Objective To study the changes of serum MMP-9 concentration and WBC count in acute cerebral infarction patients.
8和细胞外弹性蛋白酶的浓度和总量在重度牙周炎组明显高于轻、中度牙周炎组（P<0.01）。
The concentration and total amount of EA-sand IL-8 in severity periodontitis patients were significantly higher than those in light, moderate samples(P<0.01).
骨性节炎软骨细胞直接分泌到胞外的金属蛋白酶含量变化不明显；
The variance of MMPs'content in ECM of OA chondrocytes of rabbits secretion was not significant.
结论：细胞外弹性蛋白酶浓度较IL - 8浓度更能够反映牙周袋内的炎症程度。
Conclusion: the concentration of EA-sis more accurate than the concentration of IL-8 for indicating the inflammation of periodontal pocket.
