砄bjective To observe NO level in gingival tissue of elderly patients with periodontitis. Methods: 4 mm 3 gingival tissue was obtained during tooth extraction and NO in the tissue of 14 patients aged 65～81 years with periodontitis was measured with nitrate reductase assay. The NO level was compared with that of 9 adult patients (40～58 years old), 6 juveniles patients (25～30 years old) with periodontitis and 9 health elders(65～77 years old).Results:NO(?mol/L)in gingival tissue of elderly patients,health elders,adult patients and juvenile patients were 33.07?12.02,63.53?18.23,55.99?22.40 and 82.15?30.35 respectively.( P
