Administration of extract of mushroom Phellinus linteus induces prostate enlargement with increase in stromal component in experimentally developed rat model of benign prostatic hyperplasia

Orally administered mycelial culture of Phellinus linteus exhibits antitumor effects in hepatoma cell-bearing mice

AIM OF THE STUDY

The aim of this study was to evaluate the anticancer effect of a mycelial culture from Phellinus linteus PL-7 (MCPL-7) and to elucidate its potential mechanism in vivo.

MATERIALS AND METHODS

SCID CB-17 mice received a transplant of Hep3B cells followed by daily MCPL-7 administrations for 8 weeks. Following tumor implantation, groups C-E were subcutaneously administered 50 mg/kg, 100 mg/kg, or 250 mg/kg MCPL-7 powder per day, respectively, for 8 weeks. Groups A and B received saline solution subcutaneously for 8 weeks.

RESULTS

MCPL-7 administration induced a significant reduction in tumor size and was associated with a significant increase in T cell numbers; IL-12, IFN-γ and TNF-α secretion; NK cell activity; and phagocytic ability. Therefore, increased numbers of CD4(+) cells could have been caused by greater numbers of dendritic cells and macrophages in the spleen. Furthermore, the activation of dendritic cells and macrophages resulted in increased IL-12 secretion, which could upregulate NK cell activation. The increased secretion of IL-12, IFN-γ, and TNF-α enhanced the activity and phagocytic ability of NK cells. Thus, MCPL-7 may provide a potential therapeutic approach for both immunomodulatory and antitumor effects.

What patients take without telling you: holistic approach for BPH

The use of botanicals and supplements have markedly increased in men that are seeking increased protection against the potential onset and symptomatic relief of lower urinary tract symptoms that are commonly experienced with benign prostatic hyperplasia (BPH). While this implies a positive trend and considers that men are taking a more active role in health and prevention, dialog between the patient and the clinician is often deficient. This may be due to a number of factors including both the patients' inability to report about the use of certain agents and the clinicians' inability to ask. Moreover, the sense that natural agents may lack side effects coupled with ineffective communication between the doctor and patient could result in potential adverse interactions. We have performed a comprehensive search of articles published from 1990 to 2005 using the Medline databases in order examine clinical data on the most commonly researched herbs for BPH. We provide a brief update on the state of the research.
