We have investigated the possibility of oral administration of ovalbumin (OVA) to prevent a secondary antibody response and interrupt reaginic antibody production. Repeated feeding seems necessary for both. Quality of results was dependent on the number of ingestions. Differences in abrogation of antibody response between mice strains were observed. Best results were obtained with AKR mice, goo...

National surveys are important tools for public health surveillance and thus key elements in monitoring health conditions and system performance. In the field of oral health, such surveys began with the oral health survey in 1986 and later in 1996 and with the SBBrasil Project in 2003. The 2010 edition of SBBrasil is the principal oral health surveillance strategy for the production of primary ...

Rikkosan is a traditional Kampo medicine using the control of oral pain caused by dental caries, pulpitis, periodontitis and stomatitis. In order to provide evidence for its clinical effects, we herein investigated whether Rikkosan inhibits the production of pro-inflammatory substances in human and mouse models of inflammation. Rikkosan alone did not induce prostaglandin E2 (PGE2) production, b...

We previously reported that oral administration of luteolin can inhibit serum tumor necrosis factor (TNF)-alpha production and several inflammatory and allergic models. We investigated here the effect of various flavonoids which resemble luteolin in structure. Lipopolysaccharide (LPS)-induced TNF-alpha production from macrophages was inhibited by treatment with flavone (luteolin, apigenin, and ...

Both Candida albicans and lactobacilli are common colonizers of carious lesions in children and adolescents. The purpose of this study is to compare the velocity of acid production between C. albicans and several Lactobacillus species at different pH levels and concentrations of glucose. Washed, pure resting-cell suspensions were obtained by culturing a total of 28 oral isolates comprising the ...

Nitric oxide (NO) is a free radical which is produced from a wide variety of cells and tissues in the human body. NO is involved in the regulation of many physiological processes, such as vascular relaxation, neurotransmission, immune regulation, and cell death. NO is generated by nitric oxide synthase (NOS), which has three identified isoforms: neuronal type NOS (nNOS), endothelial type NOS (e...

OBJECTIVE To examine the effects of oral contraceptive use on maximum force production in young women. METHODS In the study, 21 female subjects (14 pill users and seven eumenorrheic controls) took part. All pill using subjects had been taking a combined, monophasic oral contraceptive pill for at least 6 months. Maximum dynamic and isometric leg strength, maximum isometric strength of the firs...

We have previously demonstrated that Lactobacillus paracasei NCC2461 may help to prevent cow's milk allergy in mice by inducing oral tolerance to beta-lactoglobulin (BLG). To investigate the mechanisms involved in this beneficial effect, we examined the possibility that L. paracasei induces tolerance by hydrolyzing BLG-derived peptides and liberating peptides that stimulate interleukin-10 (IL-1...

Betel quid (BQ) chewing is an etiologic factor of oral cancer and submucus fibrosis (OSF). Keratinocyte inflammation is crucial for the pathogenesis of cancer and tissue fibrosis. We found that areca nut (AN) extract (100-400 micro g/ml) induced PGE2 production by KB cells by 2.34- to 23.1-fold and also TNF-alpha production by gingival keratinocytes (GK). Arecoline (0.2-1.2 mM) elevated PGE2 pr...

The objective of this study was to investigate the effects of concentrations of forages and dried distillers grains with solubles (DDGS) on production of lactating dairy cows. Twelve Holstein cows were assigned randomly to replicated 4 × 4 Latin squares in a 2 × 2 factorial arrangement of treatments. Diets were formulated containing low forage (LF; 41% of diet DM) or high forage (HF; 60% of die...
