Endotoxin-inactivating potency of hydrogen peroxide: effect on cell growth
F. A. DeRenzis
An in vitro system was used to study the detoxifying potential of H2O2 on
bacterial endotoxin. L929 fibroblasts were exposed to H2O2-treated and
-untreated endotoxin. Growth and viability assays were made at 24, 48, 72,
and 96 h. The cultures exposed to H2O2-treated endotoxin showed a normal
growth rate, whereas the cultures exposed to untreated endotoxin displayed
a substantial reduction in growth. Implications are presented as to the
potential role of H2O2 in the pathogenesis and treatment of periodontal
disease.
