|Title:||Pycnogenol® Protects Against Ionizing Radiation As Shown In The Intestinal Mucosa Of Rats Exposed To X-rays|
De Almeida S.M.
|Abstract:||X-rays and gamma radiation delivered to the abdominal region for cancer treatment encompasses severe damage to the intestinal mucosa, which significantly impairs a patient's quality of life. To a great extent the deleterious effects of x-radiation originate from radiolysis-induced reactive oxygen species. The well-researched powerful antioxidant Pycnogenol® was administered orally to rats prior to x-irradiation with 15 Gy. Histological sections of the intestines showed a dramatically better condition of the mucosal layers compared with the irradiated control animals administered water without Pycnogenol®. Pycnogenol® treatment significantly preserved the height and number of villi as well as the glandular layer and a diminished number of congested vases were present. No intestinal alterations were seen in control animals receiving Pycnogenol® in the absence of radiation. It is concluded that Pycnogenol® provides significant protection from ionizing radiation damage. Copyright © 2006 John Wiley & Sons, Ltd.|
