Chemoprevention of carcinoma prostate: a review.
Ansari MS, Gupta NP, Hemal AK.
A twenty-year review of the literature on chemoprevention of prostate cancer was undertaken by the authors. They found that nutritional factors including reduced fat intake, supplemental vitamin E, vitamin A, vitamin C, vitamin D, Lycopene and selenium may have a protective effect against prostate cancer. The authors concluded that on the basis of numerous studies, dietary and nutritional intervention should occur at the onset of prostate cancer.

Anti-oxidant vitamins and steroid responsive nephrotic syndrome in Indian children.
Mathew JL, Kabi BC, Rath B.
The authors acknowledge that nephrotic syndrome may be a consequence of an imbalance between oxidant and anti-oxidant activity. In the present study, the levels of micronutrient anti-oxidant vitamins (vitamin E, vitamin C, carotene and riboflavin) in 30 Indian children with steroid responsive nephrotic syndrome were investigated and 30 sibling controls. The authors found that mean vitamin E, vitamin C and carotene were significantly lower during the proteinuric phase of the disease, and there was decreased erythrocyte riboflavin activity. The vitamin levels improved during hospitalization but did not become normal. The authors concluded that these vitamins were active in performing their anti-oxidant function, as indicated by significant depression in their levels during the acute (proteinuric) phase, followed by partial recovery during remission. They conclude that steroid responsive nephrotic syndrome in children is associated with oxidative stress.

Mantovani G, Maccio A, Madeddu C, Mura L, Gramignano G, Lusso MR, Murgia V, Camboni P, Ferreli L, Mocci M, Massa E.
The authors set out to test the capacity of several different antioxidants to reduce reactive oxygen species (ROS) levels, increase glutathione peroxidase (GPx) activity and reduce the serum levels of proinflammatory cytokines IL-6 and TNFalpha. Fifty-six patients with advanced stage cancer were studied. The authors used the following antioxidants: alpha lipoic acid or carboxycysteine-lysine salt, amifostine, reduced glutathione, vitamin A plus vitamin E plus vitamin C. Antioxidant treatment was given for 10 consecutive days. Results of the study showed that all single antioxidants tested were effective in reducing the ROS levels and three of them in increasing GPx activity.

Diet and Oral, Pharyngeal, and Esophageal Cancer.
Chainani-Wu N.
Cancers of the upper digestive tract, including those arising in the oral cavity, pharynx, and esophagus, present a significant public health problem worldwide. These cancers are associated with high morbidity and mortality, and identification of protective factors is very important. The results of 35 epidemiological studies were examined to determine the protective role of dietary components against development of oral, pharyngeal, and esophageal cancers. It was concluded that there is sufficient evidence to point to a preventive role of vegetable intake, including green vegetables, cruciferous vegetables, and yellow vegetables, total fruit intake, and citrus fruit intake. Yellow fruits are likely to be protective. Carotene, vitamin c, and vitamin E are protective, most likely in combination with each other and other micronutrients.

The use of antioxidant therapies during chemotherapy.
Drisko JA, Chapman J, Hunter VJ.
This study was undertaken because many cancer patients use alternative medicine along with their conventional therapy. The authors reviewed four common antioxidants: vitamin E (mixed tocopherols and tocotrienols), beta-carotene (natural mixed carotenoids), vitamin C (ascorbic acid), and vitamin A (retinoic acid). They acknowledge that antioxidants act as electron acceptors as well as therapeutic biologic response modifiers. They conclude that antioxidants may be beneficial when combined with cancer chemotherapy. They recommend randomized controlled trials to evaluate the safety and efficacy of adding antioxidants to chemotherapy. Such a trial they say is now under way in newly diagnosed ovarian cancer at the University of Kansas Medical Center.

Protective role of oral antioxidant supplementation in ocular surface of diabetic patients.
Peponis V, Papathanasiou M, Kapranou A, Magkou C, Tyligada A, Melidonis A,
Drosos T, Sitaras NM.
Diabetic patients have a high rate of oxidative stress indicated by high levels of nitric oxide (NO), which is a free radical. In this study 50 non-insulin diabetics were given vitamin C and vitamin E for 10 days and the levels of nitrite were measured before and after supplementation. The results indicated a significant reduction in nitrite levels after 10 days of vitamin C and vitamin E. Thus these vitamins are seen has having a protecting role from free radical damage.

In previous studies, vitamin C and vitamin E were found to reduce preeclampsia. This study looked at 79 high-risk women who were taking vitamins, 81 women taking placebos and they were compared with 32 low risk women who were not taking vitamins. The results indicated abnormal oxidative stress, placenta function, and low ascorbic acid levels in the placebo group compared with the low risk women. The women who received the vitamins had similar values as the low risk women. Thus, antioxidants improved the biochemistry of high risk preeclampsia women.

Effect of antioxidants (vitamin C, E and turmeric extract) on methimazole-induced hypothyroidism in rats.
Deshpande UR, Joseph LJ, Patwardhan UN, Samuel AM.
The degree to which antioxidants protect against the effects of methimazole (MMI) was the subject of this study on rats. Rats were fed either MMI, MMI plus vitamin C, MMI plus vitamin E or MMI plus turmeric extract. Rats, which were fed MMI plus vitamins or turmeric had reduced thyroid gland weight, had less suppressed T3 and T4 levels and less increase in cholesterol levels. Thus antioxidants were found to have positive effects on the thyroid gland.

Effects of young barley leaf extract and antioxidative vitamins on LDL oxidation and free radical scavenging activities in type 2 diabetes.
Yu YM, Chang WC, Chang CT, Hsieh CL, Tsai CE.
Diabetic patients (36) received either barley leaf extract (BL), or vitamin C and vitamin E (CE), or BL +CE daily for 4 weeks. The effect of the treatment on LDL levels was measured. The results indicated that vitamin C and E with BL are more effective antioxidants and my help prevent vascular diseases in type II diabetics.

Antenatal supplementation of antioxidant vitamins to reduce the oxidative stress at delivery--a pilot study.
Bolisetty S, Naidoo D, Lui K, Koh TH, Watson D, Whitehall J.
Premature babies are deficient in antioxidants and therefore at risk of free-radical related diseases. In this pilot study, 5 mothers at risk of premature delivery were given vitamin C, vitamin E and beta-carotene daily until delivery. The control group received no supplements. The results indicated that the vitamins reduced oxidative stress at birth. The author calls for larger scale studies of this relationship.

Topical antioxidant vitamins E and C prevent UVB-radiation-induced peroxidation of eicosapentaenoic acid in pig skin.
Moison RM, Beijersbergen van Henegouwen GM.
While eicosapentaenoic acid protects against UV-radiation, it is also likely to undergo oxidative degradation thus reducing its effects. Pig skin was used to test whether vitamins E and C protected against the oxidation of eicosapentaenoic acid. It was found that both vitamin C and vitamin E completely protected against peroxidation from UVB radiation making these antioxidants beneficial in combination with eicosapentaenoic acid.
