An immunohistochemical study on the effect of aging on the distribution of natural killer cells in gingiva of patients with periodontitis
Abstract：AIM：To observe the distribution of NK ce lls in gingiva of elderly patients with periodontitis. METHODS: The localizations and numbers of NK cells, T lymphocytes and B lymphocytes in gin giva of 15 elderly patients with periodontitis were measured with immunohistoche mical method and were compared with those of 10 adult patients with periodontiti s. RESULTS: The number of NK cells in adult patients was s ignificantly greater than that in elderly patients(P<0.01)，and the cases of NK cells position in adult patients were more than that in elderly patients. [ WT5”HZ〗CONCLUSION: The function of immunological regulation in loca l gingiva of elderly patients with periodontitis is disorder, and the function o f NK cells is low.
