| 摘 要： | 测定老年牙周炎患者外周血ＮＫ细胞活性。采用ＭＴＴ法测定，并与成年和青少年牙周炎患者进行比较。发现老年牙周炎患者外周血ＮＫ细胞活性低于成年牙周炎患者（Ｐ＜０．０１），也低于青少年牙周炎患者（Ｐ＜０．０５）。老年牙周炎患者ＮＫ细胞活性低下可能是老年人牙周病发病率高，组织破坏重的原因之一。

| Abstract: | To measure the activity of NK cells of venous blood in elderly patients with periodontits.The activity of NK cells of venous blood in 10 elderly patients with periodontitis was measured with MTT method and was compared with that in adult patients and in juveile patients.It was found that the activity of NK cells of venous blood in elderly patients was significantly lower than that in adult patients( P < 0.001 ) and in juveile patients( P <0.05).These data suggested that the low activity of NK cells of venous blood in elderly patients may be one of the major factors causing serious periodontitis in elderly patients. |
