TL;DR: Antioxidant activities of WGLE supplementation further extend in suppressing activities of antioxidant related enzymes, such as glutathione peroxidase (GSH-Px), catalase (CAT) and superoxide dismutase (SOD), in organs of diabetic rats.

TL;DR: Higher values of Ca to ash ratios, as well as bone mineral density and bone mineral content in femurs and tibias of the phosvitin peptides groups, suggested that phosVit in peptides improved bioavailability of Ca and thus increased incorporation of Ca into bones.

TL;DR: In this article, the authors examined both wild and cultivated ginseng leaves for their various antioxidant activities and found that the wild leaves contained more phenolics (9.71 g:4.87 g/100 g, dry basis) and flavonoids (3.03 g:2.34 g/ 100 g) than the cultivated leaves.

TL;DR: The cytotoxicity of peritoneal macrophages against B16 tumor cells was significantly enhanced by 25–38% during 15 days of oral administration of soluble glucan, indicating that soluble glucAn stimulates the immune functions of macrophage.
Abstract: The glucan that was produced by glucosyltransferases (GTFs) from Streptococcus mutans was examined for its stimulating functions toward murine peritoneal macrophages. Soluble glucan was obtained by the reaction with cell-free crude GTFs and sucrose, followed by ethanol precipitation, dispersion in water and re-precipitation by ethanol. Soluble glucan, those average molecular weight was about 3×105, was composed of mixture of α-1,6 and α-1,3 linkages in a 3:1 ratio. When 30 and 60 μg/ml of the glucan was incubated with peritoneal macrophages, the lysosomal phosphatase activity was increased in a dose-dependant manner, indicating that soluble glucan may activate macrophages. To examine its effects on the various functions of macrophages, soluble glucan was orally administered daily at a level of 100 mg/kg of body weight to C57BL/6 mice. Significant stimulation of the production of H2O2 by the macrophages was observed without any increase in NO production. The production of tumor necrosis factor-α (TNF-α) by...
