We performed immunohistochemical and histopathological investigation on the inflamed gingiva from the patient with Yusho and on the periodontal tissue from PCB poisoned rats respectively. The results obtained were as follows. 1) In the gingiva from the Yusho patients, the proportions of plasma cells, B cells, T cells in the inflammatory cells and CD4/CD8 ratio were 47.9%, 18.3%, 10.7%, and 2.84, respectively. 2) In the periodontal tissue from rats with experimental periodontitis, we found no definitive difference between the PCB poisoned rats and the clinically healthy rats.

We have studied immunocytochemically the distribution of CGRP-containing nerve fibers in the PCB poisoned rats introducing experimental periodontitis. The results obtained were as follows. In the PCB poisoned rats, some specimens obtained from periodontitis-affected sites showed a slight increase in both the intensity of nerve staining and the nerve sprouting. However, no discernible difference in the occurrence and the distribution of nerves has been demonstrated between the PCB poisoned rats and clinically healthy rats. Further studies are needed to confirm the effects of PCBs on the initiation and progression of periodontitis.
