Effect of maitake (Grifola frondosa) D-fraction on the control of the T lymph node Th-1/Th-2 proportion Inoue A, Kodama N, Nanba H. Department of Microbial Chemistry, Kobe Pharmaceutical University We have already reported that the D-Fraction, a β-glucan extracted from the fruiting body of the maitake mushroom (Grifola frondosa), activates cellular immunity and expresses anti-tumor effects. In this study we investigated the anti-tumor functions of D-Fraction in relation to its control of the balance between T lymphocyte subsets Th-1 and Th-2....

Department of Microbial Chemistry, Kobe Pharmaceutical University A polysaccharide, designated as the D-fraction, extracted from maitake (Grifola frondosa), was reported to have anti-tumor effects by activating macrophages and T cells in C3H/HeN mice in which a Th-1 dominant response was established. In this study using BALB/c mice in which a Th-2 response is genetically dominant, D-fraction reduced the...

However, since NGF is a protein it usually cannot pass through the blood-brain barrier. Recently, researchers have targeted on the...

Department of Bioresource Science, Obihiro University of Agriculture and Veterinary Medicine The effects of mushroom fibers on serum cholesterol and hepatic low-density lipoprotein (LDL) receptor mRNA in rats were investigated. Rats were fed a cholesterol-free diet with 50 g/kg cellulose powder (CP), 50 g/kg maitake (Grifola frondosa)...

Department of Food Science and Nutrition, Faculty of Home Economics, Nishikyushu University We have previously reported that rats with diabetes induced by injecting streptozotocin into neonates showed remarkably lower blood glucose, urine volume, and glucosuria after administration of Maitake (Grifola frondosa). In the present study, we investigated the effects of Maitake on insulin concentration, organ weight, serum composition, and islets...

Dept. of Clinical Nursing, Faculty of Medicine, Toyama Medical and Pharmaceutical University We have investigated D-fraction (MDF) extracted from Grifola frondosa ( Maitake mushroom) on the inducible nitric oxide synthase (iNOS)-mediated nitric oxide (NO) production in RAW264.7 (RAW)...
read moreA Possible Hypoglycemic Effect of Maitake Mushroom on Type 2 Diabetes Patients Konno S, Tortorelis G, Fullerton SA, Samadi AA, Hettiarachchi J, Tazaki H Department of Urology, New York Medical College Two patients diagnosed with Type 2 diabetes had significantly elevated fasting blood glucose (FBG) levels even with administration of glibenclamide, a commonly-prescribed diabetes drug. Both patients were given Maitake mushroom caplets (500 mg) in daily doses, along with their glibenclamide, and experienced a sharp drop in blood glucose levels to...
read moreMaitake SX-Fraction: Possible Hypoglycemic Effect on Diabetes Mellitus Sensuke Konno, Ph.D. Diabetes mellitus is a metabolic disorder characterized by persistent hyperglycemia affecting more than 16 million people in the United States and some 250 million people worldwide.1 The prevalence of diabetes is increasing by 4–5 percent every year with an estimated 40–45 percent of people over 65 years old at risk.2 To enhance peripheral insulin sensitivity, pharmaceuticals, such as troglitazone8 and metformin,9,10 have been used. Although...
