Extraction, purification and properties of water-soluble polysaccharides from mushroom Lepista nuda.

Lepista nuda has high nutritional and medicinal value, especially has high antioxidant, antitumor and antiviral activities. Based on results of single factor experiment, response surface methodology was used to optimize the extraction conditions of polysaccharides (LNP). Macroporous resin D301 was used to decolorization, and its technological conditions were determined by orthogonal experiment.

Study on the immunomodulatory activity of a novel polysaccharide from the lichen Umbilicaria Esculenta.

Umbilicaria esculenta possesses nutritional properties, such as antioxidant, antithrombotic and lipid peroxidation inhibitory activity. The immune effects of its polysaccharide (Umbilicaria esculenta polysaccharide, UEP) on murine macrophages RAW264.7 were investigated for the first time.

Extraction, preliminary characterization and in vitro antioxidant activity of polysaccharides from Oudemansiella radicata mushroom.

Oudemansiella radicata mushroom has many functions. Optimal condition of extracting its polysaccharides (ORP) with a yield of 5.85 ± 0.

Macrophage immunomodulatory activity of the polysaccharide isolated from Collybia radicata mushroom.

Polysaccharides from Collybia radicata mushroom (CRP) possess many functions, such as antiviral, anti-aging and hypolipidemic activities. However, little is known about their immunomodulatory activity. To address this issue, we did a thorough research into their immune effects on murine macrophages.

[Lead impairs ability of learning and memory and affects expression of synaptosomal-associated protein-25 in hippocampus of offspring].

Objective: To find the effects of lead taken by pregnant mice on learning and memory and the expression of synaptosomal-associated protein (SNAP)-25 mRNA and protein, in order to reveal the mechanism of neurotoxicity induced by lead.

Methods: Lead exposure was conducted through freely drinking the corresponding lead acetate solutions with dosages of 0.3, 1.
