Figure 4

A: PAS staining of submandibular gland tissue from each group. Arrows indicate functional acinar cells. B: Surface area occupied by acinar 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.
