Neutrophils in Beagle dogs in different groups.

<p>Note: Data are mean +/− standard deviation. The numbers are ×10⁹/L.</p><p>*: compared with model control, P<0.05;</p>#<p>: compared with positive control, P<0.05. D1-D27 are the days of the experiment. After D3, NEUT of all irradiated dogs were significantly lower than normal control, <i>P</i><0.05. Duration of neutropenia is defined as the days of absolute neutrophil count (ANC) is lower than 2×10⁹/L. Nadir (x10⁹/L) mean the lowest Neutrophils. The recovery level (%) mean the ratio of the Neutrophils on D27 to preradiation.
