Low-level chemiluminescence (CL) appeared on addition of hydrogen peroxide to human saliva and then decayed slowly. Azide (10 microM) inhibited CL by about 50% and deuterium oxide (99.75%) enhanced it about twofold. 1,4-Diazabicyclo[2,2,2]octane (50 mM) and tryptophan (10 mM) were also enhancing, which suggests that singlet oxygen participates in this CL. The optimal pH for CL was around 8.5. Molecular oxygen was produced on addition of hydrogen peroxide to human saliva with a time course… CONTINUE READING
