就113例边缘性龈炎的临床、组织学、组织化学(磷酸盐酶、β-葡糖醛酸酶、非特殊的酯酶)与T淋巴细胞的免疫组织化学所见进行了比较观察:(1)牙周袋渗出液的白细胞随牙龈炎指数的增加而增多;(2)牙周袋加深,游出的白细胞增多时,类圆形的脱落上皮细胞也增多;(3)经刷牙清洁,炎症消退者,牙周袋渗出液的白细胞和类圆形脱落细胞也减少;(4)牙周袋壁的渗出性炎症加重时,游到袋内的白细胞也增多; The clinical, histological, histochemical (phosphatase, beta-glucuronidase, non-specific esterase) and T lymphocyte immunohistochemistry findings of 113 patients with marginal gingivitis were compared ( 1) leukocytes in the periodontal pocket exudate increased with the increase of gingivitis index; (2) when the periodontal pocket deepened and the amount of leukocytes swimming out increased, the round shedding epithelial cells also increased; (3) , Inflammation subsided, periodontal pocket exudate leukocytes and round-like exfoliative cells also decreased; (4) exudative periodontal pocket wall exudate inflammation, the number of leukocytes swimming into the bag also increased;
