Ranges of lactulose and mannitol in the urine of control and exposed mice fed either methionine-adequate or methionine-supplemented diets.

Lactulose and Mannitol Urine Concentrations by Diet, Radiation, and Time after Radiation
Diet	Radiation	Days after Radiation	Lactulose (μmol/mL)	Mannitol (μmol/mL)
Adequate Methionine	Sham	7	0.135–0.217	12.3–19.8
Adequate Methionine	Sham	10	0.103–0.192	11.4–20.4
Adequate Methionine	Local Abdominal	7	0.151–0.294	16.2–28.6
Adequate Methionine	Local Abdominal	10	0.183–0.327	16.1–27.5
Supplemented Methionine	Sham	7	0.181–0.267	12.8–25.3
Supplemented Methionine	Sham	10	0.158–0.279	14.8–27.9
Supplemented Methionine	Local Abdominal	7	0.245–0.396	18.5–31.4
Supplemented Methionine	Local Abdominal	10	0.226–0.344	20.5–30.5

Local abdominal radiation was performed with the Small Animal Radiation Research Platform. Mice were exposed to 12.5 Gy in a one cm transverse section just below the last rib and just ventral to the spine. Values given are ranges (n = 6 per diet, radiation, and days after radiation).
