Peripheral PMN cell activity in relation to treatment of juvenile periodontitis.

Ten patients with untreated juvenile periodontitis (JP) showing an increased generation rate of free oxygen radicals from their peripheral polymorphonuclear neutrophils (PMN) as measured by luminol enhanced chemiluminescence (CL) were rechecked after treatment. The PMN cells from eight patients still reacted with higher CL after stimulation with Staph. aureus opsonized with autologous serum when related to pair-matched controls.

Influence of plasma components on luminol-enhanced chemiluminescence from peripheral granulocytes in juvenile periodontitis.

The generation rate of free oxygen radicals as measured by maximal light intensity of luminol-enhanced chemiluminescence from peripheral blood granulocytes (PMN) stimulated with differently opsonized Staphylococcus aureus was studied in 13 patients with juvenile periodontitis (JP) and pair-matched, healthy controls. Plasma proteins related to inflammation were also assayed. When stimulated with bacteria opsonized with autologous serum, the PMN from the JP patients showed a more intensive chemiluminescence than did their pair-matched controls (p less than or equal to 0.
