A lack of specific and effective treatment for Type 2 diabetes has long demanded to establish a better therapeutic modality. As the maitake mushroom extract, SX-fraction (SXF), has been shown to have anti-diabetic activity, we investigated if SXF would demonstrate such an activity in diabetic KK-Ay mice. Test materials included original maitake mushroom (Orig-M), two different doses of SXF [low dose of SXF (L) and high dose of SXF (H)], and Actos  (ACT). Two hundred KK-Ay mice were divided into five experimental groups: (A) Sham (none given), (B) Orig-M, (C) SXF...

It has been long demanded that a better treatment modality for type 2 diabetes mellitus (T2DM) needs to be established, but few suitable regimens have yet been found. We came across the bioactive mushroom extract, SX-fraction (SXF), which appeared to have a hypoglycemic effect. Hence, we investigated if SXF would actually have such an effect, as well as its possible hypoglycemic mechanism. A small-scale clinical study including ten volunteered T2DM patients was conducted. They took a SXF tablet (500 mg) three times a day for 4 weeks, as the fasting blood glucose...

We have been studying anticancer effect of Maitake D-fraction (PDF), isolated from maitake mushroom, on various cancer cells in the past 24 years. PDF was highly effective on those cells, profoundly reducing their cell viability. However, we have not yet examined PDF on other cancer cells, particularly pancreatic, cervical, and small-cell lung cancer cells, which had been known to be dismal and deadly. Hence, we investigated if PDF alone or its combination with vitamin C (VC) might have a significant anticancer effect against those cancer cells. Pancreatic cancer...

Polysaccharide extracted from Grifola frondosa (GFP) was selected in this study. After preliminary separation, four factions were collected, named GFP-F1, GFP-F2, GFP-F3 and GFP-F4. GPF-F2 was further separated into two fractions, namely GFP-N1 and GFP-N2. The molecular weight of GFP-N1 and GFP-N2 was 3.323×103kDa and 10.8 kDa, respectively. GFP-N1 was composed of glucose and galactose and 1→3, 1→4, and 1→6 glycosidic bonds. GFP-N2 was composed of glucose, galactose and mannose and 1→2, 1→3, 1→4, and 1→6 glycosidic bonds. GFP could...

This study aimed to analyze the pharmacokinetic parameters of 1,3-beta-glucans from Maitake Pro4X in BALBc mice through oral and Intra Venous (IV) administration. The objectives were to determine the following parameters: Tmax, Cmax, t1/2, ta1/2, Ke, Ka, Clearance, Vd, Cp0, and AUC. Additionally, the tissue distribution of 1,3-beta-glucans after oral and IV administration of Maitake Pro4X was examined to identify the organs involved in absorption, elimination, and distribution. The results comparison  indicated that certain elimination constants were similar in both...

This study shows that anticancer activity of BCNU is significantly potentiated with PDF in T24 cells. This is rather attributed to inactivated Gly-I and increased oxidative stress. Therefore, PDF appears to have a chemosensitizing effect capable of enhancing BCNU cytotoxicity, which may offer an alternative, improved therapeutic option for bladder cancer.
