Fig. 3From: Combined antioxidant effects of Neem extract, bacteria, red blood cells and Lysozyme: possible relation to periodontal diseaseModulation of luminescence by red blood cells (RBC) and complexes of P. gingivalis pre-coated with Neem leaf extract. Total oxidants generated by the cocktail, were measured along time by luminescence. Time-dependent chemiluminescence patterns of oxidant scavenging abilities (OSA) induced by P. gingivalis pre-coated with Neem (50 μM GAE), RBC alone, and combinations of RBC and P. gingivalis pre-coated with NeemBack to article page
