Immunohistochemical staining showing CD45RO+-expressing cells in uterine cervix tissues in IE and MS sites from (A) HC, (B) CIN I, (C) CIN II, (D) CIN III, and (E) CC. Original magnification = × 20, (F) represents the means ± SD of CD45RO expressing cell counts among the groups. ap < 0.05, HC versus CIN I; p < 0.001, HC versus CIN II, III and CC. bp < 0.01, HC versus CIN III. cp < 0.001, CC versus CIN I and HC; p < 0.01, CC versus CIN II. P value was calculated using the nonparametric Kruskal–Wallis test and post-test of Dunns for multiple comparisons.
