Previously, it was shown that milk fermented with lactic acid bacteria lowers blood pressure, suggesting that metabolites or components of the bacteria have hypotensive action. To examine whether one of lactobacilli, Lactobacillus johnsonii La1 (LJLa1), a probiotic strain adhesive onto intestinal epithelial cells, or its metabolite has hypotensive action,(More)
In order to investigate the risk-reducing effects of coffee in metabolic syndrome, we performed a study in mice fed a high-fat diet with added coffee and analyzed gene expression in liver and adipose tissues using cDNA microarray. Male C57BL/6J mice were raised for 8 weeks on either a normal diet (N group), a high-fat diet (HF group), or a high-fat diet(More)
To exert beneficial effects for the host, for example, improving the intestinal microflora, a probiotic must reach the intestine as a viable strain. These properties must be demonstrated by in vitro as well as in vivo methods. However, only a few well-designed human clinical studies have shown these properties. Lactobacillus johnsonii La1 has been shown to(More)
Probiotics have potential to improve host immunity; however, there is less evidence showing their efficacy against infections and nutritional status in the elderly. We conducted a double-blinded feeding trial in the elderly to elucidate the effect of fermented milk containing Lactobacillus johnsonii La1 (LC1) on infections and nutritional status.(More)
Food and beverages rich in polyphenols with antioxidant activity are highlighted as a potential factor for risk reduction of lifestyle related diseases. This study was conducted to elucidate total polyphenol consumption from beverages in Japanese people. Total polyphenol (TP) contents in beverages were measured using a modified Folin-Ciocalteu method(More)
Oral administration of Lactobacillus casei reportedly reduces blood glucose concentrations in a non-insulin-dependent diabetic KK-Ay mouse model. In order to determine if other lactobacillus strains affect glucose metabolism, we evaluated the effect of the probiotic strain Lactobacillus johnsonii La1 (LJLa1) strain on glucose metabolism in rats. Oral(More)
OBJECTIVE Protein-energy malnutrition (PEM) is a serious nutritional problem that causes immune dysfunction in elderly people. Probiotic lactic acid bacteria may potentially modify immunity; however, there is little evidence to elucidate the influence of these bacteria on PEM in the elderly. METHODS The immune modulation effects of lactic acid bacterium(More)
The effects of Lactobacillus johnsonii La1 (LC1) on Helicobacter pylori colonization in the stomach were investigated. H. pylori colonization and gastritis in LC1-inoculated Mongolian gerbils were significantly less intense than those in the control animals. LC1 culture supernatant (>10-kDa fraction) inhibited H. pylori motility and induced bacterial(More)
SUMMARY In a recent study, we obtained some evidences that probiotic strain Lactobacillus affects the autonomic nerve activities and regulates blood glucose and cardiovascular function. In the study presented here, we found that long-term ingestion of the lactobacillus strain Lactobacillus paracasei ST11 (NCC2461) reduced body weight and abdominal fat(More)
Bacterial exposure in infancy may be one of the determinants of atopic dermatitis (AD) morbidity in later life. Some clinical studies have shown that an intake of probiotics reduced the risks of AD in children; however, the timing and duration of administration for the prevention of AD still remain unclear. The aim of this study was to evaluate the effects(More)
