Figure 1.

Pulsed Low Dose Rate Radiotherapy (PLDR) is associated with reduced levels of bone marrow and intestinal atrophy at equivalent doses of Conventional Radiotherapy (CRT). H/E staining shows cellular atrophy in the bone marrow (BM) (A) and the cecum (B) following treatment with CRT and PLDR. Morphometric quantitation using the NIH Image J software of atrophic areas in the BM, pancreas and intestine is shown (C). The arithmetic mean of a minimum of 5 analyzed tissue areas from 1–2 mice is shown. Error bars represent the standard error. BM, bone marrow.
