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

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

			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

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.
