This study was supported in part by a Grant in Aid from AOA Japan Co., LTD., and also from the Uchida Science Promotion Foundation, Niigata, Japan. Abstract: There is strong evidence that oxidative stress participates in the etiology of neurodegenerative diseases such as Parkinson’s, and Alzheimer’s diseases. Moreover, emotional stress effects in the central nervous system play a vital role in homeostasis. The protective effect of anthocyanins on the cerebral oxidative stress was studied using the whiskers cut model. In mice, such treatment causes psychological or emotional distress leading to oxidative stress in tissues. To investigate the in vivo antioxidant activity of anthocyanins, an extract of Vaccinium myrtillis L., an anthocyanin mixture, was orally administered (100 mg/kg of body weight.) to mice for 7 days, and then psychological stress was assessed by cutting off their whiskers. Whisker removal increased both protein carbonyl formation and lipid peroxidation in the brain, heart, kidney, and liver. Further, the levels of oxidative markers showed regional differences in the brain. Concomitantly, dopamine neurotransmitter levels were altered in both the midbrain and the brain cortex. Orally administered anthocyanins were also active in the brain, suppressing stress-induced cerebral oxidative stress and dopamine abnormalities in distressed mice. These effects of anthocyanin treatment suggest their possible usefulness for the treatment of cerebral disorders related to oxidative stress.

These plant pigments are more than coloring agents for fruit juices, wine, and other beverages. They also contain an array of health- promoting benefits. Eaten in large amounts by primitive humans, anthocyanins are antioxidant flavonoids that protect many body systems. They have some of the strongest physiological effects of any plant compounds, and they are also things of beauty: anthocyanins provide pigment for pansies, petunias, and plums. (Anthocyanins are a separate class of flavonoids from proanthocyanidins, discussed in NSN 2000;5(6): 231-4.) Who loves ya.

From: Michael B on 20 Aug 2008 22:30 Hey, Rusty, you're not going to share the info on a common food that contains a derivative of the anthocyanidin delphinidin which interferes with the dangerous hydroxyl radical-generating system—a major source of oxidants in the body? I would have thought you would have been touting that a long time ago. Hint-it's from one of the nightshades. And, BTW, anyone else is welcome to join me in our thread. Shucks, we all know by now that if Rusty didn't want me on the threads he starts, he wouldn't include alt.med.fibromyalgia in the initial crosspostings. Does everyone also know what the hydroxyl radical is? Some of you don't? Why, that's disappointing. But since Rusty is so set on telling us about oxidative stress, perhaps you can prevail on him to explain it. After all, it's near the root of it all. Go ahead, ask him to explain it. He's really waiting for a good opportunity to make sure you all understand it as well as he does.
