Depletion of Antioxidants Linked to Brain Tumors

Numerous studies have shown that exposure to microwave radiation and other EMR depletes the body of a number of its naturally occuring antioxidants like SOD (Super Oxide Dismutase) and Glutathione. The following study shows that these antioxidants are also depleted in people with brain tumors, especially malignant brain tumors. This offers another link between exposure to microwave and other EMR and brain tumors. It also hints to us that perhaps we need to take antioxidants in supplement form to guard against the negative effects of being exposed to our daily doses of ambient radiation. And the insanity continues...

The erythrocyte levels of the antioxidant enzymes SOD and GPx, and serum levels of antioxidants vitamins β -carotene and β -tocopherol were estimated in various types of brain tumors, and were compared with the levels in controls. Statistically significant (P<.001) diminished levels of β - carotene, β -tocopherol, SOD and GPx, were observed in all the brain tumor patients as compared to controls. Malignant tumor also showed a relative decrease in antioxidant levels as compared to benign tumors. Comparison of histopathological sections of brain tumors also suggested a inverse relationship between antioxidant level and grades of malignancy. Marked decrease in antioxidant levels may have a role in genesis of considerable oxidative stress in brain tumors. Further more, the degree of decline in antioxidant levels may indicate severity of malignancy in brain tumors.
