In this study researchers in the Cardiology department, University Hospital,
Zurich, gave 22 heart transplant recipients either Cocoa Polyphenol rich dark
chocolate or chocolate without the Cocoa polyphenols in a placebo-controlled
study. The Cocoa Polyphenols significantly opened up the coronary arteries improving
blood flow to the heart and there was a decreased tendency to form an improper
blood clot due to platelet clumping in the heart. There was also a significant
jump in antioxidant activity in the Cocoa Polyphenol receiving patients. The
study is published in the November 20th, 2007 issue of Circulation, a journal
of the American Heart Association.
Mushroom shows potential as prostate cancer fighter
The Reishi mushroom (Ganoderma lucidum) suppresses mechanisms involved in the
progression of prostate cancer according to scientists at the University of
Haifa in Israel. In the study the researchers evaluated the ability of extracts
from 68 fungi to interfere with the androgen or male hormone receptor within
the cell to inhibit the growth of the cancer. The compounds from the fungi were
extracted with solvents that would select molecules small enough to enter the
diseased cells.
The researchers found 11 extracts that interfered with a major control for prostate
cancer growth, in this case androgen receptor activity, by more than 40 percent,
and 14 were also active for cancer cell growth inhibition. Of these active compounds,
extracts derived from Reishi exerted the greatest interference on androgen receptor
function and cancer cell development. Bioactive metabolites from Reishi mushroom
could yield an anti-prostate cancer drug. This study adds to evidence from research
published in the October 2007 issue of the International Journal of oncology
showing that Reishi suppressed cancer cell growth and inhibited androgen activity
in prostate cancer cells.
