum. Enprostil given to nonirradiated animals reduced the maximal transport rate (Vmax) and the apparent Michaelis constant (Km*) for the ileal uptake of D-glucose, but did not prevent the irradiation-associated decline in the ileal uptake of glucose. Thus, there is a dissociation of the effects of Enprostil on the morphological and the absorptive properties of the intestine. It is concluded that a 2-week course of a daily oral dose of E2 prostaglandin begun shortly after a single exposure to nonlethal abdominal irradiation prevents the radiation-associated reduction in the intestinal mucosal surface area and the animal's body weight, but does not prevent the malabsorption of glucose.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
