Study Suggests Green Tea May Support the Medical Treatment of Stomach and
Colon Cancer
BOULDER, Colo., May 14 /PRNewswire/ -- Green tea consumption may promote
cancer-preventive effects in people at risk for cancer in addition to
supporting the medical treatment of some kinds of cancer, according to a study
in the May/June 2008 issue of Alternative Therapies in Health and Medicine, on
newsstands now.
In a study to establish whether green tea has anti-cancerous potential in
human stomach and colon cancers, 6 cancerous and 6 non-cancerous adjacent
human gastric tissues and 7 cancerous and 7 non-cancerous adjacent colon
tissues were obtained from patients who underwent surgery for stomach and
colon cancer in the Ankara University Faculty of Medicine, Department of
General Surgery, Turkey. The tissues were treated with aqueous green tea
extract at 3 different final concentrations (0.05%, 0.5%, and 1.25%) for
1 hour. Activity assays were performed on the same samples without green tea
extract. Protein levels of the tissues were studied and adjusted to equal
concentrations.
Xanthine oxidase (XO) and reduced adenosine deaminase (ADA) enzyme
activities were measured before and after the incubation period. Percentage
changes for the 3 different concentrations of green tea extract versus no
green tea extract were calculated.
In both cancerous and non-cancerous tissues, XO activities were found to
increase in correlation with increased extract concentrations in both cancer
types. Additionally, ADA activity was found to decrease in the cancerous part
of stomach tissue and to increase in the non-cancerous part.
"[While] further in vivo studies should be conducted about the effects of
green tea in colon and gastric cancers, our study suggests that green tea
consumption may promote cancer-preventive effects in people at risk for
cancer, in addition to supporting the medical treatment of some kinds of
cancers," the authors said.
