Black raspberry gel may help prevent oral cancersDecember 7th, 2007 - 6:44 pm ICT by admin
Washington, Dec 7(ANI): A recent research has revealed that a gel made from black raspberries may help prevent oral cancers.
According to American Cancer Society statistics, oral cancer is one of the deadliest of all cancers, with about 35,000 new cases each year in the United States and 7,500 deaths annually.
The study conducted at Ohio State University suggested a gel made from black raspberry could offer a means of stopping oral lesions that often leaves patients permanently disfigured.
The research was conducted over 30 people, 20 of whom had identifiable precancerous lesions, and 10 normal controls.
Each of the participants was instructed to gently dry the lesion sites (or a pre-selected control site for the normal participants) and rub the gel into the area four times a day, once after each meal and at bedtime.
The finding revealed about 35 percent of the peoples lesions showed an improvement in their microscopic diagnosis, while another 45 percent showed that their lesions had stabilized.
About 20 percent showed an increase in their lesional microscopic diagnoses. Significantly, none of the participants experienced any side effects.
Susan Mallery, professor in the Department of Oral Maxillofacial Surgery and Pathology at Ohio State Universitys College of Dentistry said that Black raspberries are full of antioxidants that have a role in controlling the cancerous cells.
This gel appears to be a valid means of delivering anthocyanins and other cancer-preventing compounds directly to precancerous cells, since it slowed or reduced lesion progression in about two-thirds of study participants, said Susan.
Oral cancer is a debilitating disease and there is a desperate need for early detection and management of precancerous lesions, she added.
The gel looks deceptively like black raspberry jam, but it certainly does not taste like something you would want to spread on toast, she further added.
The bioadhesive gel, which contains 10 percent freeze dried black raspberries, is devoid of many of the tasty sugars found in native berries.
The research was presented at the American Association for Cancer Researchs Sixth Annual International Conference on Frontiers in Cancer Prevention Research, in Philadelphia, Pennsylvania. (ANI)
