Heavy metal pollution is a serious problem for Lentinula edodes; however, the treatment of contaminated L. edodes has seldom been studied. This study investigated the removal of cadmium (Cd) from contaminated L. edodes and its lentinan by complexation and coagulation. Some influencing factors, such as pH, medical dosage, and preoxidation were examined. Cd complexation from contaminated L. edode...

Six polysaccharide preparations, lentinan, LC-11, LC-12, LC-13, EC-11, and EC-14, were isolated from the watersoluble extracts of Lentinus edodes (Berk.) Sing., an edible mushroom, by fractional precipitation with ethanol and cetyltrimethylammonium hydroxide, fractional solubilization with acetic acid, and diethylaminoethyl cellulose column chromatography. The first two polysaccharide preparati...

Several researchers have demonstrated that protein-bound polysacharide complexes such as PSK or PSP, derived from Coriolus versicolor ; or Lentinan derived from Letinula edodes are the most important component responsible for immunoenhancing and anti-tumour activities. In fact PSP is responsible for oxidative stress relief in cancer patients because it mimicks superoxide dismutase activity due ...

A system for assessing the anti-inflammatory effects of food factors was developed by establishing a co-culture system with intestinal epithelial Caco-2 cells and macrophage RAW264.7 cells. The results indicate that fucoidan and lentinan exhibited different suppressive effects on interleukin-8 (IL-8) mRNA expression in Caco-2 through tumor necrosis factor-alpha (TNF-alpha) production from RAW26...

BACKGROUND Immunotherapy is useful for the prevention of the post-operative recurrence of some types of cancer and, in combination with certain anticancer drugs, is expected to prolong survival time. However, the clinical efficacy of immunotherapy alone against advanced cancer has not yet been demonstrated. CASE REPORT A 67-year-old woman with ovarian cancer who had undergone post-operative a...

In rare occasions, ingestion of raw or undercooked shiitake mushrooms (Lentinus edodes) can result in a unique dermatologic manifestation known as flagellate dermatitis (SFD). The diagnosis SFD is often overlooked due to the rarity condition and commonality mushroom consumption. As consumption increases globally, rise cases may follow suit. Therefore, awareness presentation clinical background ...

This contribution proposed a novel electrochemical approach for lentinan (LT) determination using medaylene blue (MB) as probe. The interaction conditions of LT with MB were carefully studied by cyclic voltammetry. Under the optimum conditions, the cyclic voltammetric curve of MB showed a pair of convertible oxidation and deoxidization peaks with the peak potentials of -0.157 V and -0.191 V, re...

A number microbial components and plant products such as polysaccharides, lentinan, levamisole, schizophyllan, oligosaccharides, muramyl dipeptide and yeast derivatives have been used as immunostimulants in aquaculture to stimulate the innate immune system of fish and shrimp. Among the all the immunostimulants examined, Betaglucans were found to be most promising immunostimulants, which are use...
