A: Immunohistochemical staining of CD₃₁ in different groups. Images of lower panel represent the higher magnification of the boxed area in corresponding images of upper panel. B: Surface area occupied by CD₃₁ ⁺ cells (% per gland) between different groups. Sham1: Pre-sterilized water group; sham2: Pre+Post sterilized water group; sham3: Post-sterilized water group. Data is presented as means ± SEM. *: P<0.05 compared with normal group; **: P<0.05 between two individual groups.
