Table 3 The comparison of frequencies of apoptotic cells and mitotic figures in colon biopsies.

From: Colon biopsies for evaluation of acute graft-versus-host disease (A-GVHD) in allogeneic bone marrow transplant patients

    Negative controls
   Group A Group B Group C
Number of apoptotic cells (per 10 HPF, X40, FD- 0.35 mm). Mean 5.29* 1.25* 1.42*
  Range 1 to 50 0 to 3 1 to 3
  SD 8.49 0.90 0.60
Number of mitotic figures in crypt lining (per 10 crypts). Mean 2.65 1.88 2.28
  Range 1 to 10 1 to 5 1 to 7
  SD 1.98 1.01 1.80
  1. SD, standard deviation; HPF, high power field, FD, field diameter. *Statistically significant differences between Group A / B and Group A / C respectively. The p values calculated by Wilcoxan Rank Sum Test were less than 0.002.
