Antimetastatic and immunomodulating effect of water extracts from various mushrooms.

This experiment was conducted to evaluate inhibitory effects against lung metastasis and promotion of splenocytes by water extracts from various mushrooms including Armillaria mellea, Grifola frondosa, Garnoderma frondosa, Codyceps militaris, Hericium erinaceus, Coriolus versicolor, Agaricus Blazei with Lycium Chinense Miller (known as M8). Analysis of carbohydrate using HPTLC showed that beta-glucan and pachyman were some of the major components of M8. Oral administration of M8 resulted in a dose-dependent tendency to inhibit lung metastasis after intravenous injection of colon26-L5 cells. Treatment with M8 resulted in a significant increase of T cell and B cell mitogenic stimuli. The population of CD3, CD19, CD4, and CD8 positive cells increased in a dose dependent manner of M8 administration. However, no significant results were obtained from the population of Mac-1 and NK1.1 positive cells. Oral administration of M8 resulted in the increased production of IFN-gamma and IL-4 by splenocytes stimulated with Con A compared with untreated controls. These results show that M8 has antitumor activities which may be useful as an antimetastatic agent.

Regulatory properties of polysaccharopeptide derived from Coriolus versicolor and its combined effect with ciclosporin on the homeostasis of human lymphocytes.

Collectively, the results reveal certain novel effects of PSP in lymphocyte homoeostasis and suggest potential as a specific immunomodulatory adjuvant for clinical applications in the treatment of autoimmune diseases.[…]

Alternating immunochemotherapy of advanced gastric carcinoma: a randomized comparison of carbazilquinone and PSK to carbazilquinone in patients with curative gastric resection.

A total of 103 patients with advanced gastric carcinoma were randomized after curative surgery to receive an alternate administration of carbazilquinone (CQ) and PSK (Krestin) or carbazilquinone alone. Each course of herapies started 1 week after the surgical operation and therapy schedules consisted of 9 courses. In each course of 6 weeks […]

Adjuvant therapy with protein-bound polysaccharide K and tegafur uracil in patients with stage II or III colorectal cancer: randomized, controlled trial.

PURPOSE: Intravenous fluorouracil and leucovorin for six to eight months is currently a standard adjuvant treatment for Stage III colon cancer; however, this regimen is complex, inconvenient, and has a high intolerability. Adjuvant chemotherapies are claimed for objective response rates with an acceptable safety profile and complexity. We investigated […]
