The same specimens as shown in Table 1. The counting was performed at the hot spot (a site with the highest density) in the section. Greater number (smaller number) for the oral mucosa, conjunctiva and penis: the greater number indicates total cell number per mm in the epithelium as well as in the submucosal or subcutaneous tissue within 0.1 mm from the epithelial base. The smaller number indicates cell numbers migrating into the epithelium. In the anus, CD8-positive lymphocytes were not seen in the epithelium. ND, a failure in the immunostainig or the other histological procedure. a)Fig. 3. b)Fig. 2. c)Fig. 5. d)Fig. 4. e)Fig. 1.
