Change of lymphocyte count in Yucatan minipigs exposed to pSPE radiation or eSPE
radiation. A minimum of 3 animals per group were exposed to pSPE radiation (A)
at a single skin dose of 5 , 7.7 or 10 Gy or eSPE radiation (B) at a single skin
dose of 5, 7.5, 10, or 20 Gy. The lymphocyte count was determined at the
indicated time points. The results are expressed as fraction of control and
compared with the pre-irradiation baseline value (indicated by dashed line).
Statistical significance of the comparison is indicated by an x (p is between
0.005 and 0.10, and considered as marginally significant), * (p < 0.05),
** (p < 0.01) and *** (p < 0.001), as appropriate. Each data point
represents a mean of three animals, and the associated standard error is
indicated by the error bar.
