Interleukin-10 (IL-10) is a cytokine with anti-inflammatory activities. IL-10 knockout (KO) mice exhibit severe intestinal inflammation in the presence of normal gut flora. We hypothesized that IL-10 KO mice would also be susceptible to inflammatory periodontal disease resulting in alveolar bone loss (ABL). The purpose of this study was to compare naturally occurring ABL in IL-10 KO and wild type (WT) mice. Twelve IL-10 KO and 12 WT mice, age-(7 months) and sex-(male) matched, were used. Half of the mice were on 129/SvEv and half on C57BL/6J background. Animal heads were defleshed and treated to remove all organic material. ABL …

The environmental carcinogens classified as heterocyclic amines (HCA’s) and the tobacco-specific nitrosamine NNK generally require internal enzymatic activation. This activation occurs via cytochrome P450 (CYP) enzymes and leads to metabolites that bind to human DNA which may in turn cause mutations which may then in turn lead to carcinogenesis. Certain nonnutritive plant compounds termed phytochemicals may protect against HCA and NNK-induced mutagenesis and carcinogenesis. We investigated the potential protective effects of five different phytochemicals of the flavonoid class which naturally occur in citrus. These flavonoids were diosmin, naringin. naringenin, rutin, and quercetin. Our results suggest that naringenin and quercetin were …
