Stress May Increase The Risk Of Sun Induced Skin Cancer
Mice were exposed to ultraviolet B radiation, the type of solar radiation that causes sunburn and skin cancer. A group of these mice were then exposed to the smell of fox urine to induce stress,foxes are a natural mouse predator. Exposure to fox urine started 14 days beore ultraviolet B radiation and was continued 3 times a week for the duration of the study. The second group was also exposed to the ultraviolet B radiation but without the stress inducing fox odor. The mice with stress developed their first cancerous skin tumor by the eight week of the study and 35% of these mice developed skin cancer. The mice without the stress didn't develop the skin cancer until the 21st week of the study and only 7% of these mice developed tumors. This may be important news for people who are at high risk of developing skin cancer. The study appears in the December 2004 issue of the Journal of the American Academy of Dermatology.
Resveratrol, Green Tea, and Diallyl Sulfide Protect Esophagus From Esophageal Cancer Causing Nitrosamine
N-Nitrosomethylbenzylamine or NMBA is a cancer causing chemical in the nitrosamine family of cancer causing chemicals. NMBA is routinely injected into the esophagus of rats because it depedably causes esophageal cancer allowing scientists to study this cancer process. Esophageal cancer is increasing in incidence. The researchers added ellagic acid to the chow of one group of rats, they switched the water to green tea in a second group, or fed another group of rats diallyl sulfide, an organosulfate found in aged garlic. All three products significantly inhibited the mutation causing effects of injected NMBA in the esophagus of rats - in other words they decreased significantly the cancer causing activity of this dangerous chemical. The study is published in the journal Nutrition and Cancer 2004;50(2):168-73.
Royal Jelly Contains Naturally Ocurring Antibacterial, an Anti-Yeast Agents
Three antimicrobial gaents were isolated from honeybee royal jelly. They were Jellenes I through III. These peptides (proteins) were effective against a wide range of yeasts, and both Gram Positive and Gram Negative bacteria. These peptides are only found in royal jelly. The study is published in the June 25th, 2004 issue of Peptides.
